Ellis Jones technique as a cost-effective treatment for chronic peroneal tendon subluxation: A case report.

Abstract

Rationale: Peroneal tendon subluxation is an uncommon injury that is often overlooked during the acute phase, resulting in long-term instability.

Patient concerns: We present a case involving a 25-year-old male soldier with a 2-year history of recurrent ankle pain and instability following an initial ankle injury.

Diagnoses: Chronic peroneal tendon subluxation was diagnosed based on clinical examination and imaging findings.

Interventions: Given the limitations of surgical instruments available at our institution in Vietnam, the patient was treated operatively using the Ellis Jones method, a traditional technique. The superior peroneal retinaculum was reinforced with a part of the Achilles tendon. Postoperatively, the leg was immobilized in a below-knee cast for 6 weeks.

Outcomes: The patient experienced an uncomplicated recovery, returning to work without pain or need for braces within 2 months and resuming full physical activity 6 months postoperatively.

Lessons: This case highlights that the Ellis Jones method remains a simple, cost-effective, and reliable surgical option for managing chronic peroneal tendon subluxation, particularly in resource-limited settings where specialized implants are unavailable.
