Abstract：Objective To investigate the influence of the anterior cruciate ligament ( ACL ) defects on unicondylar knee arthroplasty ( UKA ) and to clarify whether the ACL’s defects are contraindications of UKA. Methods In this study, we collected data of all the cases of UKA seen from January 2012 to june 2014 in our hospital and had a follow-up for more than 1 year. We divided all the cases into 2 groups by the standard of the preoperative MRI or the deficient ACL in UKA, 1 with intact ACL and the other with deficient ACL. At the end, we clarified whether the rates and reasons of UKA revision from the 2 groups are different. Results The revision rate of the group with deficient ACL was 6.25%, the other groups’ revision rate was 6.63%. chi-square test was used to compare the 2 revision rates and p value was greater than 0.05, there were no statistically significant differences between the 2 groups. The reasons for UKAs’ revision were similar between the 2 groups. Conclusions To the cases with deficient ACL, if there is no preoperative instability, the deficient ACL is not the contraindication for the fixed-bearing UKA.
