Abstract

Background: Müller Weiss disease is a rare disease characterized by collapse of the lateral part of the navicular, outwards protrusion of the talar head and peri-navicular osteoarthrosis. We review the result of six patients treated by arthroscopic triple arthrodesis.

Methods: Since 1998, arthroscopic triple arthrodesis was performed in six feet with Müller Weiss disease. The arthroscopic findings were analyzed. The feet were graded by the pre-operative X-rays according to Mareira classification. The consolidation of the triple arthrodesis was assessed by the post-operative X-rays of the operated feet. The clinical outcome was assessed by the modified AOFAS ankle-hindfoot scale.

Results: All the operated feet fused solidly. The average time for solid fusion was 21 weeks (16-22 weeks). The overall American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was 81.5.

Conclusions: Arthroscopic triple arthrodesis is an alternative surgical treatment in management of Müller Weiss disease resisted to conservative treatment.

Level of evidence: Level 4 therapeutic study.
