The knee is a type of hinge joint formed by the tibia (shinbone), femur (thighbone), and patella (kneecap). The ends of the bones in the knee joint are covered with cartilage, a tough, lubricating tissue that helps provide smooth, pain-free motion to the joint.
Osteoarthritis, the most common form of arthritis, is a wear and tear condition that destroys joint cartilage, and it typically develops after years of constant motion and pressure in the joints. As the cartilage continues to wear away, bone begins to rub against bone, causing the irritation, swelling, stiffness, and discomfort commonly associated with arthritis.
Dr. Roberts may recommend knee replacement surgery if you have significant arthritis. Surgeons don’t actually replace the joint as is commonly thought. They actually replace the damaged cartilage found at the ends of the bones in your knee joint. Perhaps it should be called “cartilage replacement surgery.”
Knee replacement implants to resurface the joint are typically made from metal alloy and polyethylene (plastic). The implants are designed to restore function and eliminate as much discomfort as possible while allowing you to return to a more active lifestyle.
Rehabilitation and walking begin the day after surgery, and the hospital stay is normally 3 to 4 days. Therapy will begin in the hospital and usually continues after discharge for approximately 6 to 12 weeks.
Knee Replacement surgery has been extremely successful in helping patients with arthritis return to their normal activities and relieve their discomfort.
