Abstract:
Objective To evaluate and compare the maturity of autografts and allografts as well as the postoperative clinical outcomes 10 years after anterior cruciate ligament reconstruction(ACLR).Methods A retrospective analysis was conducted on 64 patients who underwent anterior cruciate liga-ment reconstruction,with an average follow-up period of about 10 years.Autografts were used in 36 cases(56.2%),and allografts in 28 cases(43.8%).Both groups were recorded the knee Lysholm scores,IKDC subjective scores,and stability tests results(KT-1000 side-to-side difference and Lach-man test).Moreover,graft maturity was assessed using the knee magnetic resonance imaging(MRI),and the Signal-to-Noise Quotient(SNQ)for both types of grafts was measured.Results No significant differences were observed between the autograft and allograft groups in the average follow-up time(10.1±2.1 and 10.5±1.8 years)(P=0.376),the SNQ value(24.1±8.8 and 23.2±8.7)(P= 0.652),the Lysholm score(90±10.3 and 89.4±8.9)(P=0.805)and the anterior joint stability dur-ing follow-up(P=0.923).Moreover,the average IKDC score and incidence of abnormal tension of the ligament measured by KT1000 of the autograft group were higher than the allograft group[(84.5±8.3)vs.(80.4±7.8),P=0.075;14.3%vs.8.3%,P=0.724].Meanwhile,ACL re-tear occurred to two cas-es in the autograft group(5.6%)and the allograft group(7.1%),respectively,showing no significant dif-ference(P=0.795).Conclusion Ten years after ACLR,no significant differences are found in graft ma-turity,clinical outcomes,or joint stability between patients using autografts and allografts.Moreover,the rate of graft re-tear is comparable between the two groups.
