Abstract
Background
Platelet-rich plasma (PRP) has shown promising results for adhesive shoulder capsulitis (AC) in pre-clinical models. The aim of this review is to investigate the clinical outcomes of using PRP in AC.
Materials and Methods
We conducted a systematic scoping review of the literature using bibliographic databases from inception until the 9th of January 2022 [PubMed, Web of Science, Scopus, and CENTRAL]. Randomized studies were included if they investigated the use of PRP in human patients with a diagnosis of AC. Authors performed individual study quality assessments using the RoB 2 tool.
Results
We screened a total of 470 results and 6 were included in the final synthesis. Studies included data of 578 patients with 263 patients receiving PRP (45.5%). All studies used PRP as part of non-operative treatment. PRP was compared to another intervention in all six studies. Four of these studies found PRP to be more effective. No major adverse effects were reported in any study.
Conclusion
PRP is a safe treatment option that can be added to the investigative treatment arsenal of AC. Despite showing some favorable results, several limitations and patient-centered questions remain to be addressed by future studies.
Level of Evidence
IV.
