Overview
Brief Summary
The purpose of this study is to review the impact of obesity on subsidence and clinical outcome after short stem total hip arthroplasty.
Detailed Description
Short stem total hip arthroplasty (THA) has gained popularity due to its bone-sparing technique, but its outcomes in obese patients remain uncertain. While studies on the mid-term outcome in a general patient cohort provide excellent results in terms of the clinical and radiological outcome as well as the complication rate of short stem THA, data on its use in obese patients is still rare and not sufficiently conclusive. Some studies have found no evidence of increased subsidence in obese patients, while other studies have shown contrary trends. In this context, the aim of this study was to investigate the relationship between BMI, postoperative subsidence and clinical outcomes in the setting of short stem THA.
