- Torn meniscus, tendonitis, and bursitis.
- Quadriceps tendonitis.
- Entrapment of the lateral femoral cutaneous nerve.
- Iliotibial tract friction syndrome.
- Chondromalacia patellae – more common in runners.
- Patellofemoral dysfunction
- Sudden eccentric contraction such as stepping into a hole, stepping off a curb, or stumbling.
- Exercising such as deep knee bends.
- Immobilization of the knee from a cast or brace can activate TrPs and cause a pain complaint after the device is removed.
- Direct trauma to the muscle as the result of a fall sideways and striking the muscle on a piece of furniture.
- Sitting with the knee fully extended.
- Avoid overload by learning to correctly pick up heavy objects from the floor which will spare the quadriceps as well as the paraspinals (back muscles).
- Deep knee bends and full squats should be prohibited as so not to overload the quadriceps. A partial squat, however, is relatively safe if the thigh does not drop lower than the horizontal position, which would be parallel to the floor.
- Correct Morton foot structure.
- A tennis ball may be used by a person to treat their TrPs by laying on the side and placing the tennis ball between the outer thigh and the surface of the bed/floor.
