| Popis: | Category: Sports; Ankle Introduction/Purpose: Because modified Broström procedure for chronic ankle instability provides a restoration of mechanical stability by reinforcing attenuated host tissue, poor quality of remnant ligamentous tissue can be considered as a prognostic factor for anatomic ligament repair surgery. The aim of this study was to evaluate the intermediate-term clinical outcomes after anatomic lateral ligaments repair augmented with suture-tape for chronic ankle instability with poor quality of ligament remnants. Methods: Thirty-six patients with the insufficient lateral ligament remnants confirmed by preoperative magnetic resonance image and intraoperative inspection were followed for more than 3 years after the augmented Broström repair. The clinical evaluation consisted of the Foot and Ankle Outcome Score(FAOS), Foot and Ankle Ability Measure(FAAM). Measurements on stress radiographs were performed to evaluate the changes of mechanical instability. To identify the changes of functional ankle instability, postural control ability was evaluated using single leg stance test with eyes closed. Results: FAOS and FAAM scores had significantly improved from preoperative average 56.3 and 51.8 points to 90.2 and 88.5 points at final follow-up, respectively (p < .001). Talar tilt angle and anterior talar translation had significantly improved from preoperative average 16.3° and 13.2 mm to 3.5° and 4.3 mm at final follow-up, respectively (p < .001). Balance retention time had significantly improved from preoperative average 3.8 seconds to 6.6 seconds at final follow-up (p < .001). Complications included two wound problems (one with superficial infection and one with marginal necrosis) and one superficial peroneal nerve injury with temporary paresthesia. Although 8 patients sustained an ankle sprain after operation, only 1 patient(2.8%) showed a recurrence of subjective and mechanical instability. Conclusion: Modified Broström procedure augmented with suture-tape appears to be an effective alternative for chronic ankle instability with poor quality of ligament remnants. Through the suture-tape augmentation and the direct repair of attenuated ligaments, this combined procedure can provide reliable stability and advantages of the anatomic ligament repair. |
