Patients Undergoing Hip Arthroscopy With Periportal and Puncture Capsulotomy Demonstrate Favorable Outcomes at...

To evaluate whether patients undergoing primary hip arthroscopy with periportal or puncture capsulotomy demonstrate improved patient-reported outcomes (PROs) at minimum 2-year follow-up when compared with preoperative PROs.

A systematic review was performed and registered in PROSPERO under ID: CRD42023466053. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), and Scopus were searched in October of 2024 using the following string: (capsul∗ OR puncture OR periportal) and (hip OR femoroacetabular impingement) AND (arthroscop∗). Articles were included if they reported preoperative and minimum 2-year follow-up PROs in patients who underwent hip arthroscopy for the treatment of femoroacetabular impingement and/or labral tears with periportal or puncture capsulotomy and were written in English.

Six studies were included, with 5 studies reporting outcomes on periportal capsulotomy (313 hips) and 1 study on puncture capsulotomy (163 hips). Three studies were Level IV evidence and 3 were Level III. Study periods ranged from 2013 to 2020. Average improvement in the modified Harris Hip Score ranged from 21.1 to 32.56 (I² = 97%). Average improvement in the visual analog scale for pain ranged from -2.5 to -5.3 (I² = 94%). Minimal clinically important difference was achieved by 65.0% to 100% of patients for Hip Outcome Score - Activities of Daily Living, 71.8% to 88% for Hip Outcome Score-Sport, and 62.5% to 78% for analog scale for pain. Three studies reported rates of secondary total hip arthroplasty, ranging from 0% to 1.7%.

Patients undergoing hip arthroscopy with periportal capsulotomy showed improvements in multiple PROs at a minimum of 2-year follow-up. Periportal capsulotomy appears to be an effective capsulotomy technique in patients undergoing hip arthroscopy for the treatment of femoroacetabular impingement and/or labral tears. Preliminary evidence shows puncture capsulotomy may be an effective way to access the capsule during hip arthroscopy, but conclusions are limited, given the lack of studies available.
