O型腿在医学上称为膝内翻,俗称“罗圈腿”、“弓形腿”、“箩筐腿”。指的是在膝关节处,小腿的胫骨向内旋转了一个角度,故此称为“膝内翻”。

缺钙和遗传是O型腿形成的两个基础,但更直接的原因,还是在于走姿、站姿、坐姿及一些运动。

膝外翻又称碰腿症,俗称“外八字腿”,是较常见的下肢畸形。其畸形与膝内翻相反,两下肢自然伸直或站立时,当两膝相碰,两足内踝分离而不能靠拢。两下肢膝外翻者,形如“X”状,故又名“X”形腿。单下肢膝外翻者,状如“K”字形,又名“K”形腿。

 非常复杂,主要是由于以下原因所导致:1,佝偻病或骨软化病(其原因是缺乏维生素d)所引起的膝部畸形;2,脊髓前角灰质炎导致股骨或胫骨发育异常;3,骨腄损伤导致股骨或胫骨发育异常;4,骨髓炎导致股骨或胫骨发育异常;5,其它疾病(如骨折、外伤、骨瘤等引起的后遗症)导致股骨或胫骨发育异常。

 与O型腿相反,x型腿是指两足并立时,首先是两侧膝关节碰在一起,而两足足跟则靠拢不了,走路出现两膝“打架”互碰的步态。
