膝的结构-滑囊（Bursae）-双语学习
There are up to 13 bursa of various sizes in and around the knee. The fluid filled sacs cushion the joint and reduce friction between muscles, bones, tendons and ligaments. There are bursa located underneath the tendons and ligaments on both the lateral and medial sides of the knee. The prepatellar bursa is one of the larger bursae of the knee and is located on the front of the patella (hence pre-patellar) just under the skin. It protects the patella. Sometimes, whether due to direct trauma or even infection, it can become irritated, swollen, and painful. This is known as prepatellar bursitis. The pes bursa is another important bursa that overlies some of the hamstring tendons which attach to the medial side of the tibia. It too can sometimes become irritated, causing pes bursitis, which can be painful.
膝部及周围有多达13个大小不等的滑囊。这些充满液体的囊状物缓冲关节，能减少肌肉、骨骼、肌腱和韧带之间的摩擦。在膝关节外侧和内侧的肌腱和韧带下方都有滑囊。髌前囊是膝关节较大的囊之一，位于髌骨前部(即髌前囊)皮下，它保护髌骨。有时，无论是由于直接的
创伤，或是感染，都会变得敏感、肿胀和疼痛，这被称为髌前滑囊炎。鹅足滑囊是另一个重要的囊，它覆盖着一些附着在胫骨内侧的腘绳肌腱。它有时也会被刺激，导致鹅足滑囊炎，也很痛苦。
