Brian P. Chalmers, MD,  hip  and knee surgeon at HSS, presented at the American Association of Hip and Knee Surgeons annual meeting on a study indicating proximal femoral replacement may be an effective salvage option in complex revision total hip arthroplasty cases.

“It is important to try to do everything we can to mitigate the common causes of re-revision in these complex patients,” said Dr. Chalmers. 

Dr. Chalmers and colleagues retrospectively analyzed data for 49 patients (50 hips) who underwent revision THA to evaluate the survivorship of proximal femoral replacement. The mean follow-up was 5 years, with a minimum follow-up of 2 years. Dr. Chalmers measured included all-cause reoperation, all-cause re-revision, survivorship free from dislocation and risk factors for poor outcomes.

Outcomes measured included all-cause reoperation, all-cause re-revision, survivorship free from dislocation and risk factors for poor outcomes. Dr. Chalmers said survivorship free from all-cause reoperation was 78% at both 2 and 5 years. In addition, he said survivorship free from all-cause re-revision was 87% at 2 years and 82% at 5 years. Survivorship free from dislocation was 84% at both 2 and 5 years, according to Dr. Chalmers. He said indications, bearing designs, as well as construct length and body length ratios, were not found to be risk factors for reoperation. However, he noted there was a trend toward increased rates of dislocation in patients who had a standard or elevated liner vs. a constrained liner. Dr. Chalmers said 75% of patients who had a proximal femoral replacement with a standard or elevated liner sustained a dislocation.
