Study Design

Intervention model single group assignment
Masking open label
Primary purpose treatment
microdrilling surgery

injections of bmac + prp + ha
All patients will receive up to 12 post-operative intra-articular knee injections of BMAC (derived from iliac crest), PRP (derived from peripheral blood) and HA (Supartz)
