Stem cell knee injection shown to regenerate meniscus, reduce pain

 Results of a randomized, double-blind controlled study in the Journal of Bone and Joint Surgery supported the use of human mesenchymal stem cell for meniscal regeneration and the control of knee pain. 
“There was evidence of meniscus regeneration and improvement in knee pain following treatment with allogeneic human mesenchymal stem cells,” C. Thomas Vangsness Jr., MD, and colleagues wrote in the study. “These results support the study of human mesenchymal stem cells for the apparent knee-tissue regeneration and protective effects.”
The study followed 55 patients at seven institutions who underwent partial medial meniscectomy and received the study treatment 7 days to 10 days after meniscectomy via a superolateral knee injection.
