Purpose To evaluate return‐to‐sport (RTS) rates and patient‐reported outcome measures (PROMs) following hip arthroscopic labral repair for femoroacetabular impingement in active basketball players with a minimum of 2‐year follow‐up. Methods All patients who were active basketball players and underwent hip arthroscopy with labral repair for femoroacetabular impingement from 2009 to 2022 were identified. Patients were evaluated for postoperative RTS and revision surgery at a minimum 2‐year follow‐up. RTS was defined as resuming basketball participation, at any level. Modified Harris Hip Score (mHHS), Hip Outcome Score‐Activities of Daily Living (HOS‐ADL) and Sport (HOS‐Sport), and surgery satisfaction were also collected. Results Sixty‐seven hips in 54 athletes (29 male, 25 female) with a mean age of 22.2 years (range 13‐39 years) were included. Eighty‐six (86%) were recreational or high school basketball players. There was significant improvement in all PROMs from baseline to a minimum 2‐year follow‐up (all P < .001). After excluding for athletes who did not RTS for nonmedical reasons, 78% of athletes returned to basketball following hip arthroscopy. Including patients who cited nonmedical reasons for not returning, the overall RTS rate was 65%. Athletes who RTS had significantly higher mHHS ( P = .012), HOS‐ADL ( P = .006), and HOS‐Sport ( P = .002), as well as lower visual analog scale pain (2.2 vs 3.4, P = .037) than those who did not RTS. Calculated minimal clinically important difference values were 8.3 for mHHS, 7.2 for HOS‐ADL, and 13.4 for HOS‐Sport. Anchor‐based patient acceptable symptom state calculations yielded thresholds of 83.5 for mHHS, 92.6 for HOS‐ADL, and 79.2 for HOS‐Sport—with 70%, 63%, and 67% of patients achieving these thresholds, respectively. Conclusions Basketball players who undergo hip arthroscopic labral repair for femoroacetabular impingement show significant improvements in PROMs with 78% RTS rate at a minimum 2‐year follow‐up. Although many athletes discontinued basketball for reasons unrelated to the hip, 18% cited hip issues. Basketball players who successfully return to basketball report higher PROMs than nonreturners, and cohort‐specific minimal clinically important difference analysis indicates that most athletes achieve clinically meaningful improvements.

Purpose To investigate outcomes among patients undergoing total hip arthroplasty after hip arthroscopy (HA‐THA) compared with a matched cohort undergoing primary THA without prior arthroscopy (Only‐THA). Methods Patients who underwent THA after primary hip arthroscopic labral repair from 2009 to 2022 at a single institution were identified. Cases were propensity‐matched 1:4 to primary THA controls by age at THA, sex, body mass index (BMI), surgical approach, and year of surgery. At minimum 2‐year follow‐up, patient‐reported outcomes (PROs)—Forgotten Joint Score (FJS), modified Harris Hip Score (mHHS), and Hip Disability and Osteoarthritis Outcome Score Pain (HOOS‐Pain)—were analyzed. Results Sixty‐two hips (age: 47.5 ± 9.3 years, BMI: 29.7 ± 6.2 kg/m 2 ) were matched to 248 Only‐THA hips (age: 47.9 ± 10 years, BMI: 29.5 ± 5.8 kg/m 2 ). Although both HA‐THA and Only‐THA patients showed significant ( P < .001) postoperative improvements in PROs, HA‐THA patients reported significantly lower postoperative FJS, mHHS, HOOS‐Pain, and inferior Visual Analog Scale pain scores ( P < .001) compared with Only‐THA controls. A cohort‐specific minimal clinical important difference for mHHS was calculated as 9.6 points, with 75.7% of HA‐THA and 87.5% Only‐THA patients achieving this threshold ( P = . 077). At mean 6.6 ± 3.3 years follow‐up, HA‐THA patients with preoperative Tönnis grades 1 reported significantly decreased FJS, mHHS, and HOOS‐Pain compared with HA‐THA patients with preoperative Tönnis grade 2‐3 ( P ≤ .05). HA‐THA patients with Tönnis grade 1 also exhibited worse PROs ( P < .001) compared with Only‐THA controls. Although there were no differences in complication rates between HA‐THA and Only‐THA patients (8% vs. 5%, P = .49), all‐cause reoperation was greater amongst HA‐THA (10% vs. 2%, P = .01). Conclusions Patients undergoing THA after prior hip arthroscopy showed modestly inferior subjective outcomes at mid‐term follow up compared with an age‐matched cohort without prior arthroscopy. Although both groups showed meaningful improvement, a smaller proportion of HA‐THA patients achieved the cohort‐specific MCID for mHHS compared with Only‐THA controls.

Background: Acetabular overcoverage (pincer morphology) has been suggested to be both a source of pain and dysfunction and potentially protective against osteoarthritic change. Purpose: To compare the minimum 5-year clinical outcomes of patients undergoing primary hip arthroscopic labral repair with a lateral center edge angle (LCEA) of ≥40° as compared with nondysplastic controls with an LCEA of 25° to 40°. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective review was performed to identify all patients who underwent primary hip arthroscopic labral repair between 2009 and 2019 at a single academic institution. Patients with an LCEA of ≥40° (pincer) were propensity-matched to nondysplastic controls with an LCEA of 25° to 40° on a 1-to-2 basis by sex, age, body mass index, and surgery year. Patient-reported outcome measures (PROMs)—including visual analog scale, Tegner activity score, modified Harris Hip Score, International Hip Outcome Tool (iHOT-12), and Hip Outcome Score were analyzed—as were reoperations and conversions to total hip arthroplasty (THA). Results: A total of 55 patients with pincer morphology (preoperative LCEA: 41.9°± 2.1°) were matched to 110 nondysplastic controls (LCEA: 31.2°± 4.1°), resulting in a total of 165 hips in 163 patients (67% women, mean age: 37.7 ± 9 years). Pincer patients were corrected to a mean postoperative LCEA of 38.7°± 4.1º ( P < .001), with 22 pincer patients having residual overcoverage; namely, a postoperative LCEA ≥40° (range, 40°-45.8°). There were no differences between cohorts regarding intraoperative characteristics—including femoral and acetabular Outerbridge grade—as well as capsulotomy type and the presence of capsular repair ( P ≥ .210). At a mean 8-year follow-up (range, 5.1-13.2), there was no difference in any postoperative PROMs between pincers and controls ( P ≥ .215) and no difference in PROMs between patients with residual overcoverage and pincer patients with a postoperatively normalized LCEA ( P ≥ .291). At final follow-up, 4 patients in the pincer cohort (7%) and 21 controls (19%) converted to THA ( P = .046). Conclusion: Patients with lateral acetabular overcoverage demonstrated similar and satisfactory postoperative PROMs at a minimum 5-year follow-up compared with propensity-matched nondysplastic controls, regardless of whether the LCEA was corrected to <40°. Of note, nondysplastic controls demonstrated a higher rate of conversion to THA, suggesting a potentially chondroprotective role for acetabular overcoverage.

Abstract The lateral and medial meniscus play vital roles in load distribution across the knee joint and in the prevention of knee osteoarthritis. As such, every effort should be made to save and repair the meniscus when possible, as partial and total meniscectomies have been shown to impair the meniscus’ ability to effectively dissipate shock. Recently, an algorithm—coined the “ABCs of meniscal repair”—has emerged as a blueprint for optimizing the success of a meniscal repair. The “ABCs of meniscal repair” refer to anatomic reduction, biologic augmentation, and circumferential compression across the meniscus tear, respectively. In this technique, we describe a modified use of the arthroscopic skid that allows for access to difficult‐to‐reach peripheral meniscal tears while simultaneously aiding in the anatomic reduction of the tear.

Abstract Femoroacetabular impingement with cam morphology that fails nonoperative management can be addressed with hip arthroscopy and cam resection. There exists a wide variation of cam morphology due to various etiologies that can make some cam lesions more challenging to address. A thorough preoperative evaluation and the utilization of a variety of intraoperative techniques can allow for adequate arthroscopic resection of these otherwise challenging cam lesions. In this technique video, we describe a systematic approach for the preoperative assessment of femoroacetabular impingement due to a cam lesion and consideration of different approaches for arthroscopic resection based on cam‐specific morphology.

Background: Total knee arthroplasty (TKA) is the treatment of choice for end-stage knee osteoarthritis in many patients. In younger patients with predominantly medial compartment disease, high tibial osteotomy (HTO) is performed as a joint-preserving treatment. However, concerns remain regarding potentially compromised outcomes of TKA after previous HTO given the axial deviation, osteotomy site, secondary surgery, previous hardware, and instrumentation. Therefore, this study compared long-term implant survival, revision, and infection rates, and patient-reported outcomes between patients undergoing TKA after HTO and matched TKA-only controls. Methods: Postoperative complications and revision surgeries were prospectively recorded in patients who underwent TKA from 2000 to 2023 at a single academic center. Patients with previous ipsilateral HTO formed the study group and were propensity matched 1:2 to TKA-only patients without a previous osteotomy based on age, sex, and body mass index. Knee Society Scores (KSS) were collected prospectively. Implant survivorship was analyzed using Kaplan-Meier survival curves and Cox proportional hazards models. Results: The study included 134 HTO-TKA and 268 matched TKA-only patients, with a mean follow-up of 10.5 ± 6.4 years (range: 0-24 years) after TKA. Both groups showed significant postoperative improvements in KSS (p < 0.02) with comparable clinical outcomes (HTO-TKA: 79.0 (6.0), TKA-only: 79.0 (11.8)). Revision arthroplasty rates were 5.2% for HTO-TKA and 4.5% for TKA-only (p = 0.69); the mean time to revision was 8.1 ± 8.7 years vs. 4.4 ± 3.5 years, respectively (p = 0.30). Infection rates were 2.2% and 1.1%, respectively (p = 0.74). Conclusions: Revision and infection rates were comparable between HTO-TKA and matched TKA-only patients, with no statistically significant differences. Our findings demonstrate comparable patient-reported outcomes in both groups. These findings indicate that a previous HTO does not adversely affect TKA implant longevity or clinical outcomes when compared with matched primary TKA patients within the US population.

Abstract A posterior tibial slope (PTS) greater than 12° is an established risk factor for anterior cruciate ligament graft reconstruction failure. Reducing PTS is thus considered protective to the anterior cruciate ligament graft, and it can be achieved through an anterior closing‐wedge osteotomy. Prior to the procedure, PTS should be accurately measured to determine the amount of correction that is needed. Radiographic films remain the gold standard for measuring PTS. The purpose of this presentation is to show validated and reproducible step‐by‐step techniques for measuring PTS and anterior tibial translation for anterior closing‐wedge osteotomy using monopedal full‐length weight‐bearing tibia standing radiographs.

Abstract Tunnel convergence in multiligament knee surgery remains a technical challenge. Anterior cruciate ligament (ACL) femoral sockets/tunnels and lateral collateral ligament (LCL) femoral sockets/tunnels during anatomic posterolateral corner (PLC) reconstructions are particularly vulnerable to convergence. This is secondary to the limited amount of bony real estate available on the lateral distal femur. Previous studies have attempted to define a specific angle to direct the LCL tunnel away from the ACL tunnel. However, inconsistency with ACL femoral socket creation and variability in bony architecture can make this strategy unreliable. This surgical technique describes how to minimize the risk of ACL and LCL tunnel convergence during ACL and PLC reconstructions.

Hip arthroscopy is an increasingly common procedure to treat intra‐articular conditions such as labral tears and femoroacetabular impingement. With the increase in frequency of such procedures, so too are revision arthroscopic hip procedures. Capsular repair in the setting of revision hip arthroscopy can be challenging due to the presence of adhesions and scar tissue formation that obscure tissue planes, suboptimal quality of residual capsular tissue, and the presence of capsular tissue defects. This technical note aims to describe the key surgical principles and considerations of revision hip capsular closure.

Introduction In recent years collared femoral stems have been increasingly utilized in total hip arthroplasty (THA) for their ability to improve rotational stability, metaphyseal load transfer, and prevent periprosthetic femoral fracture (PFF). While literature has demonstrated their benefit over collarless stems, the clinical and biomechanical implications of a postoperative collar–calcar gap (CCG) after implantation remain incompletely understood. Objective The purpose of this scoping review was to evaluate existing literature around CCG in primary THA. Methods A PRISMA Scoping Review literature search was conducted across Ovid MEDLINE, Embase, Cochrane CENTRAL, and Scopus databases. Studies were included if they reported CCG incidence, subsidence, remodeling, or biomechanical performance in primary THA. Two independent reviewers screened studies and extracted data, and clinical study quality was assessed using the Newcastle–Ottawa Scale. Results A total of 408 studies were identified and 11 met inclusion criteria. The incidence of postoperative CCG varied from 18.7% to 53.9%. Most gaps demonstrated closure over time (66–76%). Biomechanical and finite element studies showed improved stability, reduced micromotion, and decreased periprosthetic fracture risk when direct collar–calcar contact was achieved. In contrast, stems with persistent gaps demonstrated increased subsidence (up to 19% vs 1.3%) and biomechanical behavior comparable to collarless designs. Conclusion CCG is common following THA. The majority of gaps resolve, however biomechanical evidence demonstrates that the advantages of collared stems depend on calcar contact. Preventing CCG may optimize early implant stability, though surgical technique must balance mechanical engagement with preservation of proximal femoral bone stock.
