Differences in Postoperative Outcomes of Common Foot and Ankle Procedures Performed by Orthopedic Surgeons and Podiatrists

Category: Ankle; Midfoot/Forefoot Introduction/Purpose: In the United States, there has been a substantial rise in podiatrists to address the increasing prevalence of foot and ankle pathologies. Although this may improve accessibility to foot and ankle care, there may be differences in the quality of care delivered by podiatrists compared to orthopedic surgeons. Some studies have found that patients treated by podiatrists have higher postoperative complication rates and length of hospital stay. With a growing emphasis on patient-centered care, there is a need for research investigating these differences so patients can make informed decisions when selecting providers. The purpose of our study is to compare postoperative complications in common foot and ankle procedures performed by orthopedic surgeons and podiatrists. Methods: A national database was queried to identify patients 18 years and older who underwent forefoot surgery (including fusion and bunionectomy), hindfoot or midfoot fusion, rotational ankle fracture fixation, ankle arthrodesis, or ankle arthroplasty from 2009-2022. Provider variable codes were then utilized to identify patients who underwent the corresponding procedures by orthopedic surgeons and podiatrists. Univariate analyses and multivariate logistic regressions were performed to compare 90-day rates of medical and surgical complications between the two provider categories for each procedure while controlling for age, sex, diabetes, smoking, and obesity. Results: Overall, 34,807 patients underwent foot and ankle (F&A) procedures by an orthopedic surgeon and 43,787 patients by a podiatric surgeon. Orthopedic patients were older (51.77 versus 50.79; p< 0.001), had a higher comorbidity index (Charlson Comorbidity Score 1.13 versus 0.97; p< 0.001), and were more likely to undergo surgery from an inpatient facility (16.18% versus 2.18%; p< 0.001). Comparing 90-day complication rates, podiatry patients exhibited higher rates of complications, including neuritis, nonunion, prosthetic complications, and wound debridement across various procedures when compared to orthopedic surgeons. Conclusion: Common foot and ankle procedures performed by podiatrists may be associated with higher postoperative complications affecting quality of care which could be attributed to differences in training, case volume and variety, and surgical techniques between orthopedic surgeons and podiatrists. Although access to foot and ankle procedures has improved, these data raise questions about the safety of procedures performed by podiatrists. Thus, additional highly powered studies are needed to investigate these postoperative differences to ensure that patients have all the information necessary to make informed decisions regarding their care.
