The objective of the presented work was to evaluate the results of revised replacements of the hip joint using non-cemented CLS Spotorno sockets and cemented polyethylene sockets of 1992 - 1993. The baseline situation was identical: an aseptically loosened polyethylene socket, intact pillars and preserved acetabular margins. In the group of CLS Spotorno sockets there were 56 patients, 52 were evaluated after an average period of 42 months following revision. In the CLS Spotorno group the mean Harris hip score was at the end of the study 84.6 points. The authors recorded complete osteointegration of the socket in 45 instances. There were 7 sockets with radiolucent margins. In the group of cemented polyethylene sockets the mean Harris hip score was 74.3 points. The total number of radiolucent margins was 24. Three patients had already a second surgical revision, five patients had symptomatic and six asymptomatic loosening of the socket. Complete osteointegration of the socket was recorded in 28 patients. The cumulative probability of clinical non-failure of the cemented polyethylene socket after 43 months was 79.34 %. The cumulative probability of non-failure of the non-cemented socket CLS Spotorno after 42 months was 94.44 %. Key words: alloplasty of the hip joint, revised replacements of the socket.
