Summary

This study compares the efficacy and safety of poly-L-lactic acid (PLLA) threads versus platelet-rich plasma (PRP), both combined with subcision, in the treatment of post-traumatic atrophic scars. Patients with post-traumatic atrophic scars were allocated to either a single session of subcision followed by PLLA thread insertion or four monthly sessions of subcision combined with PRP injection. Clinical improvement, patient satisfaction, adverse effects, and histopathological changes were assessed during a 3-month follow-up period.
