To reduce joint pain, total hip replacement surgery is recommended for patients. During this surgical procedure, the painful hip is replaced with a prosthetic artificial joint. The procedure for a total hip replacement involves the removal of the arthritic ball of the upper thighbone (femur) as well as damaged cartilage from the hip socket. The damaged ball is replaced with a metal ball that is fixed inside the femur. The socket is replaced with a plastic liner that is fixed inside a metal shell. This creates a smoothly functioning ball-and-socket joint that does not hurt.
It is estimated that 90-95% of patients who have this procedure achieve good to excellent results with relief of pain and discomfort, and most importantly an increase in mobility and physical activity. Total hip replacement procedures allow patients to recover quickly and many are able to walk the first day following the surgical procedure.
The total knee replacement procedure removes the knee joint and replaces it with a new, prosthetic artificial joint. The knee joint is much a like a hinge, it is formed where the thighbone (femur) and the shinbone (tibia) meet. The interior lining of the knee is a delicate cushion of cartilage. Over time, that soft and delicate cartilage cushion can wear away. As it does, the knee becomes painful and rigid to move.
Three things are accomplished with a total knee replacement: the worn-out cartilage is replaced with artificial cushioning, the end of the femur is replaced with a smooth metal surface, and the tip of the tibia is replaced with a piece of plastic and stem made of metal. In some procedures, a plastic piece may be added to the rear of the kneecap, which creates a surface that is smooth.
It is estimated that 90-95% of patients achieve good to excellent results with relief of pain and discomfort, and most importantly an increase in mobility and physical activity. Total knee replacement procedures allow patients recover quickly and many are able walk the first day following their surgery.
