In recent years, the prevalence of joint replacement surgeries, particularly knee replacements, has surged, with over 6,000 procedures performed annually in Israel alone. Knee replacement surgery aims to mitigate or eliminate pain caused by cartilage wear and tear within the knee joint, while also enhancing flexibility, mobility, and overall quality of life.

The knee joint comprises four crucial bones – the thigh, calf, tibia, and patella – interconnected by muscles, ligaments, and tendons. Its primary function is to facilitate movement while supporting the body’s weight. Resembling two wheels on a flat surface, the knee’s inherent instability renders it susceptible to soft tissue injuries. The cartilage, a pivotal component, envelops the knee joint bones, absorbing shocks and ensuring seamless movement. However, when the cartilage deteriorates, bones rub against each other during movement, leading to discomfort, restricted mobility, and pain.

In a comprehensive study conducted at Sheba, data from over 200 patients who underwent elective knee replacement surgery were analyzed. Participants completed a pre-surgery questionnaire (KOOS-PS) to assess their functional status, with follow-up assessments at three months, six months, and one year post-surgery.

Examining data spanning from 2015 to 2023, compelling results emerged. Notably, among patients reporting moderate to severe pre-surgery health conditions, 80% experienced significant clinical improvement approximately six months post-surgery. Conversely, 17% observed a decline from their baseline condition, while 3% reported negligible changes.

The insights gleaned from patient outcomes underscore the procedure’s efficacy in enhancing overall well-being and functionality. As such, continued research and advancements in this field are crucial for further improving patient outcomes and quality of life.
