Abstract

INTRODUCTION:

This study aimed to evaluate the clinical outcome of simultaneous less-invasive ankle arthroscopy and hindfoot endoscopy for combined anterior ankle impingement syndrome (AAIS) and posterior ankle impingement syndrome (PAIS) in professional athletes.

MATERIALS AND METHODS:

Between October 2009 and October 2011, 12 feet of 9 professional athletes (8 men, 1 woman; mean age 25 years; range 19-34 years) with combined AAIS and PAIS underwent simultaneous ankle arthroscopy and hindfoot endoscopy. Radiography, computed tomography, and magnetic resonance imaging were performed in all patients. Ultrasound-guided anesthetic injection was administered for the diagnosis of PAIS. Active plantar and dorsal flexion angles of the ankle before and after surgery, occurrence of complications, and time to return to competitive sports were evaluated.

RESULTS:

All feet had osteophytes in the anterior ankle joint. Ostrigonum and a large posterior talar process were found in 8 and 4 feet, respectively. Combined disorders that were noted were lateral ankle instability in 6 feet and an osteochondral lesion of the talus in 4 feet. Median JSSF and VAS scores improved significantly from 63 (range 55-69) points preoperatively to 82 (range 77-100) points postoperatively (p < 0.01), and from 85 (range 70-95) points preoperatively to 8 (range 3-15) points postoperatively (p < 0.01), respectively. Median active plantar and dorsal flexion angles improved significantly from 40° (range, 30°-50°) and 10° (range 5°-20°) preoperatively to 50° (range 40°-55°) and 15° (range 10°-20°) postoperatively, respectively (p < 0.01 and p < 0.05, respectively). One patient complained of numbness in the vicinity of the sural nerve, which resolved spontaneously by the 4th week after surgery. Median time to return to competitive sports was 12 (range 12-15) weeks.

CONCLUSION:

Simultaneous ankle arthroscopy and hindfoot endoscopy for combined AAIS and PAIS enables professional athletes to return to athletic activity.
