Return to Sports in Patients Aged 50 Years or Younger After Robotic-Assisted Patellofemoral Arthroplasty: A 10-Year Experience Reporting High Clinical Benefits and High Patient Satisfaction With Return to an Active Lifestyle

Background: Limited data are available on return to sports and patient psychometric ratings of success after patellofemoral arthroplasty (PFA) in younger patients with high expectations to return to an active lifestyle. Purpose/Hypothesis: The purpose of this article was to determine the role of PFA and its success in meeting patient expectations regarding the return to low-impact recreational sports and an active lifestyle in younger, active patients. It was hypothesized that PFA would allow younger patients to return to low-impact sports and an active lifestyle and achieve high patient psychometric ratings. Study Design: Case series; Level of evidence, 4. Methods: In this 10-year prospective study (2009-2018), robotic-assisted PFA was performed on 44 patients (32 women and 12 men; n = 51 consecutive knees), with a mean age of 37.2 years (range, 21-50 years). The follow-up rate was 98%, with a mean of 5.3 years (range, 2-9.3 years). Primary clinical outcomes were as follows: the validated Cincinnati Knee Rating System sports activity and symptom rating scales, patient psychometric ratings of the substantial clinical benefit (SCB), and the Patient Acceptable Symptom State (PASS). Secondary outcomes were the Cincinnati Knee Rating System occupational rating, visual analog pain scale, and the 12-Item Short Form Health Survey. Survivorship was defined by conversion to total knee replacement (TKR). Results: Before PFA, 78% of patients (35/45 knees) were symptomatic and unable to perform recreational sports, with only 20% of patients (9/45 knees) performing some low-impact sports. After PFA, 80% of patients (36/45 knees) were able to perform low-impact sports, and 7% (3/45 knees) performed jumping-pivoting sports (P < .001). The SCB scored by the patient showed 87% of knees as good, very good, or normal. On the PASS analysis, 89% of patients (95% CI, 76%-96%) were “pleased,” and 93% (95% CI, 82%-99%) would undergo surgery again. There were clinically relevant improvements in symptoms of pain, swelling, and giving way (P = .0001). Preoperatively, 91% of knees had moderate to severe pain with activities of daily living, and only 11% of knees had pain at the follow-up. Five of the 50 knees (10%) underwent TKR conversion with one patient lost to follow-up. Conclusion: PFA resulted in a high return of patients to low-impact sports with high SCB and PASS psychometric ratings. The robotic-assisted 3-dimensional preoperative planning allowed precise intraoperative trochlear implant alignment in knees with severe trochlear dysplasia. PFA is recommended as an alternative treatment in younger patients with end-stage symptomatic patellofemoral arthritis. Registration: NCT02738476 (ClinicalTrials.gov identifier).

Minimum 5-Year Clinical and Return-to-Sport Outcomes After Primary Arthroscopic Scapulothoracic Bursectomy and Partial Scapulectomy for Snapping Scapula Syndrome

Background: Snapping scapula syndrome (SSS) is a rare condition that is oftentimes debilitating. For patients whose symptoms are resistant to nonoperative treatment, arthroscopic surgery may offer relief. Because of the rarity of SSS, reports of clinical outcomes after arthroscopic SSS surgery are primarily limited to small case series and short-term follow-up studies. Purpose: To report minimum 5-year clinical and sport-specific outcomes after arthroscopic bursectomy and partial scapulectomy for SSS and to identify demographic and clinical factors at baseline associated with clinical outcomes at minimum 5-year follow-up. Study Design: Case series; Level of evidence, 4. Methods: Patients who underwent arthroscopic bursectomy and partial scapulectomy for SSS between October 2005 and February 2016 with a minimum of 5 years of postoperative follow-up were enrolled in this single-center study. Clinical outcome scores, including the 12-Item Short Form Health Survey (SF-12), American Shoulder and Elbow Surgeons (ASES) Shoulder Score, shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) score, Single Assessment Numeric Evaluation (SANE), and visual analog scale (VAS) score for pain, were collected at a minimum 5-year follow-up. Additionally, it was determined which patients reached the minimal clinically important difference. Bivariate analysis was used to determine whether baseline demographic and clinical factors had any association with the outcome scores. Results: Of 81 patients eligible for inclusion in the study, follow-up was obtained for 66 patients (age 33.6 ± 13.3 years; 31 female). At a mean follow-up of 8.9 ± 2.5 years (range, 5.0-15.4 years), all of the outcome scores significantly improved compared with baseline. These included the ASES (from 56.7 ± 14.5 at baseline to 87.2 ± 13.9 at follow-up; P < .001), QuickDASH (from 38.7 ± 17.6 to 13.1 ± 14.6; P < .001), SANE (from 52.4 ± 21.2 to 82.7 ± 19.9; P < .001), SF-12 Physical Component Summary (from 39.7 ± 8.3 to 50.3 ± 8.2; P < .001), SF-12 Mental Component Summary (from 48.2 ± 11.7 to 52.0 ± 9.0; P = 0.014) and VAS pain (from 5.2 ± 2.1 to 1.4 ± 2.0; P < .001). The minimal clinically important difference in the ASES score was reached by 77.6% of the patients. Median postoperative satisfaction was 8 out of 10. It was found that 90.5% of the patients returned to sport, with 73.8% of the patients able to return to their preinjury level. At the time of final follow-up, 8 (12.1%) patients had undergone revision surgery for recurrent SSS symptoms. Older age at surgery (P = .044), lower preoperative SF-12 Mental Component Summary score (P = .008), lower preoperative ASES score (P = .019), and increased preoperative VAS pain score (P = .016) were significantly associated with not achieving a Patient Acceptable Symptom State on the ASES score. Conclusion: Patients undergoing arthroscopic bursectomy and partial scapulectomy for SSS experienced clinically significant improvements in functional scores, pain, and quality of life, which were sustained at a minimum of 5 years and a mean follow-up of 8.9 years postoperatively. Higher patient age, inferior mental health status, increased shoulder pain, and lower ASES scores at baseline were significantly associated with worse postoperative outcomes.

Greater changes in self-reported activity level are associated with decreased quality of life in patients following an anterior cruciate ligament reconstruction

ObjectiveTo determine the association between change in physical activity level, as defined as the change from pre-to post-operative Tegner Activity Scale, and quality of life (QOL) after anterior cruciate ligament reconstruction (ACLR), before patients are cleared for return to sport. Participants1198 participants (42.9% male; 18.7 ± 3.6 years; 7.1 ± 3.7 months post-ACLR). Main outcome measuresSurveys included Knee Injury and Osteoarthritis Outcome Score QOL (KOOS-QOL) subscale and Tegner Activity Scale. KOOS-QOL score ≥62.5 is considered as meeting a previously established patient acceptable symptom state. ResultsThe acceptable KOOS-QOL group reported a significantly smaller decrease in activity level from pre-injury to time of data collection (median: 2.00, IQR: 2.00) than the unacceptable KOOS-QOL group (median: 3.00, IQR: 3.00). Across the full cohort, for every one-point larger decrease in Tegner score from pre-to post-ACLR, there is a 52% increase in the odds of having an unacceptable KOOS-QOL score. For adolescents, the odds increase to 60% while the odds for adults were lower at 39%. ConclusionsFollowing ACLR, greater decreases in physical activity level are associated with poorer QOL for both adolescents and adults at short-term follow-up, and this effect is larger amongst adolescents.

Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) Scores > 55 at 6 Months Postoperative Predict Ability to Achieve Patient Acceptable Symptomatic State at Minimum 1 Year Postoperative Following Autologous Chondrocyte Implantation for Grade IV Chondral Defects About the Patellofemoral Joint.

The primary aim is to evaluate the relationship between MOCART scores and patient satisfaction, as evaluated by achievement of (1) the Patient Acceptable Symptomatic State (PASS) and (2) the minimal clinically important difference (MCID) for Knee Injury and Osteoarthritis Score Quality of Life (KOOS QoL), for patients undergoing autologous chondrocyte implantation (ACI) for focal Grade IV patellofemoral chondral defects. The secondary aim is to determine the threshold MOCART score which predicts the ability to meet the PASS and the MCID for KOOS QoL. Patients undergoing ACI for grade IV patellofemoral chondral defects by a single surgeon from 2017 to 2020 were identified by search of the EMR. To determine PASS status, patients were asked, "Do you consider your current level of symptoms to be acceptable?" KOOS QoL scores were also collected. Patients with 6-month postoperative knee MRI, PASS scores, and minimum 2-year follow-up data were included. Paired t tests and Wilcoxon Rank-Sum tests were used to evaluate the relationship between MOCART scores and (1) PASS achievement and (2) achievement of the MCID for KOOS QoL (12.8). Thirty-four patients were included, with a median age of 35.1 years [IQR: 24.6, 37.1], and BMI of 24.0 kg/m2 [IQR: 21.5, 28.1]. The median time to postoperative MRI was 6.7 months [IQR: 5.8, 7.9], and average follow-up time was 3.7 ± 1.2 years. Twenty-five patients (74%) achieved PASS, and 18 patients (out of 27 who had postop KOOS QoL Scores, 67%) achieved the MCID for KOOS QoL. Patients who achieved PASS had higher average MOCART scores (61.8 ± 16.0) than those who did not achieve PASS (45.0 ± 12.8, p=0.011), whereas patients who achieved the MCID for KOOS QoL did not have higher MOCART scores than those who did not achieve the MCID (61.9 ± 18.3 versus 53.3 ± 17.1, P = 0.25). There was no relationship between age, sex, lesion size, and lesion location and ability to achieve PASS or MCID for KOOS QoL (p>0.05). A threshold MOCART value of 55 was associated with the highest AUC on ROC analysis for likelihood of achieving PASS (0.778) and MCID for KOOS QoL (0.667). Higher MOCART scores are associated with an increased likelihood of achieving PASS following patellofemoral ACI. Moreover, MOCART scores > 55 predict the ability to achieve PASS and the MCID for KOOS QoL following patellofemoral ACI. IV.

Clinical Significance Thresholds in Primary and Revision Latarjet Procedures With Comparable Outcome Achievements

Background: Given the variability across populations and settings, defining the MCID and the PASS for the Rowe and ASOSS scores and patients undergoing primary and revision Latarjet it is essential to have accurate benchmarks relevant to these groups when interpreting clinical results. Purpose: To determine the minimal clinically important difference (MCID) and Patient Acceptable Symptom State (PASS) thresholds for the visual analog scale (VAS) for pain during sports, Athletic Shoulder Outcome Scoring System (ASOSS), and Rowe scores after primary and revision Latarjet procedures for treatment of shoulder instability. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: Between January 2018 and January 2020, a retrospective review of 149 patients undergoing primary Latarjet (n = 82) and revision Latarjet (n = 67) to treat shoulder instability was performed in a single institution. Patient-reported outcome measures were collected preoperatively and 1 year postoperatively. The delta was defined as the change between the pre- and postoperative scores. Distribution-based and anchored-based approaches were used to estimate the MCID and the PASS, respectively. The optimal cutoff point and the percentage of patients achieving those thresholds were also calculated. Results: The distribution-based MCIDs after primary Latarjet were 1.1, 7.5, and 9.6 for the VAS, Rowe, and ASOSS scores, respectively. The rates of patients who achieved the MCID thresholds were 93.9%, 98.7%, and 100% for the VAS, Rowe, and ASOSS scores, respectively. The PASS thresholds after primary Latarjet were ≤1, ≥90, and ≥85 for the VAS, Rowe, and ASOSS scores, respectively. The percentages of patients who achieved PASS thresholds were 82.9%, 89%, and 86.5% for the VAS, Rowe, and ASOSS scores, respectively. The distribution-based MCIDs after revision Latarjet were 0.6, 6.2, and 3.4 for the VAS, Rowe, and ASOSS scores, respectively. The rates of patients who achieved MCID thresholds were 89.3%, 100%, and 100% for the VAS, Rowe, and ASOSS scores, respectively. The PASS thresholds were ≤3, ≥87, and ≥86 after revision Latarjet for the VAS, Rowe, and ASOSS scores, respectively. The rates of patients who achieved the PASS thresholds were 88%, 88%, and 91% for the VAS, Rowe, and ASOSS, respectively. Conclusion: This study identified useful values for the MCID and PASS thresholds in VAS, Rowe, and ASOSS scores after primary and revision Latarjet procedures for treating shoulder instability. Most patients achieved MCID and PASS benchmarks, indicating successful primary and revision Latarjet procedure outcomes. These metrics can serve as valuable parameters when analyzing parameters in future studies and have the potential to enhance patient care by optimizing treatment strategies and surgical decision making.

Clinical outcomes after hip arthroscopy in acetabular dysplastic patients, previously treated with periacetabular osteotomy: a minimum of two-year follow-up data from the Danish Hip Arthroscopy Registry

ABSTRACT Periacetabular osteotomy (PAO) is the treatment of choice in dysplastic acetabulum. Due to continued symptoms, 2–11% of these patients require an additional hip arthroscopy. The purpose of this study was to report clinical outcome after a minimum of 2-year follow-up of additional hip arthroscopy after PAO with data from Danish Hip Arthroscopy Registry. Inclusion criteria in the study cohort were PAO surgery resulting in an additional hip arthroscopy procedure. The cohort was evaluated according to the surgical findings and patient-related outcome measures (PROMs) pre-operatively and at 2-year follow-up. A total of 287 patients were included in the study cohort. PROMs improved significantly in all subscales from pre-operatively to 2-year follow-up in the study cohort. According to PROM subscales, 47.8–57.6% and 25.2–38.2% achieved Minimal Clinical Important Difference and Patient Acceptable Symptom State, respectively. This study demonstrates, in PAO-treated patients, significant PROM improvements after additional hip arthroscopy. Unfortunately, only ∼50% and 30% achieved Minimal Clinical Important Difference and Patient Acceptable Symptom State, respectively.

Outcomes of Flexibility Sport Athletes With Borderline Hip Dysplasia After Hip Arthroscopy for Femoroacetabular Impingement Syndrome: A Propensity-Matched Analysis at Minimum 2-Year Follow-up

Background: Hip arthroscopy has proved successful in treating femoroacetabular impingement syndrome (FAIS) in patients with and without borderline hip dysplasia (BHD). Despite a high prevalence of BHD in patients who participate in sports with high flexibility requirements, a paucity of literature evaluates the efficacy of hip arthroscopy in treating FAIS in flexibility sport athletes with BHD. Purpose: To compare minimum 2-year patient-reported outcomes (PROs) and achievement of clinically significant outcomes in flexibility sport athletes with BHD undergoing primary hip arthroscopy for FAIS with capsular plication with results in flexibility sport athletes without dysplasia. Study Design: Cohort study; Level of evidence, 3. Methods: Data were prospectively collected for patients undergoing primary hip arthroscopy for FAIS with BHD, defined as a lateral center-edge angle of 18° to 25°, who reported participation in a sport with a high flexibility requirement, including dance, gymnastics, figure skating, yoga, cheerleading, and martial arts, according to previous literature. These patients were matched 1:2 to flexibility sport athletes without dysplasia, controlling for age, sex, and body mass index. Preoperative and minimum 2-year postoperative PROs were collected and compared between groups. Cohort-specific minimal clinically important difference and patient acceptable symptom state achievement was compared between groups. Results: In total, 52 flexibility sport athletes with BHD were matched to 104 flexibility sport athletes without BHD. Both groups showed similar sport participation (P = .874) and a similar level of competition (P = .877). Preoperative lateral center-edge angle (22.2°± 1.6° vs 31.5°± 3.9°; P < .001) and Tönnis angle (10.9°± 3.7° vs 5.8°± 4.4°; P < .001) differed between groups. Capsular plication was performed in all cases. Both groups achieved significant improvement in all PROs (P < .001) with no differences in postoperative PROs between groups (P≥ .147). High minimal clinically important difference (BHD group: 95.7%; control group: 94.8%) and patient acceptable symptom state (BHD group: 71.7%; control group: 72.2%) achievement for any PRO was observed with no differences between groups (P≥ .835). Conclusion: Flexibility sport athletes with BHD achieved similar outcomes as those of flexibility sport athletes without BHD after hip arthroscopy for FAIS with capsular plication.

Comparison of Pain Scores and Functional Outcomes of Patients Undergoing Arthroscopic Hip Labral Repair and Concomitant Capsular Repair or Plication Versus No Closure.

The need for capsular closure during arthroscopic hip labral repair is debated. To compare pain and functional outcomes in patients undergoing arthroscopic hip labral repair with concomitant repair or plication of the capsule versus no closure. Cohort study. Outcomes were compared between patients undergoing arthroscopic hip labral repair with concomitant repair or plication of the capsule versus no closure at up to 2 years postoperatively and with stratification by age and sex. Patients with lateral center-edge angle <20°, a history of instability, a history of prior arthroscopic surgery in the ipsilateral hip, or a history of labral debridement only were excluded. Subanalysis was performed between patients undergoing no capsular closure who were propensity score matched 1:1 with patients undergoing repair or plication based on age, sex, and preoperative Modified Harris Hip Score (MHHS). We compared patients who underwent T-capsulotomy with concomitant capsular closure matched 1:5 with patients who underwent an interportal capsulotomy with concomitant capsular repair based on age, sex, and preoperative MHHS. Patients undergoing capsular closure (n = 1069), compared with the no-closure group (n = 230), were more often female (68.6% vs 53.0%, respectively; P < .001), were younger (36.4 ± 13.3 vs 47.9 ± 14.7 years; P < .001), and had superior MHHS scores at 2 years postoperatively (85.8 ± 14.5 vs 81.8 ± 18.4, respectively; P = .020). In the matched analysis, no difference was found in outcome measures between patients in the capsular closure group (n = 215) and the no-closure group (n = 215) at any follow-up timepoint. No significant difference was seen between the 2 closure techniques at any follow-up timepoint. Patients with closure of the capsule achieved the minimal clinically important difference (MCID) and the patient acceptable symptom state (PASS) for the 1-year MHHS at a similar rate as those without closure (MCID, 50.3% vs 44.9%, P = .288; PASS, 56.8% vs 51.1%, P = .287, respectively). Patients with T-capsulotomy achieved the MCID and the PASS for the 1-year MHHS at a similar rate compared with those with interportal capsulotomy (MCID, 50.1% vs 44.9%, P = .531; PASS, 65.7% vs 61.2%, P = .518, respectively). When sex, age, and preoperative MHHS were controlled, capsular closure and no capsular closure after arthroscopic hip labral repair were associated with similar pain and functional outcomes for patients up to 2 years postoperatively.

Hip Arthroscopy Patients With Lower Back Pain Show Delayed Clinical Improvement and Inferior Time-Dependent Survivorship: A Propensity Matched Study at Mid-Term Follow-Up

PurposeTo evaluate patient-reported outcomes (PROs) and survivorship at mid-term follow-up after hip arthroscopy (HA) for femoroacetabular impingement syndrome (FAIS) in patients with and without preoperative lower back pain (LBP). MethodsPatients with self-endorsed preoperative LBP who underwent HA for FAIS with mid-term follow-up were identified and propensity matched 1:1 to patients without back pain by age, sex, and body mass index. PROs collected preoperatively and at postoperative years 1, 2, and 5 included: Hip Outcome Score Activities of Daily Living (HOS-ADL) and Sports Subscale (HOS-SS), International Hip Outcome Score 12 (iHOT-12), modified Harris Hip Score (mHHS), Visual Analog Scale (VAS) for Pain. Achievement of minimal clinically important difference (MCID) and patient acceptable symptom state (PASS) were compared. Survivorship was compared with Kaplan-Meier analysis. Results119 patients with LBP were matched to 119 patients without LBP. Group demographic factors were as follows, age (37.4±11.9 years vs 37.6±12.6, p=0.880), sex (64.4% female vs 67.7%, p=0.796), and BMI (25.3±5.1 kg/m2 vs 25.3±5.4, p=0.930). Average follow-up duration was 6.0 ± 1.9 years. LBP patients showed similar preoperative PROs, yet lower 1-year scores for all PROs (p ≤ 0.044). At final follow-up, similar PROs were shown between groups (p ≥ 0.196). LBP and non-LBP patients had similar MCID achievement for HOS-ADL (59.3%vs.63.1%,p=0.640), HOS-SS (73.9%vs.70.8%,p=0.710), mHHS (66.7%vs.73.4%, p=-.544), iHOT-12 (85.1%vs.79.4%,p=0.500), and VAS-Pain (75.6%vs.69.9%,p=0.490). Groups also had similar PASS achievement for HOS-ADL (63.5%vs.61.3%,p=0.777), HOS-SS (57.0%vs.62.5%,p=0.461), mHHS (81.9%vs.79.1%, p=0.692), iHOT-12 (54.6%vs.61.2%,p=0.570), and VAS-Pain (51.0%vs.55.4%,p=0.570).with similar MCID (p ≥ 0.490) and PASS (p ≥ 0.386) achievement. Conversion to total hip arthroplasty occurred in 3.4% of hips with LBP and 0.8% of hips without LBP (p=0.370), Back pain patients demonstrated inferior time-dependent survivorship compared to patients without back pain on Kaplan-Meier survival analysis (p = 0.023). ConclusionsPatients undergoing primary hip arthroscopy for femoroacetabular impingement syndrome with LBP achieve comparable PROs and CSOs to patients without back pain at mid-term, despite lower 1-year PRO scores. LBP patients show inferior reoperation-free time-dependent survivorship compared to those without LBP.

Six-Month Outcomes Correlate With 10-Year Outcomes After Hip Arthroscopy for Femoroacetabular Impingement Syndrome

To identify whether 6-month outcomes after hip arthroscopy for femoroacetabular impingement syndrome (FAIS) correlate with outcomes at minimum 10-year follow-up. Patients who underwent primary hip arthroscopy for FAIS from 2012 to 2013 were reviewed and included if they had 6-month and minimum 10-year follow-up. Patient-reported outcome (PRO) measures included the Hip Outcome Score Activities of Daily Living (HOS-ADL) subscale, Hip Outcome Score Sports-Specific (HOS-SS) subscale, modified Harris Hip Score (mHHS), visual analog scale (VAS) for pain, and VAS for satisfaction. We compared 6-month and 10-year outcome scores and analyzed the relations between 6-month and 1-, 2-, 5-, and 10-year outcome scores using Pearson correlation coefficients (r). Six-month scores and clinically significant outcome achievement were then compared with 10-year clinically significant outcome achievement and reoperations, including revision hip arthroscopy and conversion to total hip arthroplasty (THA), using logistic regressions and the Fisher exact test. This study included 60 patients (60.0% female sex; mean age, 36.0 ± 12.2 years). The mHHS, VAS pain score, and VAS satisfaction score significantly improved from 6-month to 10-year follow-up (P ≤ .021), whereas the HOS-ADL and HOS-SS did not (P ≥ .072). There were significant correlations between 6-month and 10-year scores for the HOS-ADL (r= 0.505), HOS-SS (r= 0.592), and mHHS (r= 0.362) (P ≤ .022 for all), as well as significant correlations between 6-month and 1-, 2-, and 5-year scores (P ≤ .014 for all). The 6-month HOS-ADL, HOS-SS, and mHHS were all significantly associated with their respective 10-year achievement of the patient acceptable symptom state (PASS) (P ≤ .044). Furthermore, 6-month HOS-ADL and mHHS were significantly associated with THA conversion (P ≤ .041). Comparable 6-month and 10-year achievement of the minimal clinically important difference (96.5% vs 97.8%, P > .999) and PASS (85.2% vs 87.5%, P > .999) for any PRO was observed. After hip arthroscopy for FAIS, patients' 6-month HOS-ADL and mHHS were significantly associated with their 10-year PROs, PASS achievement, and THA conversion, although correlation strengths decreased with increasing time from surgery. Level IV, case series.

Defining the Patient Acceptable Symptom State (PASS) for PROMIS After Hallux Rigidus Correction Surgery

Introduction/Purpose: In an ever-changing healthcare landscape, patient-reported outcomes (PROs) are becoming more important for reimbursement and evaluating the success of surgical procedures. Unfortunately, it is unclear which PROs correlate best with clinical improvement. The patient acceptable symptom state (PASS) asks the patient whether or not their outcome is acceptable at a particular post-operative time point. Recently, the use of this metric has gained traction within the foot and ankle literature. To our knowledge, this is the first study that aims to establish PASS thresholds for Patient-Reported Outcome Measurement Information System (PROMIS) scores in patients who underwent operative intervention for hallux rigidus. Methods: A retrospective review of prospectively collected data within an institutional registry was performed. We identified 174 patients treated for hallux rigidus between February 2019 and March 2021 with at least 2-year post-operative PROMIS scores. Chart review was performed to obtain demographic information and to confirm the surgical procedures that were completed. Two-years post-operatively, patients answered two PASS anchor questions (Satisfaction, Delighted-Terrible scale) with Likert- scale responses, which was collected along with pre-operative and 2-year post-operative PROMIS scores via the registry. After patient’s answers to the Satisfaction and Delighted-Terrible scales were recategorized into binary responses, PASS thresholds were determined using the maximum Youden Index and a 95% confidence interval was quantified using 2000 bootstrapped iterations. Differences in patient and surgical characteristics between patients who met or did not meet the PASS threshold were compared using independent samples t-test and Pearson chi square. Statistical significance was established at an alpha of 0.05. Results: There was excellent association between PASS thresholds and the PROMIS domains of Physical Function (48.6, AUC=0.82) and Pain Interference (52.1, AUC =0.86). Overall, 125/174 (71.8%) and 105/174 (60.3%) patients met the threshold for Physical Function (PF) and Pain Interference (PI), respectively. For the PF and PI domains, age, BMI, method of cheilectomy and use of Akin/Moberg osteotomy did not impact a patient’s likelihood of meeting the PASS threshold. For the PF domain and the PI domain stratified by the Delighted-Terrible scale, women were more likely to meet the PASS threshold than men (63.2% vs. 36.8%, p = 0.057 and 73% vs. 45%, p =0.023, respectively). Lastly, patients with a higher pre-operative PF score had a higher chance of meeting the PASS threshold (p &lt; 0.001). Conclusion: Following operative intervention to treat hallux rigidus, pre-operative PROMIS scores were strongly associated with a patient’s likelihood of meeting the PASS threshold. After surgical intervention for hallux rigidus, less than 75% of the patients felt their outcome was acceptable; however, the PASS threshold for PF was lower than population average, so it may not be necessary for patients to reach normal physical function levels post-operatively in order to have an acceptable outcome.

Defining the Patient Acceptable Symptom State Using PROMIS Following Reconstruction of the Progressive Collapsing Foot Deformity

Introduction/Purpose: Although reconstruction of the flexible progressive collapsing foot deformity (PCFD) has been shown to improve patient-reported outcomes (PROs), there is limited data describing postoperative success as defined by patient satisfaction following surgery. Distinct from the minimal clinically important difference (MCID), the patient acceptable symptom state (PASS) is a novel PRO measurement that represents the symptom threshold beyond which patients are satisfied with their postoperative outcome. The primary aim of this study was to use Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF) and Pain Interference (PI) scores in combination with anchor questions to define PASS thresholds following reconstruction of the flexible PCFD. A secondary aim was to analyze how patient-specific variables and certain PCFD reconstruction procedures may impact the probability of reaching PASS thresholds. Methods: Using data collected from a foot and ankle orthopedic registry at a large academic institution, 109 patients who underwent reconstruction of a flexible PCFD between February 2019 and March 2021, had preoperative and 2-year postoperative PROMIS PF and PI scores, and 2-year postoperative responses to two PASS anchor questions (the delighted-terrible scale and the satisfied scale) were included in the study. Patients who underwent either a double or triple arthrodesis were excluded. Patient responses to the anchor questions were dichotomized and receiver operating characteristic (ROC) curve analyses were performed. Using the Youden Index to balance sensitivity and specificity and maximize the area under the curve (AUC), PASS thresholds with 95% confidence intervals were quantified using 2000 bootstrapped iterations. Lastly, multivariable logistic regressions were performed to analyze the influence of patient demographics, preoperative PROMIS scores, and certain PCFD reconstruction procedures on the probability of reaching the PASS thresholds. Results: The PASS threshold for PROMIS PF was found to be 42.6 using both the delighted-terrible and the satisfied scale and 73.4% of patients (80/109) reached the threshold (both AUCs: 0.91) (Table 1). The PASS thresholds for PROMIS PI defined using the delighted-terrible scale and the satisfied scale were 54.5 (AUC: 0.90) and 57.5 (AUC: 0.91), respectively, with 72.5% of patients (79/109) and 81.7% of patients (89/109) meeting the respective thresholds. Neither patient demographics nor specific PCFD reconstruction procedures affected the probability of meeting the PASS thresholds. However, a lower preoperative PROMIS PF score or a higher preoperative PROMIS PI score significantly decreased the probability of achieving the PASS thresholds. Conclusion: Following reconstruction of the flexible PCFD, PASS thresholds for the PROMIS PF and PI domains were found to be lower and higher, respectively, than population norms. This suggests that patients may be satisfied with the outcome of their surgery despite not returning to the population mean. The probability of achieving the PASS thresholds was influenced by both preoperative PROMIS PF and PI scores but not by patient demographics or certain PCFD reconstruction procedures. In addition to guiding future outcomes research, these results may help foot and ankle surgeons optimize treatment for the flexible PCFD and better manage patient expectations.

Defining the Patient Acceptable Symptom State (PASS) for PROMIS After Hallux Valgus Correction Surgery

Introduction/Purpose: Surgical interventions to correct hallux valgus have been shown to improve patient reported outcomes (PROs); however, many of these instruments do not measure a patient’s subjective outcome experience. The patient acceptable symptom state (PASS) is defined as the symptom threshold that a patient must reach to be satisfied with the outcome of their surgery. PASS thresholds have been defined for hallux valgus correction using American Orthopaedic Foot &amp; Ankle Society (AOFAS) scores; however, no studies have used a validated PRO metric. This is the first study that aims to establish PASS thresholds for Patient-Reported Outcome Measurement Information System (PROMIS) scores in patients following operative intervention for hallux valgus. Methods: A retrospective review of prospectively collected data within an institutional registry was performed. We identified 291 patients treated for hallux valgus with or without second hammertoe correction between February 2019 and March 2021 with at least 2-year post-operative PROMIS scores. Chart review was performed to obtain demographic information and to confirm the surgical procedures completed. Two-years post-operatively, patients answered two PASS anchor questions (Satisfaction, Delighted-Terrible scale) with Likert-scale responses, which was collected along with pre-operative and 2-year post-operative PROMIS scores via the registry. After patient’s answers to the Satisfaction and Delighted-Terrible scales were recategorized into binary responses; PASS thresholds were determined using the maximum Youden Index and a 95% confidence interval was quantified using 2000 bootstrapped iterations. Differences in patient and surgical characteristics between patients who met or did not meet the PASS threshold were compared using independent samples t-test and Pearson chi square. Results: There was excellent association between PASS thresholds and the PROMIS domains of Physical Function (50.3, AUC=0.86) and Pain Interference (51.5, AUC=0.86). Overall, 204/291 and 205/291 patients met the threshold for Physical Function (PF) and Pain Interference (PI), respectively. For both PROMIS domains, a lower BMI was associated with a higher likelihood of meeting the PASS threshold (p=0.002 for PF, p=0.032 for PI). For the PF domain, Lapidus patients were more likely to meet the PASS threshold (p=0.05), and patients with first MTP fusion were less likely to meet the PASS threshold (p=0.004). Meeting the PASS threshold wasn’t impacted by the concomitant correction of a second hammertoe. Lastly, patients with a higher pre-operative PF score had a greater chance of meeting the PASS threshold (p &lt; 0.001). Conclusion: This is the first study to define a PASS threshold for hallux valgus correction using PROMIS scores, a validated outcomes measure. Pre-operative PROMIS scores, patient BMI, and the type of procedure performed impacted a patient’s likelihood of meeting the PASS threshold. These results may be helpful in counseling and educating patients on their chances of obtaining a satisfactory result following hallux valgus correction.

Construct validity, reliability, and threshold value for treatment goals of the Thai version of the 12-item Psoriatic Arthritis Impact of Disease Questionnaire for patients with psoriatic arthritis.

To determine the construct validity, reliability, and treatment goal threshold of a Thai-language version of the 12-item Psoriatic Arthritis Impact of Disease (Thai-PsAID) questionnaire in patients with psoriatic arthritis (PsA). This cross-sectional study involved administering the proposed Thai-PsAID to 117 Thai patients with PsA. Reliability was assessed by Cronbach's α test and intraclass correlation coefficient (ICC). Construct validity was assessed using Spearman correlation with clinical disease activity index for psoriatic arthritis (cDAPSA), the Health Assessment Questionnaire (HAQ), EQ-5D index, and the patient-acceptable symptom state (PASS). The optimal cutoff score of the Thai-PsAID for minimal disease activity (MDA) was determined by receiver operating characteristic curves. Participants had a mean age of 49.5 years, 61 (52.1%) were female, and the median disease duration was 5 years. The median Thai-PsAID score was 2.1, with a Cronbach's α coefficient of .95 and an ICC of 0.77. The mean time to complete the Thai-PsAID was 2.1 min, with no missing data. The Thai-PsAID score demonstrated a moderate correlation with the cDAPSA, HAQ, and EQ-5D with indices (Spearman's rho of .64, .54, and -.55, respectively). The cutoff of 2.7 has 81%-84% sensitivity and 69%-85% specificity for classifying patients with MDA, satisfied PASS, and indicating no need to escalate medication. The Thai-PsAID is a valid, reliable, and feasible tool for measuring PsA prognosis. A cutoff of 2.7 accurately discriminates MDA and PASS and indicates no need for medication escalation. The Thai-PsAID may be used as a standalone measure.

Worse Patient-Reported Outcomes and Spino-Pelvic Parameters After Total Hip Arthroplasty for Rapidly Progressive Osteoarthritis of the Hip Compared to Osteoarthritis: A Propensity-Matched Cohort Study

BackgroundThis study aimed to assess the association between the disease process of hip osteoarthritis and total hip arthroplasty (THA) outcomes; this is a critical issue, as rapid progression has been postulated to be responsible for patient dissatisfaction after THA. MethodsThis retrospective case-control study included 255 patients who underwent THA and completed a mean follow-up duration of 42.1 months (range, 24.0 to 77.0). We classified patients into those who had (n = 26) and did not have (n = 229) rapidly progressive osteoarthritis of the hip (RPOA), defined as a narrowing rate of joint space ≥ 2 mm yearly or a ≥ 50% loss within 12 months, excluding any other cause of a destructive arthropathy. Propensity score-matched cohorts for age, sex, body mass index, and spino-pelvic measures were created, and the outcomes were compared between the 2 groups. ResultsAfter successfully matching RPOA (n = 25) and non-RPOA patients (n = 50), there were significant differences in minimum clinically important difference (P = .009 for European Quality of Life 5-Dimension, and P < .001 for low back pain), patient acceptable symptom state (P = .015 for European Quality of Life 5-Dimension, and P < .001 for Hip Disability and Osteoarthritis Outcome Score Joint Replacement score), patient satisfaction (P = .028), and T1 pelvic angle as an indicator of global sagittal spinal deformity (P = .017). There was a correlation between T1 pelvic angle and low back pain in the RPOA group (R = 0.628, P < .001). ConclusionsPatients who exhibited RPOA before undergoing THA showed worse patient-reported outcomes compared with those who did not have rapid progression. Our study highlights the critical role of the disease process in influencing THA outcomes, advocating for a paradigm shift toward more meticulous preoperative evaluations, including global spinal deformity, standardized diagnostic criteria, and tailored interventions.

Patients Undergoing Postless Hip Arthroscopy Demonstrate Significantly Better Patient-Reported Outcomes and Clinically Significant Outcomes Compared to Conventional Post-Assisted Hip Arthroscopy at Short-Term Follow-Up

PurposeTo prospectively compare the short-term clinical outcomes of patients undergoing hip arthroscopy with versus without the use of a perineal post. MethodsA prospective, single-surgeon cohort study was performed on a subset of patients undergoing hip arthroscopy between 2020 and 2022. A post-free hip distraction system was used at one center at which the senior author operates, and a perineal post was used at another surgical location. An electronic survey of Patient-Reported Outcome Measures (PROMs) was completed by each patient at a minimum of 1 year postoperatively. PROMs included a Visual Analogue Scale (VAS) for pain, University of California Los Angeles (UCLA) Activity Scale, modified Harris Hip Score (mHHS), Hip Outcome Score-Sports-Specific Subscale (HOS-SSS), and a Single Assessment Numeric Evaluation (SANE). Postoperative scores and clinically significant outcomes including the minimal clinically important difference (MCID), substantial clinical benefit (SCB), and patient acceptable symptom state (PASS) for each PROM were compared between groups. ResultsSixty-nine patients were reached for follow-up (41 post, 28 postless) of 87 patients eligible for the study (79%). No significant differences were found between groups in terms of sex (post: 61% female, postless: 54% female, p = 0.54), age (post: 34 years, postless: 29 years, p = 0.11), body mass index (post: 26 kg/m2, postless: 24 kg/m2, p = 0.23) or follow-up duration (post: 24.4 months, postless: 21.3 months, p = 0.16). There was a significantly higher VAS (3.1 vs 1.4, p = 0.01), significantly lower UCLA Activity Score (7.0 vs 8.4, p = 0.02), and significantly lower mHHS (73.7 vs. 82.2, p = 0.03) in the post-assisted group. A significantly higher proportion of patients in the postless group achieved a PASS for the UCLA (89.3% vs. 68.3%, p = 0.04), mHHS (84.6% vs. 61.0%, p = 0.04), and HOS-SSS (84.0% vs. 61.0%, p = 0.048), and a SCB for HOS-SSS (72.0% vs. 41.5%, p = 0.02). One patient (2.6%) in the post group underwent revision hip arthroscopy and another was indicated for total hip arthroplasty by the time of follow-up. ConclusionPostless hip arthroscopy may result in better clinical outcomes compared to post-assisted hip arthroscopy. Level of EvidenceIII, retrospective cohort study

Quadriceps Tendon Autograft ACL Reconstruction With Suture Tape Augmentation: Safe Results Based on Minimum 2-Year Follow-up MRI.

The potential intra-articular effects of ≥1 year after anterior cruciate ligament reconstruction (ACLR) with independent suture tape augmentation (STA) are not fully understood. To investigate whether incorporating suture tape in an all-soft tissue quadriceps tendon autograft (QTA) ACLR leads to satisfactory patient outcomes while having no intra-articular side effects as determined by magnetic resonance imaging (MRI). Case series; Level of evidence, 4. Included were 25 patients with a mean age of 19.9 years (95% CI, 17.3-22.5 years) who underwent QTA ACLR with STA between 2016 and 2019. All patients underwent MRI at ≥1 year postoperatively and had at least a 2-year follow-up (mean, 28 months [95% CI, 26.5-29.5 months]) that included physical examination with anterior laxity testing with KT-1000 arthrometer, radiographs, and patient-reported outcome measures (PROMs). At the final follow-up, the minimal clinically important difference (MCID) and the Patient Acceptable Symptom State (PASS) for applicable PROMs were applied to each patient. Postoperative graft and joint integrity were assessed using the Howell classification and the MRI Osteoarthritis Knee Score (MOAKS) joint effusion/synovitis grade. The Mann-Whitney U test for continuous variables and the chi-square or the Fisher exact test for categorical variables were used for statistical analyses. The MRI assessment of the grafts demonstrated intact grafts in all patients. Overall, 96% of patients demonstrated grades 0 or 1 MOAKS for joint effusion/synovitis. All patient outcomes significantly improved from preoperatively to the final follow-up (P < .001), except for the Marx score, which decreased significantly (14.2 [95% CI, 12.7-15.8] vs 9.72 [95% CI, 7.3-12.2]; P = .0014). At least 68% of the patients achieved the MCID threshold, and 92% achieved the PASS threshold for all applicable PROMs. QTA ACLR with STA did not demonstrate adverse intra-articular changes on MRI at ≥1 year postoperatively. In addition, STA did not appear to negatively affect PROMs.

Surgeon Performance as a Predictor for Patient-Reported Outcomes After Arthroscopic Partial Meniscectomy.

Surgeon performance has been investigated as a factor affecting patient outcomes after orthopaedic procedures to improve transparency between patients and providers. The purpose of this study was to identify whether surgeon performance influenced patient-reported outcomes (PROMs) 1 year after arthroscopic partial meniscectomy (APM). It was hypothesized that there would be no significant difference in PROMs between patients who underwent APM from various surgeons. Case-control study; Level of evidence, 3. A prospective cohort of 794 patients who underwent APM between 2018 and 2019 were included in the analysis. A total of 34 surgeons from a large multicenter health care center were included. Three multivariable models were built to determine whether the surgeon-among demographic and meniscal pathology factors-was a significant variable for predicting the Knee injury and Osteoarthritis Outcome Score (KOOS)-Pain subscale, the Patient Acceptable Symptom State (PASS), and a 10-point improvement in the KOOS-Pain at 1 year after APM. Likelihood ratio (LR) tests were used to determine the significance of the surgeon variable in the models. The 794 patients were identified from the multicenter hospital system. The baseline KOOS-Pain score was a significant predictor of outcome in the 1-year KOOS-Pain model (odds ratio [OR], 2.1 [95% CI, 1.77-2.48]; P < .001), the KOOS-Pain 10-point improvement model (OR, 0.57 [95% CI, 0.44-0.73), and the 1-year PASS model (OR, 1.42 [95% CI, 1.15-1.76]; P = .002) among articular cartilage pathology (bipolar medial cartilage) and patient-factor variables, including body mass index, Veterans RAND 12-Item Health Survey-Mental Component Score, and Area Deprivation Index. The individual surgeon significantly impacted outcomes in the 1-year KOOS-Pain mixed model in the LR test (P = .004). Patient factors and characteristics are better predictors for patient outcomes 1 year after APM than surgeon characteristics, specifically baseline KOOS-Pain, although an individual surgeon influenced the 1-Year KOOS-Pain mixed model in the LR test. This finding has key clinical implications; surgeons who wish to improve patient outcomes after APM should focus on improving patient selection rather than improving the surgical technique. Future research is needed to determine whether surgeon variability has an impact on longer-term patient outcomes.

Defining the patient acceptable symptom state using PROMIS following reconstruction of the progressive collapsing foot deformity

BackgroundThe patient acceptable symptom state (PASS) represents the threshold beyond which patients are satisfied with their outcome. This study aimed to define PASS thresholds for progressive collapsing foot deformity (PCFD) reconstruction using Patient-Reported Outcomes Measurement Information System (PROMIS) scores and anchor question responses. MethodsThis retrospective study consisted of 109 patients who underwent flexible PCFD reconstruction, had preoperative and 2-year postoperative PROMIS scores, and 2-year postoperative anchor question responses. ROC curve analyses were performed to quantify PASS thresholds. ResultsPASS thresholds for the PROMIS Physical Function (PF) and Pain Interference (PI) domains were found to be lower and higher, respectively, than population norms. Furthermore, patients with higher preoperative PROMIS PF scores or lower preoperative PROMIS PI scores had a significantly higher likelihood of achieving the PASS thresholds. ConclusionIn addition to guiding future outcomes research, these results may help surgeons optimize treatment for PCFD and better manage patient expectations.

Arthroscopic rotator cuff repair in active patients younger than 45 Years: a prospective analysis with a mean 5-year follow-up

PurposeTo report clinical and activity specific outcomes after arthroscopic RCR(ARCR) for full-thickness supraspinatus tears in active individuals younger than or equal to 45 years of age. The pre hoc hypothesis was that patients in this age group would demonstrate significant improvements in clinical outcomes following ARCR along with a significant improvement of athletic abilities. MethodsPatients were included in this study if they were (1)active individuals between 18 and 45 years of age at the time of surgery, (2)had a full-thickness rotator cuff tear(RCT) of the supraspinatus tendon with or without anterior or posterior extension and (3)underwent ARCR. Pre- and postoperative patient-reported outcomes scores including the American Shoulder and Elbow Surgeons(ASES) score, Disabilities of Arm, Shoulder and Hand(Quick-DASH), Single Assessment Numeric Evaluation(SANE), Short Form-12 Physical Component Summary(SF-12PCS) were prospectively collected and postoperative patient satisfaction(scale of 1-10) was recorded at a minimum of 2 years postoperatively. Attainment of the minimal clinically important difference(MCID) and patient acceptable symptom state(PASS) for the ASES was calculated. Athletic activity specific outcomes and return to activity(RTA) were investigated prospectively via a custom-made comprehensive questionnaire. ResultsBetween 11/2005 and 6/2020, of 1149 RCRs performed by the senior author, 54 patients (mean age 40.9 years,13 female; follow-up 69.7 ± 35.2 months in a range of 24.6 – 179.6 months) were included into the outcomes analysis. Of those, 4 patients(7.4%) had progressed to revision rotator cuff repair. At a follow-up of 5.8 years, outcome scores had significantly improved compared to preoperative baselines (ASES55.6±13.8to90.1+15.8;p<.001;QuickDASH38.9±18.4to 11.9±17.1;p<.001, SANE60.7±22.7to79.3±27.6;p=.001, SF-12PCS41.6±8.3to51.9±9.0;p<=.001). 93.6% of the patients reached the MCID and 72.6% reached the PASS. Median satisfaction was 9.5/10. 86% of the patients returned to sports, while 67% of the patients returned to a similar level compared to preoperatively. All sport specific metrics such as shoulder strength and endurance(p<.001), intensity(p<.001), and impairments from pain affecting speed(p=0.002), endurance(p=.002) and competition(p<.001) significantly improved postoperatively. ConclusionARCR of full-thickness RCT in active individuals aged 45 or younger results in a clinically relevant improvement of outcomes, function and quality of life at a minimum of 2 years and mean 5.8-year follow-up with a low rate of revision. While 86% of patients were able to RTA and sport specific outcome metrics significantly and substantially improved compared to preoperatively, a return to preinjury levels was not reliably achieved in all patients, with particular limitations observed in overhead active individuals. The data support the hypothesis that patients in this age group demonstrate significant improvements in clinical outcomes following ARCR along with significant improvements in athletic abilities.
