Improved Squat and Gait Biomechanics 6-Months Post-Arthroscopic Surgery for Femoroacetabular Impingement:

Objectives:This study aimed to assess gait and squat biomechanics 6-months following arthroscopic surgery for femoroacetabular impingement.Methods:Symptomatic patients with clinical and radiographic diagnosis of FAI who had failed non-operative treatment underwent gait and squat analysis preoperatively and at 6-months postoperatively following arthroscopic surgery for FAI. Age- and BMI-matched controls without radiographic FAI or other lumbar or lower extremity pathology underwent a single analysis for comparison. Comparisons between preoperative and 6-month postoperative gait and squat parameters as well as comparison to the control group were performed using paired and independent sample t-tests. Statistical significance was set at p 0.05), respectively; while BMI was 23.5±5.1 kg/m2 vs. 22.8±3.5 kg/m2 (p>0.05). All gait parameters were unchanged between preoperative and 6-mo...
