AI Article Synopsis
- The study examined the safety and outcomes of hip arthroscopy using traction in patients who had previously undergone lower-extremity arthroplasty.
- Both groups (prior arthroplasty and no prior surgery) showed significant improvement in hip function scores (MHHS and NAHS) after the procedure, with no significant differences between them.
- Overall, hip arthroscopy with traction is considered safe for patients with previous joint replacements and leads to positive short-term results.
Article Abstract
Purpose: Given the potential for injury due to joint-distraction techniques during hip arthroscopy, this study investigated the outcomes and safety of traction during hip arthroscopy in a series of patients with a prior lower-extremity arthroplasty.
Methods: Nine patients with a prior hip or knee arthroplasty (Group 1) and a matched cohort of nine additional patients with no prior hip surgery (Group 2) who underwent hip arthroscopy with traction between 2011 and 2013 were evaluated. Collected data included traction and operative times, Modified Harris Hip Scores (MHHS), Non-Arthritic Hip Scores (NAHS), and postoperative complications.
Results: Both operative (p = 1) and traction (p = 0.11) times were similar in each group. Each group had a significant improvement in MHHS from baseline to final follow-up: from 39 to 73 (p < 0.001) in Group 1 and from 49 to 75 (p = 0.03) in Group 2. Similarly, the NAHS showed significant improvement in each group from baseline to final follow-up: from 41 to 71 (p < 0.001) in Group 1 and from 48 to 74 (p = 0.02) in Group 2. There was no difference between groups in MHHS or NAHS. There was one postoperative complication in Group 1 (a recurrent labral tear) and no complications from an existing arthroplasty or in Group 2.
Conclusions: Hip arthroscopy in patients with a lower-extremity arthroplasty yields improved short-term clinical outcomes without increased complications. The use of traction during hip arthroscopy is safe in this population.

Purpose: Studies evaluating the long-term survival rate, patient satisfaction, and conversion to total hip arthroplasty (THA) are limited. The aim of this study was to evaluate satisfaction and hip survival at a minimum 10-year follow-up in patients following hip arthroscopy for femoroacetabular impingement syndrome (FAIS).
Methods: A total of 164 patients underwent hip arthroscopy for FAIS between 2007 and 2012; of these, 76 (49 men and 27 women; mean age, 40.

Purpose: To assess whether capsular closure during hip arthroscopy with periportal capsulotomy affects 2-year postoperative outcomes for patients with femoroacetabular impingement syndrome (FAIS) without hypermobility.
Methods: A matched-cohort retrospective analysis of a single institutional database of patients who underwent hip arthroscopy with periportal capsulotomy for management of FAIS between 2014 and 2022 was performed. Study inclusion criteria consisted of patients with FAIS who exhibited no signs of generalized ligamentous laxity (GLL) (Beighton score 0).

The evolution of orthopaedics has witnessed a pronounced shift from generalist practice to subspecialisation, a trend that has fundamentally reshaped the field over the past century. Originally, orthopaedic surgeons were trained to address a broad spectrum of musculoskeletal conditions. However, increasing complexity and specialization in knowledge have driven a progressive narrowing of focus within orthopaedics.
