陈大妈步入中年后，为锻炼身体，开始尝试各种运动，晴天爬山，下雨天爬楼梯。最近两个月她觉得两侧膝盖老有疼痛，上下楼梯的时候更加明显。来院经医生检查发现，她患了膝关节骨关节炎。许多老年人对如何锻炼膝关节还存在一 些认识上的误区，应该加强科普教育，让老年朋友们学会科学的保护膝关节。
误区之一：只要是锻炼，不管什么运动形式，都是有益的
爬山、爬楼梯：爬山、爬楼梯虽是一种很好的锻炼方式，但不利于保护膝关节。因为，上山或爬楼梯时膝关节负重，而下山时除了自身体重以外膝关节还 要负担下冲的力量，这样的冲击会加大对膝关节的损伤。在爬楼梯时，膝关节的弯曲度增加，髌骨与股骨之间的压力也相应增加，从而导致膝关节的疼痛。
