Radiofrequency microtenotomy is as effective as plantar fasciotomy in the treatment of recalcitrant plantar fasciitis

- Radiofrequency microtenotomy is as effective as plantar fasciotomy in the treatment of plantar fasciitis.
- There is no additional benefit in performing both procedures concurrently.
- Patients undergoing both procedures tended to be older and experienced a higher rate of complications.

BackgroundRadiofrequency microtenotomy (RM) is effective for treating plantar fasciitis. No studies have compared it to the plantar fasciotomy (PF). We hypothesized that RM is equally effective and provides no additional benefit when performed with PF.MethodsBetween 2007 and 2014, all patients who underwent either or both procedures concurrently at our institution were analyzed. Data collected included demographics, SF-36 Health Survey, AOFAS Ankle-Hindfoot Scale, and two questions regarding satisfaction and expectations, all of which were assessed pre-operatively and post-operatively at 6-months and 1-year. ANOVA with Bonferroni correction was used to compare scores at each interval. Logistic regression was used to identify pre-operative factors that predicted for satisfaction and expectations.ResultsThere were no differences in patient outcomes. No pre-operative factors predicted for satisfaction and expectations.ConclusionsRM is as effective as PF in the treatment of plantar fasciitis. Patients who underwent both procedures experienced no benefit and a higher rate of complications.
