Types of Knee Replacement Surgery

Knee replacement surgery, also referred to as knee arthroplasty can help relieve pain and restore function in severely diseased knee joints. The procedure entails removing damaged bone and cartilage from your thighbone, shinbone, and kneecap and replacing it with a prosthesis made of metal alloys, high-grade plastics, and polymers.

An orthopaedic surgeon evaluates your knee's range of motion, stability, and strength to determine whether a knee replacement is right for you. X-rays assist in determining the extent of the damage.

Depending on your age, weight, activity level, knee size and shape, and overall health, your doctor can select from a variety of knee replacement prostheses and surgical techniques. Aster Hospitals is one of the best orthopaedic surgery hospitals in Dubai.

Why does knee replacement surgery is done?

The most common reason for knee replacement surgery is to relieve severe osteoarthritic pain. Patients who require knee replacement surgery frequently have difficulty walking, climbing stairs, and getting in and out of chairs. Some people experience knee pain even when they are at rest. Consult the best orthopaedic surgeon in Dubai for more information.

Types

Total knee replacement

Total knee replacement surgery is the traditional method for repairing a damaged knee (TKR).

Doctors have significantly improved the procedure since the first operation in 1968. Indeed, medical technology advancements have resulted in precise and highly functional artificial knee implants that nearly duplicate the way the human knee moves — and are custom fit to your body. A TKR is now one of the safest and most effective standard orthopaedic surgeries available.

During a TKR, a surgeon removes the damaged surface of your bones caused by osteoarthritis or other causes and replaces the knee with an artificial implant customised to your anatomy.

Partial knee replacement

Partial knee replacement (PKR), also known as uni-compartmental knee replacement, is an option for a small number of people. In the United States, far fewer PKRs are performed than TKRs.

Only a portion of the knee is replaced, as the name implies, in order to preserve as much of the original healthy bone and soft tissue as possible. Candidates for this surgery typically have osteoarthritis in just one compartment of their knee. As a result, surgery is performed in one of three anatomical compartments of the knee where diseased bone causes the most pain: the medial compartment on the inside of the knee, the lateral compartment on the outside of the knee, or the patella femoral compartment on the front of the knee.

Minimally invasive surgery

A surgeon may recommend minimally invasive surgery (MIS) to reduce tissue trauma, pain, and blood loss, thereby speeding recovery. The incision is reduced to 3 to 4 inches with a minimally invasive approach. The kneecap is pushed to the side rather than turned over, which is a key difference between this approach and standard surgery. As a result, the quadriceps tendon is cut less deeply and the quadriceps muscle is less traumatised. Because the surgeon cuts less muscle, you will heal faster and have a greater range of motion after recovery.
