Intra-Articular Patellar Dislocation

Arthroscopic treatment of femoral trochlear notch fracture caused by intra-articular dislocation of the patella

“…Type I dislocations are usually present among adolescents (14,17). The horizontal type of dislocation occurs when the victim falls down onto the over-flexed knee and the proximal pole of the patella wedges into the femoral trochlear notch (6,7,17,19,20). Our case patient had dislocated in the aforementioned way, however, this is the first case in which the wedging caused an impaction fracture of the femoral trochlear notch.…”

Horizontal Inferior Patellar Dislocation in an Elderly Patient: A Case Report and Review of Literature

“…Others have stated that it could be performed without anaesthesia [12] or with the use of sedatives alone [3] [7] [11] [13]. Various reduction techniques have been reported, such as knee extension after flexion [14] or tibial traction to push the lower pole of the patella upward from below [11] and pressing downwards on the upper patellar pole while extending the knee [15].…”

“…There are several case reports in the literature regarding locked arthritic knees. Simple methods of manipulation and immobilization were recommended for the management of inferior patellar dislocations in elderly patients [14]. Current literature recommendations for recurrent and irreducible dislocations are open reduction and exploration; however, such procedures may lead to longer recovery duration [6] [8].…”
