Knee injuries in women linked to motion, nervous system differences

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.”

What is arthroscopy?

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.

Polyurethane scaffold promotes meniscal regeneration, shows good 2-year results

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.

Indications and techniques for hip arthroscopy continue to evolve

"Hip arthroscopy is an evolving science," Charles A. Bush-Joseph, MD, of Midwest Orthopaedics at Rush in Chicago, told Orthopedics Today. "We are clearly better able to more accurately diagnose hip and groin conditions. Industry is catching up. There has been dramatic innovation in the equipment surgeons use to perform these types of procedures, making them more reliable and reproducible."

High impact sports reduce durability of hip implants

French researchers have confirmed that high-impact sport, such as jogging or soccer, increases the risk of total hip arthroplasty mechanical failure, according to a study published in Clinical Orthopaedics and Related Research.

“Since participation in sport is now a reality for a significant number of total hip arthroplasty (THA) patients, surgeons may need to adapt their choices of bearing surfaces in implants to accommodate this growing trend,” the authors wrote.

Patient-specific planning, navigation system improves the THA experience

Total hip arthroplasty routinely provides patients with greatly improved quality of life, however the process of performing THA requires that many anatomical issues must be addressed that are not predicted on preoperative radiographs.
