Patients who lost knee motion after reconstructive ACL (knee) surgery were more likely to develop osteoarthritis, pain, stiffness in joints, reveals study conducted by researchers.
"Our research shows that patients given rehabilitation that emphasizes full motion be obtained and maintained throughout time after surgery have more favourable results on x-rays than patients who lose motion," said lead researcher K. Donald Shelbourne, MD, Founder, Shelbourne Knee Center.
AdvertisementThe study examined data from 780 patients who were at least five years after ACL reconstruction with a patellar tendon graft.
In individual follow-ups, patients were evaluated and rated based on knee range of motion tests and radiographs.
The percentage of patients with normal radiographs (no arthritic changes in the knee) was 71 percent in patients with normal range of motion compared to 55 percent of patients who showed deficits in motion.
In patients who had similar meniscus removal, osteoarthritis was observed more in patients who had motion deficits.
"Something like osteoarthritis can be debilitating and our goal is to continually find new ways to help patients avoid such a problem," Shelbourne stated.
The study was presented at the American Orthopaedic Society for Sports Medicine's Annual Meeting in San Diego, California, July 7-10, 2011.
