RESUMO
We present our technique of repair of meniscal tears in 11 patients using a newly designed stapler, the Polysorb Meniscal Stapler XLS (USS Sports Medicine, Norwalk, CT), to increase the effectiveness and ease of repair of tears in the vascular zone while limiting potential complications. The low-profile stapler comes with a reloadable pistol grip device and a disposable straight or 15 degrees upcurved shaft with a single preloaded 10-mm staple. Standard anteromedial and anterolateral portals were used, along with a superomedial portal for inflow. The portal was enlarged slightly to facilitate introduction of the cannula or the stapler directly into the knee. The nose of the stapler was applied to the superior surface of the inner edge of the meniscal tear. The sharp points on the tip of the nose were used to manipulate the inner edge and coapt the tear site. Firm pressure was applied to the meniscal tissue, and the nose of the stapler was embedded in the inner edge of the meniscus no more than 2 to 3 mm from the tear (as measured along the meniscal surface). The handle was pulled slowly as the staple engaged the meniscal tissue. This step was repeated every 3 to 4 mm to ensure ideal tear stabilization.
