Purpose. To compare the measured resection technique and the gap balancing technique for correction of the femoral rotational alignment. Methods. 57 women and 6 men (mean age, 70 years) with end-stage osteoarthritis and ±15° malalignment and ±10° flexion contracture of the knee underwent primary total knee arthroplasty through the medial approach using the measured resection technique (n=34) or the gap balancing technique (n=29). Femoral rotational alignment was evaluated before and 7 days after surgery using computed tomography by referencing the 2 posterior condyles to the transepicondylar axis. Results. The 2 groups did not differ significantly in terms of correction of the femoral rotational alignment (3.4°±1.4° vs. 3.5°±3.1°, p=0.817). Conclusion. The measured resection and the gap balancing techniques achieved comparable correction of femoral rotational alignment.

Background: Fragility-related pertrochanteric fractures have become a significant public health concern, with a rising incidence attributed to the expanding elderly demographic. Assessing patient-reported health-related quality of life (HRQoL), mortality, and factors correlated with them serves as a crucial metric in evaluating the effectiveness of hip fracture surgery. Methods: In a single-center retrospective study, 259 patients underwent surgical treatment with a cephalomedullary nail, with a mean follow-up of 21.7 months. Health-related quality of life (HRQoL) was assessed using SF-12 (12-item Short Form) and EQ-5D (EuroQoL-5 Dimensions) questionnaires. Mobility status was measured by the Crude Mobility Index (CMI). Surveys were administered during hospitalization and six months postoperatively. Statistical analysis involved descriptive statistics, non-parametric controls (Kendall, Mann-Whitney, and Wilcoxon), and Spearman correlation and logistic regression analysis, which were conducted using IBM SPSS version 28. Results: A statistically significant decrease was observed in the mean EQ-5D and SF-12 scores at 6 months post-op compared to the pre-fracture status. The ASA (American Society of Anaesthesiologists) score showed a significant correlation with the decrease in HRQoL measured by the SF-12 questionnaire. The 30-day post-operative mortality rate was 9.3%, increasing to 32.4% at 1 year. Notably, the 30-day mortality significantly rose during the pandemic era (5.0% vs. 12.0%; p = 0.003). Conclusions: Pertrochanteric hip fractures cause a lasting decline in quality of life. Annual mortality is high, and further investigations are needed to formulate policies that prevent hip fractures and reduce mortality rates.
