Knee replacement surgery is a medical procedure designed to alleviate pain and restore function in individuals suffering from considerable knee damage, often due to arthritis or injury. In the course of the surgery, the impaired joint surfaces are excised and substituted with artificial parts, which can greatly enhance mobility and overall quality of life. Patients usually go through a comprehensive assessment to establish their eligibility for the surgery, and rehabilitation following the operation is essential for effective recovery and the restoration of strength in the knee.
