Suleyman Demirel University TIP FACULTY JOURNAL: December 2007; 14(4) Moving polyethylene inserted and fixed polyethylene inserted knee prothesis assessment of the mid-term results of patients we apply Tolga Atay, Osman Gazi Aksoy, Nevres Hürriyet Aydoğan Suleyman Demirel University Medical Faculty, Orthopedics and Traumatology Anabolic Department. In recent years, as a result of developments recorded in the prothesis design and surgical techniques, successful results have been achieved in knee artroplastics. As a result of these developments, different protez designs have emerged. Both types of moving and fixed ingested knee proteases can result in successful clinical results. In our study, from February 2001 to March 2003, we assessed the median-term results of these cases by applying a mobil and fixed injected knee protection to 54 patients from 53 patients. The clinical assessments of our patients in the preoperative and postoperative period were performed according to the assessment system recommended by the Knee Society (1-3). In the preoperative assessment, there was no significant difference between the average knee and function scores per group. (Mann-Whitney U test, p>0.05). When we compared the postoperative results of patients, there was no significant difference between the two groups, but the highest scores of the knee and function of the moving inserted knee protezes were found. (Mann-Whitney U test, p>0.05). In the postoperative radiological assessment, we did not find any relief findings in any of our patients we applied active and fixed polyethylene inserted knee prothesis. As a result, although there is no statistically meaningful difference between the clinical results of both knee proteins in the mid-term period, we have found that the clinical results of moving inserted knee proteins are better. Keywords: osteoartritis; total knee protection; moving insert; fixed insert Abstract: The evaluation of the midterm results of the patients applied knee prosthesis with polyethylene mobile bearing and fixed bearing insert Recent years there have been successful results on knee arthroplasty because there have been improvements on designs of the prosthesis and surgical techniques. Because of these improvements different prosthesis designs have appeared. Successful results have been able to be achieved with the knee prosthesis with both mobile bearing and fixed bearing insert. In our study, we evaluated the mid-term results of 53 patients, whose 54 knees, we applied knee prosthesis with mobile bearing and fixed bearing insert between February 2001 and March 2003. In the preoperative and postoperative periods the clinical evaluations of our patients were done according to the evaluation system suggested by Knee Society. In the preoperative evaluation, there were no dramatic differences between the average scores of the knee and function according to the groups (Mann-Whitney U test, p>0.05). When we compared the postoperative results of the patients, again there were no dramatic differences between the two groups but it was found that the scores of knee and functions of knee prosthesis with mobile bearing insert were high (Mann-Whitney U test, p>0.05). In the radiological evaluation of the postoperative period we did not see any loose symptoms on any of our patients in both groups. In conclusion, statistically there was not a dramatic difference between the mid-term clinical results of both knee prosthesis but according to our assessment the clinical results of mobile bearing inserted knee prosthesis was better. Key words: osteoarthritis; total knee arthroplasty; mobile bearing insert; fixed bearing insert
