RESUMEN
PURPOSE: Rheumatologists and orthopedic surgeons frequently collaborate on difficult decisions regarding perioperative management of immunosuppression in rheumatic disease patients, balancing risk of postoperative infection with risk of disease flares. Current evidence-based guidelines pertain specifically to arthroplasty, thus we sought to understand the trends and common practices regarding peri-arthroscopic use of immunosuppression. METHODS: Rheumatologists and sports medicine surgeons, from a variety of New York hospitals and serving a broad range of demographics, were surveyed on immunosuppressive medication management in rheumatic disease patients undergoing arthroscopic surgeries. Physicians' preferences were elicited regarding the use of common anti-rheumatic medications with the lower risk meniscectomies and the higher risk anterior cruciate ligament (ACL) reconstructions and allografts. Physicians were asked specifically about peri-arthroscopic use of conventional synthetic diseasemodifying antirheumatic drugs (csDMARDs), biologics, and Janus kinase (JAK) inhibitors. RESULTS: During the survey period, 25 rheumatologists and 19 sports medicine fellowship-trained orthopedic surgeons completed the questionnaire. For lower-risk arthroscopies, rheumatologists favored continuing various csDMARDs (72% to 100%), biologics (50% to 64%) and JAK inhibitors (57%), while a majority of surgeons concurred for all three drug classes (csDMARDs 63%; biologics 53%; and JAK inhibitors 58%). For higher-risk arthroscopies, most rheumatologists preferred that patients continue csDMARDs (63% to 100%) but fewer supported the use of biologics (28% to 39%) or JAK inhibitors (22%). Surgeons were more hesitant to endorse any class of immunosuppressive antirheumatic medications (22% to 27%) around these higher risk surgeries. The rheumatologists were most concerned about surgeries taking place too soon after the last dose of rituximab, recommending these higher risk surgeries not take place for 7.7 ± 8.8 weeks following the last infusion. CONCLUSION: For lower-risk arthroscopies, most rheumatologists but only about half of orthopedic surgeons preferred patients continuing csDMARDs. Approximately half of both groups preferred patients hold biologics and JAK inhibitors. In more involved arthroscopies, most rheumatologists but few orthopedists supported the continued use of csDMARDs, and the consensus was to hold all other immunosuppression when possible. While the duration medications were held perioperatively were somewhat reflective of the current guidelines for arthroplasty, there is a need for evidencebased guidelines specifically regarding peri-arthroscopy immunosuppression in rheumatic disease patients.

PURPOSE: Research surrounding the biomechanics and video analysis of anterior cruciate ligament (ACL) injuries at the professional level has emerged in recent years as a tool to screen athletes for potential biomechanical deficits. The purpose of this study was to analyze and discuss the most common mechanism, body position, and activity at the time of ACL injury among NBA players. METHODS: Anterior cruciate ligament injuries over 10 consecutive NBA seasons (2009-2010 to 2019-2020) were reviewed from publicly available sources. A 10-question survey was developed and utilized to analyze each video clip. These questions were divided into three categories: 1. contact mechanism, 2. activity at the time of injury, and 3. position of the involved lower extremity at the time of injury. Two reviewers analyzed the videos individually, and differing answers were resolved via consensus review, with a senior author arbitrating in the case of any discrepancies. RESULTS: Overall, 23 ACL ruptures were included. The most common injury mechanism was indirect contact with another player without knee contact (56.5%), and no patients had an ACL rupture as a result of direct knee contact with another player. The most common action at the time of injury was pivoting (47%), and the most common basketball action was dribbling (43.5%). Additionally, the vast majority of patients were injured while on offense (91.3%). The most common knee positions were early flexion (73.9%) and abduction (95.7%). The most common foot positions were abduction relative to the knee (82.6%), in eversion (73.9%), and dorsiflexion (56.5%). The most common hip position was early flexion (87%), and all hips were abducted (100%). CONCLUSION: Our study found that the majority of ACL ruptures occurred during offensive play and over half were secondary to contact with an opposing player (but without a direct blow to the injured knee), indicating that such perturbations may alter the kinematics of the players' movement. Additionally, a large majority of ACL injuries occurred while the hip was abducted with the knee in abduction relative to the hip and while the knee was in early flexion from 0° to 45°.

BACKGROUND: Shoulder arthroscopy and related complications like deep tissue infections have increased in the last several decades. Practice patterns have shown significant consensus among arthroscopic surgeons supporting intraoperative pre-incision antibiotic usage and against postoperative antibiotic usage. While there is consensus in practice, the absence of robust guidelines for postoperative antibiotic prophylaxis after shoulder arthroscopy warrants further research. PURPOSE: The purpose of this study was to determine the incidence of infection after shoulder arthroscopy in patients treated with or without postoperative prophylactic oral antibiotics. METHODS: A retrospective review of shoulder arthroscopies was performed at an outpatient surgery center over a 10-year period. The primary outcome measured was infection following a procedure, initial encounter, or subsequent encounter as defined by International Classification of Disease, Tenth Revision - Clinical Modification (ICD-10 CM) codes T81.4XXA or T814XXD. Incidence of infection was calculated for both cohorts and a chi-squared test was used to determine the statistical significance of betweengroup differences in infection incidence. A priori and post hoc power analyses were performed to determine the sample size required for statistical power and statistical power of the findings given the final study sample size, respectively. RESULTS: A total of 1,801 patients were included in the study. All patients received intraoperative pre-incision antibiotic prophylaxis. Prophylactic postoperative antibiotics were prescribed to 223 (12.38%) patients for varying durations following shoulder arthroscopy. There were zero cases of infection among patients who received antibiotics. There was one case (0.06%) of infection among the patients who did not receive antibiotics. This difference was not statistically significant (p = 0.71). Power analyses showed that the study was highly powered. CONCLUSIONS: Postoperative prophylactic oral antibiotics did not reduce the risk of infection in patients undergoing shoulder arthroscopy.

PURPOSE: The purpose of this study is to assess the association between sagittal tibial tuberosity-trochlear groove (sTT-TG) distance and patellofemoral chondral lesion size in patients undergoing cartilage restoration procedures. METHODS: A retrospective cohort analysis of patients who underwent an osteochondral allograft transplantation or matrix-induced autologous chondrocyte implantation in the patellofemoral compartment, from 2010 to 2020, were included if they had patellofemoral high-grade lesions, magnetic resonance imaging (MRI) and minimum 2-year follow-up. The preoperative sTT-TG distance was measured independently on axial T2-weighted MRI sequences by two authors, each at least two weeks apart. Intraoperative lesion size was reported according to operative report measurements by the attending surgeon. An interclass correlation coefficient (ICC) was calculated to assess intra- and inter-rater reliability, and categorical data analysis and linear regression models were used to assess the relationship between sTT-TG and lesion size. RESULTS: A total of 80 patients (50 females) with a mean age of 31.5 ± 10.4 years, body mass index of 27.0 ± 5.9 kg/m2 and follow-up of 61.5 ± 21.4 months were included. A total of 107 lesions were present: 63 patients with unipolar (patella = 41, trochlea = 22) and 22 with bipolar lesions. The mean MRI defect size was 1.6 ± 1.0 cm2 and the mean intraoperative defect size was 3.8 ± 2.4cm2. Intra- (ICC: 0.99,0.98) and inter-rater reliability (ICC: 0.96) were excellent for both MRI defect size and sTT-TG measurements. The mean sTT-TG was -4.8 ± 4.9 mm and was significantly inversely related to MRI defect size (-0.45, p < 0.01), intraoperative patellar lesion size (-0.32, p = 0.01), total lesion area (-0.22, p = 0.04), but not trochlear lesion size (-0.09, p = 0.56). Multivariable regression demonstrated a more negative sTT-TG remained an independent variable correlated with larger MRI-measured patellofemoral defect sizes and intraoperative patellar lesions. CONCLUSION: A more negative sTT-TG was an independent variable correlated with larger patellofemoral lesions in patients undergoing patellofemoral cartilage restoration. LEVEL OF EVIDENCE: Level III, Diagnostic.
RESUMEN
BACKGROUND: Open subpectoral biceps tenodesis (OSBT) with cortical button fixation has been shown to deliver acceptable results in the short and intermediate term for long head of the biceps (LHB) pathology with the benefit of smaller bone tunnel diameter and a reduced risk of postoperative humeral shaft fracture. The primary purpose of this study was to determine whether OSBT with cortical button fixation results in significant improvements in patient reported outcomes (PROs) from pre-operative to long-term final follow-up. METHODS: A retrospective analysis of patients who underwent OSBT with cortical button fixation at a single institution between the years of 2012 and 2014 was conducted and PROs were collected in the intermediate (> 2 years follow-up) and long term (> 9 years follow-up). PROs were measured pre-operatively, at intermediate follow-up, and at long-term follow-up using three validated questionnaires: American Shoulder and Elbow Surgeons (ASES) score, Disabilities of the Arm, Shoulder, and Hand (DASH) score, and Oxford Shoulder Score (OSS). Patients were additionally asked at final follow-up if they would undergo the same procedure again if they needed it. RESULTS: Twenty-nine (29) patients with a mean age of 51.16 ± 9.06 years at the time of surgery were included in the study at final follow-up. Mean final follow-up time was 10.2 ± 0.5 years (range: 9.2-11.1 years). All PROs (ASES, OSS, and DASH) demonstrated statistically significant improvements from pre-operative to final follow-up with p < 0.01 for each. The proportions of patients exceeding established values for minimum clinically important difference (MCID) were 96.55%, 93.10%, and 75.86% for ASES, OSS, and DASH respectively. Only one patient had required re-operation as of final follow-up. None experienced humeral fractures post-operatively. A significant majority (89.66%; p < 0.01) of patients reported that they would undergo the same procedure again if they needed it. Fifty-three (53) patients were included in the study at intermediate follow-up with a mean follow-up time of 3.5 ± 1.4 years (range: 2-5.3 years). There were no statistically significant differences in any of the PRO measures from intermediate to long-term follow-up. CONCLUSION: This study reported a minimum 9-year follow-up of patients undergoing OSBT with cortical button fixation for the management of LHBT pathology in the setting of concomitant shoulder procedures. All patients had significantly improved functional outcomes assessed with ASES, OSS, and DASH and no obvious differences in median group scores were found between patients assessed at intermediate (mean 3.5 years) and final (mean 10.2 years) follow-up. No infections, fractures, or fixation failures were reported.
RESUMEN
Purpose: To analyze the effects of 1 or more patient-reported allergies on clinical outcomes, in particular graft failure rate, and patient-reported outcomes (PROs) following osteochondral allograft transplantation (OCA) of the knee. Methods: Retrospective review of patients who underwent knee OCA from August 2010 to May 2021 with a minimum of 2-year follow-up. Patients were initially divided into 2 cohorts: those with at least 1 allergy and those without any allergies. Clinical outcomes assessed included graft failure, reoperation rates, deep vein thrombosis/pulmonary embolism, and manipulation under anesthesia/lysis of adhesions (MUA/LOA). PROs assessed, including the visual analog scale (VAS) for pain and satisfaction, the Knee injury and Osteoarthritis Outcome Score (KOOS), and return to sport rates, were compared. Results: In total, 285 patients were included with a mean clinical follow-up of 4.8 ± 2.0 years. The allergy cohort had a significantly higher rate of graft failure (P = .008). In a regression analysis controlling for confounding variables, graft failure remained significantly associated with the presence of medication allergies (odds ratio [OR], 3.631; 95% CI, 1.139-11.577; P = .029). Furthermore, an increasing number of allergies were associated with an increased rate of graft failure (OR, 1.644; 95% CI, 1.074-2.515; P = .022). There was no difference in rate of reoperation, complications, infection, and MUA/LOA. Of the 100 patients who completed PROs, there was no difference in VAS satisfaction, pain, and any of the KOOS outcome scores or return to sport. Conclusions: The presence of 1 or more patient-reported allergies was shown to be significantly associated with OCA graft failure. Furthermore, an increasing number of patient-reported allergies were associated with a higher rate of graft failure. However, there were no significant differences in VAS satisfaction or pain, KOOS symptom, quality of life, pain, or return to sport in patients with at least 1 patient-reported allergy and those without allergies. Level of Evidence: Level III, retrospective cohort study.
RESUMEN
PURPOSE: The purpose of this study was to determine whether significant differences exist when comparing posterior tibial slope (PTS) measured using increasing lengths of the tibia to determine the anatomical axis. METHODS: Patients with full-length weight-bearing tibial radiographs were retrospectively identified from 2014 to 2022 at a single institution. Patients were excluded if there was any previous history of lower extremity fracture or osteotomy. The anatomical axis of the tibia was determined using the full length of tibial radiographs, and the "reference PTS" was measured using this axis. Using the same radiograph, the PTS was measured using four different anatomical axes at standardized tibial lengths. While the center of the proximal circle remained constant at 5-cm below the tibial plateau, the center of the distal circle was drawn at four points: a) overlapping circles; b) 10-cm distal to the tibial plateau; c) 15-cm distal to the tibial plateau; d) half the length of the tibia, measured from the tibial plateau to the tibial plafond. Bivariate correlation and frequency distribution analysis (measurements >2-degrees from reference PTS) were performed between the reference PTS and PTS measured at each of the four other lengths. RESULTS: A total of 154 patients (39.8 ± 17.4 years old, 44.2% male) were included in the final analysis. Measurements at each of the four tibial lengths were all significantly different from the reference PTS (p < 0.001). The correlation strength improved with increasing tibial length (overlapping: R = 0.681, 10-cm: R = 0.821, 15-cm: R = 0.937, and half-tibia: R = 0.963). The number of PTS measurements >2-degree absolute difference from the reference PTS decreased with increasing tibial length (overlapping: 40.3%, 10-cm: 24.0%, 15-cm: 26.0%, and half-tibia: 18.8%). CONCLUSION: Assessment of PTS is dependent on the length of the tibia utilized to obtain the anatomical axis. Accuracy and precision of PTS measurements improved with increasing length of tibia used to determine the anatomical axis. STUDY DESIGN: Case series.

PURPOSE: To assess clinical outcomes and return to sport (RTS) rates among patients who undergo osteochondral allograft (OCA) transplantation and autologous chondrocyte implantation (ACI) or matrix-induced autologous chondrocyte implantation (MACI), for patellofemoral articular cartilage defects. METHODS: A retrospective review of patients who underwent an OCA or ACI/MACI from 2010 to 2020 was conducted. Patient-reported outcomes collected included visual analog scale for pain/satisfaction, Knee Injury and Osteoarthritis Outcome Score (KOOS), and RTS. The percentage of patients that met the patient acceptable symptom state for KOOS was recorded. Logistic regression was used to identify predictors of worse outcomes. RESULTS: A total of 95 patients were included (78% follow-up) with ACI or MACI performed in 55 cases (57.9%) and OCA in 40 (42.1%). A tibial tubercle osteotomy was the most common concomitant procedure for OCA (66%) and ACI/MACI (98%). Overall, KOOS pain was significantly poorer in OCA than ACI/MACI (74.7, 95% confidence interval 68.1-81.1 vs 83.6, 95% confidence interval 81.3, 88.4, P = .012), whereas the remaining KOOS subscores were nonsignificantly different (all P > .05). Overall, RTS rate was 54%, with no significant difference in return between OCA or ACI/MACI (52% vs 58%, P = .738). There were 26 (27%) reoperations and 5 (5%) graft failures in the entire group. Increasing age was associated with lower satisfaction in OCA and poorer outcomes in ACI/MACI, whereas larger lesion area was associated with lower satisfaction and poorer outcomes in ACI/MACI. CONCLUSIONS: Clinical and functional outcomes were similar in patients who underwent OCA or ACI/MACI for patellofemoral articular cartilage defects at a mean follow-up of 5 years. Patients who received OCA had a greater proportion of degenerative cartilage lesions and, among those with trochlear lesions, reported greater pain at final follow-up than their ACI/MACI counterparts. Overall, increasing age and a larger lesion size were associated with worse patient-reported outcomes. LEVEL OF EVIDENCE: Level III, retrospective cohort study.
RESUMEN
PURPOSE: To evaluate long-term outcomes of patients treated with posterior medial meniscal root tear (PMMRT) repair through assessment of functional outcome scores and to identify patient surgical and magnetic resonance imaging (MRI) characteristics associated with improved outcomes. METHODS: This was a single-centre, retrospective study evaluating patients who had undergone a PMMR repair using a transtibial suture pullout technique with two locking cinch sutures. This was performed as a follow-up to previously published 2-year and 5-year outcome studies, using the same cohort. All patients from the prior short-term and midterm studies were invited to participate. Patient-reported outcome (PROs) scores, including the International Knee Documentation Committee (IKDC) and Lysholm scores, were collected. Previously collected demographic data were updated based on review of the electronic medical record. Patient outcomes were assessed preoperatively, as well as at 2-year, 5-year and 8-year postoperatively. MRI outcome measurements were assessed at 2-year and 5-year follow-ups. All statistical analysis was performed using SPSS version 26. RESULTS: Seventeen patients of the original 18 patients (94.4%) were included in the final analysis. Additionally, three patients who had additional ipsilateral surgery were excluded from the analysis of PROs. The IKDC score significantly increased from 44.7 ± 11.6 at preoperative baseline to 71.2 ± 21.3 at 8-year post-operation (p = 0.001). There were no significant differences in IKDC score between 2-year and 8-year follow-ups (p = n.s.) or 5-year and 8-year follow-ups (p = n.s.). The Lysholm score significantly increased from 49.6 ± 7.3 at preoperative baseline to 76.4 ± 17.2 at 8-year follow-up (p < 0.001). There was no significant difference in Lysholm scores between 2-year and 8-year follow-ups (p = n.s.) or 5-year and 8-year follow-ups (p = n.s.). A linear regression analysis found that 5-year IKDC scores were significantly correlated with 8-year IKDC scores (ß = 0.681, p = 0.038). At 8-year follow-up, four (23.5%) patients required additional procedures on their operative knee (one total knee arthroplasty conversion). CONCLUSION: Patients treated with repair of PMMRT had maintenance of clinical outcome improvements at long-term follow-up despite worsening MRI outcomes at short-term and medium-term follow-ups. While a high proportion of patients required additional procedures on their operative knee at 8-year follow-up, few of these patient's additional procedures were related to failure of their primary surgery. Providers and patients may expect durable clinical outcomes following the repair of PMMRT, irrespective of radiographic appearance. LEVEL OF EVIDENCE: Level IV.
RESUMEN
PURPOSE: The purpose of this study was to compare the clinical outcomes of patients with patellofemoral osteoar-thritis (PFOA) treated non-operatively with those treated operatively with an unloading anteromedialization tibial tubercle osteotomy (TTO). METHODS: A retrospective chart review was performed to identify patients with isolated PFOA who were either managed non-operatively or surgically with a TTO and who had a minimum follow-up of 2 years. Patients were surveyed with the visual analog scale (VAS) for pain, Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS-JR), Anterior Knee Pain scale (Kujala), and Tegner Activity scale. Statistical analysis included two-sample t-testing, one-way ANOVA, and bivariate analysis. RESULTS: The clinical outcomes of 49 non-operatively managed patients (mean age: 52.7 ± 11.3 years; mean follow-up: 1.7 ± 1.0 years) and 35 operatively managed patients (mean age: 31.8 ± 9.4 years; mean follow-up: 3.5 ± 1.7 years) were assessed. The mean VAS improved sig-nificantly in both groups [6.12 to 4.22 (non-operative), p < 0.0001; 6.94 to 2.45 (TTO); p < 0.0001], with operatively treated patients having significantly lower postoperative pain than non-operatively managed patients at the time of final follow-up [2.45 (TTO) vs. 4.22 (non-operative), p < 0.001]. The mean KOOS-JR score was significantly greater in the operative group at time of final follow-up [78.7 ± 11.6 (TTO) vs. 71.7 ± 17.8 (non-operative), p = 0.035]. There was no significant difference in Kujala or Tegner scores between the treatment groups. Additionally, there was no sig-nificant relationship between the number of intra-articular injections, duration of NSAID use, and number of physical therapy sessions on clinical outcomes in the non-operatively treated group (p > 0.05). CONCLUSIONS: An unloading anteromedialization TTO provides significantly better pain relief and restoration of function compared to non-operative management in the treatment of symptomatic PFOA.

OBJECTIVE: The purpose of this study was to compare the short-term clinical outcomes of matrix-induced autologous chondrocyte implantation (MACI) to those seen following traditional autologous chondrocyte implantation (ACI) in the management of symptomatic cartilage lesions of the knee. METHODS: This was a retrospective cohort study of patients who underwent either ACI or MACI from January 2011 to March 2018. Patients with a minimum postoperative follow-up of 18 months were contacted. Demographic information, intraoperative findings, and patient-reported functional outcomes scores were collected. Comparisons were made between the two cell-based cartilage repair techniques. RESULTS: Fifty-six patients were included in the study (39 ACI, 17 MACI). Visual analog scale (VAS) for pain scores improved significantly in both groups, with MACI patients demonstrating significantly lower postoperative pain scores compared to those treated with ACI. In the ACI group, there was a decrease in the Tegner Activity score compared to the preoperative baseline, while no significant difference was seen between pre- and postoperative activity levels in the MACI group. Patients were generally satisfied with the outcome of their procedures, and there was no significant difference in satisfaction between groups. No patients re-quired additional surgery during the follow-up period. CONCLUSION: Both ACI and MACI demonstrated good short-term postoperative clinical results with improved pain and activity levels compared to the preoperative baseline. Patients treated with the MACI technique demonstrated greater reductions in pain scores compared to ACI, and while ACI resulted in a decrease in levels of postoperative activity, activity levels for MACI remained stable.

Background: Elbow ulnar collateral ligament (UCL) reconstruction (UCLR) is the gold standard for operative treatment of UCL tears, with renewed interest in UCL repairs. Purpose: To (1) assess trends in rates of UCLR and UCL repair and (2) identify predictors of complications by demographic, socioeconomic, or surgical center volume factors. Study Design: Descriptive epidemiology study. Methods: Patients who underwent UCLR or UCL repair at New York State health care facilities between 2010 and 2019 were retrospectively identified; concomitant ulnar nerve procedures among the cohort were also identified. Surgical center volumes were classified as low (<99th percentile) or high (≥99th percentile). Patient information, neighborhood socioeconomic status quantified using the Area Deprivation Index, and complications within 90 days were recorded. Poisson regression analysis was used to compare trends in UCLR versus UCL repair. Multivariable regression was used to determine whether center volume, demographic, or socioeconomic variables were independent predictors of complications. Results: A total of 1448 UCL surgeries were performed, with 388 (26.8%) concomitant ulnar nerve procedures. UCLR (1084 procedures; 74.9%) was performed more commonly than UCL repair (364 procedures; 25.1%), with patients undergoing UCL repair more likely to be older, female, and not privately ensured and having undergone a concomitant ulnar nerve procedure (all P < .001). With each year, there was an increased incidence rate ratio for UCL repair versus UCLR (ß = 1.12 [95% CI, 1.02-1.23]; P = .022). The authors identified 2 high-volume centers (720 UCL procedures; 49.7%) and 131 low-volume centers (728 UCL procedures; 50.3%). Patients undergoing UCL procedures at high-volume centers were more likely to be younger and male and receive workers' compensation (all P < .001). UCL repair and ulnar nerve-related procedures were both more commonly performed at low-volume centers (P < .001). There were no significant differences in 3-month infection, ulnar neuritis, instability, arthrofibrosis, heterotopic ossification, or all-cause complication rates between low- and high-volume centers. The only significant predictor for all-cause complication was Medicaid insurance (OR, 2.91 [95% CI, 1.20-6.33]; P = .011). Conclusion: A rising incidence of UCL repair compared with UCLR was found in New York State, especially among female patients, older patients, and nonprivate payers. There were no differences in 3-month complication rates between high- and low-volume centers, and Medicaid insurance status was a predictor for overall complications within 90 days of operation.
RESUMEN
PURPOSE: The purpose of this study was to identify sex differences in postoperative outcomes and return-to-sport rates after fasciotomy for treatment of chronic exertional compartment syndrome (CECS) of the lower leg. It was hypothesised that male CECS patients would have a higher rate of return to sport than female CECS patients. METHODS: A retrospective cohort study was conducted involving patients who underwent primary fasciotomy of one to four leg compartments for treatment of CECS at a single centre from 2010 to 2020. Each affected leg was treated as a separate subject. Postoperative outcomes included CECS pain frequency and severity, return to sport and Tegner activity level. Multivariable regression was used to determine if sex was an independent predictor of outcomes after adjusting for demographic and clinical covariates. p < 0.05 were considered significant. RESULTS: Eighty-one legs (44 M, 37 F) of 47 unique patients (34 of whom had bilateral symptoms) were included with a mean follow-up time of 51.5 ± 31.4 months. Male subjects were older (p < 0.001) and had higher body mass index (p < 0.001) compared to female subjects. Most subjects (84.0%) underwent two- or four-compartment fasciotomies. Female sex was found to be predictive of lower overall postoperative pain severity (p = 0.007), higher odds of return to sport (p = 0.04) and higher postoperative Tegner score (p = 0.005). However, female sex was not predictive of postoperative pain frequency, odds of reoperation or odds of return to sport to at least the presymptomatic level (all p < 0.05). CONCLUSION: Female sex is independently predictive of reduced overall pain severity, higher odds of return to sport and higher postoperative improvement in Tegner score following fasciotomy for treatment of lower-limb CECS. LEVEL OF EVIDENCE: III.
RESUMEN
PURPOSE: To establish consensus statements on the diagnosis, nonoperative management, and labral repair for posterior shoulder instability. METHODS: A consensus process on the treatment of posterior shoulder instability was conducted, with 71 shoulder/sports surgeons from 12 countries participating on the basis of their level of expertise in the field. Experts were assigned to 1 of 6 working groups defined by specific subtopics within posterior shoulder instability. Consensus was defined as achieving 80% to 89% agreement, whereas strong consensus was defined as 90% to 99% agreement, and unanimous consensus was indicated by 100% agreement with a proposed statement. RESULTS: Unanimous agreement was reached on the indications for nonoperative management and labral repair, which include whether patients had primary or recurrent instability, with symptoms/functional limitations, and whether there was other underlying pathology, or patient's preference to avoid or delay surgery. In addition, there was unanimous agreement that recurrence rates can be diminished by attention to detail, appropriate indication and assessment of risk factors, recognition of abnormalities in glenohumeral morphology, careful capsulolabral debridement and reattachment, small anchors with inferior placement and multiple fixation points that create a bumper with the labrum, treatment of concomitant pathologies, and a well-defined rehabilitation protocol with strict postoperative immobilization. CONCLUSIONS: The study group achieved strong or unanimous consensus on 63% of statements related to the diagnosis, nonoperative treatment, and labrum repair for posterior shoulder instability. The statements that achieved unanimous consensus were the relative indications for nonoperative management, and the relative indications for labral repair, as well as the steps to minimize complications for labral repair. There was no consensus on whether an arthrogram is needed when performing advanced imaging, the role of corticosteroids/orthobiologics in nonoperative management, whether a posteroinferior portal is required. LEVEL OF EVIDENCE: Level V, expert opinion.
RESUMEN
OBJECTIVES: The purpose of this study was to compare clinical outcomes of medial quadriceps tendon-femoral ligament reconstruction (MQTFLR) and medial patellofemoral ligament reconstruction (MPFLR) among patients with recurrent lateral patellar instability. METHODS: A retrospective matched-cohort study was conducted involving patients who underwent MQTFLR or MPFLR with or without tibial tubercle osteotomy (TTO) from 2019 to 2021. Subjects were matched 1:1 on age, concomitant osteochondral allograft (OCA), concomitant TTO, and follow-up time. Measured outcomes included 90-day complications, Visual Analog Scale (VAS) knee pain, return to sport/work, Kujala score, Tegner score, and MPFL-Return to Sport after Injury (MPFL-RSI) score. Outcomes were compared between groups using Mann-Whitney U-test for continuous variables and Fisher's exact test for categorical variables. P-values <0.05 were considered significant. RESULTS: Ten MQTFLR patients (mean age 28.7 years, 80% female, mean follow-up 19.7 months) and ten MPFLR patients (mean age 29.1 years, 90% female, mean follow-up 28.3 months) were included in the study. One MQTFLR patient (10%) and three MPFLR patients (30%) underwent reoperation for postoperative arthrofibrosis. Postoperative VAS resting pain was not significantly different between the groups (MQTFLR mean 1.1, MPFLR mean 0.6, p â= â0.31). There were no significant differences in rates of recurrent subluxations (MQTFLR 20%, MPFLR 0%, p â= â0.47), return to sport (MQTFLR 50%, MPFLR 75%, p â= â0.61), return to work (MQTFLR 100%, MPFLR 88%, p â= â1.00), or MPFL-RSI pass rate (MQTFLR 75% vs. MPFLR 38%, p â= â0.31). CONCLUSION: There were no significant differences in knee pain and function, return to work, and rates of recurrent patellar instability between patients who underwent MQTFLR versus MPFLR, though these results should be interpreted with caution given the small sample size and potential selection bias. LEVEL OF EVIDENCE: III.

Recurrent patellar instability can significantly impact patients' quality of life and function. A large amount of research on patellar instability has been conducted in the past two decades, and a number of traditionally held principles of treatment have been challenged. This review addresses three current concepts and controversies in the treatment of patellar instability, specifically what factors lead to an increased tibial tubercle-trochlear groove distance and how to address them, when to add a tibial tubercle osteotomy to a medial patellofemoral ligament (MPFL) reconstruction, and which medial patellar stabilizers should be reconstructed. Based on current evidence, there are a few recommendations that can be made at this time. While trochleoplasty does have concerns with regard to reproducibility and complication risk, surgeons should consider this technique especially in cases with Dejour D trochlear dysplasia given high failure rates with other techniques. When evaluating whether to concomitantly perform a tibial tubercle osteotomy (TTO) with a MPFL, a TTO does appear to improve outcomes in the presence of maltracking or a positive J sign even with a tibial tuberosity-trochlear grove distance (TT-TG) of 18 to 20 mm, whereas patients without maltracking with a TT-TG of up to 25 mm may do well with an isolated MPFL reconstruction. Lastly, while MPFL reconstruction continues to have the most robust data supporting favorable outcomes, a number of biomechanical studies and short-term clinical studies have suggested promising results with medial quadriceps tendon femoral ligament and hybrid techniques.

This review highlights the expanding use of knee-based osteotomies in the treatment of knee joint malalignment and joint preservation. Planning and outcomes of traditional high tibial osteotomies and distal femoral osteotomies are discussed in addition to some of the challenges encountered with these procedures. Lastly, the role of patient-specific instrumentation and three-dimensional guided templating in performing osteotomies is discussed with respect to procedures that involve biplanar corrections and those performed in combination with other joint preservation procedures.

Purpose: Arthroscopic Bankart repair (ABR) may be more effective than nonoperative management for patients with anterior shoulder instability following first-time dislocation. The purpose of the study was to determine the most cost-effective treatment strategy by evaluating the incremental cost-effectiveness ratio (ICER) for ABR versus nonoperative treatment. Methods: This cost-effectiveness study utilized a Markov decision chain and Monte Carlo simulation. Probabilities, health utility values, and outcome data regarding ABR and nonoperative management of first-time shoulder instability derived from level I/II evidence. Costs were tabulated from Centers for Medicaid & Medicare Services. Probabilistic sensitivity analysis was performed using >100,000 repetitions of the Monte Carlo simulation. A willingness-to-pay (WTP) threshold was set at $50,000. Results: The expected cost for operative management higher than nonoperative management ($32,765 vs $29,343). However, ABR (5.48 quality-adjusted life years (QALYs)) was the more effective treatment strategy compared to nonoperative management (4.61 QALYs). The ICER for ABR was $3943. Probabilistic sensitivity analysis showed that ABR was the most cost-effective strategy in 100% of simulations. Discussion: ABR is more cost-effective than nonoperative management for first-time anterior shoulder dislocation. The threshold analysis demonstrated that when accounting for WTP, ABR was found to be the more cost-effective strategy.
RESUMEN
Background: Cannabidiol (CBD) has been shown recently to positively affect patient pain and satisfaction immediately after arthroscopic rotator cuff repair (ARCR). However, it is unclear whether the addition of CBD to a perioperative regimen could affect postoperative outcomes. Purpose: To evaluate patient-reported outcomes among patients who underwent ARCR and received buccally absorbed CBD or an identical placebo for early postoperative pain management at 1-year follow-up. Study Design: Randomized controlled trial; Level of evidence, 2. Methods: Eligible patients had previously participated in a multicenter, placebo-controlled, randomized, double-blinded trial that evaluated the analgesic effects of CBD in the immediate postoperative period after ARCR. The experimental group received 25 mg of CBD 3 times/day if <80 kg and 50 mg of CBD 3 times/day if >80 kg for 14 days, with the control group receiving an identical placebo. The following outcomes were assessed at minimum 1-year follow-up: visual analog scale (VAS) for pain, American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE), and patient satisfaction. The rates of achievement of the Patient Acceptable Symptom State (PASS) were compared based on ASES at latest follow-up. Continuous and categorical variables were compared with the Mann-Whitney U test and Fisher exact test, respectively. Results: Follow-up was obtained from 83 of 99 patients (83.8%) who completed the original trial. There were no significant differences between the CBD and control groups with respect to age, sex, body mass index, rate of concomitant procedures, or number of anchors used intraoperatively. At 1-year follow-up, there were no significant differences between the CBD and control groups in VAS pain (0.8 vs 1.2, P = .38), ASES (93.0 vs 91.1, P = .71), SANE (87.6 vs 90.1, P = .24), or satisfaction (97.4 vs 95.4, P = .41). A majority of patients achieved the PASS (81.0% [CBD] vs 77.5% [control]; P = .79). Conclusion: Perioperative use of CBD for pain control among patients undergoing ARCR did not result in any significant deficits in pain, satisfaction, or patient-reported outcomes at 1-year postoperatively compared with a placebo control group. These findings suggest that CBD can be considered in a postoperative multimodal pain management regimen without detrimental effects on outcome. Registration: NCT04672252 (ClinicalTrials.gov identifier).
RESUMEN
BACKGROUND: Bone marrow stimulation (BMS) has been proposed to augment healing at the time of arthroscopic rotator cuff repair (ARCR) by creating several bone marrow vents in the footprint of the rotator cuff, allowing mesenchymal stem cells, platelets, and growth factors to cover the area as a "crimson duvet." PURPOSE: To perform a meta-analysis of randomized controlled trials (RCTs) to compare the outcomes after BMS and a control for those undergoing ARCR. STUDY DESIGN: Meta-analysis; Level of evidence, 1. METHODS: A literature search of 3 databases was performed based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. RCTs comparing BMS and a control for ARCR were included. Clinical outcomes were compared, and a P value <.05 was considered to be statistically significant. RESULTS: A total of 7 RCTs with 576 patients were included. Overall, 18.8% of patients treated with BMS and 21.0% of patients treated with a control had a retear (I2 = 43%; P = .61). With BMS, the mean Constant score was 88.2, and with the control, the mean Constant score was 86.7 (P = .12). Additionally, there was no significant difference in the American Shoulder and Elbow Surgeons score (94.3 vs 93.2, respectively; P = .31) or visual analog scale score (0.9 vs 0.9, respectively; P = .89). CONCLUSION: The level 1 evidence in the literature did not support BMS as a modality to improve retear rates or clinical outcomes after ARCR.
