Differences are reported in the quantities and distribution of uncalcified fibrocartilage at the attachment sites of the quadriceps tendon and the patellar ligament. The largest quantity of fibrocartilage was characteristic of the quadriceps tendon. A prominent wedge of fibrocartilage was seen in the proximal part of the tibial attachment of the patellar ligament, though there was no fibrocartilage in the most superficial fibres. Little fibrocartilage was seen at the patellar attachment of the patellar ligament. According to other workers, there is a similar change in angle (about 35 degrees) between the quadriceps insertion (in relation to the patella) and the tibial attachment of the patellar ligament (in relation to the tibia). However, there is virtually no change in angle at the origin of the patellar ligament (relative to the patella). Thus, fibrocartilage is least conspicuous where there is little motility near an attachment site. It is suggested that the larger amount of fibrocartilage in the quadriceps tendon compared with the tibial attachment of the patellar ligament may be related to the greater absolute size (and particularly anterior-posterior thickness) of the tendon compared with the ligament.
据报道，股四头肌肌腱和髌韧带附着部位未钙化纤维软骨的数量和分布存在差异。纤维软骨数量最多是股四头肌肌腱的特征。在髌韧带胫骨附着处的近端可见一个明显的纤维软骨楔，不过最表层纤维中没有纤维软骨。在髌韧带的髌骨附着处几乎看不到纤维软骨。据其他研究人员称，股四头肌附着处（相对于髌骨）与髌韧带胫骨附着处（相对于胫骨）之间的角度有类似变化（约35度）。然而，髌韧带起点处（相对于髌骨）的角度实际上没有变化。因此，在附着部位附近活动较少的地方，纤维软骨最不明显。有人认为，与髌韧带的胫骨附着处相比，股四头肌肌腱中纤维软骨数量较多可能与肌腱相对于韧带更大的绝对尺寸（尤其是前后厚度）有关。
