Meniscal tears are common in Kenya, with prevalence rates ranging from 45 to 78% of intracapsular knee pathology. Diagnosis of these injuries relies on the use of both clinical signs and symptoms as well as radiological investigations. In a few instances, radiological detection could be difficult, partly because of variant attachment patterns of the medial meniscal anterior horn. Some of these unusual attachments of the anterior horn of the medial meniscus could even be mistaken for meniscal tears. There is also evidence that these variations differ from population to population. This study, therefore, aimed to determine the variant bony and ligamentous attachments of the medial meniscal anterior horn in a sample Kenyan population.
The study was conducted at the Department of Human Anatomy, University of Nairobi. Thirty-one male and female unpaired medial menisci were obtained from cadaveric specimen. The bony and ligamentous attachments were identified and recorded and photomacrographs taken.
The bony attachments different from the classical textbook attachment accounted for 54.8% of the medial meniscal anterior horns. The anterior intermeniscal ligament was present in 62.3% while 16.2% showed attachment to the anterior cruciate ligament. Twenty-nine percent (29%) of the medial menisci studied did not have any ligamentous attachments.
The bony and ligamentous attachments of the medial meniscal anterior horn are highly variable presenting unique diagnostic and therapeutic challenges. A new classification of ligamentous attachments is thus proposed.
在肯尼亚，半月板撕裂很常见，占关节内膝关节病变的 45%至 78%。这些损伤的诊断依赖于临床体征和症状以及影像学检查。在少数情况下，放射学检测可能很困难，部分原因是内侧半月板前角的附着模式存在变异。这些内侧半月板前角的一些不寻常附着甚至可能被误认为是半月板撕裂。也有证据表明，这些变异在不同人群中存在差异。因此，本研究旨在确定肯尼亚人群中内侧半月板前角的变异骨和韧带附着。
该研究在肯尼亚内罗毕大学人体解剖学系进行。从尸体标本中获得 31 个男性和女性未配对的内侧半月板。确定并记录了骨和韧带附着，并拍摄了照片。
与经典教科书附着不同的骨附着占内侧半月板前角的 54.8%。前交叉韧带内半月板前韧带存在于 62.3%，而 16.2%显示与前交叉韧带附着。研究的 29%（29%）的内侧半月板没有任何韧带附着。
内侧半月板前角的骨和韧带附着具有高度变异性，带来独特的诊断和治疗挑战。因此，提出了一种新的韧带附着分类。
