Knee arthroplasty, also known as knee replacement surgery, is a surgical procedure used to replace a damaged or diseased knee joint with an artificial implant.
The procedure involves removing the damaged or diseased parts of the knee joint and replacing them with a metal or plastic implant. The implant consists of a metal femoral component, a plastic tibial component, and a plastic patellar component.
Knee arthroplasty may be recommended for individuals with severe knee pain and disability due to conditions such as osteoarthritis, rheumatoid arthritis, or injury to the knee joint.
The goal of knee arthroplasty is to relieve pain, improve mobility and function, and increase the quality of life for individuals with knee joint damage or disease.
Recovery after knee arthroplasty can take several weeks to several months, and typically involves physical therapy and rehabilitation to regain strength and mobility in the knee joint. Postoperative management is important to prevent complications, such as blood clots, infections, and joint dislocation.
