TKR is an acronym that stands for Total Knee Replacement. It refers to a surgical procedure performed to replace a damaged or deteriorated knee joint with an artificial one. This procedure is typically recommended for patients who suffer from severe osteoarthritis, rheumatoid arthritis, or knee injuries, which cause significant pain, stiffness, limited mobility, or joint deformity.
During a TKR, the diseased or damaged knee joint surfaces are removed, including damaged cartilage and bone. The replacements involve using prosthetic components made of metal, plastic, or ceramic, which closely mimic the natural knee joint. These components are fixed into position by securely attaching them to the thigh bone (femur) and shin bone (tibia). In some cases, the patella (kneecap) may also be replaced or resurfaced.
The primary goal of TKR is to reduce pain and restore functionality to the knee joint, improving the patient's quality of life. After the surgery, the artificial knee joint enables smoother movement, enhances joint stability, and facilitates weight-bearing activities, such as walking, running, or climbing stairs.
Like any surgical procedure, TKR involves certain risks, such as infection, blood clots, damage to surrounding blood vessels or nerves, or potential complications from anesthesia. Post-surgery rehabilitation, including physical therapy, is crucial for optimal recovery and to regain strength and flexibility in the knee joint.
TKR has become a common and successful orthopedic procedure, providing relief to numerous patients suffering from chronic knee pain and significantly improving their overall knee function.
