Three clinicians and researchers of the GRIIP (International Research Group on Platelet Injections), experts in sports medicine and rehabilitation, performed a comprehensive literature review of MEDLINE, searching for (1) rehabilitation protocols after PRP injection for chronic tendinopathy and (2) fundamental studies of tendon healing. This review highlighted the main points to be clarified to establish a standardized post\u2010PRP injection protocol. Fourteen points were identified, grouped into three dimensions (immediate postprocedure, rehabilitation, and follow\u2010up and resumption of sports\/activity). With a modified Delphi method, the propositions were submitted to a panel of 23 experts from five French\u2010speaking countries. The recommendations were classified as appropriate or not appropriate, with strong or relative agreement, or uncertain when consensus was not reached.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Ten recommendations (postprocedure avoidance of nonsteroidal anti\u2010inflammatory drugs, rehabilitation principles and timeline, follow\u2010up) were classified as appropriate: six with strong and four with relative agreement; four propositions regarding immediate postprocedure were deemed uncertain.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Agreement was reached for 10 of the 14 recommendations but with low level of evidence, mainly based on experts' opinion.
