question: thankyou...I had total knee replacement in July this yr.  all has been going fine until about a wk. ago when i developed a terrific pain n the knee...causing aching down in the calf.  I went my  orthopedic Dr. after x-ray and he said i pulled a ligament...now i cannot bend the knee to get up with out severe pain and I cannot bend the knee back, like I have able to.  Is this tipical for pulled tendon?  There is nothing wrong with the prothesis.
