I had a knee revision done in March on my right knee . Ever since I’ve had pain in my lower thigh above my knee . My physical therapist in my orthopedic doctor told me that it was most likely from the Turnock it used during surgery . Now the pain is gotten really bad I can barely walk on it and I have a lump above my knee on my lower part of my thigh what could cause this ?Hi, can I answer your health question?
