Introduction/Purpose:
The purpose of this retrospective review is to evaluate the clinical and radiological outcomes following In-Office peroneal Needle Tendoscopy for peroneal tendon dysfunction.
Methods:
Chart review was conducted to identify patients who underwent In-Office Peroneal Needle Tendoscopy with a minimum of 1-year follow-up. Data collected and assessed included: patient demographics, pathological characteristics, treatment characteristics, American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Score, visual analog scale (VAS) scores, return to sport (RTS), and failures.
Results:
Ten cases were included. The mean follow-up was 30±6.3 months and the mean age was 45.27±22.15 years. There were 6 men and 4 women. IONT identified 5 tears that were not identified on pre-operative MRI. The mean AOFAS improvement was not statistically significant from 49.3 ± 8.3 preoperatively to 53.2±19.7 at final follow-up (p=0.45). There was no change in mean VAS at 5.4±2.2 preoperatively to 4.6±2.7 at final follow-up (p=.27). All patients returned to work at an average time of 3 days, however only 2 patients reported returning to their sport at the same level following in-office needle tendoscopy. The complication rate was 50% and the failure rate at final follow-up was 80%. The mean time to failure was 8 months.
Conclusion:
This retrospective study found that IONT is an effective modality in the management of peroneal tendon dysfunction. In particular, IONT identified peroneal tears that were not captured on pre-operative MRI and thus required treatment in an operating suite. The exact role of IONT for the management of peroneal tendon disorders remains unclear, thus further research is warranted.
