Seconda...

Patellofemoral joint between the Femur and the Patella OA can occur in either or both of these articulations of the knee, it is usual that the patell...

    The process of osteoarthritis affects the articular cartilage (mainly type II) that covers the articular surfaces of bone. Articular cartilage is normally maintained in a healthy equilibrium of chemical reactions, however, when OA starts to develop the reactions are disrupted leading to changes in the collagen of the cartilage: 1. Disruption in the...

    膝外翻或膝關節交鎖 (lock knee) 會增加膝內側腔室的壓力。 足部過度內翻會使脛骨在足部負重時出現內轉,股骨因而要作同樣內轉以鬆解膝部的扭力,此舉令膝蓋外走而令其底部與股骨外髁出現磨擦。

  7. 2023年7月14日 · 骨关节炎是一种退行性关节疾病。 它会导致疼痛、肿胀和僵硬,影响人自由活动的能力。 骨关节炎影响整个关节,包括关节周围的组织。 它最常见于膝关节、髋关节、脊柱和手关节。 导致骨关节炎的因素有很多,其中包括关节损伤史或过度使用、年龄较长以及体重超重。 骨关节炎对女性的影响大于男性。 通过运动和健康饮食来锻炼强健的肌肉并保持健康体重可以减轻症状。 严重病例可行关节置换术以减轻疼痛和恢复活动能力。 一旦疼痛和活动功能丧失成为慢性病,骨关节炎患者在参加有意义的活动时往往会受到限制,幸福感下降,并出现心理困扰。 问题的范围. 在肌肉骨骼疾病中,骨关节炎是导致残疾生命年的重要因素之一。 由于骨关节炎多发于老年人(约70%年龄在55岁以上),随着人口老龄化,全球患病率预计将有所上升。
