Hip joint replacement is surgery to replace all or part of the hip joint with an artificial joint. The artificial joint is called a prosthesis .
Hip arthroplasty; Total hip replacement; Hip hemiarthroplasty
The artificial hip joint has four parts:
A socket that replaces your old hip socket. The socket is usually made of metal.
The liner, which fits inside the socket. It is usually plastic, but some surgeons are now trying other materials, like ceramic and metal. The liner allows the hip to move smoothly.
A metal or ceramic ball that will replace the round head (top) of your thigh bone.
A metal stem that is attached to the shaft of the thigh bone to make the joint more stable.

X-rays often show changes in the hip joint associated with osteoarthritis (OA). But arthritis may not show up until more severe damage is done. Physical therapists are studying ways to test for mild OA that don't depend on X-rays. This study is a report on one patient who was diagnosed with OA of the hip based on hip pain and range of motion. A 43-year-old woman was treated for right hip pain off and on for five years before seeing a physical therapist (PT). The PT gave her a special set of questions to measure pain, stiffness, and function. Follow-up tests included range of motion, strength, and leg length. Her pattern of walking was also reviewed. The patient had decreased right hip flexion and right hip inward rotation. Trunk and knee motion were normal. Testing showed decreased strength in three groups of hip muscles on the right side. A special test for hip arthritis called Patrick's test was positive on the right. Studies show that decreased hip internal motion and reduced hip flex...

But now months after the surgery, you are disappointed with your reality of living with ongoing pain or even worse pain than you had before. What went wrong? Why aren’t you experiencing the pain-free life that you dreamed of? A few things can be going wrong and preventing you from the best possible results after the replacement of your hip.
First and foremost, you might be caught in a painful triad of arthritis involving both the hips and the spine. Replacing one or both hips does not solve the back pain. And fusing the back does not solve the hip pain. The hip-spine connection is frequently encountered in the elderly because all of these parts have deteriorated over time. 1 Sometimes hip arthritis is misdiagnosed as low back pain. Sometimes low back pain is misdiagnosed as hip arthritis. And many times both are seen together in the same person. Even someone who has had t...
