Background: Bone marrow aspiration (BMA) is among a group of autologous cell-based therapies currently being explored to treat osteoarthritis (OA).

Materials & Methods: This retrospective case study observed ten patients (13 knees) with severe knee OA who failed extensive conservative treatment and were treated with BMA injection using a novel, pure bone marrow aspiration (pBMA) technique.

Results: No adverse events were reported. More than 50% reduction in the visual analog scale score for pain was observed at 2- and 12-weeks post-procedure, showing statistical significance. At 64 ± 26 weeks post-procedure, average knee pain remained significantly less than pre-procedure.

Conclusion: Therefore, patients with severe knee OA may achieve significant relief after a BMA injection obtained using this pure bone marrow aspiration technique.


The Marrow Cellution™ System is designed to minimize and eliminate the restrictive limitations associated with “point of care” processing systems which employ inefficient traditional aspiration trocar technology and are regulated as drugs “Advanced Therapies Medicinal Products (ATMP)”.  Marrow Cellution™ is a minimally invasive bone/cell enriched autograft access and retrieval system, which does not require additional manipulation or processing, it never leaves the sterile field and provides rich autograft without associated morbidity.
