RESUMEN
SLAP tears are a common cause of shoulder pain in overhead athletes. The benefits of in-office nano-arthroscopy include the ability to diagnosis and treat biceps tendinopathy, quicker patient recovery, reduced health care costs, and improved patient satisfaction. This technique can be particularly advantageous in the management of SLAP tears given that magnetic resonance imaging has poor sensitivity without the use of an invasive arthrogram. The purpose of this technical report is to describe our technique for performing in-office nano-arthroscopy for SLAP tears with special consideration of the technique for obtaining adequate local anesthesia, proper indications, and adequate visualization, as well as the advantages of performing these procedures in the office rather than the operating room.
RESUMEN
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
BACKGROUND: Spinopelvic parameters, including pelvic tilt (PT), sacral slope (SS), and pelvic incidence, have been developed to characterize the relationship between lumbar spine and hip motion, but a paucity of literature is available characterizing differences in spinopelvic parameters among patients with femoroacetabular impingement syndrome (FAIS) versus patients without FAIS, as well as the effect of these parameters on outcomes of arthroscopic treatment of FAIS. PURPOSE: To (1) identify differences in spinopelvic parameters between patients with FAIS versus controls without FAIS; (2) identify associations between spinopelvic parameters and preoperative patient-reported outcomes (PROs); and (3) identify differences in PROs between patients with stiff spines (standing-sitting ΔSS ≤10°) versus those without. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: The study enrolled patients ≥18 years of age who underwent primary hip arthroscopy for treatment of FAIS with cam, pincer, or mixed (cam and pincer) morphology. Participants underwent preoperative standing-sitting imaging with a low-dose 3-dimensional radiography system and were matched on age and body mass index (BMI) to controls without FAIS who also underwent EOS imaging. Spinopelvic parameters measured on EOS films were compared between the FAIS and control groups. Patients with FAIS completed the modified Harris Hip Score (mHHS) and Non-Arthritic Hip Score (NAHS) before surgery and at 1-year follow-up. Outcome scores were compared between patients with stiff spines versus those without. Associations between spinopelvic parameters and baseline outcome scores were assessed with Pearson correlations. Continuous variables were compared with Student t test and/or Mann-Whitney U test, and categorical variables were compared with Fisher exact test. RESULTS: A total of 50 patients with FAIS (26 men; 24 women; mean age, 36.1 ± 10.7 years; mean BMI, 25.6 ± 4.2) were matched to 30 controls without FAIS (13 men; 17 women; mean age, 36.6 ± 9.5 years; mean BMI, 26.7 ± 3.6). Age, sex, and BMI were not significantly different between the FAIS and control groups (P > .05). Standing PT was not significantly different between stiff and non-stiff cohorts (P = .73), but sitting PT in the FAIS group was more than double that of the control group (36.5° vs 15.0°; P < .001). Incidence of stiff spine was significantly higher in the FAIS group (62.0% vs 3.3%; P < .001). Among FAIS patients, those with stiff spines had a significantly higher prevalence of cam impingement, whereas those with non-stiff spines had a higher prevalence of mixed impingement (P = .04). No significant differences were seen in preoperative mHHS or NAHS scores or pre- to postoperative improvement in scores between FAIS patients with stiff spines versus those without (P > .05), but a greater sitting SS was found to be positively correlated with a higher baseline mHHS (r = 0.36; P = .02). CONCLUSION: Patients with FAIS were more likely to have a stiff spine (standing-sitting ΔSS ≤10°) compared with control participants without FAIS. FAIS patients with stiff spines were more likely to have isolated cam morphology than patient without stiff spines. Although sitting SS was positively correlated with baseline mHHS, no significant differences were seen in 1-year postoperative outcomes between FAIS patients with versus without stiff spine.

A 42-year-old male with no past medical history presented to an emergency room with increasing pain and swelling of his left lower extremity over 48 hours with no preceding trauma. A computed tomography scan demonstrated a hematoma (20 cm × 4 cm × 10 cm) present within the gastrocnemius-soleus complex. Acute compartment syndrome (ACS) was diagnosed clinically, confirmed intraoperatively with an arterial line transducer, and treated with emergent fasciotomy. Extensive workup found no evidence of coagulopathy or source of bleeding. This case presents a patient with ACS secondary to an atraumatic gastrocnemius hematoma discovered in the emergency room with no history of coagulopathies or anticoagulation.
RESUMEN
PURPOSE: The purpose of this study was to investigate the incidence and anatomic distribution of meniscus injury in patients who have sustained acute ACL injuries with and without concomitant Segond fracture. We hypothesized that patients who have sustained a torn ACL with a concomitant Segond fracture would have a higher incidence of lateral meniscal injuries than patients with an isolated ACL injury. METHODS: Patients who underwent ACL reconstruction from 2012 to 2022 were retrospectively reviewed. Segond fractures were identified on knee radiographs. Inclusion criteria were age 18-40, injury during sports activity, and reconstruction within 90 days of injury. Sports activity, anatomic location of meniscus injury, and meniscus treatment were documented. Multivariable regression was used to identify predictors of meniscus injury/treatment. RESULTS: There were 25 of 603 (4.1%) patients who had an ACL tear with concomitant Segond fracture. The incidence of lateral meniscus injury in the Segond group (72%) was significantly higher than in the non-Segond cohort (49%; p = 0.024). A significantly smaller proportion of medial meniscus injuries among patients with Segond fractures were repaired (23.1%) compared to the non-Segond group (54.2%; p = 0.043). Multivariate analysis found patients with Segond fractures to have increased odds of lateral meniscus injury (OR 2.68; [1.09, 6.60], p = 0.032) and were less likely to have medial meniscus injuries repaired (OR 0.35; [0.15, 0.81], p = 0.014). Additionally, males had increased odds of lateral meniscus injury (OR 1.54; [1.08 - 2.91], p = 0.017), which were more likely to require repair (OR 1.48; [1.02, 2.14], p = 0.038). CONCLUSIONS: Among acute ACL injuries, the incidence of lateral meniscus injury is greater among patients with Segond fractures. Patients with Segond fracture were less likely to undergo repair of medial meniscal injuries.

The gold standard for surgical treatment of anterior cruciate ligament (ACL) injuries is reconstruction. There are a variety of graft options, from autograft to allograft, using bone-patellar tendon-bone (BTB), hamstrings, quadriceps, or Achilles, and, in the case of a multiligamentous knee injury (MLKI), allograft may be preferred to decrease operative time and graft harvest morbidity. The BioBrace (ConMed, New Haven, CT) is a bioinductive collagen scaffold designed to provide an environment for soft tissue remodeling with time zero biomechanical support and can be used to augment graft reconstructions in the case of concerns for allograft strength, healing, or width. The purpose of this Technical Note is to describe the technique for performing an ACL reconstruction with BioBrace-augmented allograft in the setting of a MLKI, with special consideration for 2 methods of graft preparation (BTB and soft tissue).
RESUMEN
BACKGROUND: Massive irreparable rotator cuff tears (MIRCTs) remain a challenging treatment paradigm, particularly for nonelderly patients without pseudoparalysis or arthritis. PURPOSE: To use a network meta-analysis to analyze comparative studies of surgical treatment options for MIRCTs in patients <70 years of age for several patient-reported outcomes, range of motion (ROM), and acromiohumeral distance (AHD). STUDY DESIGN: Network meta-analysis of comparative studies; Level of evidence, 3. METHODS: A systematic review of the literature, using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, of the MEDLINE, Embase, and Cochrane Library databases was conducted from 2017 to 2022. Inclusion criteria were (1) clinical comparative studies of MIRCTs (with several study-specific criteria); (2) ≥1 outcome of interest reported on, with standard deviations; (3) minimum 1-year follow-up; and (4) mean age of <70 years for both cohorts, without arthritis or pseudoparalysis. There were 8 treatment arms compared. Outcomes of interest were the American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley score, visual analog scale for pain, AHD, and forward flexion and external rotation ROM. A frequentist approach to network meta-analysis with a random-effects model was performed using the netmeta package Version 0.9-6 in R. RESULTS: A total of 23 studies met the inclusion criteria, with 1178 patients included in the network meta-analysis. There was a mean weighted age of 62.8 years, 568 (48.2%) men, with a mean follow-up of 28.9 months. There were no significant differences between groups in regard to sex (P = .732) or age (P = .469). For the ASES score, InSpace balloon arthroplasty (mean difference [MD], 12.34; 95% CI, 2.18 to 22.50; P = .017), arthroscopic bridging graft (aBG) (MD, 7.07; 95% CI, 0.28 to 13.85; P = .041), and long head of biceps augmented superior capsular reconstruction (BSCR) (MD, 5.16; 95% CI, 1.10 to 9.22; P = .013) resulted in the highest P-scores. For the Constant-Murley score, debridement (MD, 21.03; 95% CI, 8.98 to 33.08; P < .001) and aBG (MD, 6.97; 95% CI, 1.88 to 12.05; P = .007) resulted in the highest P-scores. For AHD, BSCR resulted in the highest P-score (MD, 1.46; 95% CI, 0.45 to 2.48; P = .005). For forward flexion ROM, debridement (MD, 45.77; 95% CI, 25.41 to 66.13; P < .001) resulted in the highest P-score, while RSA resulted in the lowest P-score (MD, -16.70; 95% CI, -31.20 to -2.20; P = .024). CONCLUSION: For patients <70 years with MIRCT without significant arthritis or pseudoparalysis, it appears that graft interposition repair techniques, superior capsular reconstruction using the long head of the biceps tendon, arthroscopic debridement, and balloon arthroplasty provide superiority in various outcome domains, while RSA provides the least benefit in forward flexion.
RESUMEN
An important domain of artificial intelligence is deep learning, which comprises computed vision tasks used for recognizing complex patterns in orthopaedic imaging, thus automating the identification of pathology. Purported benefits include an expedited clinical workflow; improved performance and consistency in diagnostic tasks; decreased time allocation burden; augmentation of diagnostic performance, decreased inter-reader discrepancies in measurements and diagnosis as a function of reducing subjectivity in the setting of differences in imaging quality, resolution, penetrance, or orientation; and the ability to function autonomously without rest (unlike human observers). Detection may include the presence or absence of an entity or identification of a specific landmark. Within the field of musculoskeletal health, such capabilities have been shown across a wide range of tasks such as detecting the presence or absence of a rotator cuff tear or automatically identifying the center of the hip joint. The clinical relevance and success of these research endeavors have led to a plethora of novel algorithms. However, few of these algorithms have been externally validated, and evidence remains inconclusive as to whether they provide a diagnostic benefit when compared with the current, human gold standard.

Stem cell therapies have become widely popular in orthopaedic surgery, with a recent interest in adipose-derived therapeutics. Adipose-derived mesenchymal signaling cells (ADSCs) and micronized adipose tissue (MAT) are unique therapies derived from different processing methods. Characterizing the most influential studies in lipoaspirate research can help clarify controversies in definitions, identify core literature, and further collective knowledge for educational purposes. The Science Citation Index Expanded subsection of the Web of Science Core Collection was systematically searched to identify the top 50 most cited publications (based on citation/year) on orthopaedic ADSCs or MAT research. Publication and study characteristics were extracted and reported using descriptive statistics. Level of evidence was assessed for applicable studies, and Spearman correlations were calculated to assess the relationship between citation data and level of evidence. The top 50 articles were published between the years 2003 and 2020, with 78% published in the year 2010 or later. The mean number of citations was 103.1 ± 81.1. The mean citation rate was 12.4 ± 6.0 citations per year. Of the 21 studies for which level of evidence was assessed, the majority were level III (10, 47.6%). The single study design most common among the top 50 cited articles was in vitro basic science studies (17 studies, 34%). Twenty-nine articles (58%) were classified as basic science or translational. Application to treat knee osteoarthritis was the most common focus of studies (14 studies, 28%), followed by in vitro analysis of growth factor and cell signaling markers (11 studies, 22%). No correlation was found between rank, citation rate, or year of publication and level of evidence. This study provides a current landscape on the most cited articles in lipoaspirates in orthopaedic surgery. With the expansion of ADSCs and MAT in the past two decades, this study provides the first historical landmark of the literature and a launching point for future research. Studies should explicitly state their processing methodology and whether their study investigates ADSCs or MAT to avoid misinformation.

PURPOSE: To evaluate the impact of age, body mass index (BMI), and symptom duration on 5-year clinical outcomes among females following primary hip arthroscopy for femoroacetabular impingement syndrome (FAIS). METHODS: We conducted a retrospective review of a prospectively collected database of hip arthroscopy patients with a minimum 5-year follow-up. Patients were stratified by age (<30, 30-45, ≥45 years), BMI (<25.0, 25.0-29.9, ≥30.0), and preoperative symptom duration (<1 vs ≥1 year). Patient-reported outcomes were assessed using the modified Harris Hip Score (mHHS) and Non-Arthritic Hip Score (NAHS). Pre- to postoperative improvement in mHHS and NAHS was compared between groups using the Mann-Whitney U test or Kruskal-Wallis test. Hip survivorship rates and minimum clinically important difference (MCID) achievement rates were compared with Fisher exact test. Predictors of outcomes were identified using multivariable linear and logistic regression. P values <.05 were considered significant. RESULTS: In total, 103 patients were included in the analysis with a mean age of 42.0 ± 12.6 years (range, 16-75) and mean BMI of 24.9 ± 4.8 (range, 17.2-38.9). Most patients had symptoms of duration ≥1 year (60.2%). Six patients (5.8%) had arthroscopic revisions, and 2 patients (1.9%) converted to total hip arthroplasty by 5-year follow-up. Patients with BMI ≥30.0 had significantly lower postoperative mHHS (P = .03) and NAHS (P = .04) than those with BMI <25.0. Higher BMI was associated with reduced improvement in mHHS (ß = -1.14, P = .02) and NAHS (ß = -1.34, P < .001) and lower odds of achieving the mHHS MCID (odds ratio [OR] = 0.82, P = .02) and NAHS MCID (OR = 0.88, P = .04). Older age was predictive of reduced improvement in NAHS (ß = -0.31, P = .046). Symptom duration ≥1 year was predictive of higher odds of achieving the NAHS MCID (OR = 3.98, P = .02). CONCLUSIONS: Female patients across a wide range of ages, BMIs, and symptom durations experience satisfactory 5-year outcomes following primary hip arthroscopy, but higher BMI is associated with reduced improvement in patient-reported outcomes. LEVEL OF EVIDENCE: Level III, retrospective comparative prognostic trial.

BACKGROUND: Several risk factors have been identified for the development of postoperative shoulder stiffness, and there has been increasing interest in orthopedic literature regarding patient-reported allergy (PRA) as an identifiable risk factor for adverse outcomes. The purpose of this study is to determine whether PRAs are associated with subsequent rates of diagnosis of adhesive capsulitis (AC) or return to the operating room for postoperative shoulder stiffness within 2 years after arthroscopic rotator cuff repair (ARCR). METHODS: Current Procedural Terminology surgical billing codes were used to retrospectively identify patients who underwent ARCR at a single urban academic institution from January 2012 to December 2020 with minimum 2-year follow-up. Lysis of adhesions (LOA), manipulation under anesthesia (MUA), and AC of the shoulder were further queried within 2 years postoperatively for the ipsilateral shoulder. Patients were excluded if they had undergone ipsilateral MUA/LOA or received a diagnosis of AC before the index procedure. Demographic characteristics and medical comorbidities (hypertension, diabetes, hyperlipidemia, and hypothyroidism) were extracted from electronic medical records. Baseline characteristics were compared between patients with and without PRAs. Multivariate logistic regression analyses were performed to determine the association of the presence of PRAs overall, as well as the presence of 1, 2, or 3 or more PRAs, with subsequent MUA/LOA or diagnosis of AC within 2 years postoperatively. RESULTS: Of 7057 patients identified in the study period, 6583 were eligible for the final analysis. The mean age was 56.6 ± 11.7 years, and the mean body mass index was 29.1 ± 5.6. Overall, 19.3% of patients (n = 1271) reported at least 1 allergy, and 7.1% (n = 469) had >1 PRA. A total of 44 patients (0.7%) underwent subsequent ipsilateral MUA/LOA within 2 years postoperatively, whereas 93 patients (1.4%) received a diagnosis of ipsilateral AC in the same time frame. PRAs were significantly associated with subsequent diagnosis of AC (odds ratio [OR]: 2.39; 95% confidence interval [CI]: 1.45-3.92; P < .001), but not MUA/LOA (OR: 1.97, 95% CI: 1.26-3.61; P = .133). Patients with 2 PRAs had greater odds of being diagnosed with AC than patients with 1 PRA (OR: 2.74; 95% CI: 1.14-5.99; P = .012). Although this association was nonsignificant for MUA/LOA, patients with 2 PRAs (OR: 2.67; 95% CI: 0.96-8.80; P = .059) demonstrated a similar statistical trend. CONCLUSION: PRAs are associated with increased odds of receiving a diagnosis of AC within 2 years after ARCR but were not found to be associated with return to the operating room for postoperative stiffness.

The lateral patellofemoral joint, composed of multiple soft-tissue structures, balances the knee by aiding patella tracking, stability, and force distribution. Arthroscopic lateral release is a well-described procedure that addresses patellofemoral knee pain and, in cases with patellar instability, may be combined with medial stabilization. In-office needle arthroscopy is an up-trending technique that simultaneously diagnoses and treats patellofemoral pathology in the office, leading to a quicker patient recovery, reduced cost, and improved patient satisfaction. The purpose of this Technical Note is to describe in-office needle arthroscopy technique to address patellofemoral pain and lateral patellar mal-tracking, with special consideration for achieving adequate local anesthesia, proper indications, adequate visualization, and the advantages of performing these procedures in the office rather than the operating room.

The purpose of this technical note is to describe the technique for performing in-office needle arthroscopy for chondral or osteochondral contained lesions of the knee, with special consideration of the technique for obtaining adequate local anesthesia, proper indications, adequate visualization, and the advantages of performing these procedures in the office rather than the operating room.
RESUMEN
There are several eponyms used in the assessment and management of calcaneus fractures. However, the origin of these eponyms is no longer widely known. Named for orthopaedic surgeons who made substantial contributions to the management of calcaneus fractures as well as the field of orthopaedic surgery, understanding the context of how these descriptors were derived helps give context to their use in the present day. The purpose of this review is to provide a historical perspective and comprehensive collection of the most common eponyms related to calcaneus fractures.

Background: The exact pathogenesis of idiopathic adhesive capsulitis (IAC) is not fully understood, but an inflammatory profibrotic cascade, largely mediated by transforming growth factor-beta 1 (TGF- ß1) has been implicated. Angiotensin II receptor blockers (ARBs) and angiotensin-converting enzyme inhibitors (ACE-Is) both decrease the activity of TGF-ß1. The aim of this study was to determine the impact of ACE-Is or ARBs use on the need for operative intervention in IAC. Methods: This was a retrospective cohort study of patients from a single institutional database with IAC, divided into two cohorts, with and without ACE-I and/or ARB use as the primary exposure and a minimum 2-year follow-up. The primary outcome measured was the incidence of operative intervention including manipulation under anesthesia (MUA) and arthroscopic capsular release (ACR). Additional multivariable logistic regression analysis was performed to evaluate associations between ACE-I/ARB use and likelihood of undergoing an operative procedure. Results: A total of 17,645 patients met inclusion criteria, with 5424 patients in the ACE-I/ARB cohort and 12,221 in the non-ACE-I/ARB cohort. Overall, 422 (2.4%) patients underwent surgical treatment, 378 (2.1%) ACR, and 74 (0.4%) MUA. There was no significant difference between cohorts in the frequency of surgical procedures or time to procedure since diagnosis. There were no significant differences between individual ACE-Is or ARBs, although Losartan was found to have a trend of decreased rate of intervention (31.7% vs. 36.8%, P = .209) when compared to patients not on losartan that did not reach statistical significance. Patient factors predictive of undergoing MUA/ACR were diabetes (P = .013), obesity (P < .001), and male sex (P < .001). Increasing patient age reduces the likelihood of undergoing operative intervention, with patients aged 50-70 years (P = .022) and age >70 years (P < .001) demonstrating reduced odds as compared to patients aged <30 years. Conclusion: Patients with IAC have an overall low (2.4%) rate of requiring surgical intervention. While the antifibrotic mechanism of ACE inhibitors and ARBs did not significantly affect the rate of requiring surgical intervention, male gender, obesity, younger age, and diabetes, all increased the risk for operative intervention. Losartan, specifically, may have a disease modifying effect on IAC that should be investigated with larger controlled trials.
RESUMEN
Subacromial decompression with acromioplasty is among the most commonly performed shoulder procedures. The advantages of in-office nano-arthroscopy include the capability of diagnosing and treating subacromial impingement, swifter patient recovery, improved cost-effectiveness, and superior patient satisfaction. The purpose of this technical report is to describe our technique for performing in-office nano-arthroscopy for subacromial decompression (subacromial bursectomy and acromioplasty), with a particular focus on appropriate indications, providing sufficient local anesthesia, optimizing visualization, and discussing the advantages of the in-office setting compared to the operating room.
RESUMEN
PURPOSE: To identify differences in the time taken to achieve the minimum clinically important difference (MCID), substantial clinical benefit (SCB), and patient-acceptable symptom state (PASS) following primary hip arthroscopy for the treatment of femoroacetabular impingement syndrome (FAIS) among patients of different body mass index (BMI) categories. METHODS: We conducted a retrospective comparative study of hip arthroscopy patients with minimum 2-year follow-up. BMI categories were defined as normal (18.5 ≤ BMI < 25.0), overweight (25.0 ≤ BMI <30.0), or class I obese (30.0≤BMI<35.0). All subjects completed the modified Harris Hip Score (mHHS) prior to surgery and at 6 months, 1 year, and 2 years postoperative. MCID and SCB cutoffs were defined as pre-to-postoperative increases in mHHS by ≥8.2 and ≥19.8, respectively. PASS cutoff was set at postoperative mHHS ≥74. Time to achievement of each milestone was compared using the interval-censored EMICM algorithm. The effect of BMI was adjusted for age and sex using an interval-censored proportional hazards model. RESULTS: 285 patients were included in the analysis: 150 (52.6%) normal BMI, 99 (34.7%) overweight, and 36 (12.6%) obese. Obese patients had lower mHHS at baseline (P = .006) and at 2-year follow-up (P = .008). There were no significant intergroup differences in time to achievement for MCID (P = .92) or SCB (P = .69), but obese patients had longer time to PASS than normal BMI patients (P = .047). Multivariable analysis found obesity to be predictive of longer time to PASS (HR = .55; P = .007) but not MCID (HR = 0.91; P = .68) or SCB (HR = 1.06; P = .30). CONCLUSIONS: Class I obesity is associated with delays in achieving a literature-defined PASS threshold after primary hip arthroscopy for FAIS. LEVEL OF EVIDENCE: Level III, retrospective comparative study.
