Remission Strategies with Fat Grafting to Prevent Recurrence of Pedal Ulcerations and Pain: A Case Series.

Background: Foot deformities and gait abnormalities can result in locally elevated peak pedal pressures or atypical pedal biomechanics. Combined with underlying comorbidities such as neuropathy, stroke, atrophic fat padding and history of ulcerations, this can lead to recurrent ulcerations and pain. Pedal fat grafting (PFG) is a treatment modality that has been shown to reduce peak pressures and accelerate wound healing. This study aimed to investigate the utility of PFG to treat and prevent ulcerations. Methods: We retrospectively analyzed medical history, demographics, wound volume at time of procedure, volume of fat injected, surgical outcomes, and presence of new wounds in 15 patients who underwent PFG at Keck Hospital between 2018 and 2023. Results: Seventeen feet from 15 patients (63 ±â€…12 years old, body mass index 30.9 ±â€…3.1) received PFG with an average volume of fat injected of 10.7 mL and procedure time of 84.6 minutes. At the time of PFG, nine wounds were present on nine feet with an average wound volume of 1.6 ±â€…2.7 cm3. Average follow-up was 6.9 months (range 1-36 months), with no complications or recurrent ulcerations since the procedure. Conclusions: PFG is a promising treatment option for reducing peak pedal pressure and preventing ulcer recurrence in patients with various conditions. Further study is warranted for long-term follow-up.
