Designed to relieve pain and restore function in severely damaged knee joints, total knee replacement (TKR), sometimes referred to as knee arthroplasty, is a quite successful surgical operation. Most often advised for those with advanced osteoarthritis, rheumatoid arthritis, or traumatic injury, TKR entails artificial metal and plastic components replacing the damaged cartilage and bone in the knee.
The operation typically lasts one to two hours under either general or regional anaesthesia. Modern TKR methods provide better precision, faster recovery, and less post-operative pain; among these are minimally invasive surgery and computer-assisted navigation. Usually starting physical therapy 24 hours following surgery, patients want to restore strength, mobility, and flexibility.
Good quality of life can be greatly enhanced by successful knee replacements, enabling people to resume daily activities free from or with minimal discomfort. Although the artificial joint might not provide the same range of motion as a natural knee, most patients find significant improvement in joint performance. Typically, depending on activity level and general health, the implants last 15 to 20 years or more.
When conservative therapies like medicine and physiotherapy no longer provide relief for persistent knee pain, total knee replacement is a safe and tried-for answer.
