Intra-articular bone marrow concentrate injection protocol: short-term efficacy in osteoarthritis.

AIM Evaluate intra-articular injection of bone marrow concentrate (BMC), followed by platelet-rich plasma (PRP) injection at 8 weeks follow-up in moderate/severe osteoarthritis. DESIGN Single center, retrospective Case Series (n = 125). METHODS Bone marrow was aspirated/concentrated using a standardized technique. Patients received a single intra-articular injection of BMC, with follow-up injection of PRP at 8 weeks. RESULTS Median absolute pain reduction in all joints was five points (71.4%) on visual analog scale. Median patient satisfaction was 9.0/10, while 91.7% indicated that they would repeat the procedure and 94% said that they would recommend the procedure to a friend. CONCLUSION Intra-articular injection of BMC, followed by a PRP injection, can provide short-term benefits in moderate-to-severe osteoarthritis.
