A Superolateral Cam Lesion Location Increases Odds of Total Hip Arthroplasty 5 Years After Hip Arthroscopy

Editorial Commentary: Younger Patients With Hip Femoroacetabular Impingement Syndrome and a Superolateral Cam Lesion Location May Require Aggressive Treatment to Prevent Post-Arthroscopy Total Hip Replacement

Hip femoroacetabular impingement syndrome is observed in 47% to 74% of patients with hip pain. Femoroacetabular impingement syndrome may result in osteoarthritis. It is well known that cam lesion volume and hip alpha angle are critical parameters determining patient outcomes. Recent research shows that a superolateral cam lesion location increases risk of hip arthroplasty at 5 years, and that this is more common in younger patients. The clinical relevance is that we may need to more aggressively treat superolateral cam lesions in younger patients, pending additional research to determine whether location is destiny.
