Summary
The modified Evans procedure offers a reliable, long-term solution for chronic lateral ankle instability, with 85% of patients reporting satisfactory outcomes after an average of 12.6 years. This surgical technique effectively restores function for both recreational and competitive athletes.
Area of Science:
- Orthopedics
- Sports Medicine
- Surgical Outcomes
Background:
- Chronic lateral ankle instability affects many individuals, with over 50 surgical procedures described.
- Anatomic repairs are gaining favor based on short-term studies, but long-term patient-oriented outcomes require further investigation.
Purpose of the Study:
- To evaluate the long-term patient-oriented outcomes of the modified Evans procedure for chronic lateral ankle instability.
Main Methods:
- A long-term (7-20 years) analysis of 20 patients who underwent a modified Evans procedure.
- Patient outcomes assessed using a modified American Academy of Orthopaedic Surgeons questionnaire, evaluating satisfaction, activity levels, stability, pain, and willingness to repeat the procedure.
- Assessment of patient ability to perform recreational or competitive sporting activities pre-injury, 1 year postoperatively, and at present time.
Main Results:
- 95% of patients reported satisfactory outcomes at 1 year post-surgery, with 85% satisfied at long-term follow-up.
- Among competitive athletes, 50% returned to their pre-injury level of sport, while 87.5% of recreational athletes achieved this.
- The modified Evans procedure demonstrated reliable and effective long-term results for chronic lateral ankle instability.
Conclusions:
- The modified Evans procedure is a reliable and effective treatment for chronic lateral ankle instability, demonstrating sustained patient satisfaction and functional improvement over time.
- While effective for many, elite athletes might benefit from procedures based on anatomic repair principles, though long-term data for such methods are still limited.
