Outcomes of Arthroscopic Latarjet as a Revision Surgery After Failed Arthroscopic Bankart Repair

Background: The role of arthroscopic Latarjet as a revision surgery after failed arthroscopic Bankart repair has yet to be established. Purpose: To compare clinical outcomes, recurrences, and complication rates of arthroscopic Latarjet as a revision procedure after failed arthroscopic Bankart repair versus arthroscopic Latarjet as a primary procedure. Design: Cohort study; Level of evidence, 3. Methods: This is a retrospective study of prospectively collected data of patients who were diagnosed with anterior shoulder instability and underwent arthroscopic Latarjet stabilization between 2009 and 2018. Patients were separated into 2 groups depending on whether Latarjet was performed after a previous instability surgery (revision) or as a primary surgery (primary). Rowe score, Western Ontario Shoulder Instability Index (WOSI), Constant-Murley Shoulder Outcome (CMSO) score, and Single Assessment Numeric Evaluation (SANE) were assessed pre- and postoperatively with a minimum 24 months of follow-up. In addition, pre- and postoperative levels of sports activity, dislocations, subluxations, and complications were assessed. Results: A total of 97 patients (n = 62 revision; n = 35 primary), with a mean age of 31.0 ± 8.8 and 29.4 ± 7.6 years old in the revision and primary Latajet group, respectively, met the inclusion criteria. The mean follow-up in the revision group was 32 months (24-53) and 35.5 months (27.7-42.2) in the primary Latarjet group. No significant differences between groups were observed in Rowe score (revision = 91.4, primary = 94.1; P = .223), CMSO score (revision = 90.7, primary = 94; P = .105), and SANE (revision = 85.8, primary = 87.3; P = .683) postoperatively. However, the postoperative difference in the WOSI score between the revision and primary Latarjet groups was nearly significant (510 ± 334 vs 403 ± 343, respectively; P = .05). Four (6.4%) postoperative dislocations were reported in the revision and 1 (2.8%) in the primary Latarjet group (P = .14). Patients in the revision group had a lower return to the previous level of sports participation (P = .008) and decreased external rotation with the arm by the side compared with the primary Latarjet group (P = .000). Conclusion: Arthroscopic Latarjet as a revision surgery is a reasonable surgical option in failed Bankart repair cases. The decision to perform arthroscopic Latarjet stabilization as a revision surgery should not be influenced by the potential risk of future complications as it provides comparable clinical outcomes to the primary Latarjet procedure with a low postoperative recurrence rate. However, a decreased level of postoperative sports participation and external rotation with the arm by the side can be expected.

Urinary Incontinence and Other Pelvic Floor Dysfunctions as Underestimated Problems in People under Forty Years: What Is Their Relationship with Sport?

Urinary incontinence is still an underestimated problem due to its anatomical complexity and social taboo. Most of the time, it is believed to affect predominantly the elderly female population, and the literature still lacks data on its presence in the younger and male populations. Its relationship with other pelvic floor dysfunctions (PFDs) and sport activity remains an open topic. Thus, the present study surveyed 342 subjects of both genders, ranging from 18 to 39 y/o and with different sport activity levels, to understand the prevalence of PFDs (such as haemorrhoids, anal fissures, involuntary urinary/faecal leakage, and urgency). The results also showed a significative prevalence in younger, sporty, and male people. Approximately one third of the population had urinary incontinence mostly during stress activities (sport activity: 17%, cough/sneeze: 13%). The statistical analysis confirmed a higher prevalence in the cases of a light (32%) and intense (41%) sport activity level and a protective role of sport if practiced between 5 and 10 h/week, with bodybuilding/CrossFit and running seeming to be the riskiest sports. The relationship with the other PFDs showed a statistically significant dependence with most of them, confirming that urinary incontinence cannot be considered a separate problem from the other PFDs.

Suture Tape Augmentation Improves Posterior Stability After Isolated Posterior Cruciate Ligament Reconstruction Using Hamstring Tendon Autograft With Single-Bundle Transtibial Technique

PurposeThe purpose of this study was to assess whether posterior cruciate ligament reconstruction (PCLR) suture tape augmentation can yield more stability after isolated PCLR. MethodsA prospective database was retrospectively reviewed to identified patients that underwent primary isolated PCLR (control study) or isolated PCLR with suture tape augmentation (study group) from January 2016 to September 2020. the subjective International Knee Documentation Committee Subjective (IKDC) Knee, Lysholm and Tegner scores, posterior draw tests, as well as posterior stress radiographs and return to sports activity rates. The minimal clinically important difference (MCID) was used to evaluate the clinically relevance (subjective IKDC, Lysholm and Tegner scores). Results59 were included in this analysis (28 patients in control group, 31 patients in study group). The average length of follow-up was similar between the study and control groups (48.6 vs 47.9months; p=0.800). Knee function, in terms of subjective IKDC (study vs. control: 85.1±6.4 vs. 79.8±6.4; P=0.002), Lysholm (study vs. control: 86.3±7.4 vs. 80.8±7.4; P=0.005) and Tegner (study vs. control: 7.0±1.4 vs. 5.6±1. 7; P=0.006) scores, was significantly improved in the study group. However, the differences between control group and study group were less than the MCID in the subjective IKDC score and Lysholm score. 21.4% (6/28) and 48.4% of patients (15/31) in the control and study groups, respectively, returned to the preinjury sports activity levels (P=0.031). At last follow-up, the mean side-to-side differences in posterior laxity was significantly improved in the study group compared with the control patients (study vs. control: 1.52±0.70 mm vs. 3.17±2.01 mm; p<0.01). ConclusionsPrimary isolated PCLR with suture tape augmentation provides better posterior stability than PCLR without suture tape augmentation at a minimum 2 years follow-up. No differences observed between the groups in the percentage of patients who met or exceeded the MCID in subjective IKDC and Lysholm score.

Hair and dietary supplements testing to identify contamination with roxadustat in an adverse analytical finding

Roxadustat is an oral inhibitor of hypoxia-inducible factor (HIF) prolyl hydroxylase, which increases endogenous erythropoiesis. WADA has included roxadustat and other HIF stabilizers on its list of prohibited substances. We describe here the case of an elite athlete (female, 31 years old, 168 cm and 53 kg) with an adverse analytical finding (AAF) with concentration of roxadustat in her urine at 0.289 ng/mL in the A sample and 0.529 ng/mL in the B sample (83% higher than A). A stability study was carried out, showing total stability of roxadustat at this concentration in urine exposed to light for 50 h, so photoisomerization degradation cannot explain the difference in concentration. Her urine had been completely negative in a control test carried out three days previously, while roxadustat had been shown to be present in urine for at least 20 days after administration of pharmacologically effective doses to an athlete. Hair concentration was 0.39 and 0.35 pg/mg in the segments corresponding to the presumed period of intake, with few adjacent segments also positive (0.29–0.33 pg/mg), likely explained by cosmetic treatments. Concentrations found in a patient treated with a pharmacologically active dose (between 100 and 120 mg 3 days a week) were more than 100 times higher (between 41 and 57 pg/mg). Numerous supplements and pharmaceuticals taken by the athlete were analyzed. Only collagen powder showed the presence of roxadustat, at a very low but highly variable concentration (100 pg/g-1000 pg/g). A female volunteer (58 years old, 169 cm and 65 kg), taking this powder at the same doses as the athlete (10 g of powder 5 times for 6 days) presented 7 roxadustat-positive urine samples (although lower than those observed in the athlete) out of 34 sampled over 7 days, the difference in powder sampling location, age, weight, height, pharmacokinetic parameters variability and level of sporting activity between the athlete and the volunteer probably explaining the difference in concentrations observed. All these results could be consistent with an AAF due to contamination by dietary supplements, which are becoming increasingly common due to the current exposome of athletes in our society.

Arthroereisis with a Talar Screw in Symptomatic Flexible Flatfoot in Children

Background: Pes planovalgus, or flexible flatfoot, deformity is a common problem in pediatric orthopedic patients. There is no consensus on using the technique of arthroereisis in the treatment of symptomatic pes planovalgus. The aim of our study was to prospectively assess the functional outcomes following symptomatic pes planovalgus treatment with the use of the Spherus talar screw. Methods: Twenty-seven patients (11 females, 16 males), at a mean age of 10.5 years (7–14 years) were included in the prospective study. We assessed the level of physical activity (including sports) based on the University of California, Los Angeles (UCLA) activity scale, a 10-point level-of-activity VAS scale, and the Grimby physical activity scale. Pain was assessed based on a VAS pain scale; foot function was assessed with the revised Foot Function Index (FFI-R); and ankle joint mobility was measured. Results: The mean follow-up period was 18 months (14–26 months). There was a significant improvement in VAS-measured physical activity scores from 5.47 to 7 at follow-up, p = 0.048. There was a significant improvement in UCLA activity scale scores from 4.78 to 6.05 at follow-up, p = 0.045. Pain levels decreased from a mean VAS score of 4.73 prior to surgery to a mean score of 2.73 at follow-up, p = 0.047. The functional FFI-R scores showed a significant improvement from 140 points prior to surgery to 97.75 points at follow-up, p = 0.017. Comparison of the preoperative and follow-up values of the range of plantar flexion, adduction, and abduction in the operated limb also showed no significant changes in those individual parameters. The mean values of dorsiflexion, plantar flexion, adduction, and abduction at the ankle joint at follow-up, compared individually between the operated and non-operated foot showed no statistically significant differences. Conclusions: The use of a talar screw in the treatment of symptomatic pes planovalgus helps reduce pain and improve functional outcomes after treatment. Foot function assessments showed diminished pain, improved levels of physical and sport activity, and no effect on the range of motion after surgery in comparison with preoperative data. Arthroereisis with a talar screw is a valid surgical technique for the treatment of symptomatic pes planovalgus.

Predictive Factors Influencing the Return to Sports Following Arthroscopic Knee Meniscectomy in Sports Persons: A Prospective Cohort Study.

Meniscus tears are among the common knee injuries in sports, with arthroscopic meniscectomy being one of the most commonly performed orthopedic procedures. Return to sports of the same level following arthroscopic meniscectomy is an important aspect for athletes. Numerous factors may influence the time required for athletes to resume sports activities after meniscectomy. This prospective cohort study aimed to investigate the timeframe for returning to sports in athletes who underwent arthroscopic meniscectomy and to identify predictive factors that influence this return. Ninety sports persons who had undergone arthroscopic meniscectomy were included in this study. The patients were analyzed for their time to return to sports and nine proposed predictive factors that may influence their return to sports. Out of the 90 participants, 75 were able to return to their previous activity level, while the remaining 15 were unable to do so. Among the nine pre-defined factors studied, age older than 25 years (p < 0.0001), participation in non-contact sports (p < 0.0001), and engagement in recreational activities (p < 0.0001) were found to be statistically significant. In conclusion, this study reveals that with the increase in age, time to return to sports following arthroscopic meniscectomy increases. Additionally, athletes involved in non-contact sports and those havingrecreational sports activity levels experience greater delays in their return to sports as compared to athletes involved in combat and contact sports and athletes having elite and competitive sports levels, respectively.

Concomitant Biceps Tenodesis Does Not Portend Inferior Outcomes After Anterior Glenohumeral Stabilization

Background: Military patients are known to suffer disproportionately high rates of glenohumeral instability as well as superior labrum anterior to posterior (SLAP) tears. Additionally, a concomitant SLAP tear is frequently observed in patients with anterior shoulder instability. Even though biceps tenodesis has been demonstrated to produce superior outcomes to SLAP repair in military patients with isolated SLAP lesions, no existing studies have reported on outcomes after simultaneous tenodesis and anterior labral repair in patients with co-existing abnormalities. Purpose: To evaluate outcomes after simultaneous arthroscopic-assisted subpectoral biceps tenodesis and anterior labral repair in military patients younger than 40 years. We also sought to compare these outcomes with those after repair of an isolated anterior labral tear. Study Design: Cohort study; Level of evidence, 3. Methods: This study is a retrospective analysis of all military patients younger than 40 years from a single base who underwent arthroscopic anterior glenohumeral stabilization with or without concomitant biceps tenodesis between January 2010 and December 2019. Patients with glenoid bone loss of >13.5% were not eligible for inclusion. Outcome measures including the visual analog scale (VAS) for pain, the Single Assessment Numeric Evaluation (SANE), the American Shoulder and Elbow Surgeons (ASES) shoulder score, the Rowe instability score, and range of motion were administered preoperatively and postoperatively, and scores were compared between groups. Results: A total of 82 patients met inclusion criteria for the study. All patients were active-duty service members at the time of surgery. The mean follow-up was 87.75 ± 27.05 months in the repair + tenodesis group and 94.07 ± 28.72 months in the isolated repair group (P = .3085). Patients who underwent repair + tenodesis had significantly worse preoperative VAS pain (6.85 ± 1.86 vs 5.02 ± 2.07, respectively; P < .001), ASES (51.78 ± 11.89 vs 62.43 ± 12.35, respectively; P = .0002), and Rowe (26.75 ± 7.81 vs 37.26 ± 14.91, respectively; P = .0002) scores than patients who underwent isolated repair. Both groups experienced significant improvements in outcome scores postoperatively (P < .0001 for all), and there were no statistically significant differences in postoperative outcome scores or range of motion between groups. There were no differences in the percentage of patients who achieved the minimal clinically important difference, substantial clinical benefit, and patient acceptable symptom state for the VAS pain, SANE, ASES, and Rowe scores between groups. Overall, 37 of the 40 (92.50%) patients in the repair + tenodesis group and 40 of the 42 (95.24%) patients in the isolated repair group returned to unrestricted active-duty military service (P = .6045). In addition, 38 (95.00%) patients in the repair + tenodesis group and 40 (95.24%) patients in the isolated repair group returned to preinjury levels of sporting activity (P = .9600). There were no significant differences in the number of failures, revision surgical procedures, or patients discharged from the military between groups (P = .9421, P = .9400, and P = .6045, respectively). Conclusion: The findings of this study indicate that simultaneous biceps tenodesis and labral repair was a viable treatment option for the management of concomitant SLAP and anterior labral lesions in young, active military patients younger than 40 years.

Muti-factor analysis of sport activity level after high tibial osteotomy

BackgroundAlthough many studies have shown that high tibial osteotomy is appropriate for active patients, there are limited multifactorial studies on patients’ sport activity level after HTO in general population.Methods158 patients who underwent HTO for knee osteoarthritis between January 2016 and December 2019 are included, with a 36-month follow-up. Information was collected from X-rays and questionnaire. The independent variables were age, sex, breadwinner (provide more than 50% income), sport activity level when the knee was pain-free before and after surgery, concomitant meniscal treatment history, Lysholm knee score, desire level for returning to sports. The 158 cases are divided into three groups according to their sports participation before and after operation, Chi-square tests and ANOVA analysis were adopted to identify the effect of these variables on sport activity level after HTO, and factors with statistical differences and clinical relevancies, or provided by previous research were assessed with the ordinal logistic regression analysis.ResultsAccording to sport activity level analysis, 28(17.7%) patients were categorized into the sport level-reduced group, 97(61.4%) patients into the sport level-unchanged group, and 33(20.9%) patients into the sport level-improved group. Upon ordinal logistic regression analysis, postoperative MA%, age, BMI, and preoperative Lysholm knee score were statistically significant.ConclusionsHigher postoperative MA%, younger age, lower BMI, and lower Lysholm score are associate with improvement on activity level after HTO. This finding provides valuable references in operation option and rehabilitation planning.

Effectiveness of Hospital-Based Systemic Rehabilitation in Improving Ankle Function after Surgery in Chronic Ankle Instability Patients

Category: Sports; Other Introduction/Purpose: We investigated the therapeutic effect of a postoperative hospital-based systemic rehabilitation protocol on ankle function in chronic ankle instability (CAI) patients. Methods: Thirty-five patients who underwent a modified Broström procedure for CAI were recruited in this prospective randomized controlled trial. Fifty-minute sessions of hospital-based rehabilitation were performed three times weekly for 12 weeks in the intervention group. Education-based rehabilitation was conducted at home in the control group. The outcomes were evaluated at baseline (T0), 12 weeks (T1), and 16 weeks (T2). The primary outcome was the foot and ankle outcome score (FAOS). Ankle motor strength and spatiotemporal gait metrics were assessed as secondary outcomes. Results: There were time and group interaction effects on the pain, symptoms, activities of daily living, sports activities, and quality of life (QOL) domains of the FAOS (P &lt; 0.05, all). The patients in the intervention group showed larger improvements in all domains of the FAOS than did the control group at both T1 and T2 (P &lt; 0.05, all). The time and group interaction effects on invertor and evertor strength were also significant (P = 0.047 and P = 0.044). Invertor and evertor strength improved significantly more in the intervention group than in the control group at T1 and T2 (P &lt; 0.05, all). The preferred walking velocity, cadence, step length on the affected side, and double stance phase duration tended to improve over time. Conclusion: Postoperative hospital-based rehabilitation helped improve CAI pain, symptoms, independence in activities of daily living, sports activity levels, and QOL more effectively than did conventional rehabilitation at home.

Failure rate, return-to-sports and magnetic resonance imaging after meniscal repair: 119 patients with 7 years mean follow up.

One of the most important factors to consider in relation to meniscal repair is the high failure rate reported in the existing literature. To evaluate failure rates, return to sports (RTS) rate, clinical outcomes and magnetic resonance image (MRI) evaluation after meniscus suture repair for longitudinal tears at a minimum 2-year-follow-up. We conducted a retrospective review of meniscal repairs between January 2004 and December 2018. All patients treated for longitudinal tears associated or not with an anterior cruciate ligament reconstruction (ACL-R) were included. Meniscal ramp lesions, radial and root tears, associated with multiligament injuries, tibial fracture and meniscal allograft transplants were excluded. Surgical details and failure rate, defined as symptomatic patients who underwent a revision surgery, were analyzed. As isolated bucket handle tears (BHTs) were usually associated with higher failure rates, we compared BHTs and not BHTs associated or not with an ACL-R. Since 2014, the inside-out technique using cannulas and suture needles with 2-0 Tycron began to predominate. In addition, the number of stitches per repair was increased. In view of differences in surgical technique, we compared two different cohorts: before and after 2014. We recorded the RTS according to the level achieved and the time to RTS. Lysholm and IKDC scores were recorded. Patients were studied with x-rays and MRI as standard postoperative control. One hundred and nineteen patients were included with a mean follow up of 7 years (SD: 4.08). Overall failure rate was 20.3% at a mean 20.1 mo. No statistically significant differences were found when comparing failure for medial and lateral meniscal repair (22.7% and 15.3%, P = 0.36), BHTs and not BHTs (26% and 17.6%, P = 0.27), isolated or associated with an ACL-R (22.9% and 18%, P = 0.47), or when comparing only BHTs associated with an ACL-R (23% and 27.7%, P = 0.9) or not. When comparing cohorts before and after 2014, we found a significant decrease in the overall failure rate from 26% to 11% (P < 0.03). Isolated lesions presented a decrease from 28% to 6.6% (P = 0.02), BHTs from 34% to 8% (P = 0.09) and those associated with an ACL-R from 25% to 10% (P = 0.09). Mean RTS time was 6.5 mo in isolated lesions and 8.64 mo when associated with an ACL-R. Overall, 56% of patients returned to the same sport activity level. Mean pre and postoperative Lysholm scores were 64 and 85 (P = 0.02), and IKDC 58 and 70 (P = 0.03). Out of 84 asymptomatic patients evaluated with MRI, 39% were classified as "not healed" and 61% as "healed". Even though the overall failure rate of our series was 20.3%, we found a statistically significant decrease from 26% to 11%, not only for isolated lesions, but also for BHT's and those associated with an ACL-R when comparing our series in two different cohorts, most probably due to improvements in surgical technique.

Successful Return to Sport and Daily Activities After Suture Augmentation of Both the Anterior Talofibular Ligament and Calcaneofibular Ligament

To evaluate the return to sport and daily activities in addition to clinical outcomes after modification of the Brostöm repair, specifically using suture augmentation for concomitant fixation of both the anterior talofibular ligament and calcaneofibular ligament. Patients who had grade III ankle sprains and lateral ankle instability, all of whom failed supervised conservative management, were included. Patients underwent a modified Broström procedure consisting of suture augmentation for both the anterior talofibular ligament and calcaneofibular ligament. For clinical outcome evaluation, Foot and Ankle Ability Measure (FAAM) and Karlsson-Peterson Scoring System for Ankle Function questionnaires coupled with questions regarding time of return to sport and level of sports activity were used. Thirty-one patients were included. The differences in preoperative and postoperative FAAM scores for both the Activities of Daily Living subscale and Sports subscale were significant (P < .001). The FAAM Activities of Daily Living score improved from an average of 46.06 preoperatively to 77.49 postoperatively (P < .001, 99% confidence interval, 26.4-36.4). The FAAM Sports score improved from an average of 4 preoperatively to 19.31 postoperatively (P < .001, 99% confidence interval, 11.6-19.0). For the Karlsson-Peterson Scoring System for Ankle Function, the surveyed population reported a mean of 82.74 points out of 100 post-op (standard deviation 20.14). The mean time to return to sport activity was 5.72 months. Mean follow-up time was 24.12 months. This variant Broström procedure with suture anchors and augmentation of both the anterior talofibular ligament and calcaneofibular ligament was effective in helping patients return to their preinjury functionality level in both daily life and sports activity. Level IV, therapeutic case series.

Outcomes Following Combined Posterior Labral and SLAP Repair in Military Patients Younger Than 35 Years

Background: Members of the military are known to experience disproportionately high rates of both glenohumeral instability and superior labrum anterior-posterior (SLAP) tears when compared with civilian populations. Although the outcomes after simultaneous repair of Bankart and SLAP lesions have been well described, there is a paucity of literature available regarding the operative management of posterior instability with concomitant superior labral pathology. Purpose: To compare outcomes of combined arthroscopic posterior labral and SLAP repair with those of isolated posterior labral repair. Study Design: Cohort study; Level of evidence, 3. Methods: All consecutive patients younger than 35 years who underwent arthroscopic posterior labral repair from January 2011 to December 2016 with a minimum follow-up of 5 years were identified. From this cohort of eligible patients, all individuals who had undergone combined SLAP and posterior labral repair (SLAP cohort) versus posterior labral repair alone (instability cohort) were then identified. Outcome measures including the visual analog scale score, Single Assessment Numeric Evaluation (SANE), American Shoulder and Elbow Surgeons (ASES) score, Rowe instability score, and range of motion were collected pre- and postoperatively and scores were compared between groups. Results: In total, 83 patients met the inclusion criteria for the study. All patients were active-duty military at the time of surgery. The mean follow-up was 93.79 ± 18.06 months in the instability group and 91.24 ± 18.02 months in the SLAP group (P = .5228). Preoperative SANE and ASES scores were significantly worse in the SLAP group. Both groups experienced statistically significant improvements in outcome scores postoperatively (P < .0001 for all), and there were no significant differences in any outcome scores or range of motion between groups. In total, 39 patients in the instability cohort and 37 in the SLAP cohort returned to preinjury levels of work (92.86% vs 90.24%, respectively; P = .7126), and 38 instability patients and 35 SLAP patients returned to preinjury levels of sporting activity (90.48% vs 85.37%, respectively; P = .5195). Two patients in the instability group and 4 patients in the SLAP group were medically discharged from the military (4.76% vs 9.76%; P = .4326), and 2 patients in each cohort had experienced treatment failure at the final follow-up (4.76% vs 4.88%; P > .9999). Conclusion: Combined posterior labral and SLAP repair led to statistically and clinically significant increases in outcome scores and high rates of return to active-duty military service that did not differ significantly from the results after isolated posterior labral repair. The results of this study indicate that simultaneous repair is a viable treatment option for the management of combined lesions in active-duty military patients <35 years of age.

Poster 333: Outcomes of Anterior Closing Wedge High Tibial Osteotomy in Patients Undergoing ACL Revision Reconstruction

Objectives: Graft failure rates following anterior cruciate ligament (ACL) reconstruction have been reported up to 30%. According to the literature, one anatomic variant linked to graft reinjury is a high posterior tibial slope. As a result, surgeons are exploring the effectiveness of slope reducing high tibial osteotomy (HTO) to reduce the subsequent reinjury risk. While cadaveric models indicate that this procedure decreases the forces across the ACL graft, there is limited evidence demonstrating its efficacy in clinical trials. Therefore, the purpose of this study was to compare self-reported patient outcomes between patients undergoing ACL revision surgery with a slope reducing high tibial osteotomy (ACL+HTO) and matched controls undergoing revision ACL reconstruction without slope reducing HTO. We hypothesized that patients undergoing ACL+HTO would exhibit similar outcomes with a low failure rate when compared to their matched counterparts. Methods: A retrospective matched-case control study was conducted for patients undergoing ACL revision reconstruction from 2018 to 2021, utilizing a single surgeon database (n = 1,781). Patients in the HTO group were included if they were at least one year out from surgical ACL reconstruction and slope reducing osteotomy. Patients were excluded if they had a primary ACL reconstruction or no concomitant ACL reconstruction with an HTO. Patients in the ACL+HTO group were age, gender, and setting-matched to a control group of patients undergoing revision ACL reconstruction. Descriptive patient demographic and surgical data were obtained, including pre/postoperative posterior tibial slope (o) for the HTO group. Complications and injury surveillance was conducted throughout the postoperative follow-up period. Primary outcome measures included the Single Assessment Numeric Scale (SANE), and graft failure rates at 24 months. Secondary outcomes included return to sport rate and level, and postoperative complications (infection, loss of motion, deep vein thrombosis, etc). Generalized linear models were conducted using parametric and nonparametric equivalents to compare baseline and outcome measures between groups with an a-priori alpha level of .05. Results: From a group of 364 revision ACL reconstructions, 9 patients met the inclusion criteria for the ACL+HTO group (Table 1). This group was age, gender and revision matched to 30 patients in the control group. Baseline comparisons revealed that the ACL control group weighed more than the experimental group (198.2 ±26.4 vs 183.7 ±21.7, P &lt;.001), however all other comparisons were not statistically different. The mean pre op posterior tibial slope was 19.2o ±4.1o and 7.7o ±2.3o following HTO (mean diff: -11.5o, P &lt;.001). Mean time to follow-up was 1.82 ±0.3 years. At follow-up, there were no statistical differences in self-reported knee function (SANE score), graft reinjury rate, rate of return to sport, or level of return to sport between groups (Table 2). There were no graft reinjuries reported in the ACL+HTO group, and approximately 85.8% returned to some level of sporting activity with 42% returning to a level I or II cutting and pivoting sport. Conclusions: Preliminary evidence provided in the current study suggests that slope reducing HTO in the setting of revision ACL reconstruction for large posterior tibial slope deformities is effective at correcting malalignment and avoiding graft failure out to 2 years. This procedure also holds promise to allow a majority of patients to return to various levels of sporting activities. To our knowledge, this is the first comparative study comparing the intermediate outcomes of this subpopulation to a matched revision ACL cohort. While these data do provide evidence for ongoing investigation, it is important to note that this pilot study is underpowered and we strongly recommend the performance of larger clinical trials to confirm these results.

Results: From a group of 364 revision ACL reconstructions, 9 patients met the inclusion criteria for the ACL+HTO group (Table 1). This group was age, gender and revision matched to 30 patients in the control group. Baseline comparisons revealed that the ACL control group weighed more than the experimental group (198.2 ±26.4 vs 183.7 ±21.7, P &lt;.001), however all other comparisons were not statistically different. The mean pre operative posterior tibial slope was 19.2o ±4.1o and 7.7o ±2.3o following HTO (mean diff: -11.5o, P &lt;.001). Mean time to follow-up was 1.82 ±0.3 years. At follow-up, there were no statistical differences in self-reported knee function (SANE score), graft reinjury rate, rate of return-to- sport, or level of return to sport between groups (Table 3). There were no graft reinjuries reported in the ACL+HTO group and approximately 85.8% returned to some level of sporting activity with 42% returning to a level I or II cutting and pivoting sport. Conclusions: Preliminary evidence provided in the current study suggests that slope reducing HTO in the setting of revision ACL reconstruction for large posterior tibial slope deformities is effective at correcting malalignment and avoiding graft failure out to 2 years. This procedure also holds promise to allow a majority of patients to return to various levels of sporting activities. To our knowledge, this is the first comparative study comparing the intermediate outcomes of this subpopulation to a matched revision ACL cohort. While these data do provide evidence for ongoing investigation, it is important to note that this pilot study is underpowered and we strongly recommend the performance of larger clinical trials to confirm these results.

Posterior Ankle Impingement Syndrome in a Nonathletic Population: Causes, Treatment Modalities, and the Results of Endoscopic Treatment.

A common cause of posterior ankle pain is posterior ankle impingement syndrome (PAIS). Many studies about PAIS have been conducted on special groups such as athletes and dancers; there has been no previous study of a nonathletic population. This study aimed to evaluate the causes and treatment methods of PAIS in the nonathletic population and compare it with the athletic population. A retrospective review was performed and 28 of 46 patients (60.9%) recovered from two-staged conservative therapy. In the 18 patients (39.1%) who did not benefit from 3 months of conservative treatment, hindfoot endoscopy was applied. Patient data, including sex, age, occupation, and sports activity level, were recorded. Visual analog scale, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot, and Tegner scores were recorded. Patient satisfaction was assessed with a 4-point Likert scale. Complications were recorded. Mean follow-up was 27.4 months. At final follow-up, the AOFAS hindfoot score had significantly improved from 66.4 to 96.8 (P < .001). The Tegner score improved significantly from 4.6 to 8.8 (P < .001). The visual analog scale score was 6.4 and increased to 0.9 (P < .001). Using the 4-point Likert scale for patient satisfaction, 13 (72.2%) stated that the surgical procedure was excellent and five (27.8%) good. Mean time to return to work was 4.2 weeks. Sural nerve dysesthesia was seen in two patients (11.1%). This is the first study to evaluate PAIS in the nonathletic population. Conservative treatment showed good results as nearly two-thirds of the patients recovered. Hindfoot endoscopy in those not responding to conservative therapy is a successful treatment with low complication rates.

Poster 342: Anterior Cruciate Ligament Reconstruction in Recreational Athletes Aged 40 and Older: Activity Level as an Indication

Objectives: The number of patients that are continuing to be active is extending into middle age. Many in this population report consistent participation in recreational sports. Anterior cruciate ligament reconstruction (ACLR) is the gold standard for treatment among young athletic patients, but nonoperative treatment has historically been utilized more often in older patient populations. It has been traditionally thought that older adult patients do not share the same activity level as younger patients and thus are not in need of surgical treatment of an ACL injury. There is some hesitancy to treat older patients if they have mild to moderate pre-existing arthritis, but in recent years the literature has demonstrated good outcomes in this population. The type of graft used in older patients is another source of controversy, with many surgeons opting to use allograft rather than a patient’s native tissue for ACLR. Factors that can inform decision-making such as pre-injury activity level and employment have not been thoroughly assessed for these patients. The purpose of this study was to better understand indications for ACLR in patients aged 40 and older by characterizing their activity level, mechanisms of injury, employment status, demographics, surgical characteristics, and patient reported outcomes (PROs). Methods: A registry of prospectively-collected PROs from a single metropolitan ambulatory surgical center was retrospectively reviewed for patients that received an ACLR from 2009-2016. Patients younger than 40 years old, revision procedures, and concomitant ligament repairs or reconstructions were excluded. Demographic, employment, activity, injury, and surgical characteristics were extracted via chart review. The level of strength required by the patient’s occupation was stratified by the definitions from the United States Department of Labor Occupation Requirements Survey (graded as “sedentary”, “light work”, “medium work”, “heavy work”, “very heavy work”). Surgical outcomes include ACLR failure or re-rupture, ipsilateral knee re-operations, and complications. PROs utilized were the Single Assessment Numeric Evaluation (SANE) and Knee Injury &amp; Osteoarthritis Outcome Score (KOOS) collected pre-operatively and at two years post-operatively. Results: A total of 141 patients were identified. More than half the patients were female (n=81, 58%) and the average age was 47 years old (range: 40-66). Approximately 87% (n=124) of patients had PRO data. The average KOOS and SANE at two-year follow-up were 80.0 ± 15.9 and 85.3 ± 22.0, respectively. The average change from baseline score were 20.8 ± 20.2 and 24.1 ± 30.3 for KOOS and SANE, respectively. Pre-existing arthritis was found in the majority of patients (n=88, 62%). The most common graft type used for ACLR in this group was allograft (n=95, 67%). Injured menisci were typically treated with meniscectomy vs repair (n=65, 56%). The majority of patients (n=104, 77%) were engaged in a sport when they sustained an ACL injury, with 96% being engaged in a sport that requires running, jumping, and other high-impact activity. Those injured while involved in a sport on average demonstrated higher KOOS scores at baseline and at two-year follow up compared to those that were not involved in a sport (61.5 ± 18.0 vs 51.6 ± 18.0 at baseline, p=0.045; 82.8 ± 13.7 vs 70.8 ± 19.5 at two years, p=0.0048). A total of 27 of the sporting-related injuries occurred in patients age 50 or older (60% of n=45 patients age 50 years or older). All of these patients expressed a desire to return to sport and pre-injury activity. Skiing was the most frequently cited sport (n=41, 29%). Most ACL injuries were acute, with just 10% found to be chronic. The mechanism of injury varied by activity, but non-contact type ACL injuries were the most prevalent (n=66, 49%). Although most patients worked in a sedentary or desk job environment (n=87, 65%), some worked in very heavy-duty jobs (n=18, 14%). There was a low incidence of re-ruptures and re-operations (4.5% and 8.7%, respectively). Conclusions: The majority of patients aged 40 and over sustained ACL injuries while engaging in sports, with all of these patients citing a desire to return to sport and pre-injury activity level as their reason for wanting an ACLR. Patients were mostly treated with allograft compared to autograft, and meniscal injuries were most frequently treated through meniscectomy instead of repair. Many of these patients had some form of pre-existing arthritis and still went on to have surgery with excellent outcomes. PROs were also found to be higher initially and at two-year follow-up in the more active adult group, suggesting that pre-injury and post-injury activity level is associated with improved outcomes. When an older adult patient presents with an ACL tear, surgeons should consider the activity level and desires of the patient as they determine the appropriate avenue of treatment. There is certainly a role for conducting ACLR in patients aged 40 or older. [Table: see text][Table: see text][Table: see text]

A Suggested Perception of a Course That Takes into Account the Concepts of Health Awareness and Sport Cultures Among Al-Aqsa University Students

This study aims to identify the proposed vision for a course that takes into account the concepts of health awareness and sport culture among Al-Aqsa University students. The study sample includes (64) male and female physical education lecturers in the Arab world for the year 2021, which were chosen randomly. To achieve this, the researcher prepared a list to identify the topics that must be available in the subject of health awareness and sport culture, consisting of (31) paragraphs. The results of the study conclude that the total degree of the specifications required for the development of health awareness and contemporary sport culture at Al-Aqsa University in the light of academic standards from the point of view of physical education lecturers in the Arab world is large with a relative weight of (75.50%). In addition, the results show that there are no statistically significant differences due to the gender variable. The researcher recommends the necessity of activating the level of sport activities for the purpose of developing and enhancing the concepts of health awareness and sport culture for students according to certain foundations and standards, creating the necessary environment for that, and including some subjects related to health, food and sport awareness among the university's compulsory requirements.

Hyaluronic scaffold transplantation with bone marrow concentrate for the treatment of osteochondral lesions of the talus: durable results up to a minimum of 10years.

The aim of this study was to evaluate the long-term clinical results of the transplantation of a hyaluronic acid membrane augmented with bone marrow aspirate concentrate (BMAC) in an one-step technique for the treatment of patients affected by osteochondral lesions of the talus (OLT). A total of 101 patients (64 men, 37 women, age 32.9 ± 10.9) were evaluated for a minimum of 10years of follow-up (151.5 ± 18.4months) The mean lesion size was 2.2 ± 1.4 cm2, the lesion had a post-traumatic origin in 73 patients, 15 patients previously had an ankle fracture, 22 patients had ankle osteoarthritis. All patients were clinically evaluated at baseline and at 2, 5, and a minimum of 10years after treatment using the AOFAS score, the NRS for pain, and the Tegner score. A survival analysis was performed to check the survival to failure up to the last follow-up. The AOFAS score significantly improved from baseline (59.6 ± 13.9) to the final follow-up (82.3 ± 14.2) (p < 0.0005). A significant reduction in the AOFAS score was found from 2 to 10years (p < 0.0005). The NRS for pain changed from 7.0 ± 1.3 at baseline to 3.9 ± 2.7 at the final follow-up (p < 0.0005). A significant worsening was documented between 5years and the final follow-up (p < 0.0005). The Tegner score improved from the preoperative value of 2.0 (range 1-7) to 3.0 (range 1-7) at the final follow-up (p < 0.0005), although it remained lower as compared to the preinjury level of 4.0 (range 1-9) (p < 0.0005). Better results were documented in male and younger patients with smaller lesions, without the previous surgery, and without the previous ankle fractures or osteoarthritis. At the final follow-up, 85 patients considered their general health status "satisfactory" and 84 patients reported feeling "better" than the preoperative condition. Five patients were considered failures and underwent prosthetic ankle replacement or repeated the same surgery. This one-step technique showed to be an effective procedure for the treatment of OLT, providing a low failure rate and offering durable clinical improvements up to a minimum of 10years of follow-up. However, this technique demonstrated a small yet significant decrease over the years in terms of pain and function and poor results in terms of sports activity level. Level IV.

"Biofeedback-based return to sport": individualization through objective assessments.

Elite athletes are regularly exposed to high and repetitive mechanical stresses and impacts, resulting in high injury rates. The consequences of injury can range from time lost from training and competition to chronic physical and psychological burden, with no guarantee that the athlete will return to preinjury levels of sport activity and performance. Prominent predictors include load management and previous injury, highlighting the importance of the postinjury period for effective return to sport (RTS). Currently, there is conflicting information on how to choose and assess the best reentry strategy. Treating RTS as a continuum, with controlled progression of training load and complexity, seems to provide benefits in this process. Furthermore, objectivity has been identified as a critical factor in improving the effectiveness of RTS. We propose that assessments derived from biomechanical measurements in functional settings can provide the objectivity needed for regular biofeedback cycles. These cycles should aim to identify weaknesses, customize the load, and inform on the status of RTS progress. This approach emphasizes individualization as the primary determinant of RTS and provides a solid foundation for achieving it.

The Pressure Is Rising: Evaluation and Treatment of Chronic Exertional Compartment Syndrome.

Chronic exertional compartment syndrome is a condition that typically affects athletic/active individuals. Chronic exertional compartment syndrome predominantly affects the lower leg; however, there are cases involving the hand, forearm, foot, and thigh. The signs and symptoms of chronic exertional compartment syndrome are severe pain, tightness, cramping, muscle weakness, and paresthesias during participation in exercise. Dynamic intramuscular compartmental pressure (preexertion and postexertion) is the standard diagnostic test. Although other imaging modalities, such as radiography, ultrasound, and magnetic resonance imaging are typically incorporated to rule out other pathologies. In addition, these modalities are being utilized to limit invasiveness of the diagnostic experience. Initial care commonly involves conservative treatment, such as physical therapy, modifications of patient's exercise technique, foot orthoses, and various procedures over a period of 3 to 6 months. Recalcitrant cases may be referred for surgical intervention (fasciotomy), which has inconclusive head-to-head data with conservative management with regard to return to prior sport and specific activity level.
