We report the case of an inverted cyclops lesion limiting extension of the knee joint after a four-strand hamstring anterior cruciate ligament (ACL) reconstruction. One case has been reported previously following a bone-tendon-bone reconstruction of the ACL but a similar case has not been reported.

Abstract Background Cyclops lesion is the second most common cause of extension loss after anterior cruciate ligament reconstruction. This study focused on the correlation between the anatomy of the intercondylar notch and the incidence of cyclops lesion. To determine whether the size and shape of the intercondylar notch are related to cyclops lesion formation following anterior cruciate ligament reconstruction according to magnetic resonance imaging (MRI) findings. Methods One hundred twenty-five (125) patients were retrospectively evaluated. The notch width index (NWI) and notch shape index (NSI) were measured based on coronal and axial MRI sections in patients diagnosed with cyclops syndrome (n = 25), diagnosed with complete anterior cruciate ligament (ACL) tears (n = 50), and without cyclops lesions or ACL ruptures (n = 50). Results Imaging analysis results showed that the cyclops and ACL groups had lower mean NWI and NSI values than the control group. Significant between-group differences were found in NSI (p = 0.0140) based on coronal cross-sections and in NWI (p = 0.0026) and NSI (p < 0.0001) based on axial sections. Conclusions The geometry of the intercondylar notch was found to be associated with the risk of cyclops lesion formation and ACL rupture.

Introduction. Cyclops syndrome is one of the causes of failure of anterior cruciate ligament reconstruction. The aim of the study was to examine the quality of life of patients who had this complication and its consequences till the return to unrestricted (sports) activities. Material and Methods. During an eighteen-year follow-up of 4330 patients, cyclops syndrome was found in 71 patients (1.64%). This study included 60 of them, who agreed to fill out a questionnaire and functional scoring scales. Results and Discussion. The mean Tegner score was 5.95 and Lysholm score was 86.13 points. After the arthroscopic removal of cyclops lesion, excellent results were found in 22 patients (36.7%), good in 19 (31.7%), poor in 16 (26.7%) and very poor in three cases (5%). On average, athletes lose 10 months from injury to anterior cruciate ligament reconstruction. It takes at least 6 months to return to competitive sports. If cyclops lesion occurs, it takes approximately 10 months to arthroscopy, and on average 3 months of postoperative recovery. Conclusion. Cyclops lesion is a complication that significantly compromises the outcome of anterior cruciate ligament reconstruction, in terms of functional scores, subjective symptoms, the intensity of sports activities, and quality of life. Arthroscopic removal of the cyclops lesion leads to satisfactory postoperative results, but athletes lose 2.5 years on the whole, from injury to return to unrestricted sports activities.
