A total knee replacement (also called total knee arthroplasty) might be more accurately termed a knee "resurfacing" because only the surfaces of the bones are replaced. There are four basic steps to a knee replacement procedure:
Knee replacement surgery replaces parts of injured or worn-out knee joints. The surgery can help ease pain and make the knee work better. During the surgery, damaged bone and cartilage are replaced with parts made of metal and plastic.
All knee replacement components that we used incorporate these modern design features. Other variations in total knee implants include a ceramic “oxinium” surface, the “rotating-platform” knee, and other brands marketed by implant companies.
A total knee replacement (TKR) is a complex procedure that requires an orthopedic surgeon to make precise measurements and skillfully remove the diseased portions of your bone, in order to...
Implants are made of metal alloys, ceramic material, and strong plastic parts. Up to three bone surfaces may be replaced in a total knee replacement: The lower end of the femur. The metal femoral component curves around the end of the femur (thighbone).
In most cases, a total knee replacement reduces pain and improves mobility. However, surgery can be costly, it can take several weeks or months to recover, and there is a small risk of...
This type of surgery typically requires special tools so that the surgery team can see and do the procedure through the smaller incision. The knee has several parts: the lower end of the thigh bone (femur), the upper end of the shin bone (tibia), and the kneecap (patella).
Traditional total knee replacement involves a 7-8” incision over the knee, a hospital stay of 3-5 days, and a recovery period (during which the patient walks with a walker or cane) typically lasting from one to three months.
See Total Knee Replacement Surgical Procedure. Most artificial bone components are attached using cement, but cementless options are available. This page discusses the materials used to make knee components; gender-specific knee components; and custom knee replacement components.
A knee replacement is surgery to replace all or some of your knee joint. It’s a type of procedure called an arthroplasty (joint replacement). A surgeon will remove damaged parts of your natural knee joint and replace them with an artificial joint (a prosthesis) made of metal and plastic.
