Summary:
This study compares gait and functional outcomes in adolescent and young adult patients with femoroacetabular impingement (FAI) treated with either open surgical hip dislocation (SHD) or arthroscopic surgery.
Methods:
Inclusion Criteria: Adolescent/young adult patients (≤20 years old) with FAI undergoing SHD or arthroscopic surgery. Exclusion Criteria: Not specified. Intervention: Comparison of gait and functional outcomes after SHD versus arthroscopic surgery for FAI. Outcomes Measured: Gait assessment: Barefoot walking with analysis of hip flexion, trunk, pelvis, and hip kinematics. Balance assessment: 30-second single-limb balance trial on the affected side. Clinical outcomes: Harris Hip Score preoperatively and postoperatively (minimum 8 months). Data Analysis: Paired-samples t-test for within-group comparisons. Independent samples t-test for between-group comparisons (α=0.05).

Not specified
Results:
Pre- to Postoperative Improvements in Harris Hip Score: SHD group: From 64.8 ± 16.4 to 81.8 ± 17.8 (P < 0.001). Arthroscopy group: From 57.0 ± 16.7 to 84.7 ± 19.7 (P < 0.001). Gait Analysis: Significant increase in maximum hip flexion for SHD group (32.3 ± 5.7 to 36.1 ± 5.2, P = 0.003). No significant changes in trunk, pelvis, or hip kinematics in either group. Balance Task: The arthroscopy group showed a significantly longer balance duration (18.8 ± 7.8 seconds) compared to the SHD group (14.2 ± 2.7 seconds, P = 0.008). No significant differences in trunk or pelvis position during balance.
Conclusions:
Both SHD and arthroscopic surgery for FAI resulted in significant clinical improvements with no clinically significant abductor dysfunction after 1 year. The arthroscopy group demonstrated superior balance performance compared to the SHD group postoperatively. Further studies are needed to investigate more dynamic tasks to assess potential differences between treatment groups.
