The hip is one of the body's largest joints. The hip joint is like a ball and socket joint. The ball is formed by the top of the thigh bone (femur) and the socket is formed by some part of the pelvis. Usually, the surfaces of the bones are covered with a smooth cushion-like coating (cartilage). A thin tissue called the synovial membrane surrounds the hip joint. In a healthy hip, this membrane makes a small amount of fluid that lubricates the cartilage and eliminates almost all friction during hip movement and the bands of tissue called ligaments (the hip capsule) connect the ball to the socket and provide stability to the joint. Over time, the cartilage can wear away, causing pain, stiffness, and discomfort in moving. The solution is Hip Replacement or Hip Arthroplasty, which is a surgical procedure where the worn-out surfaces of the hip are replaced with a prosthesis. Hip replacement can relieve or eliminate pain, improve mobility, and help you regain your joyful life
Total hip replacement is done for arthritic hip where socket as well as femoral head is damaged, hence both parts of the joint are replaced.
In this only femoral head part is replaced. This is usually done in elderly patients with fractures.
The artificial joint has its life and on average it is 20 to 25 years. If you look after with all precautions it may last longer. Due to wear and tear of the artificial joint either one or both parts of the joint which have been replaced previously may need to be changed.
The eligible candidates for this surgery suffer from moderate to extreme arthritis pain in the hip. The patients who are unable to do daily living activities are the candidates for surgery.
Most common condition responsible for arthritic hip is osteonecrosis, commonly called as AVN which means the part of the ball bone dies due to poor blood supply. The other conditions are rheumatoid arthritis, failed fractures, fresh fractures (elderly patients) and degenerative arthritic hips
The total hip joint replacement complication rate is very low. Below are some of the conditions that can limit or prolong full recovery.
We are committed to deliver solutions and transforming the way joint replacement procedures are performed.
