There are more than 100 different forms of arthritis, although osteoarthritis (OA) and rheumatoid arthritis are the most prevalent (RA) but in contrast to RA, which primarily affects the immune system and can damage joints as well as muscles, connective tissue, tendons and fibrous tissue, OA is the wear and tear of the cartilage that protects the ends of the bones. It can harm any joint, including the hands, hips, knees and spine.
According to an examination of arthritis tests performed in SRL Diagnostics' laboratories, there are more than 180 million cases of arthritis in India, making it more common than many other well-known diseases including diabetes, AIDS and cancer. Every year, approximately 14% of Indians seek medical attention for this joint condition.
按照这文章，俄罗斯非常多。

人家别名就是三哥，你除非查的权威杂志或官方，而且要有年份。我也没说哪一年，而且肯定不是我的统计。
以膝关节为例，根源在脚踝和骨盆肌肉群力结构异常，然后在用力过程中使大腿和小腿肌肉发生扭曲，时间长了膝关节左右受力不均匀，关节软骨磨损了，发现早的就是关节炎，发现晚了就是骨性关节炎。
干体力活多的人，身体的关节长期受力不均匀是很正常的事情。

可能不自觉地姿势就错了，养成了习惯还不容易纠正。
其实 out of alignment，和车开的里程长短没有直接关系。主要是车轮撞了障碍物才容易引起轮子歪掉，比如撞在马路牙子上。
当然从概率上讲，你的说法也没有错哈。
需要他回去在她身边（ 他是独生子，父亲60 左右就去世了）。我问她妈多大？原来只比大我几岁，我差点笑出声。
他解释印度寿命不长。
歪到一定程度就到极限了，然后就会痛。
你看看有几个老人膝盖不痛的，用了一辈子，又不去维护，歪了不是很正常嘛。
你开车不也得经常换机油，而且开个十几年不就换车了
1、根据印度就诊的情况，主要看病的人数成年人是否有1.8亿人有病历记录还是个问题，难道看病的都是关节炎？2、你的报道来自何处，可信度是多少？是否有被引证？3、关节炎多不假，未必都去看病，看病的比例在中国应该不到50%，因为早期都不痛，有的痛了也不去看病的，痛了不做关节炎治的，这样算来都得超过三亿？4、根据我的印度邻居算，印度不比中国潮冷，不至于这么多，4、只是疑问，对我的主题莫影响，我只是提醒关节炎之多，和怎么防护和注意。
我自己所有的车都不需要做Alignment。
