Acute inferior dislocation of the patella is a rare presentation in trauma and orthopaedics. Type II is caused by direct upward force on the inferior pole of the patella when the knee is flexed impacting the superior pole osteophyte into the intercondylar notch. Impaction in the femoral trochlea is rarely reported. A 92-year-old lady presented with locked knee held in 85° of flexion with an abnormal knee contour. Radiographs demonstrated that the upper pole of the patella was impacted in the femoral trochlea with a fracture of a superior pole osteophyte. The extensor mechanism was intact. Closed reduction is achieved under strong opioid pain relief. The patient returned to her baseline knee function within 6 weeks. Closed reduction of an inferior patellar dislocation in elderly patients is aided by superior pole osteophyte fracture and facilitates early mobilization, and avoidance of general anaesthesia.

Dislocation Of The Patella

Horizontal intra-articular dislocation of the patella is a very rare traumatic entity. We present an unusual case of horizontal intra-articular dislocation in which the patellar articular surface was facing upwards besides having an avulsion of the quadriceps tendon from the superior pole. There was associated posterolateral knee subluxation, which has not been described with intra-articular dislocation of the patella. A 20-year-old man presented with open patellar dislocation and locked knee after a roadside accident. The patient was managed successfully by open reduction and repair of the quadriceps tendon. There was buttonholing of the medial femoral condyle through the medial retinaculum leading to irreducible dislocation. A special reduction manoeuvre was employed to bring the knee to its normal alignment. Knowledge of this injury pattern is of utmost importance for proper recognition and appropriate allocation of the surgical technique.
