Good rate of satisfaction but suboptimal clinical outcome at long-term follow-up in a large series of patients who had operative stabilization of the deltoid ligament of the ankle.

PURPOSE

To report results following deltoid ligament reconstruction in a large series of patients.

METHODS

For consecutive patients who had a medial ankle ligament stabilization 2010-2018 information from their medical files was registered, and they were invited for follow-up in 2021-2022. They answered questions about satisfaction with the treatment and current symptoms, and they completed the Foot and Ankle Measurement (FAAM) questionnaire.

RESULTS

Of the 503 patients, 342 (68%) had a history of trauma to the ankle and 114 (23%) had previous ankle surgery. 67% had other procedures (besides synovectomy) simultaneous to medial ligament reconstruction. 269 patients (54%) responded to the invitation for follow-up. For 182 (71%) of the responders, the operation solved their ankle problems. 163 (63%) were satisfied with the surgery. 192 (71%) would repeat the operation. 173 (67%) had pain in the ankle during the past week, and 86 (50%) of these were not able to run. FAAM ADL-scores were significantly higher than in a mixed group of ankle/foot patients but not normal.

CONCLUSION

The relatively high degree of satisfaction despite suboptimal clinical results may reflect the complex nature of the deltoid ligament insufficient ankle. It is concluded that repair or reconstruction of the deltoid ligament is only performed in patients reporting ankle instability and with peroperatively demonstrated medial instability and pathology to the ligament.

LEVEL OF EVIDENCE

Level III.
