A single dose of platelet-rich plasma improves the organization and strength of a surgically repaired rotator cuff tendon in rats.
RatWoundWistarMalen = 44 Wistar rats in two groups, with 12 rats per group for bi…Intra-articular injection into the shoulderSingle dose, volume not statedImmediately after the surgical repair
Model: Experimental acute rotator cuff tear with surgical suture repair, assessed at 3 weeks
Platelet-rich plasma increased maximal load (p < 0.001) and stiffness (p < 0.005), improved Bonar score (p = 0.018) and collagen organisation by birefringence (p = 0.002) at 3 weeks, with no difference in vascularity.
