Possibilities and limitations of electrospun chitosan-coated polycaprolactone grafts for rotator cuff tear repair.
RatOtherLewisMalen = 51 rats in total, 17 per group (3 groups); 12 per group for…Surgical implantation at the repaired infraspinatus enthesis together with suture fixationAt the second (repair) surgery, 4 weeks after tendon detachment
Model: Chronic rotator cuff tear model: left infraspinatus tendon detached, followed 4 weeks later by repair surgery
Biomechanical parameters did not differ significantly between the CS-g-PCL and polyurethane implant groups, and median force at failure in both implant groups was lower than in the suture-fixed group. Histologically the CS-g-PCL implant showed no acute inflammation, good cell infiltration, ingrowth…
