Long-term results after a triple arthrodesis of the hindfoot: function and satisfaction in 36 patients.
The long-term functional results of a triple arthrodesis of the hindfoot are not well known. In this retrospective cohort study we therefore investigated pain, function and alignment of the tibiotalar joint, patient satisfaction with the procedure and the prevalence of osteoarthritis (OA) of the tibiotalar joint after a median follow-up of six years. We also aimed to investigate whether there are patient and surgical characteristics associated with the outcome. Patients who underwent a triple arthrodesis for OA between January 1992 and July 2002 were invited to participate. A clinical examination was performed, the Ankle-Hindfoot Scale was completed, and radiographs were taken. Patient characteristics (e.g., age, gender and the indication for operation) and surgical characteristics (e.g., fixation material and use of bone graft) were collected. Sixty-one percent (22 patients) of the patients had a good total score on the Ankle-Hindfoot Scale. Nineteen patients (53%) were satisfied with the result of the operation and 47% of the patients had radiographic OA of the tibiotalar joint. In a univariate regression analysis, male gender and the score on the Ankle-Hindfoot Scale were significantly associated with radiographic OA. Patient satisfaction was significantly associated with a higher score on the Ankle-Hindfoot Scale and better dorsi-flexion of the ankle. Our study shows that 61% of the procedures in 36 patients with a triple arthrodesis for OA had a good score on the Ankle-Hindfoot Scale. Radiographic OA of the ankle was present in 47% of the cases and was not related to patient satisfaction. No patient characteristics or surgical characteristics were associated with the score on the Ankle-Hindfoot Scale.
