Total Knee Replacement (TKR), also known as Knee Arthroplasty, is a surgical procedure that involves replacing a knee joint damaged by arthritis or injury with an artificial joint. This surgery is considered when conservative treatments, such as medications, physical therapy, and lifestyle changes, fail to relieve severe pain and mobility issues.
Indications
TKR is primarily recommended for patients suffering from severe knee pain and functional limitations due to conditions like osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis. The goal is to alleviate pain, correct leg deformity, and restore knee function.
Procedure
During a TKR, the damaged surfaces of the knee joint, including the ends of the femur (thigh bone) and tibia (shin bone), and often the underside of the patella (kneecap), are removed and replaced with artificial components. These components are typically made from metal alloys and high-grade plastics, designed to mimic the knee’s natural movement.
Recovery and Rehabilitation
Postoperative care involves pain management, prevention of complications like blood clots, and starting physical therapy early to promote knee strength and mobility. Rehabilitation is crucial for a successful outcome, with exercises gradually increasing in intensity to improve joint function.
Outcomes
TKR has a high success rate, with most patients experiencing significant pain relief, improved mobility, and an enhanced quality of life. While artificial knee joints can wear out over time, modern prostheses can last 15-20 years or more, depending on factors like the patient’s activity level and weight.
Total Knee Replacement is a highly effective solution for individuals with debilitating knee conditions, offering a pathway to regain mobility and lead a more active life.
