    I found this little blurb on exrx..

    http://www.exrx.net/ExInfo/Weaknesses.html#anchor13238820

    So if I read this right, then if I strengthen my VMO (Vastus medialis / tear drop muscle), then it will help prevent lateral patella dislocations?

    What are some VMO isolation exercises that you guys have done in the past?

    i did vmo isolation as part of physical therapy for patellar tendinitis.. after electrostim, heat, and stretching, they basically made me do regular exercises like leg presses and squats, while concentrating on using the VMO. at first i had a little device hooked up to the vmo that would make a sound to let me know when the VMO was being used. once i figured out how to fire off the VMO properly, the device was no longer needed.

    as i got stronger, then tweaked the exercises. i started doing one legged squats, followed by one legged squats on a trampoline or foam pads. i would also do leg presses utilizing both legs to press the weight up, then one leg to bring it back down.

    Interesting. So how were you concentrating on using the VMO while doing normal quad exercises?

    i can't explain it. you just kinda flex your quads and hamstrings really hard and the vmo fires.

    i'm sure ceaze could articulate it better than me.

    Found this info-
    In any acute PF problem it is important to reduce swelling before initiating strengthening type exercise because a swollen knee reflexly inhibits quadriceps contraction, causing atrophy and weakness.13 Attempting quadriceps strengthening when there is effusion and pain is a waste of time and effort. PF rehabilitation protocol by Brunet and Stewart14 includes isometric quad sets of 50 per hour, followed by straight leg raises (SLRs), eight sets of 10 lifts three times per day. The SLR are done with the noninvolved knee flexed to 90 degrees with foot next to outstretched involved knee. Patient contracts the knee muscles and raises involved leg up parallel with the uninvolved thigh. Patient holds for three seconds, lowers leg and rests for three seconds. Patient rests for one minute after each set of ten lifts. As soon as leg lifts become easy, free weights are added from one to fifteen pounds and added as soon as patients state that they are no longer fatigued.

    Hope it helps.
