There was a higher failure rate, especially with a modular exchange, with the implantation of a focally constrained liner in revision total hip arthroplasty, according to study results.
Researchers identified 58 patients who underwent revision total hip arthroplasty (THA) with a focally constrained liner. There were 19 hip reconstructions concurrently performed with an acetabular component revision and 39 hips had a well-fixed acetabular shell. The mean number of ipsilateral hip surgeries prior to revision THA was 4.2. Investigators analyzed clinical outcomes, redislocations and revisions at a mean follow-up of 3.5 years.
