Kneecap dislocation

  • Alternative Names

    Dislocation - kneecap; Patellar dislocation or instability

    • Knee appears to be deformed
    • Knee is bent and cannot straighten
    • Kneecap (patella) dislocates to the outside of the knee
    • Knee pain and tenderness
    • Knee swelling
    • "Sloppy" kneecap -- you can move the kneecap too much 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.
