Complications
By Mayo Clinic staffIf you try to work through your pain, ignoring the warning signs your body is sending you, you could cause further tendon damage and other complications, such as:
- Weak leg muscles. As your leg compensates for the pain in your knee, your thigh muscles (quadriceps) and calf muscles can weaken.
- Torn tendon. Your body can't keep up with the continued wear and tear on your tendon, leading to larger and larger tears in the patellar tendon.
- Chronic knee pain. Knee pain can persist if the factors contributing to patellar tendinitis are not addressed.
