The discussion after these presentations centered around what type of PRP to use for what indications. It is clear that we need better data. The best published clinical data for tendon related injuries and disorders right now supports the use of PRP that is concentrated to 4-5x baseline platelets with an increased concentration of WBCs. See PRP Reference List.
Most studies so far have NOT been well controlled. However, Dr. Randelli (from Milan, Italy) presented the preliminary results of his prospective randomized controlled trial showing how PRP at a concentration of 4-5x baseline with increased WBCs DECREASES pain after arthroscopic rotator cuff repair and may improve healing in small and medium sized tears. Excellent work.
Several papers, posters and presentations at the meeting supported the use of PRP for cartilage restoration. Level one human data (randomized controlled trials), does not yet exist.
