Effect analysis of femoral and tibial tunnel technique combined with U-shape suture in treatment of posterior root tear of medial meniscus with posterior cruciate ligament rupture
Objective To investigate the efficacy and safety of femoral and tibial tunnel technique combined with U-suture in the treatment of posterior root tear of medial meniscus with posterior cruciate ligament rupture.Methods Totally 50 patients with meniscus posteri-or root tear and posterior cruciate ligament rupture admitted to our hospital from January 2020 to January 2022 were divided into two groups.The control group was treated with arthroscopic meniscus medial and external suture and posterior cruciate ligament B-T-B repair technology,and the observation group was treated with femoral and tibial tunnel technology+U-shaped suture.The operation related indicators and healing rate were compared.Preoperative and postoperative evaluation of knee joint function,and before the surgery,4 weeks after surgery and postop-erative knee stability assessment when 4 months;The degree of limb pain was evaluated before operation and 48 hours after operation.The changes of self-care ability were compared before operation and at the end of follow-up,and the incidence of complications was counted.Results observation group operation time,postoperative weight-bearing walking time for the first time are shorter than that of the control group,and postoperative Lysholm knee score,the knee society score(AKS)were higher than that of the control group(P＜0.05);At 4 months after surgery,the positive rate of reverse axis shift test,posterior drawer test and grinding test were significantly lower than at 4 weeks after sur-gery,and the difference was statistically significant(P＜0.05),but the difference between the 2 groups was not significant(P＞0.05),The nu-merical rating scale(NRS)score of the observation group was significantly lower than that of the control group,and the score of activities of daily living(ADL)was higher than that of the control group.Compared of complicationsthe two groups have no difference(P＞0.05).Conclusion Femur and tibial tunnel combined with U-shape suture is feasible for patients with medial meniscus posterior root tear and poste-rior cruciate ligament tear,which can not only guarantee the repair effect,but also reduce the surgical injury,shorten the operation time,re-lieve postoperative pain,and more conducive to the functional rehabilitation of knee joint.
