STAR ANKLE JOINT REPLACEMENTS LAST LONG TERM AND PROVIDE RELIEF FOR PATIENTS
NEW YORK, NY -- May 2, 2011 – A report on the STAR™ Ankle prosthesis published in the journal, Foot & Ankle International (May 2011 edition, Volume 32 #5 © American Orthopaedic Foot & Ankle Society) is the first long term U.S. prospective study of the three-part STAR total ankle joint replacement following the Pre Market Approval (PMA) by the FDA (U.S. Food and Drug Administration) in May 2009. Foot and ankle surgeons, Jeffrey A. Mann MD, Roger A. Mann MD and Eric Horton MD of Oakland, CA reported that 91 percent of prostheses remain implanted at an average follow-up of 9.1 years. Further, 92 percent of the patients were satisfied with their outcome.
The long term study was conducted on 84 STAR total ankle replacements, performed in 80 patients. Postoperatively, patients were evaluated with the AOFAS® (American Orthopaedic Foot & Ankle Society) score for pain and function, and serial radiographs were evaluated for stability and alignment of the prosthesis. Implant failure, secondary procedures, and complications were recorded. The report notes a statistically significant decrease in pain and improvement of functional outcomes.
The report concluded that "the first U.S. prospective long-term survivorship data with the STAR Ankle prosthesis found it to be an excellent long-term option for the treatment of ankle arthritis."
David B. Thordarson MD, Editor-in-Chief of Foot & Ankle International, commented: "These results help confirm longer term observations of total ankle replacement patients in Europe and will lead to greater acceptance and progress of the procedure in the U.S."
