Background: Plantar fasciitis is one of the most common causes of foot pain among the population. This study aimed to review outcomes in patients undergoing Minimally invasive surgery (MIS) ultrasound-guided percutaneous plantar fasciotomy for the treatment of chronic plantar fasciitis.
Methods: A multicenter retrospective chart review of patients undergoing MIS using the Tenex device from January 2020 to December 2022. The main data points collected were Patient-Reported Outcomes Measurement Information System (PROMIS), follow-up times, revision surgery, and complications.
Results: 56 patients underwent 60 surgeries. The average age and BMI were 48.6 years (19-80), and 33.2 kg/m2 (19.7-58.6). The average follow-up was 27 months (13.3-48.6). The average improvement in pain, physical function, and mobility PROMIS scores were 5.2 (P < 0.01), 3.6 (P = 0.01), and 3.1 (P = 0.01).
Conclusion: MIS ultrasound-guided plantar fasciotomy appears to be a reliable surgical treatment option for chronic plantar fasciitis with high patient satisfaction and safety profile.
Level of evidence: IV.
