认识和预防膝关节疼痛

与膝盖骨相连的上下肌腱（股四头肌腱和髌腱），在行走、跑步、跳跃中发挥着重要作用，同时这些运动也会对该肌腱造成劳损，引起疼痛和炎症。它们发炎时称作为跳跃膝。

膝关节是人体最容易受伤的部位之一，各类运动均可发生。跳跃膝在跳跃类体育项目运动员中常见，如排球、篮球运动员等。

症状：

l 爬楼梯、下蹲、行走、跑步等运动时膝关节前方疼痛

l 上楼比下楼疼痛严重

l 膝关节肿胀

l 膝关节活动范围下降

l 膝关节无力

治疗：

休息、调整运动或工作
冰敷
服用消炎止痛药
使用支具
疼痛消失后进行膝关节功能康复锻炼治疗，预防复发。普通人也可进行此类锻炼预防该症发生。主要内容是股四头肌的牵拉训练和力量练习（如下各图示），临床应用时应该制定个性化方案
不建议封闭治疗
注射蛋白酶抑制剂Aprotinin
最后一招：手术治疗
