OBJECTIVE: To identify prognostic factors of postoperative functional outcomes. METHODS: Retrospective case series evaluating patients undergoing rotator cuff repair, analyzed by the UCLA score (pre and 12-month postoperative) and Magnetic Resonance Imaging (preoperative). Patients' intrinsic variables related to the injury and intervention were evaluated. Multivariate linear regression analysis was performed to determine variables impact on postoperative functional assessment. RESULTS: 131 patients were included. The mean UCLA score increased from 13.17 ± 3.77 to 28.73 ± 6.09 (p<0,001). We obtained 65.7% of good and excellent results. Age (r= 0.232, p= 0.004) and reparability of posterosuperior injuries (r= 0.151, p= 0.043) correlated with the functional assessment at 12 months. After multivariate linear regression analysis, only age was associated (p = 0.008). CONCLUSIONS: The surgical treatment of rotator cuff tears lead to good and excellent results in 65.6% of patients. Age was an independent predictor factor with better clinical outcomes by UCLA score in older patients. Level of Evidence IV, Case Series.
ObjectivesDetermine the stability of tibial and femoral components of 20 cementless knee
arthroplasties with rotating platform.MethodsThe 20 patients (20 knees) underwent an analysis of dynamic radiographs with an image
amplifier and maneuvers of varus and valgus which were compared to static frontal and
lateral radiographs of the knees and analyzed by two experienced surgeons in a
double-blind way.ResultsWe could observe in this study that both methods showed very similar results for the
stability of the tibial and femoral components (p<0.001) using the Kappa method
for comparison.ConclusionThe tibial component was more unstable in relation to the femoral component in both
static and dynamic studies. Level of Evidence IV, Case
Series.
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.
