Patient-reported quality of life and pain after PWB in surgically treated tibial plateau fractures 75 Time from surgery till full weight bearing and the total number and type of postoperative complications were collected from the electronic medical records. A postoperative complication was defined as a composite end-point comprising any complication, related to the fracture, that occurred during the aftercare regimen, these were recorded as either present or not present, along with the type of complications. The medical ethics committee of Zuyderland Medical Center, Heerlen, the Netherlands approved this study and informed consent was given by all patients. Statistical analysis Statistical analysis was performed with IBM SPSS Statistics, Version 23.0, Armonk, New York. Descriptive statistics were used to describe the demographic data and baseline characteristics of the entire population. Independent samples t-tests were used for normally distributed continuous data and chi-squared tests for categorical variables. Results are presented as either mean ± standard deviation (SD) or as frequencies and percentages. In case of non-parametric data the median with the interquartile range (IQR) are described. Binary logistic regression was performed to assess independent predictors of late full weight bearing (>12 weeks) throughout both PWB and RWB ŐƌŽƵƉƐ͘ dŚĞ ůĞǀĞů ŽĨ ƐƚĂƚŝƐƚŝĐĂů ƐŝŐŶŝĨŝĐĂŶĐĞ ǁĂƐ ƐĞƚ Ăƚ ɲсϬ͘Ϭϱ͘ Results Baseline characteristics This cohort study included 91 patients, 31 of whom were in the PWB group and 60 in the RWB group. Characteristics of patients in the PWB group and RWB group are presented in Table 6.1. Patients in the PWB group were significantly more likely to have a more complex fracture type (Schatzker fracture type (IV-VI)22Ϳ ;ƉсϬ͘ϬϰͿ Ănd more concomitant fractures than those in the RWB group (p<0.01). No differences in age or gender were found between the two groups. Furthermore, no differences were found in surgical procedures between the two groups.
