Total knee replacement is a surgical procedure where worn, diseased, or damaged surfaces of a knee joint are removed and replaced with artificial surfaces. The metal that is most commonly used is an alloy of cobalt, chromium and molybdenum. The plastic is ultra-high molecular weight polyethylene.
Knee joint replacement may be recommended for:
1. Knee pain that hasn’t responded to other therapy (including medication, injections, and physical therapy for 6 months or more)
2. Total knee replacement surgery is considered for patients whose knee joints have been damaged by either progressive arthritis, trauma, or other rare destructive diseases of the joint

7. Some tumors involving the knee
PROCEDURE
There are three main components of an artificial knee joint – the femoral component (to replace the end of the femur), the tibial component (to replace the end of the tibia) and the patellar component (to replace the back of the kneecap) orthopedic in Thane. In total knee joint replacement surgery, all of these components are used.
The operation is performed under general anesthesia. An incision approximately eight inches in length is made on the front of the knee. The front (anterior) muscles are incised and the joint is exposed. The knee cap (patella) is moved out of the way, and the ends of the thigh bone (femur) and shin bone (tibia) are cut to fit the prosthesis. The undersurface of the knee cap is cut to allow the surgeon to place an artificial piece.The final components may be either cemented in place or press fit in a cementless manner.
During the operation, surgeons check the alignment of the knee as well as test function and stability of the knee joint. The knee is stitched closed, a sterile dressing is applied. A total knee replacement generally requires between one and one- half to three hours of operative time.
AFTER SURGERY
