The aim of this study was to evaluate the clinical and radiographic success of arthrolysis surgery and the risk of progression of osteoarthrosis at the ankle joint.
In a retrospective clinical and radiological study, with a minimum follow-up of 24 months, the pain level and quality of living were evaluated.
Following arthrolysis of the ankle joint, 16% of patients required ankle fusion within 2 years. Women had a higher quality-of-life in terms of Foot Function Index. Younger patients scored higher in both quality-of-life and function scores. Radiographic osteoarthrotic changes and the specific follow-up interval did not correlate with clinical outcome.
Fewer than 20% of patients required ankle fusion. Female gender and young age had a positive impact. Preoperative radiography and the postsurgical interval are poorly predictive for the progression of osteoarthrosis.
