Articular cartilage surfaces of 49 human patellae and 24 distal femora were characterized by identifying distinctive features with surface curvature analysis. Paired specimens from the same donor generally exhibited natural symmetry, so only results from nonpaired specimens were considered (39 patellae and 19 femora). In 23 of 39 patellae, proximal median and lateral transverse ridges extended to form an oblique ridge resembling a skewed lambda (lambda). Most of the unpaired patellae (37 of 39) exhibited only a single lateral transverse ridge, and most (32 of 39) had an odd facet. All but one patella exhibited a concave depression in the lateral and medial facets and a sellar area in the proximal region. All distal femoral surfaces exhibited a sellar trochlea. The concavity of the trochlea was greatest in the posterior aspect, near the intercondylar notch.
通过表面曲率分析识别独特特征,对49个人类髌骨和24个股骨远端的关节软骨表面进行了表征。来自同一供体的配对标本通常呈现自然对称性,因此仅考虑非配对标本的结果(39个髌骨和19个股骨)。在39个髌骨中的23个中,近端正中嵴和外侧横行嵴延伸形成一条类似于斜λ形的斜嵴。大多数非配对髌骨(39个中的37个)仅表现出一条外侧横行嵴,并且大多数(39个中的32个)有一个奇数小平面。除了一个髌骨外,所有髌骨在外侧和内侧小平面均表现出凹陷,在近端区域有一个鞍状区域。所有股骨远端表面均表现出鞍状滑车。滑车的凹陷在后部最大,靠近髁间切迹。
