This study has investigated the efficiency and reliability of articulating cement spacer (Synicem, Synimed) in 17 patients with infected Total knee arthroplasty (TKA), that underwent primary TKA between December 2003 and February 2006. In this study, 16 out of 17 patients (94.1%) achieved infection eradication upon treatment. However, in the last follow-up three patients (17.6%) required a reoperation. Of these two patients (11.7%) developed infection within a mean interval of 1-year. The pre-operative mean joint motion ranges of patients was 58° and in the presence of spacer between two stages was 69° and post last follow-up examination, 85°. Advantages to the spacer used in this study (Synicem, Synimed) included: 1) Preserved joint space and extremity length with increase in range of joint motion, prevent adhesion of spacer to bone hence causing no bone loss and facilitates in reimplantation surgery. 2) Allowing for partial weight-bearing thus preventing osteoporosis development and increasing the quality of patient’s life between two stages. 3) Protecting extensor mechanism and lateral ligaments. 4) Facilitating the release of antibiotic into the infected area.
