Background
This study examines how cam overresection during femoroplasty affects functional outcomes in revision hip arthroscopy. Overresection could damage the labral seal and hinder recovery.
Methods
Patients undergoing revision hip arthroscopy were classified into three groups based on femoroplasty accuracy: overresection (OR), underresection (UR), and neutral resection. Functional outcomes and conversion rates to total hip arthroplasty (THA) were analyzed.
Key Findings
The OR group had significantly worse preoperative and postoperative scores compared to the UR group. Over 30% of OR group patients required conversion to THA, whereas none of the UR group patients did.
Conclusions
Cam overresection negatively impacts hip function and increases the likelihood of requiring THA, emphasizing the need for precise femoroplasty during surgery.
What Does This Mean for Patients
Overresection during femoroplasty could lead to inferior outcomes and a higher chance of needing THA, highlighting the importance of careful surgical planning.
