Hi I had total knee replacement on Sept 18, 2008. The surgery went well but I'm having trouble with my rehab. I have been in thearpy for 3 weeks now and can not regain my range of motion. I have reached 65 degrees and can not get any further. My physical thearpist has suggested I have a manipulation done but I am not sure. I have followed all my excercises regularly and have no idea as to why I cannot regain my ROM.
