Kneecap dislocation - Symptom

Alternative Names

Dislocation - kneecap; Patellar dislocation or instability

Symptoms:

  • Kneecap (patella) moves to the outside of the knee
  • Knee pain and tenderness
  • Knee swelling
  • "Sloppy" kneecap -- you can move the kneecap excessively from right to left (hypermobile patella)

The first few times this occurs, you will feel pain and be unable to walk. However, if dislocations continue to occur and are untreated, you may feel less pain and have less immediate disability. This is not a reason to avoid treatment. Kneecap dislocation damages your knee joint.
