You are doing good for 6 weeks. You had asked about numbness a few posts back. My tkr was 6 months ago and I am still numb on the outside of my knee. The inside is waking up there and I wish it wouldn't! I'm getting zingers like crazy there. My quad areas took a while before the pain subsided, but now it's almost completely gone. The only time I feel it is if I've over done. My ROM was slow coming, but I didn't let it bother me. I knew my knee would improve on it's own. I also saw that you quit PT. Good choice. I never did any for any of my 11 surgeries. Now, remember to not overdo and continue to follow the BS way. It is a proven method that works!
