Popliteal pain or pressure — Popliteal pain or pressure can accompany any
of the above pain patterns. It is most commonly caused by the buildup of
pressure from a large, acute effusion （关节积液）. When the patient flexes
the knee in the presence of an effusion, the quadriceps mechanism forces the
fluid posteriorly. Pressure is exerted on the gastrocnemius muscle （腓肠肌
）, vascular structures, and the branches of the sciatic nerve （坐骨神经）
, leading to local pain, lower extremity edema, and even sciatica,
respectively. Over time, if the effusion persists, this pressure leads to
the formation of a Baker's cyst, a natural extension of the chronic knee
effusion. (See 'Popliteal cyst' below.)
其他的原因还有半月板，韧带，滑囊炎，肌腱拉伤等等
不放心，没有好转很长时间，去拍个片，做个ＭＲＩ
