Knee Replacement Defined

Chronic pain in the knees can be caused by arthritis, a fracture, break or a medical condition which has weakened your joint. If the pain in your knee is not helped by anti-inflammatory tablets and it is increasingly difficult to perform everyday activities such as standing, bending and light walking, knee replacement surgery might be the treatment option you need.

Knee replacement surgery works by removing the damaged, diseased cartilage, tissue and bone that forms the knee joint and replacing the bone with a prosthesis made from metal, ceramic or plastic.


Knee Replacement Procedure

Knee replacement surgery is performed under general anesthesia. The skin on the knee is cut to expose the cartilage and bone and the surgeon removes the damaged tissue and cartilage around the bone. The damaged part of the knee joint is removed. The surgeon will prepare the knee to secure the prosthesis. The prosthesis, made from metal, porcelain or plastic depending on the surgeon and the need of the patient. The new knee is secured to the thigh, shin and knee cap.

Knee replacement surgery may now be performed using minimally invasive surgical techniques, allowing the surgeon to perform surgery through a smaller cut, however few orthopedic surgeons have adopted this technique until the long-term results of MIS knee surgery are clear.

Recovering From Knee Replacement

Patients are encouraged to begin using their new joint the day after surgery and will be provided with physiotherapy exercises to complete. Within a month the patient should have recovered and be feeling the complete benefits of the knee replacement surgery.

Cost Of Knee Replacement

The cost of knee replacement varies depending on the location of your treatment and the type of material used to replace the joint.
