All of these factors can cause pain and restricted range of motion in the joint. In addition, the bones become thicker around the edges of the joint and may form bony “spurs”. In a normal joint, articular cartilage allows for smooth movement within the joint, whereas in an arthritic knee the cartilage itself becomes thinner or completely absent. Osteoarthritis is the most common form of knee arthritis in which the joint cartilage gradually wears away. Tricompartmental knee replacement surgery is commonly indicated for severe osteoarthritis of the knee.

Lateral compartment – the area on the outside of the knee joint.

Medial compartment – the compartment on the inside of the knee.

Patellofemoral – the compartment behind the kneecap.

The knee can be divided into three compartments: Arthritis (inflammation of the joints), injury, or other diseases of the joint can damage this protective layer of cartilage, causing extreme pain and difficulty in performing daily activities.

The meniscus, the soft cartilage between the femur and tibia, serves as a cushion and helps absorb shock during motion. The knee is made up of the femur (thigh bone), the tibia (shin bone), and patella (kneecap).

Tricompartmental knee replacement, also called total knee arthroplasty, is a surgical procedure in which the worn out or damaged surfaces of the knee joint are removed and replaced with artificial parts.
