Dr. Liao performed a ROBOTIC total right knee replacement. This knee was totally worn out. it should have been replaced two years ago. The pain was 24/7 no relief at all. The surgery went well, not a great deal of pain at all. The day after surgery I was walking around the hospital ward like I had no surgery at all. I was discharged four days latter. I am single and all on my on, was able to take care of myself on a daily basic. With the aid of physical therapy weekly ,l improve daily . Well within fourteen days l have 97 degrees bend on my knee. Back in 1999 I had my left knee replaced the old fashion way and had put no weight on my leg after five days in hospital. To all out their that may be looking at knee replacement, l highly recommend ROBOTIC surgery, the pain level is less ,recovery time shorter, and quicker mobility. In closing, l would say don't wait ,stop the pain and get back to a normal life, through Dr. Liao ROBOTIC Knee Replacement, Great Surgeon.
