Evaluation of the benefit-risk of suture anchor repair of triangular ligament injury in open reduction and internal fixation of ankle fracture based on multi-criteria decision model
Objective To evaluate the benefit-risk of suture anchor to repair the third degree injury of the triangular ligament in the open reduction and internal fixation(ORIF)of ankle fracture for repairing based on the multi-criteria decision model.Methods From July 2020 to July 2022,120 patients with ankle fracture complicated with triangular ligament injury were treated in our hospital,60 patients were treated with suture and anchor repair combined with ORIF as the observation group,and 60 patients treated with ORIF alone as the control group.The clinical data of the two groups were compared,a multi-criteria decision-making model was established,and its stability was evaluated.Results The length of stay,fracture healing time,total effective rate and incidence of postoperative complications in the observation group were(15.72±2.28)d,(11.39±2.46)weeks,96.67%(58/60)and 6.67%(4/60),respectively,while those in the control group were(18.65±2.38)d,(13.62±2.74)weeks,75.00%(45/60)and 21.67%(13/60),respectively;there were significant differences between the two groups(P<0.05).Internal ankle space,talus inclination angle,visual analogue score(VAS),American Association of Orthopedic Foot and Ankle(AOFAS)score β Collagen degradation products(β-CTX),BGP,and BALP before treatment in the observation group were(6.89±1.21)mm,(12.69±3.08)°,(6.72±1.59),(56.85±8.14),(0.88±0.25)μg/L,(3.46±1.01)μg/L and(79.49±9.52)U/L,respectively.After the treatment,the indicators above were(2.12±0.95)mm,(4.36±1.11)°,(1.08±0.25),(85.96±9.28),(0.29±0.14)μg/L,(7.50±1.39)μg/L and(140.82±15.79)U/L,respectively.In the control group,the medial malleolus space,talus tilt angle,VAS score,AOFAS score,β-CTX,BGP and BALP before treatment were(6.82±1.18)mm,(12.54±3.21)°,(6.65±1.64),(57.42±7.67),(0.85±0.21)μg/L,(3.61±0.92)μg/L and(80.73±10.64)U/L,respectively.After treatment,the indicators above were(3.72±1.03)mm,(5.72±1.39)°,(2.31±0.32),(78.36±9.06),(0.51±0.18)μg/L,(6.11±1.28)μg/L and(109.25±13.61)U/L,respectively There was no significant difference in medial malleolus space,talus tilt angle,VAS score,AOFAS score,β-CTX,BGP and BALP between the two groups before treatment(P>0.05).After the treatment,the indexes of the two groups mentioned above were significantly improved as compared with those before treatment(P<0.05),and the improvement effect of each index in the observation group was significantly better than that in the control group(P<0.05).The benefit values of the control group and the observation group were 63 and 77,the risk values were 29 and 55,and the benefit-risk values were 46 and 66,respectively.The stability of the model was good.Conclusions The application of suture anchor to repair the third degree injury of triangular ligament can significantly improve the clinical benefit and reduce the risk of postoperative complications in the treatment of ankle fracture with ORIF.
