Clinical outcomes of conversion total hip replacements from previous hip fracture operations in the older population

Background Conversion total hip arthroplasty (THA) is a procedure performed to often address complications from previous hip surgery. The objective was (i) to compare primary THA with conversion THA, and (ii) to evaluate the clinical outcomes and complications of different types of conversion THA. Methods This was a retrospective study that included primary and conversion THA operated from 2020 to 2024, aged ≥50 years. Operative time, intraoperative blood loss, post-operative functional status, complication and mortality were evaluated. Results A total of 107 THA (51 conversion THA, 56 primary THA) in Chinese patients were evaluated. Patients with conversion THA were significantly older than primary THA. Comparing with primary THA, the conversion THA group had worse function. Mean operative time for conversion THA from hip screws was significantly shorter compared to conversion from other implants. Conclusion With proper patient counselling and patient selection, conversion THA is a treatment option for complications arising from previous hip fracture surgery.
