Safety and Feasibility of Umbilical Cord Wharton's Jelly Allograft Injections for Knee Osteoarthritis

This is a Pilot Study which is randomized, prospective, open label, dose escalation, non-controlled study in which the safety and feasibility of intra-articular Wharton's Jelly (WJ) allograft will be evaluated in patients suffering with knee OA. The participants will be randomized to one of three dosing treatment arms that will consist of one intra-articular knee injection containing either low dose, medium dose or high dose WJ allograft tissue.

As this is a Pilot Study primarily designed to evaluate safety, no control will be used. The dosing groups will consist of either 2cc WJ Allograft (Low Dose), 3cc WJ Allograft (Medium Dose), or 4cc WJ Allograft (High Dose) with 120 total patients randomized into the three arms equally. In addition to baseline outcome instruments along with imaging and laboratory studies, patients will be followed for one year for evaluation of safety, pain relief and functional improvements.
