Radiocapitellar arthroplasty

This article sets out the evidence demonstrating that the clinical need for a prosthetic arthroplasty designed specifically for the radiocapitellar joint has been underestimated. The prevalence of radiocapitellar degenerative change requiring treatment is discussed and the relationship between 'isolated' radiocapitellar joint arthritis and more generalised elbow arthritis is explained. Current literature now supports our view that radiocapitellar joint arthroplasty is not only an effective long-term solution for patients with localised radiocapitellar arthritis but also for those patients with more severe degenerative changes involving the elbow joint irrespective of their cause. We consider that is important to avoid resection of the radial head and therefore that resurfacing implants rather than joint replacement implants are more likely to provide a good longterm outcome for patients with elbow arthritis.
