An arthroscopic Resection Technique for Popliteal Cysts

When treating a popliteal cyst in the knee joint, it is often necessary to simultaneously treat the intra-articular lesions so as to reduce the recurrence of the cyst after the operation. Herein, we propose an arthroscopic resection technique for popliteal cyst, in which the position of the popliteal cyst is indirectly located by finding out the location of the semimembranosus tendon during the operation, thereby completing the arthroscopic resection of the popliteal cyst. This method does not involve the posteromedial compartment of the knee joint. Arthroscopic treatment can be performed on the combined intra-articular lesions through anteromedial and anterolateral approaches before or after popliteal cyst resection.
