Knee Replacement

What is a knee replacement?

A total knee replacement, or total knee arthroplasty, is a procedure for patients whose knee pain is restricting their ability to perform everyday activities. During the surgery, damaged bone and cartilage are removed and replaced with artificial implants. The ends of the femur and tibia are resurfaced with metal components, and a high-grade plastic liner is inserted between them to allow for smooth knee movement. If the cartilage of the kneecap is damaged, it is also resurfaced during the procedure.

Do I need a knee replacement?

Knee replacement surgery is usually recommended for patients with knee pain and reduced function who have not improved with non-surgical treatments such as physical therapy, medications, or injections. The most common reason for a knee replacement is osteoarthritis, which causes cartilage damage and inflammation, resulting in pain, stiffness, and mobility issues. Other conditions that may require knee replacement surgery include:

  • Trauma

  • Rheumatoid Arthritis

Do I need a partial or a total knee replacement?

Patients needing knee replacement surgery may receive either a partial or total knee replacement. If only one part of the knee is damaged, Dr. Kendall may recommend a partial knee replacement, preserving the healthy tissue in other areas, which can lead to a more natural-feeling knee. However, if two or more areas are affected, a total knee replacement is advised to address all the problematic areas.
