For years i have had Petella Fermial diseas in my knee caps (rare disease that leaves calcium deposits behind the knees, grinding in the socket). I played catcher last year and was fine, in the off season i began feeling instability in my left knee, that feels like a problem with the ACL or MCL.
Back playing baseball now, ive been hampered by weakness in my left knee, without any pain at all. To describe it, would be it feels like my knee is filled with cotton, but to reiterate no pain at all.
When i get up from sitting and plant on it, it feels as if my tendons are getting squeezed.
Does this sound like a major problem that i should get checked out, or is there something i can do workout wise to strengthen, or to alleviate the instability.
Keep in mind on my right leg and ankle i destroyed it 4 years ago and i have had 3 surgeries and have a steel plate and 6 screws in my ankle to lower leg.
