退化性關節炎是老化關節所形成的關節炎。一般症狀就是膝關節酸痛、腫脹、變形及行走困難。全身關節都可能發生但以膝關節為最常見。女性比男性多，六十歲以上的人更常見。
Treatment治療：
The treatment depends on symptoms: for the early stage patient, it can be treated with anti-inflammatory pain relievers, physical therapy, or intra-articular injections; for the patients with severe symptoms, joints that are damaged, severely deformed, or have difficulty walking, evaluated by a doctor to see if the surgery is needed (joint replacement).
視關節炎病變輕重程度而異：在早期病患，採取保守治療，藥物可消炎止痛，物理治療或關節內注射藥物。若症狀嚴重，病灶已在關節面磨損殆盡，造成關節變形行走困難，經醫師診斷後是否採取手術治療行全膝關節置換手術。
