If the pain and stiffness of the hip joint are severe and other treatments have not brought sufficient relief, a hip replacement may be recommended. The doctors at Hartzband Center for Hip & Knee Replacement in Paramus, NJ will conduct a thorough examination that includes x-rays, strength and range-of-motion tests, a medical history and a series of questions, to determine whether a total hip replacement is right for you.
Nevertheless, as a cause leading to revision hip replacement, infection is the third most common. In several studies which assess the causes of primary hip replacement failure, infection of the joint is the most challenging and potentially devastating cause with 15% of all revision hip replacement procedures being done for this reason . If an artificial joint becomes infected, the pain is typically more constant than with a loose, but non-infected joint, but symptoms greatly vary with the type of infecting organism. Along with pain, symptoms include a stiffening of the joint, making movement quite difficult. On rare occasion, a prosthetic joint infection can make the patient systemically ill with fever, chills, weight loss, and lethargy.

Hip resurfacing arthroplasty is a type of hip replacement ideally suited to active people who need a total hip replacement at a younger age. The purpose of a hip replacement is to remove the damaged portions of the hip joint including the femoral head (ball) and acetabulum (socket) and replace them with a smooth, artificial joint that will make the hip strong, stable, and flexible again. Younger and more active patients run the risk of wearing out a traditional hip replacement and may need a second hip replacement during their lifetime. Such revision surgery can be difficult and last a shorter lifetime than the original hip replacement. Hip resurfacing is a bone conserving procedure where, instead of removing the head and a portion of the neck of the femur, the head of the femur is carefully reshaped and then covered with an anatomically designed metal sphere that acts as the new femoral head. As with a traditional total hip replacement, the hip socket is replaced as well. Because the new head and socket are made entirely of metal, there is less chance that these pieces will wear out. In addition, the artificial femoral head is much larger than the femoral head used in a traditional hip replacement and allows a greater range of motion with little risk of dislocation. Patients who have had hip resurfacing arthroplasties have been able to return to demanding physical activity and sports including bike riding, marathons, and triathlons. Not all patients are candidates for hip resurfacing. After a thorough history, physical examination, and x-rays, you and your surgeon will discuss whether or not hip resurfacing is right for you.
