Abstract
The relationship between osteoarthritis (OA) of the lower extremity and shoulder OA has not been established. This study evaluated the prevalence of shoulder OA in patients with knee OA. We collected contrast-enhanced computed tomography (CECT) images of the shoulder joints of 105 patients with knee OA that were taken 1 week after they underwent primary knee arthroplasty to check for venous thromboembolism (VTE). The images were compared with CECT images of 110 control-group patients that were taken for the purpose of differentiating VTE. Shoulder OA was present in a significantly higher percentage of patients with knee arthroplasty than controls (29% versus 15%), and the difference was particularly pronounced in patients in their 70s (33%) compared to age-matched controls (11%). Patients with knee OA often use arm support to stand up or walk due to knee joint pain and muscle weakness, which places the weight-bearing shoulder at risk of developing OA.
下肢骨性关节炎（OA）与肩关节OA之间的关系尚未确定。本研究评估了肩关节 OA 在膝关节 OA 患者中的发病率。我们收集了 105 名膝关节 OA 患者在接受初级膝关节置换术一周后的肩关节对比增强计算机断层扫描（CECT）图像，以检查是否存在静脉血栓栓塞（VTE）。这些图像与 110 名对照组患者的 CECT 图像进行了比较，后者是为了区分 VTE 而拍摄的。膝关节置换术患者出现肩关节 OA 的比例明显高于对照组（29% 对 15%），70 多岁的患者（33%）与年龄匹配的对照组（11%）相比，差异尤为明显。膝关节OA患者由于膝关节疼痛和肌肉无力，经常使用手臂支撑站立或行走，这使得负重肩部面临患上OA的风险。
