Ultrasound-Guided Percutaneous Fasciotomy and Debridement for Chronic Plantar Fasciopathy: Six-Year Patient-Reported Outcomes from a Retrospective Case Series.

BACKGROUND

Ultrasound-guided percutaneous fasciotomy and debridement (USPFD) is a minimally invasive treatment for patients with plantar fasciopathy refractory to conservative management. Previous studies have shown clinical improvement with USPFD, but pain relief and patient satisfaction have not been demonstrated beyond 2 years.

METHODS

This retrospective case series included patients who underwent USPFD at a quaternary academic medical center between April 2013 and January 2018, with refractory plantar fasciopathy and at least 4 years' follow-up. Patient outcomes were assessed through electronic surveys and telephone interviews. Primary outcome measures included mean changes in visual analog scale pain (VAS-Pain) scores and patient satisfaction via Likert scale. Secondary measures included VAS-Pain with the first 5 steps, VAS-Pain during daily weightbearing, and procedural complications.

RESULTS

Seventy unique procedures were identified among 62 patients. Follow-up data were obtained from 51 of 62 patients (82%) who responded to surveys or phone calls. This corresponded to 58 of 70 procedures (83%) at a mean postprocedure follow-up of 6.6 ± 1.4 years. Patients had a mean duration of symptoms of 2.1 ± 3.0 years prior to the procedure. Baseline VAS-Pain was 6.8 ± 2.2 and final follow-up VAS-Pain was 0.7 ± 1.1. At the last follow-up, patient-reported VAS-Pain with first 5 steps was 0.9 ± 1.6 and VAS-Pain with weightbearing through the day was 1.3 ± 1.8. Overall, 91% (53/58) of the procedures were considered successful, where patients responded they were "satisfied" or "very satisfied" and 52 of 58 (90%) procedural responses indicated that based on the outcome, they would recommend the procedure to others. Final follow-up VAS-Pain, VAS-first 5 steps, and VAS-weightbearing, were all improved in the success vs failure groups (P ≤ .002). No complications were reported.

CONCLUSION

USPFD was associated with high patient satisfaction and durable pain relief for chronic plantar fasciopathy at an average follow-up of 6.6 ± 1.4 years.
