Abstract
Follow-up study was made on results of artroplasty using interposing membranes performed on 4 hip and 6 knee joints (tuberculosis 6, pyogenic infection 3 and trauma 1) during 1957 to 1971. Age at surgery was 19 to 39, and an average of 20 years have elapsed since.
Although X-ray showed sclerosis and absorption of articular surface, relief from pain, good stability, mobility and muscular power were restored in 7 out of 10. Pyogenic infection cases showed results inferior to those of other causes. Despite progress in artificial material, this procedure cannot be neglected from the biological viewpoint.
