OBJECTIVE This study presents the results of arthrodesis of the ankle in non-inflammatory osteoarthritic conditions. METHODS 34 open arthrodeses (33 patients) were followed for 5.5 +/- 3.2 years after surgery. At follow-up clinical results were evaluated by the Kitaoka and Gruen scores and standing X-rays were analysed for the talo-calcaneal angle and the grade of arthrosis. RESULTS Patients expressed high and very high satisfaction in 84 % of the cases; good results were higher with the Gruen score (79 %) than with the Kitaoka score (50 %). The patients did not complain pain but had some limitation in walking distance; gait was compensated in 44 % of the patients. A significant increase of arthrosis in adjacent joints could not be observed. A pseudoarthosis was observed in four cases and minor, conservatively treated complications arose in seven cases. CONCLUSIONS We conclude that, on the basis of these results, arthrodesis of the ankle still has a place in therapy due to the high patient satisfaction.
