In a randomized, single-blind study, the efficacy of single-dose cefotaxime was compared with multiple dose cefoxitin in genitourinary surgery prophylaxis. Patients received either 1.0 g cefotaxime before surgery; or 2.0 g cefoxitin pre-operatively and every 8 h for no more than 24 h post-operatively. Of the evaluable patients receiving cefotaxime 3 of 35 (8.6%) became infected post-operatively, compared to 12 of 37 (32.4%) patients receiving cefoxitin (P less than 0.01). It is concluded that single-dose genitourinary surgical prophylaxis with cefotaxime may be more effective than a longer dosing schedule with cefoxitin in the prevention of post-operative urinary tract infections, and that a single-dose regimen may represent significant cost containment advantages for hospitals.
PurposeThe aim was to assess the consequences of quadriceps tendon (QT) harvest on knee extensor strength after anterior cruciate ligament reconstruction (ACL-R) compared to hamstring tendon (HT) autograft. Secondary objectives were to evaluate flexor strength recovery and search for correlation between strength status and functional outcome. Methods This a retrospective cohort of 44 patients who underwent ACL-R using either QT (25) or HT (19). Median age was 31.1 years. We assessed thigh muscle strength thanks to concentric iso kinetic evaluation (peak torque) at 60°.s −1 , 180°.s −1 , 240°.s −1 and eccentric at 30°.s −1 , 7 months on average after surgery. Muscle strength values were compared to the uninjured leg in order to calculate a percentage of deficit as well as unilateral hamstring/quadriceps (H/Q) ratios. KOOS score was obtained at a mean follow-up of 18 months. Results Extensor strength deficit (concentric 60°.s −1 ) was one average 33.1% in the QT group and 28.2% in the HT group (p = 0.42). Difference of flexor strength deficit (concentric 60°.s −1 ) was close to be significant with 5% and 12% of deficit in the QT and HT group, respectively (p = 0.1), and statistically significant for high angular velocity (14% versus 3% at 240°. s −1 , p = 0.04). H/Q ratios were comparable in both groups ranging from 0.62 to 0.78. Quadriceps muscle strength deficit was negatively correlated with the KOOS score (Pearson coefficient = −0.4; p = 0. 005). Conclusion QT autograft harvest does not yield significant quadriceps muscle weakness after ACL-R, which appear to be a pejorative factor for functional outcome. Level of evidence IV, Retrospective study.
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.
