Injury to the anterior cruciate ligament is a devastating injury for athletes of all ages. Treatment usually involves surgery. If you undergo surgical reconstruction, you may have to choose between using your own tissue or using a donor graft.
The quadriceps tendon is a thick, strong tendon that can withstand tremendous force. In daily life, it acts as part of the extensor mechanism to straighten the knee. People who injure the extensor mechanism may tear the quad tendon, tear the patellar tendon, or fracture the kneecap. All of these injuries have similar treatments and rehabilitation plans.
