Loss of terminal knee extension after anterior cruciate ligament (ACL) reconstruction is problematic. Formation of a fibrous nodule, known as a cyclops lesion, at the site of the ACL graft exiting from the tibial tunnel can impinge at the roof of the intercondylar notch and block terminal knee extension. This article presents a case of an inverted cyclops lesion originating from the femoral tunnel site of the ACL graft, representing a variant of the traditional cyclops lesion. The lesion was identified by clinical examination including prone heel-height difference assessment in combination with magnetic resonance imaging arthrography. The lesion was treated successfully by arthroscopic resection, with rapid resolution of the patient's painful, symptomatic extension loss.
前交叉韧带（ACL）重建术后出现终末膝伸展受限是个问题。在ACL移植物从胫骨隧道穿出的部位形成的纤维性结节，即所谓的“独眼巨人病变”，可压迫髁间切迹顶部并阻碍终末膝伸展。本文介绍了一例源自ACL移植物股骨隧道部位的倒置独眼巨人病变病例，这是传统独眼巨人病变的一种变体。通过包括俯卧位足跟高度差异评估在内的临床检查并结合磁共振关节造影来识别该病变。通过关节镜下切除成功治疗了该病变，患者疼痛性、有症状的伸展受限迅速得到缓解。
