Although the knee appears to be a simple hinge-like joint, it is actually a complex joint. It is made up of several bones: femur (thigh bone), tibia (lower leg), and the patella (kneecap). These bones are all covered with cartilage to absorb the constant shocks created by movements. There are also two floating cartilages called menisci, the medial (inner) and the lateral (outer) rest on the tibial bone and also act as shock absorbers.

To keep your knee joint stabilized there are also ligaments inside and outside the joint. The medical and lateral collateral ligaments keep the knee stabilized from extreme side to side movements. The anterior and posterior cruciate ligaments keep the knee from buckling and giving way. The complete knee joint is also surrounded by a capsule that is filled with synovial fluid, which is a lubricating fluid to help our movements be smooth and pain free.

With such a complex system of bones, ligaments, and cartilage it is easy to see why knee injuries are so common. Injuries can range from a sprain or a strain, to fractures, to ligament or meniscal tears. In addition, the knee joint can also become diseased with osteoarthritis. Many knee injuries can be treated quite effectively with conservative care, such as bracing, anti-inflammatories, rest, physical therapy, and corticosteroid injections. Keeping your knees healthy through regular exercise and strengthening can decrease your chances of knee injury. If a knee becomes diseased with osteoarthritis and conservative care has failed, it may be suggested by your Provider to undergo a total knee replacement.

Myknee Replacements

The main cause of knee joint diseases is the wear of the cartilage, which is the smooth surface covering the bones in the knee. This is called osteoarthritis, and in the case of severe or advanced osteoarthritis, it may be suggested that you undergo a total knee replacement.

Dr. Matanky is pleased to offer the MyKnee total knee replacement by Medacta. MyKnee is a highly precise instrument because it is tailored for each patient starting from a radiological image of their own knee. This is a more accurate, faster, and less traumatic surgery for patients resulting in increased survival of the prosthesis, decreased blood loss during surgery, and a decreased risk of embolism. The technology used in MyKnee is very straightforward and potentially allows Dr. Matanky to reduce operating time, decreasing the time under anesthesia and risk of infection.
