Clinical Observation of the Effect of Surgical Treatment for Anterior Cru-ciate Ligament Injury with Medial Collateral Ligament Rupture in StagesⅠ and Ⅱ
Objective To compare the effects of surgical treatment for anterior cruciate ligament(ACL)injuries with medial collateral ligament(MCL)rupture in stageⅠand stageⅡ.Methods A total of 89 patients with ACL injury accom-panied by MCL rupture who were admitted from September 2021 to October 2023 were selected and divided into stageⅠgroup(n=45)and stageⅡgroup(n=44)according to the timing of surgery.Patients in the stageⅠgroup underwent arthroscop-ic reconstruction of the ACL with autologous hamstring tendons and fixation of the MCL avulsion point.Patients in the stageⅡgroup underwent immobilization for 4-6 weeks before undergoing reconstruction of the ACL with autologous hamstring tendons.The excellent and good rate of surgery in the two groups was observed,and the knee joint function[International Knee Docu-mentation Committee(IKDC),Lysholm,Tegner scores]before and after surgery,the results of the Lachman test,the results of the axial displacement test,the degree of opening of the medial gap under stress,the knee flexion function of the affected side and the healthy side,balance and gait during walking were compared.The occurrence of postoperative complications in the two groups was recorded.Results The excellent and good rate of the stageⅡgroup at 12 months after surgery[95.45%(42/44)]was higher than that of the stage Ⅰ group[80.00%(36/45)](P＜0.05).The IKDC,Lysholm,and Tegner scores in the stage Ⅱ group were higher than those in the stageⅠgroup at 6 and 12 months after surgery,and the proportion of patients with Lachman test score of 0 and axial displacement test score of-0 was higher than that in the stageⅠgroup(P＜0.05).The proportion of patients with a range of motion(ROM)of 0-5 mm in the medial gap at the stress position at 6 and 12 months after surgery in the StageⅡgroup was higher than that in the StageⅠgroup,and the proportion of patients with a difference of 0° between the affected and unaffected sides in knee flexion was higher than that in the Stage Ⅰ group(P＜0.05).The step length,single leg support period,maximum pressure on the forefoot,and maximum pressure on the heel on the affected side in the stageⅡgroup were higher than those in the stageⅠgroup,while the toe out angle was lower than that in the stage Ⅰ group(P＜0.05).There was no significant difference in the total incidence of complications between the two groups(P＞0.05).Conclusion The surgical treatment of patients with ACL injury accompanied by MCL rupture in stageⅡis effective,improving joint stability,knee function,and gait balance,with good safety.
