REVISION ARTHROPLASTY FOLLOWING THE ASEPTIC AND SEPTIC LOOSENING WITH MODULAR ENDOPROTHESIS

AIM: The aim of this study is to analyze results after implantation of revision total knee arthroplasties, endoprsthesis model Kinemax Plus Superstabilazer. MATERIAL AND METHODS: Between 2000 and 2005 we implanted 45 modular revision knee endoprsthesis model Kinemax Plus Superstabilazer at 44 patients. The mean age was 69.22 (57-85) years. The indications for revision knee arhroplasty included pain and aseptic instability in 39 knees. Septic instability of the primary knee endoprosthesis was performed in 6 patients, treated with two-stage revision arthroplasty. Follow-up was 19.27 (6-54) months. RESULTS: The mean surgical time was 132 (85-165) min. and blood loss 1566 (620-4000) ml. At 3 knees we performed wound revision because of the haematoma. At 5 patients we had deep infection treated with by debridement, liquid drainage and antibiotics. At two of them we removed revision endoprosthesis because infection reccurense and knee arthrodesis performed successfully. One patient had patellar luxation and another had patellar fracture, both treated surgically. One patient needed tibial insert replacement because of knee instability. We lost from follow-up 10 (22.2%) patients. From 35 knees which were followed up, 33 revision knee arthroplasty survive. Next 2 (5.71%) felt because deep infection, followed by arthrodesis. Of this 33 knees no clinical signs of instability of revision endoprosthesis were found during follow-up period, but at 4 (12.12%) knees we found at X-ray radiolucency more then 1mm. CONCLUSION: General conclusion is that modular type of the revision endoprosthesis allows solving main problems of complex revision arthroplasty of the knee joint.
