Abstract：Objective To explore the risk factors for re-tear in osteoporosis patients with rotator cuff injuries after arthroscopic repair surgery,and to construct a nomogram to predict its risk.Methods A total of 123 osteoporosis patients with rotator cuff injuries who underwent arthroscopic repair surgery from March 2020 to April 2023 were included.According to the 1-year occurrence of re-tear after surgery,they were divided into the occurrence group(36 cases)and non-occurrence group(87 cases).The risk factors for re-tear occurrence in patients were analyzed,and a nomogram was constructed.Results After preliminary comparison of the general data between the occurrence group and the non-occurrence group,a regression model was constructed.The results showed that the history of diabetes,smoking,fat infiltration,tear size,rotator cuff retraction,preoperative low levels of serum 25(OH)D3,and surgical single row repair were the risk factors for postoperative re-tear in osteoporosis patients with rotator cuff injury(OR>1,P<0.05).A nomogram was constructed for parallel internal validation,and the internal calibration curve of the model fits well with the ideal curve,with an area under the curve(AUC)of 0.895(95%CI:0.835-0.955),indicating good prediction accuracy.Conclusion History of diabetes,smoking,fat infiltration,tear size,rotator cuff retraction,low levels of serum 25(OH)D3 before surgery,and single row repair surgery are all risk factors for postoperative rotator cuff tear in osteoporosis patients with rotator cuff injury.The nomogram can be used to predict the risk of re-tear.
