Main idea: Platelet-rich plasma is a valuable and safe treatment dressing for chronic nonhealing ulcers; it is simple to prepare and has remarkable effects.
Several randomized controlled trials comparing platelet-rich plasma to standard wound care for chronic wounds have been published. Previous articles have revealed that the role of platelet-rich plasma in promoting chronic wound healing is uncertain. This quantitative meta-analysis was conducted to evaluate whether superior outcomes can be obtained by using platelet-rich plasma in nonhealing ulcers compared with traditional wound care.
Results: Overall, 630 adult patients in 15 randomized controlled trials from 2000 to 2018 were included. The number of ulcers healed in the platelet-rich plasma group was higher than in the control group, and the difference was statistically significant . During the fourth week of follow-up, the number of ulcers healed in the platelet-rich plasma group was significantly greater than in the control group.
