Fig 4.

The tip of the Viper is inserted and rotated down into the position. The primary suture is positioned 5 to 10 mm apart from the tear site toward the middle segment side. The Viper hook is gripped along the meniscal outer rim, and the needle is inserted. The hook should hang deep, and the needle insertion should be near the anterior margin of the lateral meniscus to bundle the circumference fiber of the meniscus more. By pushing the needle toward the hook through the substantial meniscus, the needle tip captures the looped no. 2-0 FiberWire.
