Lay Abstract

INTRODUCTION: The purpose of this study was to present minimum two-year outcomes for patients undergoing arthroscopic treatment for acetabular labral tears and concomitant femoroacetabular impingement using a novel puncture capsulotomy technique, which preserves capsuloligamentous integrity by avoiding transection of the iliofemoral ligament.

 

METHODS: This is a case series on patients who underwent arthroscopic acetabular labral tear treatment between December 2013 and May 2019. Outcome data consisted of patient-reported outcome measures.

 

RESULTS: 163 hips were included in this study with a mean patient follow-up of 30.4 (95% CI: 28.5-32.3) months. There were significant improvements in mean enrollment compared to final follow-up scores for the iHOT-33 [39.6 (36.8-42.4) vs. 76.1 (72.7-79.6)], HOS-ADL [69.9 (66.9-72.9) vs 89.3 (87.3-91.3)], mHHS [60.1 (57.8-62.3) vs. 84.9 (82.5-87.2)] and HOS-Sport [41.5 (37.7-45.4) vs. 75.7 (71.7-79.7)], (p<0.001 for all). VAS pain scores were noted to significantly improve throughout the duration of the postoperative period. At 2-year follow-up, 81.0%, 62.0%, 58.9% of hips achieved clinically meaningful iHOT-33 thresholds for MCID, PASS and SCB, respectively.

 

CONCLUSION: The puncture capsulotomy approach for hip arthroscopy demonstrated significantly improved functional and clinical outcomes at a minimum of two-years follow-up. Thus, demonstrating that puncture capsulotomy is an efficacious technique for arthroscopic acetabular labral repair.

Clinical Implications
Puncture capsulotomy addresses the clinical demand for an alternative arthroscopic surgical approach that preserves capsuloligamentous integrity, maintains adequate osseous visualization and demonstrates excellent functional outcomes
