60 patients undergoing a partial meniscectomy were randomized to receive a single postoperative injection of allogeneic human mesenchymal stem cells (50x10^6 or 150x10^6 cell count) or a control vehicle injection of sodium hyaluronate, 7-10 days after surgery. The purpose of this study was to determine if a single intra-articular injection of mesenchymal stem cells caused meniscal regeneration over 2 years, as well as to investigate the safety of such treatment. More patients treated with the stem cell injection were observed to have an increase in meniscus volume of >15%, and patients with osteorthritis appeared to have an added benefit of reduced pain. No significant immunological responses were observed.
