Potential Association between Anterior Cruciate Ligament Tear and “Bi-Collateral” Ligamentous Rupture: A Retrospective Study

Abstract

Background: Anterior cruciate ligament (ACL) tears are common complications of knee trauma. This entity can be reliably diagnosed by Magnetic Resonance Imaging. There is a lack of data on the epidemiology of ACL tears in Sub-Saharan Africa. The aim of this study is to describe the radiological aspects of post traumatic ACL tears in a black African setting (Yaounde Teaching Hospital). Methods: ninety six (96) MR studies of the knee were retrospectively reviewed. They were realized on a low field device (0.2T) from July 2012 to December 2013. All the examinations were indicated for knee trauma. Ligamentous, meniscal, bony and joint lesions were sought on coronal and sagittal sections. Results: the sample consists of 70% (68/96) of men. The mean age is 35.36 ± 11.86 years. The prevalence of ACL tears is 45.8% (44/96) of which 36 (81.81%, 36/44) are total tears. 23 (24%) have associated meniscal lesion and 8 (8.3%) have a simultaneous damage of the collateral ligaments. The most frequently injured part of the meniscus is its posterior horn (12/23 cases). Meniscal and "bi-collateral" ligament injuries are independently associated to ACL tears. Conclusion: The prevalence of ACL tears at the Yaounde Teaching Hospital is 45.8%. It is independently associated to meniscal tears and concomitant injury of the tibial and fibular collateral ligaments.

Anatomical Risk Factors for Rupture of the Anterior Cruciate Ligament: Magnetic Resonance Imaging Based Knee Joint Assessment

“…This is contrary to the result obtained by Tapouh et al, who found a predominance of full-thickness rupture (81%) [2]. Partial ruptures represented 10% -35% of lesions according to Donell ST et al [10].…”

“…Apart from gender-balanced studies of SonneryCottet et al [7] in France and Helen C. Smith et al [8] in USA who have a majority of female, the male is more represented in most studies. Tapouh et al [2] in Cameroon, found 70.8% males with a sex ratio of 2.43 in a population with knee trauma, Tomas Fernandez-Jaen et al [9] in Spain found 224 men and 84 Women in a population with ACL ruptures, Freychet et al [6] The mean age was 36.6 years in the study population, with a mean of 37.48 years in the control group and 35.5 years in the case group. Tapouh et al [2] who found a mean age of 35.36 years in Cameroonian population found similar results.…”

A mean age of 33.8 years was found by Tomas Fernandez-Jae et al [9] in a study population with ACL rupture in Spain.…”

“…Little is known of its prevalence in sub-Saharan Africa. It was estimated at 45.8% of the traumatic lesions of the knee according to a study published by Tapouh et al in Cameroon in 2015 [2].…”

Management of Endoscopic Portal Hypertension Lesions in Cirrhotic Patients in a Country with Limited Resources: About 603 Cases in the City of Douala in Cameroon

“…In Senegal Bassène et al had recovered respective prevalence of esophageal varices (VO) grade 2 and 3 of 24.3% and 75.7% [7]. In Cameroon, Tapouh et al had a prevalence of 92% VO in cirrhotic patients [8]. The predictive factors of endoscopic PH lesions in cirrhotic patients are first the platelet rate 150.109/mm 3 , the value of elastometry 20 kPa [9]; but also the rate of prothrombin, spleen size, albumin [8] [10].…”
