Clinical trial shows implantable shock absorber Knee pain is commonly caused by osteoarthritis, a chronic condition that affects approximately 14 million Americans of all ages.
Results from a multi-center clinical trial, presented today at an orthopedic symposium in Boston, show a new implantable shock absorber can relieve pain and improve function. Dr. David Flanigan, an orthopedic surgeon at The Ohio State University Wexner Medical Center, enrolled patients in the trial at the medical center and was first in the U.S. to implant the MISHA Knee System made by Moximed.?There really hasn?t been much to offer for knee arthritis between the more basic options like medications, therapy and injections all the way to joint replacement,? said Flanigan, who is also a professor of orthopedics at the Ohio State College of Medicine ?This shock absorber could be an in between step patients need.?The device involves a piston that anchors to the inner side of the femur and tibia bones with a small plate. Trial data showed significant reduction in pain scores and improvement in function scores for more than 90% of the 81 trial participants. The shock absorber had a success rate of 86% compared to the most common procedure, high tibial osteotomy, which has a success rate of 66% and is typically used to treat symptomatic osteoarthritis of the medial compartment of the knee.?When you're walking, doing activities, it's going to take away about 30% of that shock or stress on the knee every time you put weight on your leg,? said Flanigan. ?You see patients who are struggling just to walk and have pain on a daily basis.
