Hipokrat 2000 total knee arthroplasty in gonarthrosis: Midterm follow-up results

Abstract

The aim of this study is to assess the mid-term results of Hipokrat 2000 total knee arthroplasty applications in gonarthrosis cases. Between February 2000 and January 2004 in Department of Orthopedics, Medical Faculty, Ondokuz Mayis University, Hipokrat 2000 total knee arthroplasty was applied to 68 knees (31 right, 37 left) of total 54 patients (49 female, 5 male) with the diagnosis of gonarthrosis. The average age of the patients at the time of surgery was 63.5 (distribution 49-80). Etiological reason was determined to be primary osteoarthritis in 49 patients and rheumatoid arthritis in 5 patients. Patellar component was used in 63 of the cases. The cases were assessed before and after the surgery in accordance with clinical and radiological evaluation and scoring system of the Knee Society. The average follow-up period was 52.6 months (distribution 28-76 months). In accordance with clinical evaluation system of the Knee Society, in 61 of the 68 knees (89.7%) the result was good or excellent, in 5 patients (7.3%) the result was fair, in 2 patients (2.9%) the result was poor. An increase of average 56.7 degrees in knee scores and average 52.1 degrees in function scores was detected. Average 37.5 degrees of increase was detected in the range of movement in comparison to pre-operation. The average alignment angle in the knees was found to be 4.68 degrees valgus. As complications; in one patient patellar subluxation, in one patient superfi cial infection, in one patient deep infection and in one patient deep vein thrombosis were seen. When studies carried out with other semi constrained, posterior cruciate ligament retaining surface replacement prosthesis brands in literature were reviewed; the fact that the clinical and radiological results of Hipokrat 2000 total knee arthroplasty are good shows that it is an appropriate prosthesis for advanced gonarthrosis cases. © 2012 OMU All rights reserved.
