一項新研究主要研究了膝關節癥狀性骨關節炎(OA)患者保留半月板的完整和功能對患者的意義，結果發現保留半月板要比手術切除的預后要好。

在膝癥狀性骨關節炎，軟骨喪失會受到膝關節損傷、肥胖和衰老的影響。半月板切除術后出現膝骨關節炎的癥狀，手術切除所有的受損半月板是相當常見的手術，傳統上被認為是關節損傷需要采用手術治療。

Preserving Meniscus May Be Better Than Surgery
 
A new study sheds light on the critical importance of an intact and functioning meniscus for patients with symptomatic osteoarthritis (OA) of the knee and finds that the trend is to preserve the meniscus rather than remove it by surgery.

In knee OA, cartilage loss is influenced by knee injury, obesity, and age. The onset of knee OA after meniscectomy, the surgical removal of all or part of a torn meniscus, is fairly common and traditionally considered a result of the joint injury that led to the operation in the first place.
