The etiology of plantar fat pad atrophy may be age-related, due abnormal foot mechanics, steroid use, or collagen vascular disease. Displacement or atrophy of the fat pad can lead to osseous prominences in the forefoot that may be seen with painful skin lesions. Disease states, such as diabetes, may have loss of soft tissue integrity. Fat pad atrophy, regardless of the etiology, may result in significant pain, epidermal lesions, or metatarsalgia. In sensate patients, the pain can lead to emotional and physical pain, leading to productivity and financial losses. It is well documented that plantar pressure is directly correlated with plantar tissue thickness, with the loss of plantar fat being a fundamental mechanism for pressure related foot disorders.Autologous fat grafting to areas of plantar fat pad atrophy may reduce plantar pressures, and thus serve as a treatment for metatarsalgia, corn and callus prevention, and possibly ulcer prevention in diabetics. Plastic surgeons, with significant skills in fat grafting, can make a significant contribution. Current treatment modalities for fat pad atrophy include silicone injections, fat injections, and other temporary fillers; however, no objective studies using autologous fat have been performed. Approximately 30 adults who experience pain from fat pad atrophy, will have the option to participate. Through a randomized, controlled, cross-over study, some patients will receive autologous fat grafting, while some will receive standard of care podiatric treatment, then cross-over to fat grafting treatment after a year. Through pedobarograph and ultrasound assessments, the focal pedal pressure and tissue thickness following treatment will be documented over two years. We hypothesize that fat grafting for areas of increased pedal pressure in well-controlled diabetics will help decrease foot pressure during gait and increase soft tissue thickness on the foot pad, ultimately reducing pain. We also hope to demonstrate that by using autologous fat with evidence-based fat transfer techniques, results may be durable. This pilot study will help build new collaborative efforts between Foot and Ankle Surgery, Podiatry and Plastic Surgery, combining expertise in foot biomechanics with reconstructive fat grafting.
