A knee replacement or knee arthroplasty is done to treat chronic knee pain and instability due to arthritis. In severe cases, a total knee replacement may be advised by your orthopaedic surgeon to enhance mobility and reduce pain.
A total knee replacement is done under general anaesthesia. Through an incision made in the front of the knee, the damaged cartilage and bone are removed. The thighbone and shinbone are then prepared for the prosthetic components. Once cemented in place, the prosthetic kneecap is fixed into place before closing the incision.
After surgery, rehabilitation, physical therapy, and any lifestyle changes that might be required will be discussed with you. Normal activities can be resumed in the next 6 weeks.
