[Results of arthrodesis after knee prosthesis infection. Special reference to quality of life]

Abstract

Aim of the study: In case of extensive bone loss arthrodesis can be more favourable than one or two stage revisions with new arthroplasties after infected implants.

Material and methods: 19 patients with arthrodesis of the knee joint because of infected arthroplasty were clinical-radiological examined after 5.2 years. The quality of life was measured with the SF-36 score. The average age at the arthroplasty implantation was 63.8 years. 5 patients had constrained prostheses, 14 bicondylar sledge prostheses.

Discussion: The average results in health orientated life quality of patients with arthrodesis in case of infected arthroplasty were lower than in control groups but singular aspects scored higher. After the arthrodesis some patients increased their levels compared to the period with arthroplasty.

Clinical relevance: The fear of loss of quality after arthrodesis of the knee joint can not be supported. Some results were not better with arthroplasty or without an operation.
