VITAMIN E-ENHANCED POLYETHYLENE LINERS SHOW LOW WEAR IN THA PERFORMED FOR OA

The amount of head penetration and cup migration was low in patients with osteoarthritis who underwent total hip arthroplasty with vitamin E-enhanced highly crosslinked polyethylene liners regardless of the femoral head material used in the implant or the size of the femoral head. "We have demonstrated less wear compared to any other study of polyethylene," Henrik Malchau, MD, PhD, of Massachusetts General Hospital (MGH), in Boston, one of the investigators, told Orthopaedics Today Europe. "We have not demonstrated any side effects in implant stability."
