The Steadman Philippon Research Institute 2007 Annual Report
Patients with hip pain may suffer from femoro- acetabular impingement, or FAI, in which bony abnormalities of both the femur and acetabulum irregularly and repetitively contact each other, creating damage to articular cartilage and labrum. This may lead to a more rapid onset of osteoar- thritis, which is the leading cause of disability in the United States. In the past, the treatment for FAI was an open surgical dislocation procedure to repair this pathology. It has shown good mid-term results, but it is a highly invasive procedure.
The recovery from this open surgical dislocation procedure may limit activities for nine months. This length of postoperative inactivity is not feasible for the recreational or professional athlete. Dr. Marc J. Philippon has developed an arthroscopic technique to repair this hip joint disease that allows individu- als to return to activities, including athletics, as early as three months.
Patients with osteoarthritis of the shoulder have pain and loss of function that significantly affect their quality of life. When the disease becomes more advanced and the symptoms do not respond to conservative methods, total shoulder arthroplasty (TSA) is the preferred surgical treatment. The number of TSAs performed annually in the U.S. has increased from about 5,000 in the early 1990s to more than 20,000 in 2005. This is largely because an aging population wants to stay active, but
it may also be due to better prosthesis designs, better surgical techniques, and better training of surgeons.
While the overall outcomes after shoulder replacements are excellent, the motions of the bones or implants inside the shoulder joint during motion in living subjects are not well known because we haven’t been able to “see” inside the joint.
