Case: We present 2 patients each with an intra-articular ganglion cyst arising at the femoral attachment of the anterior cruciate ligament that was successfully resected using the posterior trans-septal portal approach. At the final follow-up, the patients had no recurrence of symptoms and no recurrence of the ganglion cyst on magnetic resonance imaging. Conclusion: Surgeons should consider the trans-septal portal approach when they cannot visually confirm the intra-articular ganglion cyst by the arthroscopic anterior approach. The trans-septal portal approach enabled complete visualization of the ganglion cyst located in the posterior compartment of the knee.
