膝關節內視鏡手術的定義
膝關節內視鏡手術(又稱鎖孔手術或微創手術)是一種醫師將攝影機從皮膚上開的小孔進入體內，診斷及治療膝蓋常見問題，同時避免在皮膚上開大洞的手術。醫師會藉此方法診斷如軟骨撕裂、韌帶傷害和關節炎等問題。此手術可降低疼痛的感覺，加快復原速度。
為什麼要進行膝關節內視鏡手術？
此手術的目的是為了確認患者的膝關節問題，並在確認後可以直接治療。若您有下列膝蓋問題，建議可以使用膝關節內視鏡手術：
- 半月板撕裂：半月板是在膝蓋骨間的空隙做為緩衝用途的軟骨；手術可修復或取出半月板。
- 前十字韌帶或後十字韌帶的撕裂或傷害。
- 關節襯層腫脹、發炎或受損：此襯層稱為滑囊。
- 膝蓋骨(又稱髕骨)位置不正。
- 膝關節軟骨斷裂的小碎片。
- 移除貝克氏囊腫(Baker’s cyst，又稱膕窩囊腫)：這是因為膝後充滿液體所造成的腫脹；有時候關節炎等其他原因造成的腫脹、疼痛，及發炎也會造成這個問題。
- 膝蓋的部分骨折。
膝關節內視鏡手術的風險因素
手術結果可能會視您的膝蓋受傷程度而定，舉例來說，如果您膝蓋裡的關節軟骨已完全磨損掉的話，完全復原是不太可能的。您可能需要改變生活型態，亦即可能得限制自己的活動方式，並尋找替代性的低衝擊運動。手術前明白風險和併發症十分重要。若您有任何問題，請諮詢您的醫師，以獲得更多資訊。
- 傷到膝蓋周圍的神經。
- 傷口下方出現腫塊。

- 如果您對關節鏡手術的風險有疑慮，您可以與醫師討論其他治療方法，如磁振造影等也可以診斷出問題，但是確認問題存在後，您可能仍需要關節鏡手術治療該問題。
