American Orthopaedic Society for Sports Medicine, July 12-15, 2012

The American Orthopaedic Society for Sports Medicine Annual Meeting

The annual meeting of the American Orthopaedic Society for Sports Medicine, AOSSM 2012, was held from June 12 to 15 in Baltimore and attracted approximately 1,700 participants from around the world, including sports medicine specialists, athletic trainers, physical therapists, and family physicians. The conference featured the latest advances in sports medicine, with presentations focusing on the identification, prevention, treatment, and rehabilitation of sports injuries.

In one study, Elizaveta Kon, M.D., of the Rizzoli Orthopaedic Institute in Bologna, Italy, and colleagues found that the use of platelet rich plasma (PRP) was safe and effective for the treatment of cartilage tears.

"The key result of our randomized controlled study is that PRP is better than hyaluronic acid for the treatment of knee degeneration only in case of low-grade osteoarthritis. In case of severe osteoarthritis, results are comparable," Kon said. "This study will permit us to establish better indications for use of PRP for the treatment of osteoarthritis and also to create a scientific basis for the reimbursement policy. Data are still preliminary and we are looking forward to have more consistent scientific evidence once the trial is concluded."

In another study, Marc J. Philippon, M.D., of the Steadman Philippon Research Institute in Vail, Colo., and colleagues found that a new hip reconstruction technique was effective for patients with hip pain and instability issues.

The investigators evaluated 21 male athletes with hip pain and instability issues and found that a new arthroscopic reconstruction technique using an ipsilateral iliotibial band autograft resulted in 81 percent of athletes returning to play at a level similar to their pre-injury level.

"The results of the study are promising. We found that this new treatment is effective in a select group of patients who previously had no other treatment options," Philippon said. "This new approach is going to be made available to sports medicine surgeons and is likely to improve outcomes in these patients."

David Lintner, M.D., of the Methodist Center for Sports Medicine in Houston, and colleagues found that surgical repair of superior labral (SLAP) shoulder injury was not always effective and did not allow all athletes to return to play at the level seen prior to injury.

"Shoulder pain in professional throwers with documented SLAP tears should be treated non-surgically through at least two cycles of physical therapy before considering surgery. Results of surgery as measured by return to actual on-field performance statistics are much less positive than prior definitions of 'return to play,'" Lintner said. "This study confirms that surgery should be performed for SLAP lesions in professional throwers only when the athlete cannot compete, despite extended physical therapy and documented improvement in glenohumeral internal rotation deficit and scapular dyskinesia. SLAP repairs are becoming very common but should be avoided in this population."

Diane Dahm, M.D., of the Mayo Clinic in Rochester, Minn., and colleagues evaluated functional outcomes in patients who had undergone at least two anterior cruciate ligament (ACL) reconstructions. The investigators evaluated a total of 15 patients and found that a high percentage had meniscus and cartilage damage associated with their recurrent ACL injury.

"Although patients improved clinically by virtue of outcome scores and objective stability, most did not get back to their prior activity levels," Dahm said. "Overall, we found that only 27 percent got back to their prior activity levels, based on Tegner scoring. The reason that this may have occurred is that, although patients reported having a stable knee following repeat revision surgery, they may have been apprehensive in their return to high activity levels as a result of going through multiple ACL reconstructions."

The investigators also found that patients with higher-grade chondral lesions (grade 3 or 4) and/or a body mass index greater than 28 kg/m² had worse functional outcomes.
