Summary
Chronic lateral ankle instability often involves associated injuries beyond ligament tears. Surgeons should investigate peroneal tendons, retinaculum, and anterolateral impingement for better treatment outcomes.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Anatomy
Background:
- Chronic lateral ankle instability frequently requires surgical intervention.
- Associated injuries often complicate treatment and affect outcomes.
Purpose of the Study:
- To identify the types and frequency of associated injuries in patients undergoing primary ankle lateral ligament reconstruction.
- To evaluate preoperative and intraoperative findings for common associated pathologies.
Main Methods:
- Retrospective review of 61 patients undergoing primary ankle lateral ligament reconstruction.
- Analysis of clinical history, physical exam, MRI, and intraoperative findings.
- Systematic inspection of peroneal retinaculum, peroneal tendons, and ankle joint.
Main Results:
- No isolated lateral ligament injuries were found; all patients had associated injuries.
- Common findings included peroneal tenosynovitis (77%), anterolateral impingement (67%), and attenuated peroneal retinaculum (54%).
- Other significant injuries included loose bodies (26%) and peroneus brevis tears (25%).
Conclusions:
- Patients with chronic lateral ankle instability exhibit a high incidence of associated injuries.
- Peroneal tendon pathology, retinacular issues, and anterolateral impingement are prevalent.
- A thorough evaluation for these associated injuries is crucial for optimizing treatment outcomes.
