Anatomy of a Knee
The knee joint is comprised of three parts: the lower end of the femur (thigh bone), the upper end of the tibia (shin bone), and the patella (knee cap). Knee replacement involves removing the worn surfaces of bone and cartilage on both sides of the joint, as well as the backside of the kneecap when it is necessary. The bone is then replaced with metal implants, and the cartilage is replaced with a special plastic.
There are many different types of implants available, and many different techniques used to place the implants. Your surgeon will evaluate your unique situation and recommend the options that are best for you. Your own soft tissues (muscles, ligaments and tendons) will support the new joint. They will be temporarily weakened as a result of the surgery. Your physical therapist will teach you a series of exercises designed to help restore strength and balance to your muscles and ligaments. These exercises are vital to the success of your surgery.
Precautions Following Knee Surgery
After knee replacement surgery, the following activities may be restricted:
- Kneeling
- Deep knee bends/squatting
- Pivoting/twisting
Please clarify with your surgeon what activities are acceptable for your knee before attempting them.
