Abstract
We present a case of superior dislocation of the patella trapped by interlo cked osteophytes. Unlike previous reports, in which the mechanism resulted from a blow to the inferior pole, it is postulated that increased load on t he extensor mechanism, combined with patella alta and patellofemoral osteop hytes, caused locking of the knee in extension.
