Hi Bill,
I was about 60 degrees pre surgery and had been for some years. My surgeon said he cant really say what sort of rom i'll get back and didnt give me any 90 degree restriction as he said i would be able to get past 90 degrees. He was right! At 6 weeks i was stuck on 90 degrees and this was despite having physio twice per week a the hospital and me doing stretches every day, trying to pull my knee up to my chin whilst lying on my back, these really really hurt!
At 6 weeks i joined a gym and used a recumbent bike, i think this has helped the most as i could i could slowly raise the seat more and more pushing my leg up closer to my chest. Other exercises i'm doing are ;
Putting your operated leg up on a chair and leaning down and forward
Using a chin up machine, putting my leg up on the platform you stand on and using about 20kg weight let the machine lift my leg up raising my knee towards my chest
Doing squats both 2 and 1 legged in the shallow end of a pool (The water and buoyancy really help)
Lying on my back getting my 7 year old to push my leg up towards my chest!
It seems to be 2 steps forward and 1 back and it a very long and frustrating process and i agree it has to be done everyday or every other day, but i am making headway. At the moment (10 weeks post op) id guess I'm over 100 degrees and hopeful that i can get to the 120 degree mark.
Obviously the above are my exercises and seem to work for me but get a physio to check out what would be good for you.
If you have any questions give me a shout
Cheers
Nigel
