Bone marrow aspirate concentrate augmentation of the bone-patellar tendon-bone allograft during ACL reconstruction may yield greater signal intensity scores on MRI at 3 months postoperatively, according to published results.
Researchers randomly assigned 80 patients undergoing ACL reconstruction with bone-patellar tendon-bone allografts to receive either an injection of bone marrow aspirate concentrate (BMAC) into the bone-patellar tendon-bone allograft (BMAC group) or a small sham incision made at the iliac crest (control group). To determine the signal intensity ratio of the ACL graft,
