Correction of Acquired Leg Length Discrepancy after Hip Resurfacing Arthroplasty by Revision Resurfacing

Abstract

Case: A 53-year-old man presented with a 13-mm leg length discrepancy following left hip resurfacing arthroplasty (HRA), resulting in pain and imbalance. Advanced osteoarthritis of the contralateral hip was also noted. The patient strongly preferred HRA over total hip arthroplasty. Adequate remaining bone stock and the ability to resurface the contralateral hip allowed for resolution with 2 HRAs. Conclusion: This is the first known revision of a HRA with a subsequent HRA. Assuming sufficient bone stock and precise implant positioning, resurfacing presents a feasible methodology to overcome complex anatomical deformities and improve mobility.
