The use of biologics for the elbow: a critical analysis review.

There is significant interest in biologic treatment options to improve the healing environment and more rapidly decrease symptoms in many conditions around the elbow. Despite fairly widespread use of biologic agents such as platelet-rich plasma (PRP) in the elbow, there is a lack of clear evidence in the literature to support its use. The potential impact of these biologic agents must be evaluated with evidence from high-quality studies, particularly considering the high financial burden these treatments often impose on patients. The aim of this review is to provide an evidence-based summary of the biologic augmentation options available for use by the physician treating painful conditions of the elbow and to identify areas where further research is warranted.
