Patient Reported Outcomes Following Triple Arthrodesis for Adult Acquired Flat Foot Deformity: Minimum Two Year Follow Up.

Publication/Presentation Date



The aim of this study is to analyze patient reported outcomes following this procedure as well as any demographics that may confer prognostic capability. A retrospective analysis was conducted of patients that underwent Triple Arthrodesis at our facility from 2014-2021. Patients were selected if they underwent an isolated triple arthrodesis. All cases included either a gastrocnemius recession versus a percutaneous tendo-achilles lengthening depending on the patient's Silverskiold examination. The electronic medical record was utilized to collect basic patient demographics, previous foot and ankle surgeries, hardware failures, additional procedures, and surgical complications. To evaluate outcomes, we compared Patient Reported Outcomes Measurement Information System (PROMIS) survey scores with the general population and pre-operative vs. post-operative Visual Analog Scale (VAS) scores. Foot Function Index (FFI) scores and scores were utilized as a validation tool for our results. One hundred and thirty two patients met the criteria for our study with a total of 50 participants completing the PROMIS and FFI surveys. The average time point at which the outcomes were collected was 5.50 years postoperatively, ranging from 1.65 to 7.57 years. The average PROMIS physical function was 38.35, pain interference was 61.52, and depression was 49.82 for this population. The mean FFI scores were 58.56 for pain, 60.07 for disability, 48.07 for activity limitation. There was a significant decrease in preoperative and postoperative VAS scores from 5.4 to 2.55 (p
