Knee Replacement

The Mass General Brigham knee replacement surgery teams are experts in leading surgical approaches and care for knee replacements. Together with you, our experts plan your care pre- and post-replacement to maximize your outcomes and recovery.

Center of excellence for knee replacements

Mass General Brigham is a distinguished center for knee replacement surgeries in the United States. Our joint replacement surgeons perform more than 1,000 knee replacement surgeries every year, with a 99% success rate for first-time knee replacement surgeries. 

Our knee surgeons collaborate with specialists like physical therapists and sports medicine practitioners to deliver comprehensive, customized care plans to every patient. We specialize in innovative approaches to knee replacement using the latest surgical techniques and new materials developed by our own engineering staff, such as custom 3D-printed knee implants, robotic surgical navigation and sophisticated imaging. On average, our knee replacement surgery patients report:

  • A 10-point improvement in knee pain and function three months after surgery
  • A 15-point improvement 12 months after surgery

Types of knee replacement surgeries

Total knee replacement (TKR) is performed in patients with severe wear and loss of knee cartilage due to injury, trauma, inflammation or various types of arthritis or other aging-related changes in the knee. In TKR, the worn cartilage is removed and replaced with a combination of metal and plastic implants.

In some cases, wear and tear of the knee, or arthritis, is confined to a single side of the knee. If our doctors determine this approach is appropriate for you, the damaged part of the knee will be replaced with metal and plastic while the healthy part of the knee is preserved. This is referred to as a partial knee replacement. Because a partial knee replacement is done through a smaller incision, the surgery is quicker, the hospital stay is shorter, and patients can rehabilitate and return to normal activities faster.

TKR implants have a typical life span of 10–20 years. Over time, the artificial components may wear out and need to be replaced in a revision (or redo) TKR procedure. Implants may also need replacement due to infection, pain or other factors as determined by your doctor. If you have had knee replacement and are experiencing pain or discomfort, our doctors can evaluate your case and help determine if a revision surgery is needed.
