Abstract:
Objective:To investigate the clinical effectiveness of autologous hamstring tendon reconstruction with preserved synovial sheath combined with remnant suture in the treatment of anterior cruciate ligament (ACL) tears.Methods:A retrospective study was conducted to analyze the clinical data of 38 patients with ACL tear who had been admitted to Department of Sports Medicine, The Fourth Hospital of Wuhan from January 2016 to July 2020. There were 30 males and 8 females, with an age of (25.4±7.2) years. By the typing of MRI Sherman tear locations (MSTL) for anterior cruciate ligament, 7 cases were Type I and 31 cases type II. A total of 18 patients underwent single bundle reconstruction of autologous hamstring tendon combined with remnant suture (group A), and the other 20 patients underwent conventional reconstruction to clean the synovial sheath of ACL (group B). The operation time,Tenger scores, Lysholm scores, International Knee Documentation Committee (IKDC) subjective score and side-to-side differences in relaxation at pre- operation, 1 year and 2 years after operation, as well as ACL healing of the affected knee at 2 years after operation, were observed and compared between the 2 groups. The graft synovial coverage was evaluated by secondary arthroscopy in some cases.Results:There was no significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). All patients were followed up for (38.5±8.4) months. No surgical site infection or knee stiffness occurred in the 2 groups after operation, and 2 patients in each group developed intermuscular venous thrombosis at a lower limb. There was no significant difference in operation time between the 2 groups ( P>0.05). There were significant differences in Tenger score [(6.3±1.6) points versus (4.7±1.7) points], Lysholm score [(93.4±4.2) points versus (85.9±4.3) points] and IKDC subjective score [(89.1±2.9) points versus (81.2±2.9) points] between group A and group B at 1 year after operation ( P<0.05), but there was no significant difference in Tenger score, Lysholm score or IKDC subjective score between the 2 groups at 2 years after operation ( P>0.05). There was no significant difference in side-to-side difference in relaxation between the 2 groups at 1 year or 2 years after operation ( P>0.05). MRI evaluation at 2 years after operation showed no recurrent rupture or no sign of impingement between the graft and the intercondylar fossa in either group. Conventional secondary arthroscopy for 2 patients in group A and 3 patients in group B revealed better synovial coverage in group A. Conclusion:In the treatment of ACL tears of MSTL types I and II, compared with conventional reconstruction to clean the synovial sheath of ACL, autologous hamstring tendon reconstruction with preserved synovial sheath combined with remnant suture can lead to better functional recovery at 1 year after operation, though there is no significant difference in function at 2 years after operation.
