| Objective:This study was to compare the effects of ACL reconstruction with allogeneic tendon and autologous hamstring tendon,and provide a reliable grafting protocol for future ACL reconstruction of the knee joint.Method:The data of 46 patients who underwent ACL reconstruction surgery from May 2016 to May 2018 in the First Affiliated Hospital of Hunan Normal University and met the inclusion and exclusion criteria were analyzed.The selected cases were then divided into allogeneic tendon(group A)and autologous hamstring tendon(group B).The duration of surgery,the time of wound healing,the pain of knee incision,and the VAS score of knee joint were selected after surgery.The two groups of patients were studied before and after surgery.The Lysholm score,IKDC score and Tegner score were used in both groups A and B to evaluate the knee function before and after surgery.The stability of the knee joint was compared by ADT test and Lachman test.The data were carefully proofed,the database was established,and the final statistics and analysis were performed using SPSS20.0 statistical software.The measurement data were analyzed by sample t test,and the count data were analyzed by X2 test,P<0.05.The difference was statistically significant..Result:For 46 patients with postoperative observation,the function of knee joints in group A and group B was significantly better than that before operation.The length of operation was compared: group A:(51.26±10.11),group B:(78.49±11.16)The difference was statistically significant(P < 0.05).Wound healing time: A group(14.20±4.16)days,group B(12.82±5.36)days,the difference was statistically significant(P<0.05).The overall VAS score of the knee joint(see Appendix): group A(2.63 ± 0.53),group B(4.48 ± 0.42),the difference was statistically significant(P <0.05).Tegner score(see appendix): Group A(3.48±0.57),group B(3.51±0.43),and group A(4.26±1.06),group B(4.32±0.86),group B(4.32±0.86)There were no significant differences between the two groups(7.52±1.21)and B(7.43±0.42)at 9 months after operation(P>0.05).Lysholm's score(see appendix): Group A(52.40±1.52)and group B(52.61±1.41)were reviewed 3 months after operation.Group A(84.52±1.43)was reviewed 6 months after operation,and group B(84.72±1.35)There were no significant differences between the A group(95.48±1.23)and the B group(95.12±1.02)at 9 months after operation(P>0.05).IKDC score(see appendix): 95.83% of the 24 patients in group A(23 cases)were basically normal at 9 months postoperatively,and 95.45% of the 22 patients in group B(21 cases)were basically normal,and the difference was not statistical.Academic significance(P>0.05).Postoperative positive ADT and Lachman results were not statistically significant.(P>0.05)Conclusion:The use of allogeneic tendons and autologous hamstring tendons can provide reliable results in ACL reconstruction,restoring the function and stability of the knee joint.The use of allogeneic sources of tendon surgery procedures is less,the patient's knee incision and knee joint pain is lighter,the wound healing faster after the use of autologous hamstring tendon. |
