Objective:

To investigate whether gait speed improves after hip arthroscopy with iliofemoral ligament (IFL) preservation and whether pelvic jerk at 1 month postoperatively is associated with gait speed at 6 months postoperatively.

Approach:

• Participants: 35 patients diagnosed with femoroacetabular impingement (FAI) underwent primary hip arthroscopy. Assessments were conducted preoperatively and at 1 and 6 months postoperatively.
• Surgical Technique: A senior surgeon performed arthroscopic hip femoroplasty and labral repair using a skip capsulotomy technique to preserve the IFL.
• Postoperative Rehabilitation: Patients had no restrictions on weight-bearing or hip range of motion, with ambulation starting 3 hours post-surgery.
• Outcome Measures: Patient-reported outcome measures (PROMs) and physical functional assessments were collected, along with gait analysis using inertial sensors.

Key Findings:

• Gait speed is a key functional indicator of recovery after hip arthroscopy.
• Pelvic jerk during early stance may correlate with gait speed recovery at 6 months.

Interpretation:

Limitations:

• Single-center study may limit generalizability.
• Small sample size may affect the robustness of findings.

Conclusion:
