"Our study on 79 patients who received platelet-rich plasma with a fibrin matrix (PRFM) demonstrated no real differences in healing in a tendon-to-bone rotator cuff repair. In fact, this preliminary analysis suggests that the PRFM, as used in this study, may have a negative effect on healing. However, this data should be viewed as preliminary, and further study is required," said Rodeo.
Researchers divided 79 patients into two groups. One received PRFM and the other did not. The doctors used standardized rotator cuff repair techniques on all patients along with post-operative rehabilitation protocols. "It [the PRFM] is almost like chewing gum in consistency," Rodeo said. "In rotator cuff repair, we attached it to a suture which was used to reattach the tendon to the bone."
