Interesting Don,

I had a Medial Minesectomy for torn cartiledge (spelled wrong / years ago before Arthroscopic Surgery) and they have told me NOT to ride a bicycle because I have no cartiledge - bone on bone. I do isometric type exercises to keep my hamstrings and quadriceps strong.

Colleen - the treatment options are incredible today. Just do the physcial therapy and you will be back on your feet in no time.
