Pediatric and adolescent patients treated for femoroacetabular impingement with hip arthroscopy showed good results at 5-year follow-up, according to researchers from the Steadman Philippon Research Institute.
In 60 patients between 11 years and 16 years of age, modified Harris Hip Scores increased from mean 57 to mean 91 at mean 3-year follow-up, according to the abstract. While clinical scores showed improvement, 13% of patients needed a second procedure for treatment of capsulolabral adhesions. Researchers also reported a significant association between age and alpha angle.
“Hip arthroscopy in the pediatric and adolescent population is a safe procedure, with excellent clinical outcomes at 2 to 5 years,” Marc J. Philippon, MD, wrote in the abstract.
Cam and pincer impingement was found in 10% and 15% of patients, respectively, while 75% of patients had a mixed impingement type. The femoral physis was closed in 71%, open in 10% and partially closed in 19% of patients, according to the abstract. Patients were excluded from the study if they had previous hip surgery or if they had a center-edge angle below 25°.
