SAN FRANCISCO--(BUSINESS WIRE)--The Stone Research Foundation released findings of the longest and largest study of its kind on biologic knee joint repair. The study is published in July’s issue of The British Journal of Bone & Joint Surgery. Study findings indicate that arthritic patients can forestall, or in some cases, avoid, total knee replacement with artificial joints by opting for meniscal allograft transplantations performed concurrently with articular cartilage repair. The techniques replace worn meniscus with donated tissue and use the patient’s own stem cells for repair.
