What we need to know about knee replacements

Knee replacement surgery, also known as knee arthroplasty, is a highly effective procedure designed to relieve pain and restore function in severely damaged knees. This surgical intervention is often recommended for patients suffering from advanced osteoarthritis, rheumatoid arthritis, or severe knee injuries that result in chronic pain and limited mobility. The procedure involves replacing the damaged parts of the knee joint with artificial implants made of metal, plastic, or ceramic components.

The decision to undergo knee replacement surgery is typically based on the severity of symptoms and the patient’s response to non-surgical treatments, such as medications, physical therapy, and lifestyle modifications. When these measures fail to provide relief, knee replacement may be the best option for improving quality of life.

There are two main types of procedures: total knee replacement (TKR), which involves replacing the entire joint, and partial knee replacement (PKR), which targets only the affected portion of the joint.

Modern advances in surgical techniques and implant materials have significantly improved the outcomes of knee replacement surgery. These advanced techniques have enhanced function, reduced recovery time, and help minimise post-operative complications. Most patients experience a dramatic reduction in pain and a significant improvement in joint function after surgery. However, the success of the procedure also depends on post-operative rehabilitation, including physical therapy, to restore strength, mobility, and range of motion.

While knee replacement is generally safe, potential risks include infection, blood clots, implant loosening, and stiffness. Patients are advised to discuss these risks and benefits thoroughly with their healthcare provider before proceeding. With proper care, knee implants can last 15-20 years or more, allowing patients to resume many of their daily activities pain-free. For those suffering from debilitating knee pain, knee replacement surgery offers a transformative solution, enabling them to regain their independence and improve their overall quality of life.
