Abstract

Objective

The aim of this work was to compare the prevalence of cyclops lesions after anterior cruciate ligament reconstruction (ACLR) using the single-bundle and remnant bundle preservation techniques.

Materials and methods

One hundred consecutive patients, who had undergone postoperative MRI of the knee followed by arthroscopic ACLR with the remnant bundle preservation technique (R) between February 2007 and August 2010, were enrolled in this study. Thirty-six consecutive patients who underwent ACLR using the single-bundle technique (S) were also included in this study as a control group. The MR findings were scored based on the presence of pre-ACL graft lesion as 0, 1, 2, or 3 on the sagittal images. The sixty-one specimens by second-look surgery (20 in S, 41 in R) were pathologically examined.

Results

The numbers of patients with scores of 0, 1, 2, and 3 were 1, 18, 14, and 3 in group S and 4, 60, 29, and 7, in group R, respectively. Of the 61 patients who underwent second-look surgery (20 in S, 41 in R), eight had a cyclops lesion (three in group S and five in group R). The prevalence of cyclops lesion was not significantly different in group R and group S (p = 0.761).

Conclusions

The prevalence of a cyclops lesion was similar in both groups.
