After an initial period of rapid penetration in the first year, investigators of a level 1 study using radiostereometric analysis found a significantly lower steady state wear rate during 10-year follow-up among total hip arthroplasties performed with highly crosslinked polyethylene liners compared to conventional polyethylene.
In a recent presentation, one surgeon outlined his indications for follow-up and revision of metal-on-metal total hip replacements.
Thomas P. Schmalzried, MD, presented his experience at the International Congress for Joint Reconstruction San Diego 2012 meeting, which was held in collaboration with Orthopedics Today.
According to Schmalzried, revision should be considered in patients who display poor clinical results, such as pain or mechanical symptoms. Pseudotumor or other soft tissue involvement, such as edema and necrosis, are also a sign that revision should be performed within 3 months. Osteolysis and high metal ion levels should also bring revision into consideration.
Schmalzried stressed he still observes asymptomatic patients with “clean” MRIs, regardless of their metal ion levels.
A common, painful hip condition in elite athletes may be able to be repaired with an improved surgical technique, according to researchers presenting their work at the American Orthopaedic Society for Sports Medicine's Annual Meeting in Baltimore, Maryland.
"In our review of 21 male, elite athletes who had hip pain and instability issues (hypoplastic or labrum tear), 81 percent returned to play at a similar level as before they were hurt, after receiving an arthroscopic reconstruction technique using an ipsilateral iliotibial band autograft," said research author, Marc J. Philippon, MD, of the Steadman Philippon Research Institute in Vail, Colorado.
Dr. Tom Smith, Hip and Knee Specialist who is a board-certified Orthopedic Surgeon with Vanguard Medical Group, speak about the anatomy of the hip, joint pain, joint replacement, and some simple steps you can take.
Dr. Smith will also be sharing how he has been successfully performing Direct Anterior Approach Hip Replacement Surgery, a technique that few physicians are currently using due to the extensive training and specialized equipment. This surgery results in less pain, greater mobility and a quicker recovery time.

Knee osteoarthritis. It can start out as an occasional twinge that eventually becomes a constant pain, making it difficult to walk, stay active or just get through the day.
And when joint degeneration starts affecting your life, you may start thinking about surgery.
You're not alone. Knee replacements have become increasingly common among younger women, according to a January 2012 Finnish study published in Arthritis & Rheumatism.
Read on to learn what you need to know about knee replacements.
The reason women are more prone to knee injuries than men may go beyond differences in muscular and skeletal structure, according to researchers from Oregon State University.
“There are some muscular and skeletal differences between men and women, but that doesn’t explain differences in injury rates as much as you might think,” study author Samuel T. Johnson stated in an Oregon State University news release. “No one has really studied the role of the nervous system the way we have in explaining these differences, specifically the way sensory information is processed and integrated with motor function in the spinal cord.”
“We’re finding differences in nervous system processing,” Johnson stated. “The causes for those differences are unclear, but it may be due to either a biological difference, such as hormones, or a cultural difference such as different exercise and training patterns.”
Arthroscopy is an orthopedic procedure that is used to diagnose and treat joint or soft tissue problems by placing a small instrument, called an arthroscope, through a small incision into the joint. Once used exclusively as a preparation method for surgery, it is now an alternative to more invasive surgical procedures and is preferable in some cases due to a shorter recovery time.
Arthroscopic implantation of a polyurethane scaffold to treat partial meniscal lesions showed good results over other meniscal treatment methods at the 2-year follow-up, according to research presented at the European Society of Sports Traumatology Knee Surgery and Arthroscopy Congress 2012, here.
“This new scaffold is very interesting with preliminary results comparable to the CMI (Menaflex Collagen Meniscus Implant; Regen Biologics), but with an easier surgical management,” Muccioli said in his presentation.
Two studies presented at the 2012 annual meeting of the American Academy of Orthopaedic Surgeon highlight the dangers that smoking poses to patients receiving total knee or hip implants.
The researchers found that the overall revision rate – meaning the number of surgeries that had to be redone – was 10 times higher for smokers compared with nonsmokers: 10 percent vs. 1 percent. Smokers also had a significantly higher rate of complications compared with non-smokers (21 percent vs. 12 percent), including blood clots, abnormal heartbeat, irregular heartbeat, urinary tract infection and kidney failure.
Quitting’s not easy, but it’s worth it, says Dr. Lombardi. “The effect of nicotine may persist, but obviously it will [lessen] if you stop.”
