Knee replacement surgery involves the removal and replacement of damaged bone and cartilage around your knee joint with prosthetics. During surgery, the bone is prepared for the placement of these prosthetics, the prosthetics are positioned and placed, and a spacer is placed between the prosthetic components to enable a normal gliding motion. In some cases, the undersurface of your kneecap is also resurfaced with a plastic button.
You may receive either a total or partial knee replacement surgery. A total knee replacement surgery involves capping the ends of the knee joint bones and kneecap with plastic or metal prosthetics. A partial knee replacement removes injured tissue and bone only from certain areas of the joint, replacing these parts with prosthetics and preserving more natural tissue. Which procedure you’re recommended for will depend on the severity of your symptoms and your medical history.
At Orthopedic Specialists of New York, knee replacement surgeries are also performed using Mako, a robotic surgical assistant that helps our doctors conduct your procedure more effectively. Mako allows a surgeon to plan your procedure with a detailed 3D model. Its robotic arm also assists your surgeon’s precision, reducing the amount of cutting required to complete your surgery and preserving more of your healthy bone.
Generally, either type of knee replacement surgery is a treatment for various forms of arthritis, including osteoarthritis, rheumatoid arthritis, and post-traumatic arthritis.
Knee replacements are often reserved for patients suffering from severe pain who haven’t found an adequate degree of relief from less invasive treatments. Surgery may also be the right choice for you if you’re experiencing knee deformities such as bowing.
Knee replacement surgery is often performed for patients aged 50 and older, but people of all ages may be suitable candidates for the procedure. The only factors taken into consideration when recommending you for surgery are the level of pain and disability you’re experiencing.
For most patients, knee replacement surgery can relieve pain and restore mobility for up to 15 years, and regular daily activities can be resumed within two months of completing the procedure. Additionally, you can engage in low-impact physical activities like jogging and biking after recovery. High-impact activities like competitive sports, however, are not recommended.
