Hubungan Morfologi Tibial Eminence dengan Cedera Anterior Cruciate Ligament pada Pasien Poliklinik Orthopaedi dan Traumatologi Rumah Sakit Umum Pusat Haji Adam Malik Medan Tahun 2021 – 2023

Abstract

Background: The anterior cruciate ligament (ACL) plays an important role in maintaining knee stability and rupture of this ligament is one of the most common injuries. Various factors are reported to increase the risk of ACL rupture. Recent studies have suggested that tibial eminence width and height may also increase the risk of ACL rupture. This study aims to evaluate the relationship of tibial eminence width and height with ACL rupture. Methods: This study was an observational analytic study with a cross sectional design. Inclusion criteria were: individuals aged 18-59 years; diagnosis of ACL rupture based on MRI. All subjects with a history of pathological abnormalities of the knee were excluded. The width and height of the tibial eminence were measured by a knee anteroposterior X-ray. Height was measured by the cephalocaudal length of the tibial eminence, and width was measured by the horizontal length of the tibial eminence. Results: This study included 45 subjects, consisting of 25 (55.55%) subjects with ACL rupture and 20 (44.44%) without ACL rupture. The height of medial tibial eminence was smaller in ACL rupture group than the control group (9.02 ± 1.66 mm vs 10.61 ± 1.09 mm), Eta = 0.411. The lateral tibial eminence height was higher in the control group than the ACL rupture group (10.16±1.04 mm vs 8.98±1.55 mm), Eta = 0.406. The width of tibial eminence was greater in the control group than the ACL rupture group (13.70±2.19 mm 9.92±2.76 mm), Eta = 0.607. Conclusion: There is an association between tibial eminence morphology and the incidence of ACL rupture, particularly shown on the tibial eminence width, medial tibial eminence width, and lateral tibial eminence height. Keywords: ACL rupture, eminence height, lateral eminence, medial eminence, tibial eminence.
