Outcomes of Traditional Dual Growing Rods With Apical Control Techniques for the Treatment of Early-Onset Scoliosis: Comparison With Patients Treated With Traditional Dual Growing Rods Only With a Minimum 2-Year Follow-up After Graduation.

Correction with traditional dual growing rods (TDGR) might not be sufficient for severe and rigid spinal deformity. TDGR combines with apical control techniques (ACT) could theoretically improve curve correction and decrease the incidence of mechanical complications. However, long-term results for TDGR with ACT are limited. The aim of this study was to retrospectively review and compare the outcomes of patients who graduated from TDGR with or without ACT. Patients who were treated by TDGR with or without ACT with a minimum 2-year follow-up after graduation were enrolled. According to the intervention for the apex, patients were further divided into the TDGR group, the TDGR + apical control pedicle screws group (without apical fusion), and the TDGR + hybrid technique group. Clinical outcomes, radiological parameters, pulmonary function, and complications were compared among the 3 groups. A total of 76 patients (51 patients in the TDGR group, 10 patients in the apical control pedicle screws group, and 15 patients in the hybrid technique group) were enrolled. Compared with TDGR, TDGR + ACT achieved better main curve correction, better control of apical vertebral translation and rotation, and lower incidence of complications and revision surgery (P < .05) while maintaining development of the spine and chest. Although the difference was not significant, patients in the TDGR + ACT group had better pulmonary function at the last follow-up (P > .05). The percentage of patients receiving final fusion in the TDGR + ACT group was significantly lower than that in the TDGR group (P < .05). Compared with TDGR, TDGR + ACT can achieve better curve correction and apical control and comparable clinical outcomes while maintaining the growth of the spine and chest. Patients may derive more benefits from treatment with TDGR + ACT, including a lower incidence of mechanical complications and revision surgery, better pulmonary function, and the avoidance of final fusion.

Preoperative and Postoperative Therapeutic Anticoagulation in Orthopaedic Surgery Increases the Risk of Bleeding: A Systematic Review and Meta-Analysis.

Patients requiring postoperative therapeutic anticoagulation may have increased risk of bleeding complications, infection, and poor wound healing. The purpose of this study was to perform a systematic review and meta-analysis assessing bleeding complication rates among orthopaedic surgery patients receiving perioperative therapeutic anticoagulation. A systematic review and meta-analysis was performed in concordance with the Preferred Reporting Items for Systematic Review and Meta Analysis 2020 guidelines. PubMed was queried for articles related to therapeutic anticoagulation in orthopaedic surgery and complications using keywords and medical subject headings. Inclusion/exclusion criteria were any study reporting bleeding complications after orthopaedic surgery among patients on perioperative therapeutic anticoagulation with a minimum 1-year follow-up. Studies were reviewed for heterogeneity and risk of bias. Pooled analysis was done to determine postoperative complication rates among patients on therapeutic anticoagulation. Thirty-seven studies with 3,990 patients were included. Studies were grouped by their surgical subspecialty with 16 from arthroplasty, one foot and ankle, two spine, one sports, 13 trauma, and four upper extremity. Among patients on therapeutic anticoagulation, the pooled rate and 95% confidence intervals of bleeding complications was 8% (5 to 11%) overall, 10% (5 to 15%) in arthroplasty, 6% (3 to 11%) in trauma, and 5% (1 to 30%) in upper extremity. The overall rates (95% CI) of venous thromboembolism (VTE) were 2% (2 to 4%), infection 5% (3 to 10%), and revision surgery 4% (3 to 6%). Upper extremity VTE rates were 0% (0 to 15%), infection 4% (3 to 6%), and revision surgery 4% (3 to 6%). Trauma VTE rates were 4% (2 to 5%), infection 2% (1 to 6%), and revision surgery 3% (2 to 4%). Arthroplasty VTE rates were 2% (1 to 5%), infection 9% (4 to 18%), and revision surgery 4% (2 to 7%). Therapeutic postoperative anticoagulation may increase the risk of bleeding complications when compared with the general population. Incidence of VTE was similar when compared with historical data.

Short-term primary and revision modular dual-mobility cup total hip arthroplasty outcomes in high-risk dislocation patients: a retrospective study

PurposeModular dual-mobility cups (MDMCs) have a lower risk for dislocation after total hip arthroplasty (THA). The primary aims of our study were to analyze implant survivorship and to determine complications, especially dislocation, and revision rates of primary THAs used for hip fracture patients and for revision THAs. Secondary aims were to evaluate mortality after MDMC surgery and to find out if introduction of MDMC at our institution (Kuopio University Hospital, Finland) have decreased dislocation rate.MethodsThis retrospective cohort study consisted of 101 MDMC patients who were consecutively operated at our institution between April 1, 2018 and June 30, 2020. The implant survival rate, complications and mortality were evaluated with minimum of 2-year follow-up. Finnish Hospital Discharge Register was used to find out yearly dislocation rates following THA at our institution.ResultsThe cumulative estimate implant survival after MDMC in the primary THA group was 97% at 2 years, and in the revision THA group, it was 90% at 2 years. Dislocation was a rare complication in the primary THA group (1.4%), while it was common in revision THA group (12.9%). The cumulative estimate for mortality after MDMC in the primary THA group was 13% at 2 years, and in the revision group, it was also 13% at 2 years. The yearly number of patients who had re-hospitalization period due to THA dislocation decreased 46% after implementation of MDMC.ConclusionShort-term survival and complication rates after MDMC were excellent after primary THA and moderate after revision THA. Implementation of MDMC THA for hip fracture patients seems to have effectively decrease dislocation rate during a short follow-up.

Talar head fractures: An observational study of 33 talar head fractures derived from the Swedish Fracture Register

BackgroundReports in the literature on talar head fractures are rare and limited to case reports and small case series. Questions/PurposesThis study aimed to describe a national cohort of talar head fractures for fracture characteristics, associated injuries, treatment, and reoperations. MethodsWe reviewed all radiographs of patients enrolled in the SFR between 2011 and 2021 showing talar head fractures (AO/OTA 81-A3). We excluded those with talar head avulsion fractures, misclassified, multiple registrations, or with a privacy notice in their medical records. The cohort was reviewed using medical records and radiographs at a minimum 2-year follow-up. ResultsThe study included 32 patients (33 fractures) ≥18 years of age. The median age was 32 (range 18–65) years, 84 % were men, and the main trauma mechanisms were motor vehicle accidents (28 %) and falls from heights (28 %) and graded as high-energy injuries in 50 % of the cases. 18 (55 %) were displaced and 15 (45 %) had comminuted fractures. 14 talar head fractures (42 %) had multiple injuries to the same foot. 21 patients (66 %) underwent surgical treatment, most commonly with screw fixation. Surgery was performed in 15 of 18 patients with displaced fractures. Four patients were reoperated, one with arthrodesis of the talonavicular joint and three for implant removal. No cases of avascular necrosis were identified. ConclusionsTalar head fractures are rare and occur mainly in men. They are associated with other foot injuries. Most talar head fractures are treated operatively. In this case series, we did not identify any case of avascular necrosis. Levels of EvidenceIV, retrospective observational cohort study

Minimum 10-year Follow-up after Open Reduction and Internal Fixation of Radial Head Fractures Mason Type II and III

The treatment of complex radial head fractures remains controversial with open reduction and internal fixation (ORIF), radial head arthroplasty, and radial head excision being the most common treatment options. While ORIF is the preferred treatment strategy for Mason type II fractures, the optimal treatment of Mason type III fractures is debated. To report minimum 10-year outcomes after ORIF of Mason type II and type III radial head fractures. We hypothesized that both Mason Type II and Type III fracture patients would demonstrate satisfactory clinical outcomes at minimum 10-year follow-up. All patients with Mason type II or III radial head fractures who were treated with ORIF by a single surgeon between 2005 and 2010 were included. Fractures with significant bone defects were treated with bone grafts and elbow ligament injuries were treated with either primary ligament repair or reconstruction. Patient reported outcome (PRO) questionnaires were administered at the time of last clinical follow-up and at a minimum of 10 years postoperatively. Twenty-four patients, including 13 male and 11 female patients with an average age of 39 (range 19-60) at the time of surgery met inclusion criteria. Thirteen patients suffered from Mason type II and 11 patients from Mason type III fractures. At initial follow-up, 21 out of 24 fractures (88%) demonstrated radiographic union. Three non-unions, 2 of which were Mason type III fractures, were treated with revision ORIF and iliac crest bone grafting. 11 patients developed postoperative elbow stiffness and required capsular release surgery. At last clinical follow-up, average flexion was 139 degrees, average extension was 4 degrees, average supination was 77 degrees, and average pronation was 81 degrees. The median DASH score was 7 (ranging from 0 - 32). Minimum 10-year follow-up (mean: 14.6 years) was collected on 18 of 24 (75%) of the patients. At a minimum of 10 years postoperatively, the median QuickDASH score was 4.5 (range: 0 to 25) and the median SANE score was 96.5 (range: 75-100). Median satisfaction with the surgical outcome was 10/10 (range: 3-10). ORIF of Mason type II and III radial head fractures results in high union rates with good functional outcomes at a mean of 14.6 years postoperatively. The study results suggest that ORIF of Mason type II and III radial head fractures leads to long-term positive functional outcomes.

Long-term Outcomes of Partial Meniscectomy for Degenerative Medial Meniscus Posterior Root Tears.

Previous studies have demonstrated that medial meniscus posterior root tear (MMPRT) repair is superior to debridement in terms of patient-reported outcomes, rates of conversion to total knee arthroplasty (TKA), and long-term costs. Despite the known poor midterm outcomes, there is a paucity of long-term results of partial meniscectomy for degenerative MMPRTs. To 1) evaluate long-term patient-reported and radiographic outcomes of patients who underwent partial medial meniscectomy (PMM) for MMPRTs, and 2) determine the rate of and risk factors for conversion to total knee TKA. Case series; Level of evidence, 4. A previously identified cohort of 26 patients treated with partial meniscectomy for isolated MMPRTs between 2005 and 2013 was prospectively followed for long-term outcomes at a minimum 10-year follow-up. Patients were evaluated for International Knee Documentation Committee (IKDC) outcome score, reoperation, and conversion to TKA. Failure was defined as conversion to arthroplasty or a severely abnormal IKDC subjective score <75.4. This study included 26 patients (10 men, 16 women; mean age, 54 ± 8.7 years [range, 38-71 years] at diagnosis; body mass index, 32.9 ± 5.5) who were followed for a mean of 14.0 ± 3.6 years (range, 10.1-19.6 years). At the final follow-up, 1 patient was deceased and 18 (72%) of the remaining 25 patients had progressed to TKA, with 1 (4%) patient undergoing repeat meniscectomy. The 6 (24%) patients who had not progressed to TKA or revision surgery reported a mean IKDC score of 57 ± 23. Nineteen patients underwent subsequent surgery and 5 demonstrated severely abnormal IKDC scores resulting in a clinical failure rate of 96% (24 of the 25 living patients) at a mean 14-year follow-up. PMM for medial meniscus posterior horn root tears demonstrated 72% progression to TKA and 96% failure according to subjective clinical outcomes at a minimum 10-year follow-up.

The Use of a Suture Bridge Technique for Arthroscopic Rotator Cuff Repair in Patients Under 40 Years of Age Resulted in Successful Tendon Healing, Pain Relief, Improved Shoulder Function, and High Patient Satisfaction at a Minimum of 5-Year Follow-Up

PurposeThe purpose of this study was to evaluate the long-term clinical and imaging outcomes after arthroscopic repair of rotator cuff tear (RCT) using a suture bridge technique in patients under 40 years of age. MethodA consecutive series of patients who were treated arthroscopically for RCT by a single surgeon between 2016 and 2018 were retrospectively identified. Both full thickness tears and partial tears were included. Arthroscopic cuff repair employed a knotless double-row suture bridge technique, utilizing braided suture tapes. To assess clinical outcomes, we employed the Constant score, the American Shoulder and Elbow Surgeons score (ASES), a strength score, and a visual analog scale (VAS). Tendon healing was evaluated at 12 months using the Sugaya MRI classification. ResultsA total of 63 patients were included in the study. The mean age at the time of the surgery was 33.6 years (range, 21 to 40) and minimum follow up duration was 5 years. Thirty-nine patients reported occasional sports, eight were professional athletes, while sixteen reported no sportive activity prior to first symptoms. Mean follow-up duration was 66.8 months (range, 62.4 to 88.6 months). A significant improvement was observed in both the Constant score and ASES score. The mean Constant score increased significantly from 39.8 (range, 29 to 52) points to 88.9 (range, 34 to 100) points postoperatively (p < 0.001). Similarly, the ASES score improved significantly from 41.8 (range, 30 to 64) to 90.2 (range, 35 to 100, p < 0.001). Anterior flexion mean improved from 86° (range: 60° to 110°) to 137° (range, 90° to 180°, p < 0.001). Pain significantly decreased after the surgery, VAS descending from 6.3 (range, 3 to 10) to 1.3 (range, 0 to 9) postoperatively. The overall rate of return to previous activities in the cohort was 84% at an average of 10.1 months (range, 6 to 12 months) after surgery. Among the included patients, 85% engaging in occasional sports activities and 67% of elite athletes similarly returned to their pre-injury sports levels after 9.8 (range, 6 to 12) months and 10.7 months (range, 6 to 12) respectively. Two patients (3%) experienced cuff re-rupture, and tendon non-healing (Sugaya stage 3 and stage 4) was observed in five (7%) patients. At the final follow-up, 95% of patients were very satisfied or satisfied with their functional results. ConclusionThe use of a suture bridge technique in arthroscopic RCT repair for patients under 40 years of age resulted in excellent long-term outcomes, including successful tendon healing, pain relief, improved shoulder function, and high patient satisfaction.

Outcomes After Percutaneous Zadek Osteotomy for Insertional Achilles Tendinopathy.

Surgical treatment of insertional Achilles tendinopathy (IAT) historically consists of Achilles tendon debridement with reattachment and excision of the posterosuperior calcaneal prominence with or without a gastrocnemius recession. Zadek osteotomy (ZO) is an alternative to an open midline splitting approach. The purpose of this study was to analyze patient-reported outcomes and complications after percutaneously performed ZO with minimum 2 years' follow-up. One hundred eight cases treated with percutaneous ZO with a minimum 2-year follow-up were retrospectively reviewed. Postoperative complications and patient satisfaction were evaluated. Foot Function Index (FFI) and visual analog scale (VAS) scores were recorded at preoperative and follow-up appointments to measure patients' functional outcomes and pain, respectively. Mean follow-up was 41.2 months (range, 24-65). Mean age was 51.8 years (range, 28-81). The mean FFI score improved from 56.1 (range, 47-88) to 11.0 (range, 7-59) postoperatively (P < .001). The mean VAS score improved from 7.7 (range, 5-10) to 0.4 (range, 0-7) postoperatively (P < .001). The overall complication rate was 3.8% (n = 4). Of 104 cases, 98.1% of patients said they were satisfied with their procedure (n = 102) when asked if they were satisfied with their ZO and recovery. We found the percutaneous ZO to be a safe and effective intervention for treatment of IAT. At a minimum of 2-year follow-up, this intervention is associated with minimal complications, improved function, reduced pain, and a high rate of patient satisfaction.

Outcomes After Extracorporeal Shockwave Therapy for Chronic Noninsertional Achilles Tendinopathy Compared With Chronic Insertional Achilles Tendinopathy: A Retrospective Review.

Extracorporeal shockwave therapy (ESWT) is a noninvasive treatment modality that is used in the treatment of chronic Achilles tendinopathy (AT). To (1) retrospectively assess outcomes after ESWT for both noninsertional AT (NAT) and insertional AT (IAT) at >1-year follow-up and (2) identify potential predictors of outcomes. Cohort study; Level of evidence, 3. Chart review was conducted to identify patients who underwent ESWT for AT with a minimum of 1-year follow-up. Data collected and assessed included patient demographic characteristics, pathological characteristics including the location of AT (NAT or IAT), presence of a Haglund deformity, and severity of tendon degeneration on magnetic resonance imaging (MRI), in addition to treatment characteristics including number of sessions and intensity of ESWT. The Victorian Institute of Sports Assessment-Achilles (VISA-A) and visual analog scale (VAS) pain scores were obtained before ESWT, 6 months after ESWT, and at final follow-up. Failures were also recorded, which were defined as no improvement in VISA-A or VAS scores or need for surgical intervention. Linear regression was performed to identify potential predictors of inferior subjective clinical outcomes and failures. Survival analysis was conducted using Kaplan-Meier curves. The study included 52 patients with IAT and 34 patients with NAT. The mean follow-up in the NAT cohort was 22.3 ± 10.2 months and the mean follow-up in the IAT cohort was 26.8 ± 15.8 months. Improvements in VISA-A and VAS scores were observed in the NAT cohort at 6-month follow-up and at final follow-up (P < .05). Improvements in VISA-A and VAS scores were recorded in the IAT cohort at 6-month follow-up, which subsequently deteriorated at final follow-up. In the NAT cohort, the failure rate at 6-month follow-up was 11.8%, which increased to 29.4% at final follow-up. In the IAT cohort, the failure rate at 6-month follow-up was 32.7%, which increased to 59.6% at final follow-up. Predictors of inferior subjective clinical outcomes and failures in the NAT cohort included pre-ESWT subjective clinical score, male sex, presence of a cardiovascular risk factor, and more severe MRI grading of tendinopathy. Predictors of inferior subjective clinical outcomes and failures in the IAT cohort included pre-ESWT subjective clinical score and more severe MRI grading of tendinopathy. Superior subjective clinical outcomes together with a lower failure rate were maintained for >1 year in the NAT cohort compared with the IAT cohort, calling into question the long-term benefit of ESWT for patients with IAT.

Effect of Medial or Lateral Graft Failure on Graft Volume and Clinical Outcomes After Superior Capsule Reconstruction for Irreparable Rotator Cuff Tears

Background: Graft failure is a common complication after superior capsule reconstruction (SCR). The graft in SCR is fixed on the greater tuberosity and superior glenoid, and graft failure has been reported on both sides. Purpose: To evaluate the clinical manifestations of patients with graft failure after SCR and identify the clinical and radiological differences between medial and lateral graft failure. Study Design: Cohort study; Level of evidence, 3. Methods: Patients who underwent SCR with a dermal allograft for symptomatic irreparable rotator cuff tears between March 2018 and September 2021 were retrospectively reviewed. All patients had minimum 2-year follow-up and underwent magnetic resonance imaging at 6 months postoperatively. Patients with graft failure were divided into 2 groups: those with lateral graft failure on the greater tuberosity side (group I) and those with medial graft failure on the glenoid side (group II). Patients with intact grafts were included in group III as a control group. Intergroup differences in clinical and radiological characteristics were analyzed, and multiple regression analysis was performed. Results: Among the 93 patients included, there were 18 patients in group I, 15 in group II, and 60 in group III. Overall, 11 patients (61.1%) in group I and 9 patients (60.0%) in group II had a partial graft rupture at one anchor. The postoperative graft volume was significantly lower in group I than in groups II and III (2514.0 ± 564.3 mm3, 3183.5 ± 547.1 mm3, and 3198.0 ± 584.8 mm3, respectively; P = .002 for group I vs II; P < .001 for group I vs III). The acromiohumeral distance (AHD) was significantly increased at 6 months postoperatively compared with before surgery in group I (6.6 ± 1.6 mm vs 4.3 ± 1.9 mm, respectively; P < .001) and group II (7.4 ± 1.3 mm vs 5.7 ± 1.7 mm, respectively; P = .002). However, group I exhibited a significantly greater decrease in the AHD over time than group II (P < .001) and a significantly lower AHD at the final follow-up than the other groups (P < .001). The postoperative American Shoulder and Elbow Surgeons score was significantly lower in group I than in the other groups (P < .001). On multiple regression analysis, fatty infiltration of the infraspinatus muscle, Hamada grade, and graft width were independent factors for lateral graft failure. Conclusion: Patients with lateral graft failure had inferior clinical outcomes and lower postoperative graft volumes than those with medial graft failure after SCR using a dermal allograft. The AHD of patients with lateral graft failure improved postoperatively; however, it deteriorated over time.

The effect of socioeconomic status on clinical outcomes and implant survivorship after primary anatomic and reverse total shoulder arthroplasty

BackgroundLow socioeconomic status has been shown to contribute to poor outcomes in patients undergoing joint replacement surgery. However, there is a paucity of studies investigating shoulder arthroplasty. The purpose of this study was to evaluate the effect of socioeconomic status on baseline and postoperative outcome scores and implant survivorship after anatomic and reverse primary total shoulder arthroplasty (TSA). MethodsA retrospective review of a prospectively-collected single-institution database was performed to identify patients who underwent primary TSA. Zip codes were collected and converted to Area Deprivation Index (ADI) scores. We performed a correlation analysis between national ADI scores and preoperative, postoperative, and pre- to postoperative improvement in range of motion, shoulder strength, and functional outcome scores in patients with minimum 2-year follow-up. Patients were additionally grouped into groups according to their national ADI. Achievement of the MCID, SCB, and PASS and revision-free survivorship were compared between groups. ResultsA total of 1,148 procedures including 415 anatomic and 733 reverse total shoulder arthroplasties with a mean age of 64 ± 8.2 and 69.9 ± 8.0 years, respectively, were included. The mean follow-up was 6.3 ± 3.6 years for anatomic and 4.9 ± 2.7 years for reverse TSA. We identified a weak negative correlation between national ADI and most functional outcome scores and range of motion preoperatively (R range 0.07 to 0.16), postoperatively (R range 0.09 to 0.14), and pre- to postoperative improvement (R range 0.01 to 0.17). Thus, greater area deprivation was weakly associated with poorer function preoperatively, poorer final outcomes and poorer improvement in outcomes. There was no difference in the proportion of each ADI group achieving MCID, SCB, and PASS in the anatomic TSA cohort. However, in the reverse TSA cohort, the proportion of patients achieving MCID, SCB, and PASS decreased with greater deprivation. There was no difference in survivorship between ADI groups . ConclusionsWe found a negative effect of low socioeconomic status on baseline and postoperative patient outcomes and range-of-motion; however, the correlations were relatively weak. Patients that reside in socioeconomically deprived areas have poorer functional outcomes before and after TSA and achieve less improvement from surgery. We should strive to identify modifiable factors to improve the success of TSA in socioeconomically deprived areas.

Change of Sacral Slope according to the Surgical Position in Total Hip Arthroplasty.

Pelvis tilting in sagittal plane influences the acetabular cup position. Majority of total hip arthroplasty (THA) are performed in lateral decubitus surgical position. This study is to assess whether there is any difference in sacral slope between standing and lateral decubitus position and influence of this variation in planning acetabular cup anteversion. This is a prospective study including 50 patients operated between January 2020 to March 2022. Preoperative radiograph included lumbosacral spine lateral X-ray in standing, supine and lateral decubitus positions to calculate the sacral slope for assessment of anterior or posterior pelvic tilting. In our study, we determined the position of the acetabular cup based on changes in sacral slope between standing and lateral decubitus postures. For patients whose sacral slope increased from lateral decubitus to standing, we implanted the acetabular component with a higher degree of anteversion. Conversely, for patients with reverse phenomenon, the cup was inserted at lower anteversion. Twenty-four patients (48.0%) had increase in sacral slope from lateral decubitus to standing whereas 26 patients (52.0%) had decrease in sacral slope. There was linear correlation between difference in preoperative sacral slope and postoperative cross table lateral cup anteversion. Harris hip scores improved from 40.78 to 85.43. There was no subluxation or dislocation in any patient at minimum 2-year follow-up. Individualized acetabular cup placement is important for better functional outcome in THA. Evaluation of pelvic tilting in lateral decubitus position is necessary for better positioning of acetabular cup and avoid postoperative complications.

Superior Capsule Reconstruction for Irreparable Rotator Cuff Tears Yields Good Clinical Outcomes for Patients With and Without Diabetes Mellitus

PurposeTo compare the clinical outcomes after superior capsule reconstruction (SCR) for irreparable rotator cuff tears (RCTs) in patients with and without diabetes mellitus (DM). MethodPatients who underwent SCR using fascia lata autograft for irreparable RCTs between 2012 and 2020 with a minimum 2-year follow-up were divided into non-DM and DM groups. Propensity score matching was used to select controls matched for patients’ characteristics. Only patients with HbA1c <8% were eligible. The Visual Analog Scale (VAS) for shoulder pain, American Shoulder and Elbow Surgeons (ASES) and Japanese Orthopaedic Association scores, and acromiohumeral distance were evaluated preoperatively and at 2 years postoperatively. Shoulder active range of motion (ROM) was evaluated preoperatively, at 6 months, 1 year, and 2 years postoperatively. Graft integrity and postoperative complications required additional surgery were evaluated. The Wilcoxon signed-rank test and Mann-Whitney U test were used to compare continuous variables. Pearson’s chi-squared test and Fisher’s exact test were used for categorical variables. The interaction between the postoperative period and ROM were analyzed by Friedman test and Wilcoxon rank sum test with Holm-Sidak post-hoc test. ResultsWe studied 154 patients (non-DM, 130; DM, 24) who underwent SCR. After matching, 21 patients were selected in each group. All clinical outcomes significantly improved at 2 years (all P<0.05) in both groups. We found no significant differences in clinical outcomes and rates of patients who achieved minimal clinically important differences of VAS and ASES scores between the groups (P=0.10-1.0). The rates of graft tear (both 9.5%) and complications (non-DM, 4.8%; DM, 0%) were not significantly different (both P=1.0). ConclusionSCR using fascia lata autograft for irreparable RCTs yields good clinical outcomes, including ROM, in patients with and without DM. No significant differences in postoperative outcomes were observed between the two groups. Level of EvidenceRetrospective cohort study, Level III.

Survivorship and Clinical Outcomes of Reverse Total Shoulder Arthroplasty in Patients with Large Glenoid Defects Using the Stilting Technique and a Baseplate with Central Ingrowth Cage and Peripheral Locking Screws

Stilting is a novel technique used in reverse shoulder arthroplasty (RSA) in patients with significant glenoid bone loss. This technique utilizes peripheral locking screws placed behind an unseated portion of the baseplate, to transmit forces from the baseplate to the cortical surface of the glenoid, without the need for bone grafting. The stilted screw, once locked, provides a fixed angle point of support for an unseated aspect of a baseplate. The primary advantages of this technique are reduced cost compared to a custom implant and reduced operative time compared to bone grafting. We conducted a retrospective, non-randomized, comparative cohort study of 41 patients underwent primary Reverse Shoulder Arthroplasty (RSA) using the Stilting Technique with the Exactech Equinoxe Reverse System (Gainesville, FL, USA) at a single, academic center from the years 2004-2021. Exclusion criteria included age under 18 or over 100, and oncologic or acute fracture RSA indications. Operative data was documented, including implant records, percent baseplate seating, and operative duration. Survivorship was compared among primary stilted-RSA (n=41), bone graft-RSA (n=42), and non-stilted/non-bone grafted RSA (n=1,032) within our institutional shoulder arthroplasty database. A radiographic examination of baseplate failure was also conducted across the study groups. Postoperative functional outcomes were compared in a matched analysis involving patients with a minimum 2-year follow-up between stilted patients and a non-stilted/non-bone grafted control group for primary RSA. All Stilted-RSA cases utilized metal augments and demonstrated a mean baseplate seating of 61% (range 45-75%). For stilted RSAs, survivorship was 100% and 92.6% at 2- and 5-years, compared to 98.3% and 94.6% for non-stilted/non-bone grafted and 96.3% and 79.5% for bone-grafted RSAs (p=0.042). At 5-years, the baseplate-related failure rates were greater in the stilted (7.4%) and the bone-grafted (9.3%) cohorts compared with the non-stilted/non-bone grafted cohort (1.1%, p<0.001). The mean time to baseplate failure was 30 months for stilted RSA. Functional outcomes for primary RSA were statistically similar between stilted and non-stilted patients, including range of motion, Constant, ASES, SST, UCLA, and SPADI scores. The stilted-RSA cohort exhibited noninferior revision and baseplate failure rates to that of bone-grafted RSA. This suggests that stilting may be a viable technique for patients undergoing primary RSA with significant glenoid deformity.

Arthroscopic selective approach to dynamic posterior shoulder instability: long-term follow-up insights

AimsEvaluate outcomes of arthroscopic capsulolabral repair in patients with structural dynamic posterior instability (Moroder classification B2), analyzing factors associated with inferior clinical outcomes or recurrence. The primary hypothesis is that this surgical approach in patients without static structural changes such as excessive glenoid retroversion or dysplastic glenoids will result in satisfactory clinical outcomes and low failure rates. MethodsObservational retrospective analysis in patients diagnosed with posterior structural dynamic instability who underwent arthroscopic capsulolabral repair. Demographic, clinical and radiologic characteristics were registered as well as patient reported outcomes, satisfaction, complications and failure with a minimum 2-year follow-up. Association between these outcomes and preoperative factors was investigated. Results21 patients were included, with an average age of 38.1 years (range 27-51) and a mean follow-up of 68.7 months (range 24-127). At final follow-up the degree of instability was 0 in 19 (90.5%) patients. Overall outcome assessment demonstrated a mean SSV of 82.3 (±15.2), mean WOSI score of 460.1 (±471) and a mean 91.5 (±13) ROWE score. Furthermore, a significant portion of patients returned to sport 71.4% at any level and 57.1% at previous level, and 71.4% reported satisfaction with treatment, while 5 patients (23.8%) had criteria for failure. ConclusionArthroscopic capsulolabral repair in selected patients with type B2 posterior shoulder instability without static posterior findings yielded satisfactory clinical outcomes and low failure rates.

Outcome of Trapeziectomy and Ligament Reconstruction and Tendon Interposition for Patients Aged Less Than 56 Years: A Retrospective Study With a Minimum 5-Year Follow-Up

The purpose of this study was to determine the long-term consequences of trapeziectomy and ligament reconstruction and tendon interposition (LRTI) for trapeziometacarpal osteoarthritis in patients aged less than 56 years. A retrospective study was performed to investigate the outcome of trapeziectomy and LRTI with a follow-up period of greater than 5 years in patients aged less than 56 years at the time of surgery. Patients completed the Disabilities of Arm, Shoulder, and Hand (DASH), the Patient-Rated Wrist Evaluation (PRWE), and a 10-point visual analog score for pain (VAS). Objective assessments included thumb opposition, palmar and radial abduction angles, and grip, lateral key, and thumb tip pinch strengths. Radiographic assessments of the thumb carpometacarpal joint were performed in three planes, and the trapezial space and trapezial space to metacarpal height ratios were calculated. Between January 2005 and December 2017, 105 patients were treated. Forty-eight patients with 58 thumbs returned for review. The mean patient age at the time of surgery was 52.5 years, and 96% of the patients were women. The mean follow-up period from surgery was 11 years. The mean VAS score was 1. A significant association was found between younger age at the time of surgery and increased proximal migration of the metacarpal, between high VAS pain scores and high PRWE and DASH scores, weak grip, lateral key pinch and thumb tip pinch strength, and Kapandji score, and between the follow-up period and increasing VAS pain, PRWE, and DASH scores. Trapeziectomy and LRTI are effective procedures for patients aged less than 56 years. The benefits of surgery should be balanced against the deterioration in the outcome measures of DASH and PRWE and increasing VAS scores with increasing intervals from surgery. Therapeutic IV.

The Arthroscopically Guided Bristow-Latarjet Procedure With Cortical Button Fixation: A Minimum 10-Year Follow-up

Background: Despite improved visualization, the use of arthroscopic surgery to perform the Latarjet procedure has not decreased the rates of complications and glenohumeral osteoarthritis (OA) in the long term. Many of the reported complications are related to the use of screws for bone block fixation with freehand drilling. Purpose: To evaluate the long-term (at a minimum 10-year follow-up) clinical and radiological outcomes of the arthroscopic Bristow-Latarjet procedure using a posterior guided drilling technique and suture button for coracoid bone graft fixation. Study Design: Case series; Level of evidence, 4. Methods: Consecutive patients who underwent the arthroscopic Bristow-Latarjet procedure with suture button fixation between 2011 and 2013 were reviewed by 2 independent evaluators. Complications and revision surgery were recorded, and we evaluated patient-reported outcomes including subjective scores, recurrence of shoulder instability (dislocation or subluxation), range of motion limitations, and return to sports. Patients had radiographs taken at least 10 years after surgery to assess glenohumeral OA according to the Samilson-Prieto classification system and computed tomography scans to assess bone block positioning and healing. Results: A total of 65 consecutive patients (68 shoulders) with a mean follow-up of 135 months (range, 120-156 months) were included. The mean age at the time of surgery was 25 ± 8 years; 7 patients had previous failed Bankart repair. At follow-up, 94% (64/68) of the shoulders had no recurrence of instability. The 4 cases of instability recurrence were traumatic and occurred at 3 weeks (a fall), 4 months, 2 years, and 7 years after surgery. No hardware failures, coracoid fractures, or neurological complications were observed. Overall, 61 patients (94%) were still participating in sports, with 44 (68%) at the same or higher level. Range of motion showed nonsignificant restrictions in external rotation with the arm at the side (7° ± 9°) and with the arm at 90° of abduction (9° ± 10°) compared with the contralateral side. Additionally, 11 shoulders (16%) had some residual anterior apprehension on clinical examination. At last follow-up, 77% (47/61) of the shoulders had no OA development or progression. Previous failed Bankart repair was a risk factor for the development of OA. Patients with OA had significantly lower Subjective Shoulder Value scores (79% vs 91%, respectively; P = .01) and decreased external rotation with the arm at the side (40° vs 65°, respectively; P = .001) compared with patients with no or little OA. Conclusion: The arthroscopically guided Bristow-Latarjet procedure with suture button fixation is a safe and durable surgical treatment method for recurrent anterior shoulder instability, allowing a high rate of return to sports without significant motion restrictions and no or little OA in the long term.

Poorer clinical outcomes after THA in patients with a spinal scoliotic deformity: a case-control study of 268 patients assessed with PROMS

IntroductionSpinal deformities can lead to specific complications after total hip arthroplasty (THA), such as functional leg length discrepancy due to a fixed pelvic obliquity, as well as an increased risk of prosthetic instability due to a lack of adaptive pelvic mobility, but these issues were not investigated in large comparative series. Therefore a retrospective case-control study was done aiming: 1) to analyze the impact of a preoperative scoliotic deformity on the functional outcomes of patients who underwent THA with a minimum 1-year follow-up, 2) to measure the prevalence of scoliosis in both the case and control groups 3) to screen other factors that may be correlated with poorer clinical outcomes in patients who underwent THA, including age, gender, Body Mass index (BMI), American Society of Anesthesiologists (ASA) score, primary THA etiology and postoperative complication occurrence. HypothesisThe presence of scoliosis would have a negative impact on THA outcomes as assessed by PROMs. Materials and methodsA case-control study was conducted using prospectively collected data including 268 patients who underwent THA between January 2009 and December 2021 through a direct anterior approach by the same senior surgeon. Cases were identified based on a 1-year follow-up modified Harris Hip score (mHHS) lower than 81 while controls were defined as patients with an excellent 1-year follow-up mHHS score (equal to or higher than 81). Three controls were randomly matched with each case based on the surgery period. To assess the impact of a concurrent scoliosis on clinical outcomes, a mathematical univariate and multivariate logistic model was used, including other confounding factors (age, gender, ASA score, BMI, Complication occurrence, etiology), to calculate the adjusted odds-ratio. ResultsIn the multivariate analysis, scoliosis was found to be a significant risk factor, with a three-fold higher adjusted odds-ratio of lower mHHS score (adjOR = 3.1; 95 CI:1.4–7, [p < 0.01]). The mean mHHS score was significantly lower in the scoliosis group compared to the non-scoliosis group (77 vs. 84 [p = 0.01]) as well as the mean Oxford Hip Score (36 vs. 43 [p < 0.001]). Among the other assessed risk factors, only the occurence of a postoperative complication was associated with an increased odds ratio of poorer mHHS scores (adjOR = 7.1; 95 CI: 2.78–18.24, [p < 0.001]). The prevalence of scoliosis in our practice was 19%. Discussion: Given the prevalence of 19% found in our study, we recommend screening for scoliosis in all patients scheduled for THA. Our results indicate that patients who had scoliosis experienced lower PROMs scores compared to those who had not. Surgeons should consider delivering this information to patients who have scoliosis undergoing THA to mitigate patient dissatisfaction. Level of evidenceIII; retrospective case-control study.

Clinical results of carpal tunnel Re-release revision surgery and synovial wrap for recurrent carpal tunnel syndrome

IntroductionCarpal tunnel syndrome is a challenging condition when conventional carpal tunnel revision surgery fails to alleviate symptoms. This study aims to assess the outcomes of combining carpal tunnel revision surgery with a synovial wrap for cases of recurrent carpal tunnel syndrome in patients who had adhered median nerve, with a minimum 1-year follow-up. Patients and methodsA retrospective analysis was conducted on 10 patients (mean age: 73.7 years, nine females and one male) who underwent treatment for recurrent carpal tunnel syndrome. The approach involved carpal tunnel revision surgery coupled with a median nerve synovial wrap. Patients were followed up for a minimum of 1 year. The procedure involved harvesting a 3.5 cm × 4 cm section of the flexor synovial membrane with a distal ulnar pedicle, which was then wrapped around the adherent site of the median nerve. Physical assessments included the pain visual analogue scale (VAS), Tinel sign in the carpal tunnel, thenar muscle atrophy, the Semmes-Weinstein monofilament test (SW test), manual muscle test (MMT) as assessed on the 5-point British Medical Research Council Scale (5/5, normal; 0/5, absent), and the Disabilities of the Arm, Shoulder, and Hand (Quick DASH) questionnaire. The physical variables were compared before surgery and at final follow-up. ResultsAll patients showed some improvement in SW test. The MMT for the abductor pollicis brevis showed significant improvement at final follow-up (3 for four patients, 4 for four patients, and 5 for two patients) compared to pre-surgery assessments (2 for six patients, 3 for two patients, and 4 for two patients). The mean VAS score and DASH score at final follow-up (13.0 ± 10.3, 19.3 ± 12.7, respectively) were significantly lower than those recorded before surgery (76.5 ± 11.1, 52.4 ± 17.1, respectively). The Tinel sign and the thenar muscle atrophy significantly improved from before surgery to final follow-up. ConclusionCarpal tunnel release with a synovial wrap demonstrated significant improvements in muscle strength, pain relief and function. The synovial wrap method is an effective procedure for treating recurrent carpal tunnel syndrome.

Reoperation Rates of Meniscal Repair Are Associated With a Higher Reoperation Rate Than Meniscectomy in Patients Aged 40 and Older

To compare the long-term reoperation rates of meniscectomy and meniscal repair and to determine patient and surgical factors associated with earlier reoperation among patients ≥40 years. A retrospective study was conducted using the IBM MarketScan Commercial Claims and Encounters Database from January 1, 2006, through December 31, 2020. Patients 40 and older who received a meniscectomy or a meniscal repair with a minimum 1-year follow-up were included. The primary outcome was ipsilateral knee reoperation during the study period. Kaplan-Meier survival curves were used to determine differences in reoperation rates for meniscal repair and meniscectomy over time. Multivariable Cox regression analysis was performed to identify factors associated with earlier time to reoperation. A total of 3,026 patients (2,367 meniscectomy, 659 meniscal repair) were included. Mean follow-up was 14.5 ± 0.29 years (range, 1.0-14.91 years). There were no significant differences in baseline demographic characteristics of follow-up between the 2 groups. The survival curves of the 2 procedures significantly differed (P= .02), and the overall reoperation rate was higher after meniscal repair than meniscectomy (13.5% vs 10.1%, P= .01). However, the incidence of subsequent ipsilateral meniscectomy, meniscal repair, and knee arthroplasty procedures did not significantly differ. Multivariable Cox regression analysis identified meniscal repair, obesity, concomitant anterior cruciate ligament reconstruction, and increasing age as being significant risks for earlier reoperation, and male sex was protective. In a population of patients aged ≥40 with surgically treated meniscal tears and 14.5-year average follow-up, meniscal repair was associated with higher overall reoperation with shorter survival times compared to meniscectomy. However, the indications for the 2 procedures likely differed. Additionally, obesity, older age, female sex, and concomitant anterior cruciate ligament reconstruction were risk factors for earlier reoperation. Level III, retrospective comparative case series.
