Medical Definition: Subluxation - The patella partially coming off of its track.
Dislocation - The patella entirely coming off of its track.
Causes: Patellar Subluxation may be caused by Iliotibial Band Syndrome, trauma-such as a twisting injury, or general malalignment of the patella. Patellar Dislocation is usually due to a traumatic injury - such as a blow to the knee.
Symptoms: Pain in the patellar region.
Recommended Treatment: R.I.C.E. - Rest, Ice, Compression, Elevation. Strengthening of surrounding muscles to help absorb shock to the knee. A proper stretching (Quadriceps, Iliotibial Band) routine is highly recommended pre and post workouts. Apply Ice for 10-15 minutes after each workout to reduce inflammation and pain. (If any skin irritation or adverse reaction occurs due to icing, see your medical doctor).
