Purpose
The aim of this study was to compare long-term outcomes after anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) repair and reconstruction at 5–10 years after surgery.
Methods
Forty-five patients who underwent surgical repair or reconstruction of both ATFL and CFL were retrospectively investigated in this study. American Orthopedic Foot and Ankle Society (AOFAS), Karlsson Score, and Tegner activity scale were used to evaluate the ankle function at a follow-up of 5–10 years. Ultrasound examination was used to evaluate the ATFL and CFL, and MRI was used to evaluate the cartilage.
Results
At final follow-up, no patient had recurrent ankle instability. There were no significant differences in AOFAS (92.6 ± 6.5 vs 89.6 ± 3.4; n.s.) or Karlsson Score (93 ± 8.2 vs 90.6 ± 5.0; n.s.) between the reconstruction group (twenty patients) and the repair group (twenty-five patients) postoperatively. There were also no significant differences in activity level as measured by the Tegner activity score (6 (range 4 to 8) vs 6 (range 5 to 7); n.s.). Five patients in the reconstruction group complained of some tightness of the ankles. Ultrasound showed the reconstructed ligaments maintained good continuity and were thicker than the repaired ligaments.
Conclusion
Patients in both the repair and the reconstruction cohort had high patient satisfaction with the outcomes and high function and activity levels that indicated recreational sports participation over a long period.
