Knee replacement also referred to as knee arthroplasty or total knee replacement, is a surgical procedure to resurface a knee damaged by arthritis. Plastic and metal components are utilized to limit the ends of these bones which form the knee joint, together with the kneecap. This operation can be considered for somebody who has severe arthritis or even a serious knee injury.
Many kinds of arthritis may affect the knee joint. Osteoarthritis, a degenerative joint disease that affects middle-aged and elderly adults, can cause the breakdown of joint cartilage and adjacent bone in the knees.
Rheumatoid arthritis, which causes inflammation of the synovial membrane and results in excessive synovial fluid, which may result in stiffness and pain. Traumatic arthritis, arthritis due to injury, can lead to damage to the cartilage of the knee.
The objective of knee replacement surgery would be to segregate the areas of the knee joint which were damaged and to alleviate knee pain that can't be controlled by other treatments.
Anatomy of the kneeJoints is the areas where two or more bones meet. Most joints are mobile, allowing the bones to move. The knee is two long leg bones held together by muscles, ligaments, tendons, ligaments, and tendons.
Each bone end is covered with a layer of cartilage that absorbs shock and protects the knee. There are two groups of muscles involved in the knee, including the quadriceps muscles (located towards the front of the thighs), which straighten the legs, and the hamstring muscles (located on the rear of the thighs), which bend the leg at the knee.
Tendons are tough cords of connective tissues that connect muscles to bones. Ligaments are elastic bands of tissue that connect bone to bone. Some ligaments of the knee provide stability and protection of the joints, while other ligaments limit forward and backward motion of the tibia (shin bone).
The knee consists of the following:
This is the shin bone or larger bone of the lower leg.
