Abstract

The invention discloses a knee-joint cavity implant for treating popliteal cyst. The knee-joint cavity implant comprises a knee-joint cavity sealing sheet (12) and a stop sheet (16), wherein a through hole (14) is opened in the knee-joint cavity sealing sheet (12); the peripheral area of the stop sheet (16) is fixed on the knee-joint cavity sealing sheet (12), thus the stop sheet (16) is capable of shielding the through hole (14); moreover, a flow through hole (162) is opened in the junction of the peripheral area of the stop sheet (16) and the knee-joint cavity sealing sheet (12), thus the stop sheet (16) and the knee-joint cavity sealing sheet (12) are capable of forming a flow cavity (20). The knee-joint cavity implant above is capable of effectively improving the treatment effect on popliteal cyst.
