what is a torn patella tendon

A torn patellar tendon is a complete or partial tear of the tendon that runs from the patellas inferior pole to the tibial tubercle. It is typically seen in males in their third or fourth decade of life and tends to result when a weakened tendon is placed under high tensile forces. A patellar tendon rupture requires prompt diagnosis and surgical repair as the patellar tendon is a part of the extensor mechanism of the knee, which is crucial to the function of the lower extremity. Symptoms of a patellar tendon tear include a ripping, tearing, or popping sound, bruising, swelling, and the inability to support your weight or having the knee buckle when walking. Surgical repair involves reattaching the torn tendon to the kneecap, and people who require surgery do better if the repair is performed soon after the injury. Physical therapy is also necessary afterward to regain full knee function.
