Articular hypermobility and chondral injury in patients with acute patellar dislocation

Abstract

Thirty adolescents with acute, primary patellar dislocation were assessed for a relationship between articular hypermobility and chondral injury. The 15 patients without articular hypermobility had a 2.5 times increased frequency of articular lesions when compared with 15 patients with hypermobility. Assessment of articular hypermobility should be part of the examination in patients with patellar dislocation.
