The purpose of this study was to investigate the incidence of cyclops lesions and its relationship with the cross-sectional area of the intercondylar notch.
For this study, 55 patients (24 male and 31 female) underwent follow-up arthroscopy after bi-socket anterior cruciate ligament reconstruction with hamstring tendon grafts were included. All patients underwent magnetic resonance imaging measurements of intercondylar notch dimensions. We compared the femoral intercondylar notch sizes and bone tunnel sizes between knees with cyclops lesions (cyclops group) and those without cyclops lesions (no-cyclops group). The mean percentage of the tunnel size to the cross-sectional area of the femoral intercondylar notch was also compared between the groups. The median follow-up duration was 3.8 years.
Cyclops lesions were found in 15 of the 55 knees (27.3 %) on second-look arthroscopy (cyclops group). Only 6 of the 55 knees (10.9 %) had extension loss (cyclops syndrome). The cyclops group included 3 men and 12 women. The two groups showed a statistical difference in sex variation (P = 0.04). No significant differences were found in the femoral and tibial tunnel sizes between the two groups. The cross-sectional area of the femoral intercondylar notch was significantly smaller in the cyclops group (251.7 ± 63.2 mm(2)) than in the no-cyclops group (335.6 ± 77.6 mm(2)) (P < 0.001). The percentage of the total femoral tunnel size to the cross-sectional area of the femoral intercondylar notch was significantly higher in the cyclops group (18.6 ± 5.3 %) than in the no-cyclops group (13.2 ± 3.6 %) (P = 0.02).
A smaller intercondylar notch size may be a potential risk factor for cyclops lesion formation.

本研究旨在调查独眼巨人病变的发生率及其与髁间切迹横截面积的关系。
本研究纳入了55例患者（24例男性和31例女性），这些患者在接受了双束自体腘绳肌腱移植重建前交叉韧带后接受了随访关节镜检查。所有患者均接受了髁间切迹尺寸的磁共振成像测量。我们比较了有独眼巨人病变的膝关节（独眼巨人组）和没有独眼巨人病变的膝关节（无独眼巨人组）之间的股骨髁间切迹尺寸和骨隧道尺寸。还比较了两组之间隧道尺寸占股骨髁间切迹横截面积的平均百分比。中位随访时间为3.8年。
在二次关节镜检查中，55例膝关节中有15例（27.3%）发现了独眼巨人病变（独眼巨人组）。55例膝关节中只有6例（10.9%）出现伸直受限（独眼巨人综合征）。独眼巨人组包括3名男性和12名女性。两组在性别差异方面存在统计学差异（P = 0.04）。两组之间的股骨和胫骨隧道尺寸没有显著差异。独眼巨人组的股骨髁间切迹横截面积（2
