Numerous types of arthritis might affect the knee joint. Osteoarthritis is a degenerative joint disease which affects mainly the older adults and middle aged people in general. There is a breakdown of adjacent joint cartilage and bone in the knees in case of osteoarthritis patients. Rheumatoid arthritis causes inflammation of the synovial membrane resulting in the accumulation of synovial fluid thus leading to stiffness and pain. Another arthritis resulting from the damage to the cartilage of the knee due to an injury is known as traumatic arthritis. The focus of doing knee replacement surgery is to replace the parts of the knee joint that suffer irreparable damage to relive the pain and make the life better for the patient.
