@Mrfunkedude My doctor sent me to PT about my knees without even ordering any preliminary imaging or diagnostic. I'm not happy about that. I went for the 12 sessions, then finally got a referral to an orthopedist who ordered the MRI and asked me to continue the PT anyway, since it seemed to be helping. The MRI eventually showed that the cartilage under the kneecaps had disappeared, causing the bone-on-bone. The PT helped in that strengthening my quads pulled the kneecap back up into place.
