Abstract

|
|
Purpose:The object of this study is to compare the Insall-Salvati ratio and Carton index between the patients who have an anterior cruciate ligament (ACL) tear and the patients who have no ACL tear.
Materials and Methods:The study group included 114 patients who had an ACL tear and received arthroscopic reconstruction. The group I was acute ACL tear group, within 3 weeks after injury. The group II was chronic ACL tear group who had MRI was done after 3 weeks from injury. The group III was normal control group. We measured the Insall-Salvati ratio and Carton index on Magnetic Resonance Images (MRI) for all patients.
Results:The Insall-Salvati ratio of control group was 1.02±0.12 and Carton index of control group was 1.14±0.16. The ACLtear study group was 0.91±0.12 and 0.89±0.20 respectively. The Insall-Salvati ratio and Caton index in ACL tear group was significantly less than those of control group. There were no significant differences in comparing with acute and chronic ACL tear group.
Conclusions:Our study show that patella baja has an association with ACL tears, therefore in patients with an ACL tear who had patella baja, ideal graft for reconstruction was seriously considered.
