High Prevalence of Obesity and Female Gender Among Patients With Concomitant Tibialis Posterior Tendonitis and Plantar Fasciitis.

UNLABELLED: The link between increased body weight and hindfoot complaints is largely based on correlation to single foot pathology. We retrospectively reviewed 6879 patients with tibialis posterior tendonitis (TPT), plantar fasciitis (PF), or both. Among patients with either TPT or PF, 1 in 11 (9%) had both. We then compared age, gender, and body mass index among these groups. Patients with both diagnoses were neither statistically older nor more obese than patients with single diagnoses. However, they were statistically more female. Given the overall high prevalence of obesity in the study population, we feel these data support the link between obesity and multiple foot pathology. LEVELS OF EVIDENCE: Prognostic, Level IV: Case series.
