Orthopedic surgeons in the Sutter Health network use the latest technologies to perform partial and total knee replacement surgeries (also called knee arthroplasty). These surgeries replace the ends of the thighbone and shinbone with implants made with a medical-grade plastic called polyethylene and alloys of cobalt chromium and titanium. The new joint has a plastic spacer in place of cartilage so it can move smoothly.
If you’ve tried nonsurgical alternatives but you’re still dealing with injury or severe arthritis, these common surgeries can help ease pain and restore mobility. Most people spend one to three nights in the hospital after surgery, but outpatient surgery is possible if you’re healthy, strong and have support at home. Most knee replacements last at least 20 years.
