Total Joint Specialists
This research is being done to determine whether removing or preserving the acetabular labrum, a ring of cartilage around the hip socket, during hip replacement surgery affects post-operative outcomes, operative time, or ease of placing the hip implant. Both techniques (labrum removal and labrum preservation) are commonly performed by surgeons during total hip arthroplasty (THA). However, there is no definitive evidence showing whether one approach is better than the other. The goal of this study is to compare recovery and surgical factors between these two routinely used methods.
Inclusion Criteria: * Age ≥ 18 years. * Indication for primary unilateral total hip arthroplasty for osteoarthritis (Tonnis grade ≥2 or surgeon's standard indication). * Able to provide informed consent and complete PROMs in English (or validated local language instruments). Exclusion Criteria: * Prior ipsilateral hip replacement or resurfacing. * Active infection or inflammatory arthritis where labral management is judged by the surgeon to be non-standard. * Severe acetabular bone loss or deformity requiring custom implants or complex reconstruction (Crowe III/IV dysplasia). * Planned simu…
The acetabular labrum will be left in place during surgery unless it physically prevents proper implant seating, in which case it may be trimmed as necessary.
The acetabular labrum will be removed during surgery, prior to final cup placement.
