Between December 1996 and December 2002, we treated 79 patients with arthroscopy-assisted anterior cruciate ligament (ACL) reconstructions. In 53 patients we used autografts and in 26 patients allografts. Patients were followed up for 38 (12-72) months. The two groups did not differ in preoperative sport activity level. The postoperative Lysholm score was 89.9±8
Background: The aim of the present study was to establish an in vitro microbiologic monitoring system which measures the dynamics of antibiotic release from acrylic bone cement and its antibacterial efficacy. Methods: Palacos R® and Orthofix R® cements containing gentamicin sulfate were tested. The in vitro elution dynamics was analyzed by plate diffusion method during a 1-year period after mixing. High but rapidly decreasing antibiotic levels were detected within the 1st week, resulting in an almost steadily low concentration by the end of the 1st month. After 1 year, it was still possible to demonstrate the inhibitory effect of the drug from both cements. Comparison of the time-related release between the antibiotics failed to find any statistically significant differences. Conclusion: The method described is a useful and reproducible technique for the in vitro measurement of the inhibitory activity of antibiotic released from bone cements.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
