Richard O’Connor, M.D. Research Award Paper: Prospective Randomized Trial of Rotator Cuff Repair Augmented with Bone Marrow Aspirate Concentrate

To comparatively examine clinical outcomes (i.e. patient-reported and tendon healing) after arthroscopic rotator cuff repair (ARCR) with without augmentation bone marrow aspirate concentrate (BMAC). Patients aged 18-70 undergoing ARCR for a full-thickness tear of the supraspinatus were enrolled randomized in one two groups. The treatment group received BMAC harvested from iliac crest injected at RCR site completion using Arthrex Angel System. control sham incision to maintain blinding. assessed preoperatively 3 months, 6 1 year, 2 years post-operatively physical exam patient reported (SST, ASES, VR/SF-12). MRI was performed 1-year postoperatively graded accordance Sugaya classification system. Statistical analysis conducted Student T-Tests chi-squared analysis. Eighty-two patients prospectively (control: 43, BMAC: 39). There significantly more males than females (p<0.05) as well higher baseline SST scores injection (p=0.0368) (Table 1). ASES improved both groups all time points post-operatively, 12 24 months compared (p<0.05). Mean score (3.50±1.07) that (2.60±0.88, p=0.003). A strong association noted between lower Suguya post-op (?2=10.077, p=0.002, Cramer’s V = 0.498). Bone into shoulder shows quality on post-operative based score, suggesting application may positively impact healing rates.
