“…described in literature regarding the use of PRP in the treatment of degenerative tendon diseases (1,33,34,37,38,43), such as rotator cuff tendinosis (41,42,43,44) or plantar fasciitis, and in particular the insertional tendon disease of the Achilles (45) and the patellar tendons (46,47,48). Wilson et al (84) evaluated, after PRP intra-tendinous injection, the intratendinous retention and distribution of injected substance, tissue morphology following injection and effect of intratendinous injection and fenestration demonstrating how PRP is not only feasible but remains in the tendon after the procedure with slight loss outside the tendon.…”
