    Hello, I am new to this group. I am a 54 year old male with osteoarthiris in both hips, a former quarter miler at Bucknell University who can barely walk now. I have been very impressed by conversations I have had with Dr. James Pritchett in Seattle.

  • Running after Hip Resurfacing

    I advise patients not to return to impact sport for 1 year after surgery. For those patients who want to road run, I get them running on a treadmill at 10 months post-op and they resume road running at 12 months post-op. My unit published on activity level after resurfacing some years ago in a group of patients who followed those rules. In young men with a single osteoarthritic hip resurfaced, 92 % played sport and 62 % played impact sport. The ladies were not quite as active, but you can see from the publication that they still had an impressive activity level. In the total group their 10 year implant survival is 99.8 % showing that high activity introduced at a sensible time does not deteriorate the results.

  • NCP-Neck Capsule Preservation-Approach in Hip Resurfacing, What is it?

    The NCP approach, at least the way that we mean it, is a different way to incise the capsule in order to gain access to the hip joint. Usually with THR, the capsule is detached from the femoral neck and flipped back. It is usually preserved and repaired in order to avoid dislocation.

  • Cementless, Should you have it by Dr. Gross & Comments

    I agree with every word that Dr. Gross has said apart from the fact that his 'guess' that cement will be the cause of failure in resurfacings after 10 yrs. This particular statement is only a guess and may prove not to be true.

  • Bone Health & Hip Resurfacing by Thomas P. Gross, M.D.

    Bones support and shape our bodies by anchoring muscles, protecting our vital organs, and they are very much alive. Bones constantly revitalize themselves through a process called bone remodeling. During this process cells called osteoclasts break down the old bone so the body can reabsorb it in order for other cells (osteoblasts) to form new bone.

  • Cementless by Dr.Thomas Gross

    I recommend uncemented fixation of both the femoral and acetabular components of metal-on-metal hip resurfacing devices. Currently, the market standard used by most surgeons around the world is uncemented fixation of the acetabular component and cement fixation of the femoral component. I was one of the first surgeons in America to begin performing metal-on-metal hip resurfacing in 1999.
