Total knee arthroplasty for neglected patellar dislocation

Abstract

Neglected permanent post-traumatic patellar dislocation is rarely seen. In this group of patients, secondary osteoarthritis may develop within years, consequently, patients suffer from pain. In the literature, there have been a few cases treated with total knee arthroplasty. Although each surgeon's treatment plan changes, no standard surgical technique has been adopted. The aim in these cases, is to keep the patella located in the femoral groove and to achieve full knee extension. In this paper, a patient with osteoarthritis due to post-traumatic patellar dislocation who has undergone total knee arthroplasty is evaluated in the light of the literature.
