Acute lateral patellar dislocation is relatively common in younger age group and most likely caused by indirect trauma. About 10% of acute patella dislocations are the result of a direct blow to the medial side. We report a case of irreducible lateral patellar dislocation which is of exceptional interest in that lateral patellar dislocation (extra-articular) occurred in comparatively older age ...

OBJECTIVE To evaluate the clinical and functional results of a surgical treatment of patellar dislocation whose etiology was iatrogenic quadriceps fibrosis in children. MATERIALS AND METHODS A prospective study was undertaken from February 2004 to December 2009. The study included 54 pediatric patients (56 knees) that had developed dislocation of the patella after repeated intramuscular injec...

Superior dislocation of the patella is a rare diagnosis, which usually occurs after a trivial trauma. It usually requires manipulation with analgesics or may even need anaesthesia. We report a case of spontaneous reduction of the dislocation, which lead us to believe that this may be more common in the community than has been reported.

Recurrent dislocation of patella may occur in patients with ligament laxity. Method of treatment in this condition is controversial but patellofemoral ligament reconstruction is the most accepted method. We present a patient with Rubinstein-Taybi syndrome and recurrent patellar dislocation who managed successfully by patellofemoral ligament reconstruction.

To our knowledge, this is the first case of synovial osteochondromatosis in a patient presenting with a double patella-like condition. The true duplication of the patella, which is called double patella, is extremely rare. In our case, the operative and histopathological findings showed that the double patella-like condition was secondarily induced by synovial osteochondromatosis. Synovial oste...
