LAS VEGAS — Use of bone marrow concentrate containing mesenchymal stem cells as an adjunct therapy showed significant improvement in healing outcomes after rotator cuff repair, according to data presented during the American Academy of Orthopaedic Surgeons Annual Meeting.
Results showed non-healing or retear diagnosed on ultrasound and confirmed by MRI among 34% of shoulders. Between the tendons that healed and those that showed deficient healing or a frank retear, the researchers found no significant difference in preoperative cuff tear size at the time of screening or during surgery, with an estimated average cuff tear size of 2.3 cm in the healing group and of 2.2 cm in the group without healing.
