Patellar dislocation occurs mainly in youths (under age 20) engaged in sports that may involve accidental rotation of the knee while in flexion, a movement clinically called valgus, which is the cause of some 93% of patellar dislocation cases. [3]
A knee dislocation is an injury in which there is disruption of the knee joint between the tibia and the femur. [3] [4] Symptoms include pain and instability of the knee. [2] Complications may include injury to an artery, most commonly the popliteal artery behind the knee, or compartment syndrome. [3] [4] [7]
Patellar tendon rupture can usually be diagnosed by physical examination. The most common signs are: tenderness, the tendon's loss of tone, loss of ability to raise the straight leg and observation of the high-riding patella. Radiographically, patella alta can be detected using the Insall and Salvati method when the patella is shorter than its ...

The knee dislocates towards the outside of the leg, leaving the MPFL torn. If the injury to the ligament is left untreated, it may be able to heal on its own, but likely in a loosened or lengthened position.
The bones of the knee are the femur, patella, tibia, and fibula. The fibula is on the lateral side of the knee and the patella has little effect on the medial side of the knee. The bony congruity of the medial knee consists of the opposing surfaces of the medial femoral condyle and the medial tibial plateau.
