Knee Replacement Restores Mobility
Joint replacement surgery can give patients suffering from chronic knee pain a new lease on life. Whether the knee is failing due to sports injury or as a result of a degenerative disease like osteoarthritis, the knee joint can be replaced with a prosthesis made of plastic or metal.
Knee replacement options include:
According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases, more than a million joint replacement procedures occur every year, and more than 70 percent of those are knee replacements.
Typical candidates for knee replacement are age 60 to 75, but advancements in prosthetics have broadened the field of those benefitting from knee implants. There is no age restriction for this procedure. Experts say most artificial knee joints should last more than 15 to 20 years.

The knee replacement procedure relies on a coordinated effort by the patient, along with a team of orthopedic specialists, knee surgeons, case managers, and physical therapists.
Knee Arthroplasty Replaces Damaged Bone
Total knee replacement may also be called “resurfacing.” The surgeon uses minimally invasive arthroscopic knee surgery to remove damaged cartilage and some bone on the ends of the tibia and femur. These elements are then replaced with components that recreate the healthy surfaces of the knee joint. The implants may be cemented or inserted into the bone. The underside of the kneecap (patella) may then be cut and resurfaced with a plastic button. Plastic spacers are inserted between the metal parts to allow them to slide smoothly as the knee moves.
The selection of prosthesis for your knee replacement surgery depends on the individual condition of the knee and preferences of your orthopedic surgeon. Other options can include a knee implant with a rotating platform versus a fixed bearing design.
Partial knee replacement surgery, also called unicompartmental knee replacement, replaces only the parts of the knee joint that are worn down. This minimally invasive knee surgery may involve replacing either the kneecap femur joint or the femur shin joint (most common).
Revision total knee replacement takes place if a knee prosthesis fails for any reason, causing knee pain, swelling, instability or limited mobility. Most common reasons for implant failure are loosening from where it is attached to the bone, knee fracture, worn plastic spacer, osteolysis, or bone infection.
An orthopedic surgeon can remove existing implants (either all or part) and replace them with new. In some cases, damaged bone must be rebuilt with metal pieces or a bone graft. To treat bone infection, your orthopedic surgeon may recommend debridement to clear out bacteria. Another option is to remove the old implant, install a temporary spacer, administer antibiotic s for several weeks, then replace the implant once the infection clears.
