It will be 2 years,for me May 9th that I've had knee replacement (Left) and knee still gets sore I do squats, I walk every other day, I bowl in League competition so why am I still sore ? Can't run anymore depressing at times, any suggestions?
Simples, you’re hurting because you’re doing too much, respect your knee.
We need to accept our new reality, after knee replacements. Be kind to your body and try Tai chi, yoga, pool walking etc. Running on a knee replacement could wear out the replacement too soon. Do you really want another, in a few years? Get some exercise advice from a professional physiologist, experienced with joint replacements. Good luck to you.
