Primary Outcome Measures:
- The clinical evaluation consisted of a VAS for pain, the Karlsson scale, and the Sefton grading system. [ Time Frame: during a minimum period of 2 years ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- Talar tilt and anterior talar translation were measured on anterior and varus stress radiographs. [ Time Frame: during a minimum period of 2 years ] [ Designated as safety issue: No ]
With With the increased number of participants in sports and leisure time activities, the incidence of ankle ligament injuries has been correspondingly increased. Various surgical methods have been reported for chronic ankle instability. Of these methods, the modified Brostrom procedure is currently used most frequently, and its excellent treatment outcomes have been reported. If there are any methods for obtaining a strong ligament fixation force which are both technically simple and safe, such methods would shorten the operative time and be helpful for surgeons with little experience in managing chronic ankle instability to obtain excellent treatment outcomes. In recent years, a procedure using a suture anchor, which is used for various types of ligament or tendon reconstructions, has been frequently performed. To date, however, few studies have reported clinical outcomes of suture anchor techniques and comparisons of clinical results between suture anchor techniques and other procedures. Given the above background, we prospectively compared the clinical outcomes between the bone tunnel and suture anchor techniques in the modified Brostrom procedure for chronic lateral ankle instability.
