Abstract
INTRODUCTION: Chronic wounds are defined as wounds that have failed to proceed through the orderly process that produces satisfactory anatomic and functional integrity or that have proceeded through the repair process without producing an adequate anatomic and functional result. The majority of wounds that have not healed in three months are considered chronic, although a duration as low as four weeks has been used to indicate chronicity. Our study aimed to compare the efficacy of autologous platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) versus standard cleaning and dressing as a regenerative medicine strategy to promote healing in chronic wounds. METHODS: A prospective randomized controlled trial was undertaken to test the efficacy of autologous PRP and PRF in the healing of chronic wounds. A series of 60 cases was compiled from patients attending the outpatient department regularly for the management of chronic wounds. A total of 30 cases were randomly chosen for study with autologous PRP and PRF and 30 cases received conventional dressing. RESULTS: The average healing duration in the study was significantly shorter for the PRP & PRF group. The mean healing time for this group was 4.45 weeks (31.2 ± 3.07 days) compared to 9.61 weeks (67.27 ± 9.19 days) for the conventional dressing group. CONCLUSION: PRP and PRF belong to a new generation of platelet concentrates that help efficaciously for enhanced healing and functional recovery, safely and cost-effectively. They help by shortening the recovery period overall, improving the quality of life of patients, and altogether eliminating the additional morbidity of operative procedures.
