Knee Implants/Knee Replacement (Knee Arthroplasty)

The ability to walk easily depends upon the intricate working of the knee joint, the largest joint in the body. The knee is formed by the junction of three bones: the femur (the thigh bone), the tibia (the shin bone), and the patella (the kneecap). These bones are connected to each other by strong ligaments.

A healthy knee lets you move your lower leg forward and backward, and swivel slightly to point your toes. Ligaments and cartilage stabilize and support the join, preventing your knee from moving too far from side to side.

Most knee replacements attempt to mimic the normal motion of the knee though something as common as walking is easy for most, but for those with advanced arthritis, such repetitive motion on an already weakened joint can be quite painful. Often, knee replacement, or a partial knee replacement, is the only option to alleviate the pain.

The right implant that will be used for your knee replacement surgery will depend on many factors that your surgeon will take into account before scheduling your surgery. These factors are based on your age, weight, activity level and health.

The longevity and performance of any joint, whether it is your original joint or a replacement one, depends on a person’s activity level, weight and general health. Just as wear in the natural joint contributed to the need for a replacement, wear in the implant may eventually require a second surgery known as a revision.

Partial Knee Replacement

Partial knee replacement is a surgery that may be considered as a treatment option for severe arthritis of the knee. Traditionally, patients have undergone a full knee replacement but this partial procedure uses a smaller incision and has a faster recovery period because only the most damaged areas of cartilage are removed from the joint, leaving the healthy parts of the joint in place for continued use.

Revision Surgery

The longevity and performance of any joint, whether it is an original joint or a replacement one, depends on a person’s activity level, weight and general health. Just as wear in the natural joint contributed to the need for a replacement, wear in the implant may eventually require a second surgery known as a revision.
