Knee replacement surgery has become a key solution for individuals struggling with chronic knee pain and limited mobility—conditions often caused by cartilage deterioration in the joint. With more than 6,000 joint replacement procedures performed annually in Israel, the demand for this intervention continues to grow as conservative treatments such as medication, physical therapy, and lifestyle changes prove insufficient for many patients.
The primary goals of knee replacement surgery are to reduce or eliminate persistent pain, restore joint function, and enhance overall quality of life. This procedure is particularly beneficial for patients whose daily activities are significantly impacted by stiffness, inflammation, or joint instability.
As part of this project, data were collected from 382 patients who underwent elective knee replacement surgery at Sheba Medical Center. Participants were asked to complete the KOOS-PS questionnaire, which measures physical function, prior to surgery and again at three months, six months, and one year following the procedure.
The Outcomes
Based on data collected between 2019 and 2024, the results indicate that among patients who rated their preoperative condition as moderate to severe, 78% reported a significant clinical improvement approximately six months after surgery. Meanwhile, 19% experienced a decline in their baseline condition, and 3% reported no noticeable change.
