“…24, 25 Ecker and colleagues 24 reported that there was no statistically significant correlation between the occurrence of thin radiolucent lines in any location and the eventual postoperative clinical result and that radiolucent lines greater than 2 mm were associated with poor results. In our study, there were no radiolucent lines around patellar components, and we observed radiolucent lines in 12.8% of femoral components and 24% of tibial components.…”

Background: Total knee arthroplasty (TKA) using a cemented technique has been recommended in patients with rheumatoid arthritis owing to the initial stability of the fixation and long-term durability of the components; however, similar long-term follow-up results have been reported in patients who have undergone cementless TKA. The purpose of this study was to evaluate the radiologic and clinical outcomes of cementless TKA in patients with rheumatoid arthritis. Methods:We enrolled patients undergoing cementless TKA from March 1990 to February 2000. Clinical and radiologic evaluations were performed using the Knee Society clinical rating system and radiographic evaluation and scoring system. Results:We included the cases of 112 patients who underwent 179 cementless TKA procedures in our analysis. Their mean age was 62.3 years, and the mean follow-up period was 10.1 years. The final survival rate was 0.968 at the 15.5-year follow-up. Regarding radiologic results after surgery, the mean total valgus angle was 6.7°, the mean femoral flexion angle was 97.5° and the mean tibial angle was 89.2° on the anteroposterior radiographs. On the lateral films, the mean femoral flexion angle was 1.6° and the mean tibial angle was 89.2°. At the last follow-up, the mean total valgus angle was 6.5°, the mean femoral flexion angle was 97.4° and the mean tibial angle was 89.1°, as seen on the anteroposterior view. On the lateral views, the mean femoral flexion angle was 1.4° and the mean tibial angle was 89.0°. Regarding the clinical outcome, the mean knee score and function score on the Knee Society clinical rating system were also enhanced from 47.5 and 43.6, respectively, before the operation to 91.2 and 82.3, respectively, at the last follow-up. Conclusion:On radiologic and clinical follow-up of cementless TKA for patients with rheumatoid arthritis, there were no serious complications, and the results of the operation were satisfactory with improvement in range of motion and clinical symptoms.Contexte : On a recommandé l'arthroplastie totale du genou (ATG) fixée par ciment orthopédique chez les patients souffrant de polyarthrite rhumatoïde, en raison de la stabilité initiale de la fixation et de la longue durabilité des composantes. Or, des résultats similaires ont été enregistrés au suivi à long terme chez des patients qui ont subi une ATG non cimentée. Cette étude avait pour but d'évaluer l'issue radiologique et clinique de l'ATG non cimentée chez des patients souffrant de polyarthrite rhumatoïde.

In 1988 we did develop an EDP-System for data collection of daily routine documentation, which allows on the one hand a complete registration and on the other hand only offers entire and plausible data because of the logical program structure. The registered data are saved in a data bank structure as well as in report form for routine documentation. The substitution of routine documentation by such a system essentially depends on the content of interrogation which has to reflect the user's individual indication and operative technique. First doubts about reflection of the high variation of the individual operative technique could be disproved with help of the evaluation of this system of documentation. None of the 200 registered cases had to be documented without the help of the standardized system. The use in a prospective multicenter study for endoprosthesis of the knee was the starting point of the evaluation for the system's efficiency and acceptance. It had been analyzed the expressiveness of the study's documentation. As there was no standard in free dictated operation records the information content seemed to be reduced and with regard to scientific aspects unqualified. The analysis of the EDP-system especially checked three aspects: the general suitability to represent medical facts by standardized evaluation as well as the user's and patient's acceptance. All in all this system is an instrument for standardized daily routine documentation in a clinic which seems able to establish a quality management because of the high data quality, the differentiated registrations of multiple parameters and timeneutral application.
