摘　　要：BACKGROUND Anterior cruciate ligament reconstruction(ACLR)has a high incidence of re-tear in younger patients.Despite comparable functional outcomes,the incidence of retear using single and double bundle ACLR methods has not been well reported.AIM To hypothesize that double bundle hamstring ACLR has a lower graft rupture rate compared with single bundle hamstring ACLR grafts in young patients.METHODS One hundred and twelve patients<30 years of age at the time of primary double bundle ACLR were eligible for study participation.91(81.3%)could be contacted,with a mean age of 20.4 years(range 13-29)and mean post-operative follow-up time of 59 mo(range 25-107).Telephone questionnaires evaluated the incidence(and timing)of subsequent re-tear and contralateral ACL tear,further surgeries,incidence and time to return to sport,and patient satisfaction.RESULTS Of the 91 patients,there were 6(6.6%,95%CI:1.4-11.7)ACL graft re-ruptures,with a mean time to re-rupture of 28 mo(range 12-84).Fourteen patients(15.4%)experienced a contralateral ACL rupture and 14 patients(15.4%)required further surgery to their ipsilateral knee.fifty patients(54.9%)returned to pre-injury level of sport.Of those<20 years(n=45),4 patients(8.9%,95%CI:0.4-17.3)experienced a re-rupture,with mean time to re-injury 15 mo(range 12-24).Comparative analysis with existing literature and revealed a non-significant Chisquared statistic of 2.348(P=0.125).CONCLUSION A trend existed toward lower graft rupture rates in young patients undergoing double bundle ACLR utilizing a hamstring autograft,compared with rates reported after single bundle ACLR.BACKGROUND Anterior cruciate ligament reconstruction(ACLR) has a high incidence of re-tear in younger patients.Despite comparable functional outcomes,the incidence of retear using single and double bundle ACLR methods has not been well reported.AIM To hypothesize that double bundle hamstring ACLR has a lower graft rupture rate compared with single bundle hamstring ACLR grafts in young patients.METHODS One hundred and twelve patients <30 years of age at the time of primary double bundle ACLR were eligible for study participation.91(81.3%) could be contacted,with a mean age of 20.4 years(range 13-29) and mean post-operative follow-up time of 59 mo(range 25-107).Telephone questionnaires evaluated the incidence(and timing) of subsequent re-tear and contralateral ACL tear,further surgeries,incidence and time to return to sport,and patient satisfaction.RESULTS Of the 91 patients,there were 6(6.6%,95% Cl:1.4-11.7) ACL graft re-ruptures,with a mean time to re-rupture of 28 mo(range 12-84).Fourteen patients(15.4%)experienced a contralateral ACL rupture and 14 patients(15.4%) required further surgery to their ipsilateral knee.fifty patients(54.9%) returned to pre-injury level of sport.Of those <20 years(n=45),4 patients(8.9%,95% Cl:0.4-17.3)experienced a re-rupture,with mean time to re-injury 15 mo(range 12-24).Comparative analysis with existing literature and revealed a non-significant Chisquared statistic of 2.348(P=0.125).CONCLUSION A trend existed toward lower graft rupture rates in young patients undergoing double bundle ACLR utilizing a hamstring autograft,compared with rates reported after single bundle ACLR.
