Total Knee Replacement (TKR), also known as Total Knee Arthroplasty, is a surgical procedure that involves replacing a knee damaged by arthritis or injury with artificial components. It aims to relieve pain and restore function in severely diseased knee joints, providing patients with a chance to return to normal activities with improved quality of life.
The Procedure
During a TKR, the surgeon removes damaged bone and cartilage from the surface of the knee joint – the end of the femur (thigh bone), the top of the tibia (shin bone), and the underside of the patella (kneecap). These parts are then replaced with artificial components made of metal alloys, high-grade plastics, and polymers. The prosthetic components mimic the knee’s natural movement and function, effectively replacing the damaged joint surfaces.
Benefits and Risks
TKR is highly successful in relieving knee pain and improving mobility, especially for patients suffering from osteoarthritis. The procedure has a high success rate, with most implants lasting 15-20 years or more. However, as with any major surgery, there are risks such as infections, blood clots, implant wear and tear, and the need for revision surgery in the future.
Recovery and Rehabilitation
Recovery from TKR involves several weeks of physical therapy to regain strength and mobility in the knee. While the immediate postoperative period may involve pain and discomfort, most patients can resume normal daily activities within 3-6 weeks post-surgery. Full recovery and maximum benefit from the surgery may take several months.
Total Knee Replacement represents a significant advancement in treating severe knee pain and disability due to arthritis or injury. It offers patients an effective solution to regain mobility and lead a more active, pain-free life.
