骨关节炎运动损伤Osteoarthritis osteoarthritis, athletic injury and collogen 骨关节炎Osteoarthritis 骨关节炎(osteoarthritis)又名退行性骨关节炎，为关节软骨发生退行性变，并在关节边缘有骨刺形成。骨关节炎多见于老年人，随着人类平均寿命的延长，骨关节炎的发病率愈来越高，它严重妨碍工作，成为50岁以后丧失劳动力的第二个常见原因。The osteoarthritis other name recession osteoarthritis, has the degeneration for the articular cartilage, and has the spur formation in the joint edge. The osteoarthritis sees in the senior citizen, along with the human mean lifetimes extension, osteoarthritiss disease incidence rate comes to be higher, it hinders the work seriously, will become 50 year old of later disabled the second common reason.　骨关节炎可分为原发性和继发性骨关节炎两大类，原发性主要为关节软骨的退行性老化病变，随着年龄的增长而日渐加重，软骨是所有结缔组织中老化现象较显著的组织，软骨老化是正常的生理演变，但可以在遗传的基础上因人而异，有的发生较早，比较快速，也有的发生较晚，较缓慢，一般病情进展与疲劳过度及关节负担过重有关。继发性骨关节炎即先有其它疾病如先天性发育异常、外伤、骨骼的缺血坏死、下肢不等长及畸形等，而逐渐导致关节软骨的病变。此外，骨关节炎还可能因不适当地长期大量激素及局部的放射线治疗所引起。The osteoarthritis may divide into primary and the sequential osteoarthritis two broad headings, the primary stage mainly for articular cartilages recession aging pathological change, along with age growth, but aggravates day after day, the cartilage is all knots contracts in the organization the ageing phenomenon remarkable organization, the cartilage aging is the normal physiological evolution, but may be different from person to person in the heredity foundation, some occurrences, are quite early fast, some occurrences are also late, is slow, generally the condition progress and weary excessively and the joint burden concerns overweight. The sequential osteoarthritis namely has other disease like congenitalness growth exceptionally, the flesh wound, skeletons ischemia necrosis, the lower limb not to wait for long and abnormal and so on first, but causes articular cartilages pathological change gradually. In addition, because the osteoarthritis also possible not suitably the long-term massive hormones and the partial radioactive rays treatment cause.肥胖患者关节负重增加，人体为维持重心会发生膝部的内翻畸形，使膝关节两侧间隙负重不平衡，导致退行性变，积累性的微小损伤可造成软骨下骨的硬化改变，影响关节
