Purpose To prospectively investigate subjective anterior groin pain, patient‐reported outcome measures, complications, reoperation rates, and hip flexion strength after arthroscopic iliopsoas fractional lengthening. Methods From 2023 to 2025, patients with persistent groin pain after total hip arthroplasty refractory to conservative management undergoing arthroscopic iliopsoas fractional lengthening were prospectively identified at 2 tertiary referral centers. Pre‐ and postoperative outcomes at a minimum 6‐month follow‐up including the Visual Analog Scale, Tegner activity scale, Single Assessment Numeric Evaluation, and subjective anterior groin pain and hip flexion strength were analyzed. Results Fifty‐nine hips in 56 patients were included (age: 64.9 ± 9.8 years, 59% women, body mass index: 30.0 ± 5.8 kg/m 2 ) and followed for 10.0 ± 6.9 months postoperatively (range: 4‐25 months). Patients experienced significant ( P < .001) postoperative improvements in the Visual Analog Scale at rest (1.4 ± 2.2 vs 2.8 ± 2.1), Visual Analog Scale with use (3.0 ± 2.9 vs 7.8 ± 1.8), Tegner activity scale (2.8 ± 1.2 vs 2.0 ± 1.0), and Single Assessment Numeric Evaluation score (73.8 ± 22.5 vs 47.7 ± 22.2). Postoperative surgical satisfaction was 8.0 ± 2.7 (scale: 0‐10). Nearly 90% of patients reported feeling much or slightly better regarding their anterior groin pain postoperatively at 2‐week (91%), 6‐week (88%), 3‐month (91%), and final follow‐up (92%). Regarding hip flexion strength, ≥66% reported feeling much or slightly better at 2‐week (73%), 6‐week (95%), 3‐month (89%), and final follow‐up (66%). Three hips (6%) underwent reoperation at the final follow‐up (1 acetabular screw removal with open revision release, 1 revision total hip arthroplasty for loosening, and 1 two‐stage exchange for nonacute periprosthetic joint infection). Conclusions Nearly 90% of patients who underwent arthroscopic iliopsoas fractional lengthening after primary total hip arthroplasty reported improved anterior groin pain, whereas two‐thirds reported increased subjective hip flexion strength throughout the follow‐up. Of note, clinically meaningful improvement in pain at rest was achieved by 50% of patients based on cohort‐specific minimal clinically important difference criteria. Level of Evidence Level IV, retrospective therapeutic case series.

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.
