Quadriceps Tendon Repair

The quadriceps muscles on the front of the thigh attach to the patella (kneecap) by the
quadriceps tendon. When the quadriceps tendon is injured, the quadriceps muscles and the
patella are no longer properly connected and this results in loss of function of the quadriceps
muscles. The quadriceps muscles work to straighten the knee or control the knee during
bending or squatting. A complete rupture of the tendon leaves a patient unable to fully
straighten the knee or walk normally without the knee giving out. The quadriceps tendon
usually is torn by a sudden episode of stressful over-activity such as jumping or falling.
Repairing the tendon back to the patella is recommended since the quadriceps tendon is
needed to walk normally and perform other daily activities.
