What Is Osteoarthritis?
9. Surgery
Arthroscopy is a procedure that is minimally invasive and can be used to remove loose bodies and meniscal tears. Osteotomy is a procedure for patients with a misaligned knee or hip who intend to continue with some physical activity.
Arthroplasty is a procedure where there is removal of the joint surface and a metal or plastic prosthesis is inserted. This prosthesis is then held in place by bone ingrowth or cement. Ten to 15 years of viability can be expected from the prosthesis provided that there are no complications. One of the main concerns of arthroplasty is infection. However, this is now quite rare due to the use of perioperative antibiotics. Fusion can also be performed to relieve pain. This is a procedure where there is union of the bones on either side of the joint. However, it prevents motion and causes more stress for the surrounding joints.
