Osteoarthritis (arthritis) is the wear and tear of weight-bearing joints due to ageing. Osteoarthritis starts in the cartilage and affects the bone under the cartilage, the joint capsule and the ligaments around the joint. There is even thinning and hardening of muscles that cannot be used due to pain. The knee is one of the most weight-bearing joints of the body and therefore one of the joints most affected by arthritis.

Osteoarthritis mostly starts from the joints on the inside of the knee and affects other joints. However, three joints in the knee are usually affected together.

Gonarthrosis occurs in middle and old age. It is more common in women over 50 years of age. The disease can also occur at an earlier age. Patients are usually overweight. The most important causes are previous joint operations, traumas, sports injuries, inflammatory rheumatism and some congenital disorders.

Knee arthritis occurs as a result of wear of the cartilage structures in the knee. Cartilage structure deteriorates due to reasons such as genetic predisposition, excess weight, rheumatism and trauma.

Patients whose pain-free walking distance falls below 300 meters due to arthritis and whose pain increases at night need knee replacement surgery.

After knee replacement surgery anesthesia, an incision is made to access the knee joint. Worn cartilage tissues are cleaned and removed and suitable prosthetic parts are placed. The surgical duration of the surgery is between 45 minutes and 1 hour. It takes an average of 2 - 2.5 hours to enter and exit the operating room.

Patients are walked one day after surgery. One or two days after the surgery, we let our patients go up and down the stairs.

The life of the implanted prosthesis lasts an average of 25 years. This period may vary depending on weight status and use of the knee.

The average surgical scar is 15 cm. Since aesthetic stitches are applied, there is no need to remove stitches. After discharge, dressing needs to be done every 3 days.

The patient, who is operated on by an experienced team due to knee arthritis, is followed up in the hospital for an average of 2-3 days. The necessary medications will be administered to you by the nurses to ensure that you go through the post-operative period with minimal pain. On the day of surgery, your x-rays will be taken and the prostheses placed on your kneecap will be evaluated radiologically by our team and you will be informed.

After the surgery, your pain will largely disappear. Over time, as your body gets used to the prosthesis, you will have a completely painless knee joint.
