Orthop J Sports Med . 2021 Sep 1;9(9):23259671211024937.Thirty two patients with partial supraspinatus tears were randomized to receive a platelet-rich plasma (PRP) intratendinous injection (n=16) or a subacromial corticosteroid injection (n=16). The outcomes of interest were pain as measured by the Visual Analogue Scale (VAS) and function measured by the Oxford Shoulder Score (OSS). There was no significant differences in VAS or OSS scores between the two groups at 1-month follow-up. The PRP group demonstrated significantly improved VAS and OSS scores at 6 months follow-up. There were no complications in either group.
