本港 50 歲以上女士當中，約13%的人就有退化性膝關節炎[1]。但你有沒有想過，女士年紀愈大，罹患骨質疏鬆的情況更是普遍？65歲以上的女士，超過8成人缺乏骨質，亦超過4成人已經患有骨質疏鬆症[2]，這類人士更要及早接受治療[3]。骨質疏鬆通常沒有病徵[2]，影響卻可以很深遠，一旦骨折甚至可能影響往後生活及自理能力，甚至致命[2]。
骨科專科林自強醫生指出，嚴重膝關節炎就算換了人工關節亦非一勞永逸。如同時患骨質疏鬆，康復過程更加要小心，避免換骹後發生骨折令情況變得更加複雜。加上就算不是劇烈運動的碰撞，哪怕是站立水平跌倒都可能引起骨折。如果過往 24個月內曾經發生脆性骨折，或者經檢查後發現骨質密度非常低（如T值低過負3），可視為高風險骨質疏鬆個案[3]，應儘早求醫及接受骨質疏鬆藥物治療，並要考慮使用具備促進骨質生成，同時能減慢骨質流失效果的藥物，每月注射一次，療程持續12個月，儘快提升骨質密度[4]。
