Abstract

Purpose: We retrospectively evaluated the characteristics of these patients and the effectiveness of ankle arthrodesis in the treatment of ankle arthritis caused by Kashin-Beck disease (KBD).

Methods: A retrospective study of KBD patients with ankle osteoarthritis who underwent ankle arthrodesis between December 2012 and January 2022 was performed. A total of 46 patients were included. The general characteristics, clinical manifestations and imaging features of the patients were recorded and summarized. measured using the VAS score, and ankle function was assessed by the AOFAS ankle-hindfoot score.

Results: Multiple subchondral cystic changes were found in 42(91.3%) patients. The VAS scores for both resting and weight-bearing conditions were 6.28 ± 1.30 vs. 2.09 ± 1.12 (P < .001) and 6.87 ± 1.01 vs. 2.17 ± 0.98 (P < .001), respectively. The AOFAS scores were 59.17 ± 5.50 and 88.39 ± 1.42, respectively (P < .001).

Conclusions: The subchondral multiple cystic transformation of the ankle KBD has a certain suggestive role.Arthrodesis is an effective method to reduce ankle pain and improve ankle function in KBD patients with ankle osteoarthritis.

Keywords: Arthrodesis; Kashin-Beck disease; Osteoarthritis; Subchondral cystic change.
