The safety of tissue engineered cartilage constructed for reconstruction is preliminarily confirmed, but the effectiveness still needs further verification.

To analyze the risk factors for postoperative mortality of the elderly patients with femoral neck fracture undergoing hemiarthroplasty. Patients who underwent hemiarthroplasty for femoral neck fractures between January 2011 and December 2015 were enrolled as object. One hundred and nine patients who met the selection criteria were included in the study, and the clinical data were collected, including gender, age, time from admission to surgery, comorbidities, and preoperative hemoglobin level and nutritional status. Univariate analysis and Cox proportional hazard regression model were used to screen the risk factors for postoperative mortality. The 1-year and 2-year mortalities were 6.4% (7/109) and 17.4% (19/109), respectively. Univariate analysis showed that the age, preoperative hemoglobin level and nutritional status were the influencing factors of postoperative mortality in the elderly patients with femoral neck fractures treated with hemiarthroplasty ( <0.05). Multivariate analysis showed that the age≥80 years and malnutrition were the independent risk factors for postoperative mortality ( <0.05). To improve the clinical outcomes, perioperative risk should be comprehensively evaluated by multidisciplinary and perioperative management should be strengthened in the elderly patients with femoral neck fracture, especially those with advanced age and malnutrition, for the high postoperative mortality. To improve the clinical outcomes, perioperative risk should be comprehensively evaluated by multidisciplinary and perioperative management should be st
