Abstract

Irreducible lateral patella dislocation is an extremely rare event, documented only a handful of times in the literature. Lateral patella dislocation is usually the result of indirect trauma and is usually easily reducible, often prior to seeking medical care. We present a case of a 50 year old man with an unusual case of irreducible lateral patella dislocation with associated rotation about the long axis requiring open reduction, in a knee with degenerative changes.
