PATELLA TRACKING INSTABILITY
ANATOMY
The knee joint is a hinge that joins the tibia and fibula (lower leg bones) with the femur (thighbone). The patella is held in place in the front of the knee joint by tendons on the top and bottom and by ligaments on the sides. A layer of cartilage lines underneath the patella, helping it glide along the groove at the end of the femur.
MECHANISM OF INJURY
Patellar tracking instability occurs when the patella (kneecap) shifts out of place as the leg bends or straightens. In most cases, the patella (kneecap) shifts too far toward the outside of the leg, although in a few people it shifts toward the inside.
SYMPTOMS
- Discomfort or pain, especially when you go down stairs, sit for a long time; stand up from sitting, or squat.
- Popping, grinding, slipping, or catching of the patella (kneecap) may be felt when you bend or straighten your leg.
- A buckling or giving way sensation may also be felt.
TREATMENT
Please consult with your medical professional for a complete diagnosis and treatment plan.
