Some risk factors (things that increase your risk) for patellar tracking disorder are beyond your control. Others, such as having weak quadriceps, you can change.
Things that you cannot change
- Family history of knee problems.
- Knee abnormalities, such as knock-knees, a shallow femoral groove, a small or flat patella or an excessively long patellar tendon that allows the patella to slide too high on the knee joint (patella alta).
- A poorly healed injury of the hip, leg, knee or foot.
- Previous kneecap dislocation.
- Previous knee surgery.
- Generalized ligamentous laxity, or "loose-jointedness."
- Damage to cartilage.
Things that you can avoid or change
- Weak thigh muscles (quadriceps).
- The outer part of your thigh muscle is stronger or contracts quicker than the inner thigh muscle.
- Tight ligaments, tendons and muscles.
- Excessive body weight.
- Running, particularly on hills.
- Playing sports that require repeated jumping, knee bending or squatting.
- Improper footwear.
- Improper technique and/or lack of adequate training for sports or other activities.
