Knee Creations, a VC-backed provider of knee treatments, has been acquired by Zimmer (NYSE: ZMH). The acquired company has developed a minimally-invasive procedure that helps the body heal defects in the bone, specifically in the knee. Its Subchondroplasty treatment targets chronic bone marrow lesions and fills them with an absorbable, biomimetic bone substitute material. Founded by Viscogliosi Brothers in 2007, Knee Creations took in an angel equity round and a Series A round of financing, the latter from Viscogliosi Brothers, Praefinium and Philadelphia Medical Investment Group.
