Platelet-rich plasma (PRP) is a new technology focused on enhancing the healing response after injury of different tissue types. PRP is prepared by withdrawal of patients' peripheral blood and centrifugation to obtain a highly concentrated sample of platelets, which undergo degranulation to release growth factors with healing properties. It also contains plasma, cytokines, thrombin, and other growth factors that are implicated in wound healing and have inherent biological and adhesive properties. ⋯ By acceleration of the biological integration of the graft by use of PRP, patients may undergo faster, more intensive rehabilitation programs and return to sports more rapidly. Because of its autogenous origin, easy preparation, and excellent safety profile, the advent of PRP has opened another therapeutic door for sports medicine physicians and orthopaedic surgeons. Future directions of PRP include improving the results of arthroscopic and related surgery, in addition to delineating correct dosage, timing, and quantification, as well as ideal techniques of PRP application.

The purpose of this study was to evaluate the results of posterior arthroscopic subtalar arthrodesis (ASTA) by use of a posterior 2-portal approach in the prone position and to describe the surgical technique. ⋯ ASTA in the prone position through a posterior 2-portal approach provided safe access and superior visualization of the posterior talocalcaneal facet and easy fixation of posterior screws. This technique also provided good clinical outcomes (good results in 81% of patients according to the Angus and Cowell scoring system and a mean modified AOFAS score of 84 points) and a 94% union rate at a mean of 11 weeks.
