Brief summary
Investigators designed this prospective cohort study to compare the clinical outcomes of modified Broström operation and anatomical reconstruction for the treatment of CLAI and GJL.
Detailed description
The modified Broström operation is still the first line to treat chronic lateral ligament instability (CLAI). However, some studies indicate the modified Broström operation may bring a higher rate of re-injury in generalized joint laxity (GJL). Anatomical reconstruction was reported to generate similar results and less rate of re-injury compared in patients with CLAI. However, the clinical outcomes of the two operations are not discussed in CLAI and GJL. So, investigators designed this prospective cohort study. The primary outcomes are Karlsson, Foot and Ankle Outcome Score (FAOS), and Foot and Ankle Ability Measure (FAAM) scores. The secondary outcomes are anterior displacement and talar tilt angle in stress radiography, the rate of re-injury.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Karlsson score | postoperative Karlsson score at 1 year. | This score is a primary scale for lateral ankle instability |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Anterior displacement and talar tilt angle in stress radiography | postoperative radiographic measures at 2 years. | The outcomes are common indicators for evaluation the lateral stability of ankle |
Other
| Measure | Time frame | Description |
|---|---|---|
| Rate of re-injury | the rate of re-injury at 2 years. | After surgery, the rate of patients re-sprain |
| Signal to noise value of the anterior talofibular ligament | 6 months post-treatment | Signal to noise value of the anterior talofibular ligament |
