Pain just below the right knee cap (just to the outside of center), on the bone, while under strain like squatting down. Pain is accompanied by a loss of strength from the leg being bent 135 degrees through about 170. Standing without assistance or using the other leg for most of the work is impossible. Tightness around the knee during rest and most of the time pressing on the area feels like pressing on a bruise. My feet turn out severely. Had MRI, Ortho surgeon sees no issues in the knee.
