PROMIS Scores for Chronic Plantar Fasciitis Before and After Gastrocnemius Recession

Abstract

Category: Ankle; Hindfoot Introduction/Purpose: There has been an established relationship between increased loading on the Achilles tendon and tension on the plantar fascia. This supports the idea that either tight gastrocnemius and soleus muscles or contractures of the Achilles tendon are risk factors for plantar fasciitis. Gastrocnemius recession has gained popularity as a viable surgical intervention for cases of chronic plantar fasciitis due to isolated gastrocnemius contracture. To our knowledge, this is the first study to investigate PROMIS scores in patients with plantar fasciitis before and after gastrocnemius recession. Methods: The Electronic Medical Record was queried for medical record numbers associated with Current Procedural Terminology code 27687 (gastrocnemius recession). Our study included all patients with a preoperative diagnosis of chronic plantar fasciitis with treatment via isolated gastrocnemius recession with one-year minimum follow-up. 40 patients were included in our study. Patient variables were collected via chart review. Preoperative and postoperative PROMIS scores were collected in the clinic. Results: Preoperative and postoperative PROMIS scores improved for physical function and pain interference from 39.27 and 62.78 to 44.54 and 56.5 (p=0.0005, p=0.0001) respectively, PROIMS Depression scores were not significantly different (p=0.6727). VAS scores significantly decreased from 7.05 to 1.71 (p < 0.0001). Patients with preoperative peripheral neuropathy had significantly lower improvement in PROMIS physical function scores (p=0.0029). Tobacco use led to significantly lower improvement in in PROMIS depression (p=0.0202). Conclusion: Gastrocnemius recession is an effective option for patients with refractory pain in plantar fasciitis. Our PROMIS and VAS data confirm this procedure's utility and highlight its ability to significantly decrease pain and improve physical function in patients with chronic plantar fasciitis. We believe we have added to the literature by incorporating the, inherently superior, PROMIS scores. Based on the results of this study, the authors recommend gastrocnemius recession for patients who fail conservative management for plantar fasciitis.
