We report a case of double-layered lateral meniscus, where an accessory proximal hemimeniscus was overlying the body and posterior horn of the lateral meniscus. The double-layered meniscus arises proximal and parallel to the normal lateral meniscus with its periphery dissociated from the capsule and was significantly thinner and more mobile than its underlying true lateral meniscus. The accessory hemimeniscus was resected arthroscopically.

We report on the case of double-layered medial meniscus, which was overlying anterior to mid portion of the medial meniscus. The upper accessory meniscus was connected to the anterior portion of the normal medial meniscus. And its periphery was connected to the joint capsule. The posterior portion of the upper accessory meniscus was connected to the joint capsule. This case demonstrates an interesting and rare anatomical abnormality of the medial meniscus. We report on the case with a review of the literature.

Snapping syndrome has rarely been reported in the knee. A snapping knee mainly occurs in the case of a translation of the lateral meniscus or a lateral discoid meniscus. Other causes include biceps femoris tendon, semitendinosus iliotibial band, and popliteus tendon. We recently experienced a case of a snapping knee caused by the semitendinosus tendon passing over the medial tibial condyle as a result of trauma.

Recently, studies have emphasized the importance of anatomical placement of the lateral meniscal allograft to decrease postoperative extrusion. However, it is infeasible to identify the exact rotation of the allograft during transplantation. We present a patient who underwent a lateral meniscal transplantation using a wire for correct positioning of the allograft. The use of a wire intraoperatively shaped to resemble the contour of the lateral meniscal allograft will aid in more accurate and anatomical graft placement.

Discoid medial meniscus was first reported in l930 by Watson-Jones. Discoid medial menisci are very rarely reported although the presence of discoid lateral menisci are not uncommon. From Jan. 1989 to Dec. 1994, we have experienced five cases who had discoid medial menisci with pain due to substance tear following knee injury in arthroscopy. There were three complete type anct two incomplete type. Out of flve cases, longitudinal tea1 and bucket-handle type tear were two, respectively. The remained one was a compound tear.

We reported a new technique to repair of the posterior horn tear near the root of the medial meniscus. The radial posterior horn tear near the root showed total loss of the circumferential hoop tension and was similar to the total meniscectomized state. Efforts should be made to restore the circumferential hoop ten-sion and maintain stable bony insertion. We introduced a pull-out repair technique using ACL guide, suture repair set and two PDS No.1. This technique showed stable fixation and good hoop tension of the meniscus. Pull-out repair into the posterior root seems to be a useful method in the posterior horn tear near the root of the medial meniscus.

Meniscus tear is one of the most common knee injuries. The increasing recognition of the importance of the meniscal function has led to a range of new treatments for meniscal tears. A complete radial tear disrupts the circumferential hoop tension of the meniscus. Therefore, restoring its natural architecture is of utmost importance. However, it is difficult to achieve meniscal healing of a complete radial tear due to its structural characteristics. We report five cases of a complete radial tear of the lateral meniscus treated successfully using a fibrin clot that showed good meniscal healing and excellent clinical outcomes.
