What is Total Knee Replacement?

Total knee replacement is a surgical procedure that involves replacing the damaged joint surfaces of the knee with artificial components. These components are typically made of metal and plastic, and they are designed to mimic the function of the natural knee joint. The procedure is performed to relieve pain, improve mobility, and restore function in patients with severe knee osteoarthritis, rheumatoid arthritis, or other conditions that cause significant joint damage.

The knee joint is made up of three bones⁚ the femur (thigh bone), the tibia (shin bone), and the patella (kneecap). During total knee replacement, the ends of the femur and tibia are resurfaced with metal implants, and a plastic spacer is inserted between the implants to create a smooth gliding surface. The patella may also be resurfaced with a plastic component.

Total knee replacement surgery is a major procedure, but it is generally considered safe and effective. With proper pre-operative preparation, post-operative care, and rehabilitation, most patients experience significant improvement in their pain and function following surgery.

The Procedure

Total knee replacement surgery is typically performed under general anesthesia, meaning the patient is asleep during the procedure. The surgeon makes an incision on the front of the knee and then carefully removes the damaged cartilage and bone from the ends of the femur and tibia.

Next, metal implants are inserted into the bone, and a plastic spacer is placed between the implants to create a smooth gliding surface. The patella may also be resurfaced with a plastic component. The incision is then closed with sutures or staples, and a dressing is applied to the wound.

Total knee replacement surgery typically takes 1-2 hours to complete. After surgery, the patient is taken to the recovery room, where they will be monitored closely for several hours. Once the patient is stable, they will be transferred to a hospital room or rehabilitation facility.

Total knee replacement surgery is a major procedure, but it is generally considered safe and effective. With proper pre-operative preparation, post-operative care, and rehabilitation, most patients experience significant improvement in their pain and function following surgery.

Benefits of Total Knee Replacement

Total knee replacement surgery offers numerous benefits for individuals suffering from severe knee pain and dysfunction due to osteoarthritis, rheumatoid arthritis, or other conditions. The primary goal of the procedure is to alleviate pain and improve mobility, enabling patients to regain a more active lifestyle.

One of the most significant benefits is pain relief. By replacing the damaged joint with a smooth, artificial surface, the surgery eliminates the pain caused by bone-on-bone grinding and inflammation. This pain relief can be profound, allowing patients to participate in activities they previously couldn’t even consider due to discomfort.

Another key benefit is improved mobility. The new joint provides a stable and pain-free range of motion, allowing patients to walk, climb stairs, and perform other activities more easily. This increased mobility can lead to greater independence and a higher quality of life.

Furthermore, total knee replacement can improve overall physical function and reduce reliance on medications for pain management. By restoring the knee’s functionality, the surgery can help patients regain their strength, flexibility, and stamina, enabling them to participate in recreational activities and enjoy a more fulfilling life.

Risks and Complications

While total knee replacement is a highly successful procedure, like any surgery, it carries potential risks and complications. It’s crucial to understand these risks and discuss them thoroughly with your surgeon before making a decision.

One common risk is infection. As with any surgical procedure, there’s a chance of infection developing in the joint. This can be serious and may require additional surgery and treatment.

Another potential complication is blood clots. Blood clots can form in the legs after surgery, and in rare cases, they can travel to the lungs, causing a pulmonary embolism. To prevent this, your surgeon will likely prescribe blood thinners and encourage you to get up and move around as soon as possible after surgery.

Stiffness and limited range of motion are also possible complications. This can occur if the joint doesn’t heal properly or if the muscles and tendons around the knee become tight. Physical therapy is essential for preventing stiffness and regaining full range of motion.

Finally, there’s a possibility of implant loosening or wear and tear over time. This can lead to pain, instability, and the need for revision surgery. While modern implants are designed to last for many years, they may eventually require replacement.
