hey everyone had surgery yesterday for what they thought i had a medial torn meniscus..but when the surgeon went in he said nothing was torn...he said i have Tibial Femoral Arthritis which he scraped and said i had some cartliege that was peeling like an orange and flapping around....but i was way to out of it and didn't ask where this cartlige was....however today i am in excruitating pain behind the knee cap can't bend it without pain doing ice excersies etc...but it just seems to be getting stiffer and stiffer...i'm walking around the house to exercise it but is becoming painful...is this normal?? also when i walk it feels like my medial side wants to snap i get clicking when i bend to straighten it

You've just had surgery - you have to expect pain and swelling.
If you've been immobile for a while you have to expect some muscle atrophy - so expect lots of catching/crunching etc. Even a short period of immobility will cause your muscles to weaken and therefore things won't be the same.

As you've had surgery, i'm sure your OS has referred you to PT's who have given you some exercises to do, to help the situation - quad crunches etc. These PT exercises are very important, but also remember that you have had surgery and it is going to hurt.

All the best
