Patellar Tracking Disorder - What Increases Your Risk

Some risk factors for patellar tracking disorder are beyond your control. Others, such as having weak quadriceps, you can change.

Risk factors that you cannot change

  • Family history of knee problems.
  • Knee abnormalities, such as knock-knees 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.

Risk factors 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 athletic training or technique.
