Editorial Commentary: Hip Arthroscopy in Patients With Elevated Body Mass Index Shows Outcome Improvement but Inferior Outcomes to Nonobese Patients.

Abstract

Hip arthroscopy for femoroacetabular impingement syndrome has been shown to achieve favorable long-term outcomes, but patients with elevated body mass index (BMI) show improved but inferior outcomes and a significantly higher rate of conversion to total hip arthroplasty in comparison to nonobese controls. BMI is a well-known risk factor for the development of osteoarthritis in various joints, including the hip, owing to various factors, including increased mechanical loading and systemic inflammation. It is important to recognize that BMI is a modifiable variable that can change over time, and on its own, BMI does not differentiate between lean muscle mass and adipose tissue.
