Knee joint arthroplasty (knee replacement surgery) is the replacement of the knee joint cartilage with an artificial metallic joint due to wear or damage due to idiopathic, rheumatic diseases, traumas, joint infections in childhood and adulthood, or metabolic diseases. Knee prosthesis surgery is aimed to increase the patient’s mobility and get rid of the pain.

Which patients are undergo replacement surgery?

Knee replacement surgery is not the best method for all patients. For this reason, the patient’s history is listened in detail while making the decision for surgery. However, the patient’s age, lifestyle, and physical mobility are also effective in resolving surgery. If the non-surgical treatments or alternative methods can be applied in accordance with the patient’s complaints, the first choice is usually not surgical intervention. However, the most effective method is to perform knee replacement surgery in cases where the patient does not get rid of the pain and restriction of movements cannot be prevented by methods such as medical treatment and physiotherapy.

Stages of Knee Prosthesis Surgery

In the preoperative period, consultations are held with the appropriate branches, and the resulting procedures are reorganized in accordance with the operation. If the patient is using blood thinners, the drugs are discontinued in a controlled manner before the operation and the use of the drug is started in a controlled manner after the operation. Patients are hospitalized on the day of surgery or the night before the preparations. Absolute pain control is provided in the postoperative period. On the first postoperative day, the patient should mobilize, stand up and walk. The hospital stay is 4-5 days and the patient is rehabilitated and made ready for home.

After Knee Prosthesis Surgery

After knee arthroplasty, patients should be as active as possible in the home. The recommended and taught exercise programs must be strictly followed. Routine checks should be done. If movement limitation is detected in these controls, the patient should be referred for rehabilitation. The aim of the postoperative period is to achieve a maximum painless range of motion.

How Many Hours Does Knee Replacement Surgery Last?

Knee replacement surgery usually takes 1-2 hours. The duration of the surgery may vary depending on the arthrosis and deformation of the knee joint.

Complications After Knee Replacement

After knee replacement surgery, as in any surgical operation, there is a risk of complications. Postoperative infection, deep vein thrombosis, risk of embolism are present. (Preoperative prophylaxis is carried out to minimize risks). In the later period, although infection may still occur, the weakening of the prosthesis and wear may occur over time. However, the expected life of the prosthesis is up to 15-20 years. The life of the prosthesis may vary depending on the patient’s physical activities, bone quality, and body mass index.

Postoperative medications prescribed by the doctor, good rehabilitation and avoiding movements that require attention will reduce the risk of complications related to prosthesis and surgery.
