We hypothesized that SSRI has a positive effect on the healing of the boneโ€“tendon interface (BTI). Improved rotator cuff tear healing was confirmed via mechanical strength measurements and histological assessment of the restored tendon. METHODS Forty male adult Spragueโ€“Dawley wild-type rats were used in this study. The animals were divided into two groups: group-SSRI (supraspinatus [SSP] repair with SSRI injection) and group-C (conventional SSP repair only without SSRI injection). Biomechanical and histological analyses were performed 8 weeks after the index rotator cuff surgery. RESULTS The ultimate load (N) was significantly higher in group-SSRI than in group-C (54.8 ยฑ 56.9 vs 25.1 ยฑ 11.1, P = 0.031). In the histological evaluation, the Bonar score confirmed significant differences in collagen fiber density (group-C: 0.1 ยฑ 0.6, group-SSRI: 0.6 ยฑ 0.5, P = 0.024), vascularity (group-C: 0.1 ยฑ 0.2, group-SSRI: 0.3 ยฑ 0.4, P = 0.024), and cellularity (group-C: 1.7 ยฑ 0.4, group-SSRI: 2.0 ยฑ 0.0, P = 0.023) between the groups. Based on the total score, group-SSRI was found significantly better than group-C (6.3 ยฑ 2.7 vs 4.3 ยฑ 1.9, P = 0.019). CONCLUSION Our model showed improved biomechanical and histological outcomes of healing in group-SSRI 8 weeks after rotator cuff repair, suggesting that SSRI improved healing and facilitate rotator cuff repair.
