What is a knee replacement surgery?

A knee replacement (also known as knee arthroplasty, total knee replacement) is a procedure that resurfaces a damaged knee. The kneecap and ends of the bones that make up the knee joint are covered with metal or plastic. For those with severe arthritis or severe knee injuries, this surgery might be an option.

The knee joint can be affected by a variety of types of arthritis. Osteoarthritis is a degenerative joint condition that mostly affects middle-aged and elderly people. It can cause joint cartilage to break down and bone loss in the knees. Rheumatoid, or inflammation of the synovial membrane, can cause stiffness and pain. Traumatic arthritis, or arthritis caused by injury, can cause damage to the knee cartilage.

Knee replacement surgery’s goal is to repair or replace damaged parts of the knee joint and relieve any pain in the knee that cannot be controlled with other methods.

Anatomy of a knee

The joint is the area where two or more bones meet. The majority of joints can move, so they allow bones to move. The knee is basically 2 long legs bones that are held together by muscles and ligaments. A layer of cartilage covers each bone to absorb shock and protect the knee.

Two groups of muscles are involved in the knee: the quadriceps muscles, located on the front of your thighs, which straighten your legs; and the hamstring muscle, which bends the leg at the knee.

Tendons connect bones and muscles by connecting them with tough connective tissue cords. Ligaments are elastic tissue bands that connect bone and bone. While some ligaments in the knee offer stability and protection to the joints, others limit forward and backward movement for the tibia (shinbone).

The reasons for the procedure

Knee replacement surgery can be used to treat pain or disability in the knee. Osteoarthritis is the most common reason for knee replacement surgery.

Osteoarthritis can be described as the destruction of joint cartilage. The cartilage and bones can be damaged and cause pain. Because of severe degenerative joint disease, people may have difficulty performing normal activities such as climbing stairs or walking that require bending at their knees. Because the joint isn’t stable, it may cause swelling or “give-way” in the knee.
