Knee Joint Replacement
Knee Joint Replacement Overview
The procedure of knee joint replacement is called a total knee arthroplasty (TKA). This surgery involves replacing the existing knee joint with a manmade one. Orthopedic surgeons replace knee joints to end pain, stiffness, and loss of function.
Knee Joint Replacement Causes
Both chronic osteoarthritis and rheumatoid arthritis commonly cause people to lose knee function and damage the joint to the degree that they need a knee joint replacement (total knee arthroplasty or TKA). But knee damage may also stem from injury or infection. Generally, people require a TKA a decade earlier if the damage is due to rheumatoid arthritis as opposed to osteoarthritis.
