I had a MRI about a year ago and ortho surgeon said its chondromalacia.
Ahh, chondromalacia, my specialty (at least as a victim).
I was shut down for 10 yrs by same. Now have it totally beaten.
The standard advice is to strengthen the quads. The exercises I was given (sitting knee extensions with weights on my foot) damaged the knee faster than they delt with the problem and I had to devise my own exercises.
What I chose was an exercise called "kneecap raising" (described in a medical book as a post-old-style-knee-surgery exercise). I realized that it would strengthen the quads with essentially _no_ wear and tear on the kneecap joint surfaces. A kneecap raise is very simple--it is an isometric contraction of the quads done with the the knee straight the entire time. I did it standing up. Standing on straight legs with my feet separated by a foot or so, I just attempted to hyper-straighten the leg using only the quadracep muscles. (After a bit of practice, I learned to simply think of contracting the quads.) 20 seconds on and 20 seconds off for 10 reps. Start gently (otherwise you can strain the quadraceps tendon) and build up slowly. Do both legs to stay balanced. (I did both legs simultaneously.) Do every other day (standard advice for power building exercies--every day can cause overtraining and weaken the muscles).
By varying one's standing position, one can emphasize the different quadracep musles. Bending forward "turns off" rectus femoris (which
also crosses the hip joint). Twisting one's body side-to-side (which rotates the legs relative to one's body) alternately emphasizes vastus lateralis and vastus medialis--both very important for stabilizing the the kneecap.
After I built a base of strength, I then started walking up and down small hills (200 ft--small enough not to cause pain, big enough for a workout), initially with no weight on my back and then building up to 45 lbs. I don't even think about the chondromalacia any more.
Also, once the quads were built up enough by the kneecap raises, I was able to do the sitting knee extensions with weights with no problems.
The entire process took 6mo to a year for me. I have no idea if you can do it faster.
At no time did the above procedure cause me any pain. If it hurts, you are probably doing something wrong. And if you do get pain a while after doing the exercises, ice it down ASAP to limit the swelling.
Standard disclaimer:
I have no fromal medical training, and of course one cannot properly treat medical problems over the web. There may be other causes of chondromalacia than weak or unbalanced quadraceps. I srongly suggest you check out the above procedure with your doctor or PT before trying it.
BTW, I have discussed this procedure with a friend orthopedic surgeon. He knew about it. My doctors did not. So it would seem that some do know and some do not...
Good luck with it,
Doug
