Clinical Outcomes and Return to Sport in Competitive Athletes Undergoing Arthroscopic Iliopsoas Fractional Lengthening Compared With a Matched Control Group Without Iliopsoas Fractional Lengthening.
Abstract: To compare the minimum 2-year outcomes and return to sports in competitive athletes after arthroscopic iliopsoas fractional lengthening (IFL) and treatment for femoroacetabular impingement (FAI) to competitive athletes treated for FAI who did not undergo IFL.
Methods: Data were prospectively collected and retrospectively reviewed between November 2009 and April 2014. Included patients were high school, collegiate, or professional athletes who underwent arthroscopic IFL, treatment for FAI, and preoperative modified Harris Hip Score, Non-Arthritic Athletic Hip Score, Hip Outcome Score-Sports Specific Subscale, and visual analog scale. Exclusion criteria were patients younger than 16 years, Tönnis grade >1, microfracture, abductor pathology, and previous hip conditions. A subgroup of athletes were matched to athletes who did not undergo IFL by age ± 5 years, sex, and body mass index ± 5.
