Arthritis or traumatic injury to the hip can cause pain, deformity and stiffness that can severely limit daily activities. Hip replacement surgery can alleviate that pain and restore the normal alignment of the hip, allowing you to move easily.
Your hip is made up of two basic parts that move and work together to ensure smooth motion and function. When arthritis affects the joint and the cartilage that cushions the hip wears away or is destroyed, the hip joint requires replacement.
The materials used in your artificial joint are very strong and are designed to last a very long time inside your body. Your orthopedic surgeon will consider many factors, like age, bone density and the shape of your joints to determine the exact kind of hip replacement you’ll receive and how it will be inserted.

In the hip joint there is a layer of smooth cartilage on the ball of the upper end of the thighbone (femur) and another layer within your hip socket. This cartilage serves as a cushion and allows for smooth motion of the hip. Arthritis is a wearing away of this cartilage. Eventually it wears down to bone. Rubbing of bone against bone causes discomfort, swelling and stiffness.
Joint deterioration caused by osteoarthritis and other conditions such as rheumatoid arthritis, avascular necrosis, injury, and bone tumors may lead to breakdown of the hip joint and require the need for hip replacement surgery.
The goal of hip replacement is to relieve pain and improve function of the hip joint so that you can get back to enjoying the simplest activities like walking, driving and even standing.
During hip replacement, the surgeon removes the diseased bone tissue and cartilage from the hip joint. The healthy parts of the hip are left intact. Then the surgeon replaces and resurfaces the bones in the joint with new, artificial parts, recreating the smooth gliding surfaces that were once intact. This creates a smoothly functioning joint that does not hurt.
A total hip replacement is an operation that removes the arthritic ball of the upper thighbone (femur) as well as damaged cartilage from the hip socket. The ball is replaced with a metal ball that is fixed solidly inside the femur. The socket is replaced with a plastic or metal liner that is usually fixed inside a metal shell. This creates a smoothly functioning joint that does not hurt.
Results of Houston hip replacement will vary depending on the quality of the surrounding tissue, the severity of the arthritis at the time of surgery, the patient's activity level and the patient's adherence to the doctor's orders.
