Abstract:

BACKGROUND: The single-bundle or double-bundle reconstruction methods are commonly used to reconstruct the anterior cruciate ligament at present, while reverse “Y”-plasty reconstruction method is rarely used in clinic.
OBJECTIVE: To compare the long-term clinical curative effect of single-bundle and reverse “Y”-plasty reconstruction method for anterior cruciate ligament reconstruction.
METHODS: From November 2005 to December 2007, the clinical data of 59 patients with anterior cruciate ligament injury who received anterior cruciate ligament reconstruction under arthroscopic were retrospectively analyzed. All patients received the autogenous hamstring tendon as the graft material; the femoral end and the tibial end were fixed with absorbable interference screw. Among them, 31 patients adopted single bundle reconstruction method, and 28 patients adopted reverse “Y”-plasty reconstruction method.
RESULTS AND CONCLUSION: Totally, 59 patients were followed-up for 5 to 7 years. No patient had ligament rerupture, joint pain and limited mobility during follow-up period. The Lysholm score, Larson score and international knee documentation committee knee score in the final follow-up period were significantly higher than those before reconstruction (P < 0.05); there were no significant differences in the Lysholm score, Larson score and international knee documentation committee knee score between follow-up period and preoperation (P > 0.05). In single-bundle group, anterior drawer test results of six cases were mild-positive, Lachman test results of five cases were mild-positive, pivot shift test of nine cases were mild-positive, and seven cases had bone tunnel expansion during X-ray examination. In reverse “Y”-plasty group, anterior drawer test results of seven cases were mild-positive, Lachman test results of four cases were mild-positive, pivot shift test results of two cases were mild-positive, and six cases had bone tunnel expansion during X-ray examination. There was significant difference in the positive rate of pivot shift test between two groups (P < 0.05). The results indicate that both single-bundle and reverse “Y”-plasty reconstruction method can obtain the satisfactory long-term curative effect in anterior cruciate ligament reconstruction, and there are no significant differences in the stability and activity of the knee joint between two methods, but the reverse “Y”-plasty reconstruction method can obtain better rotary stability of knee joint after reconstruction.
