Comparison between suture anchor and transosseous suture for the modified-Broström procedure.
BACKGROUND
This prospective, randomized study was conducted to compare clinical outcomes of the modified Broström procedure using suture anchor or transosseous suture technique for chronic ankle instability.


METHODS
Forty patients were followed for more than 2 years after modified Broström procedure. Twenty procedures using a suture anchor and 20 procedures using a transosseous suture were performed by one surgeon. The clinical evaluation consisted of the Karlsson scale and the Sefton grading system. Talar tilt and anterior talar translation were measured on anterior and varus stress radiographs.


RESULTS
The Karlsson scale had improved significantly to 90.8 points in the suture anchor group, and to 89.2 points in the transosseous suture group. According to Sefton grading system, 18 patients (90%) in suture anchor group and 17 patients (85%) in transosseous suture group achieved satisfactory results. The talar tilt angle and anterior talar translation improved significantly to 5.9 degrees and 4.2 mm in suture anchor group, and to 5.4 degrees and 4.1 mm in transosseous suture group, respectively.


CONCLUSIONS
No significant differences existed in clinical and functional outcomes between the two techniques for ligament reattachment. Both modified Broström procedures using the suture anchor and transosseous suture seem to be effective treatment methods for chronic lateral ankle instability.
