Before the knee replacement surgery, the orthopedic doctor will diagnose the condition of the knee. The doctor will inspect for tenderness, swelling, and pain in the knee. The doctor will also try to push and pull the knee joint and evaluate the damage in the structure of the knee. To diagnose the condition of the knee and the severity of the damage, the doctor may recommend an x-ray, ultrasound, CT scan and MRI.
Not every knee injury needs surgery. In case surgery is required, the doctor will choose the best method out of the following:
1. Partial knee replacement surgery - In partial knee replacement surgery, the orthopaedic surgeon replaces only the damaged part of the knee and replaces it with metal and plastic parts. The surgery is performed through minimal incisions and healing is usually risk-free.
2. Total knee replacement surgery - In a total knee replacement procedure, the damaged bone of the knee including the cartilage, kneecap, shinbone is removed. The removed part is replaced with an artificial joint made of high-grade polymers and metal alloys.
3. Arthroscopic surgery - In this surgical treatment, the surgeon makes a tiny incision and inserts an arthroscope, a tiny camera, into the knee. The doctor views the inside of the knee joint on a monitor screen. With the help of the guiding images, the doctor removes and replaces the damaged parts of the knee.
