A case of excision of peri-articular cyst and reattachment of meniscotibial ligament with suture anchor

초록

The authors report a case of peri-articular cyst around the knee joint owing to insufficient meniscotibial ligament. After excision, the defective peripheries of the meniscus and capsule were securely re-attached to the margin of the tibial plateau using suture anchors. A 37-year-old man presented with right knee pain. Magnetic resonance imaging revealed a detached meniscotibial ligament (coronary ligament) on the anteromedial side of the knee joint and an elevated deep medial collateral ligament with cystic fluid collection. The cyst was excised by meticulous dissection to expose the free peripheral edge of the meniscus and the margin of the tibial plateau. Two suture anchors were placed immediately beneath the joint line under the subchondral bone. The attachment of the meniscus to the tibial plateau was rendered secure by arthroscopy. At 9 months postoperatively, the patients had no complaints related to the involved knee.
