This study suggests that waiting time for hip fracture surgery more than two days was not associated with higher complication or mortality rate if waiting was to stabilize patients with active comorbidities at admission, compared to stable patients at admission with early surgery. Although early surgery within two days from admission is desirable for stable patients at admission, in patients with complex comorbidities, the surgery should be performed once they are optimized. However, the patients with delayed surgery for organizational reasons had a significant higher rate of post-operative complications and one year mortality compared to the other two groups.

The superiority of one design over the other was not found. Both designs can be used expecting long-term successful outcomes and high survival. The choice of the design depended on the status of the posterior cruciate ligament and surgeon preference.

Purpose To determine cutof values for the Knee Society Scores (KSS) indicative of a categorical scale of medium-term outcomes. Methods One hundred and ifty-ive patients who underwent primary cruciate-retaining TKA with a patellar button for osteoarthritis at a single-centre were assessed prospectively by the KSS and short-form Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) simultaneously at the 3-year follow-up. A validated categorization of the WOMAC score was used as a standard. The area under the curve (AUC) of receiver-operating characteristic (ROC) was used to assess the discriminative analysis accuracy of the, and the Youden index estimated the optimal cutof point. Results For the KSS-knee score, the cutof for an excellent outcome was 90.3 (AUC 0.75, 95% CI 0.71-0.78), 76.6 (AUC 76.6, 95% CI 0.70-076) for good, 64.8 (AUC 0.76, 95% CI 0.72-0.79) for fair, and < 64.8 (AUC 0.69, 95% CI 0.67-0.73) for poor. For the KSS-function score, the cutof values were 85.2 (AUC 0.71, 95% CI 0.69-0.75), 73.1 (AUC 0.72, 95% CI, 0.70-0.76), 55.7 (AUC 0.70, 95% CI 0.71-0.74), and < 55.7 (AUC 0.68, 95% CI 0.66-0.72), respectively. Conclusion A KSS-knee score ≥ of 90 was considered an excellent outcome, 77 good, 65 fair, and < 65 poor. For the KSSfunction, those values are 85, 73, 56 and < 56, respectively. The treatment outcome's judgement may be clearer for the surgeon concerning a particular patient when using cutof values for the scoring system employed, such as those determined in the present study.
