Abstract: The present disclosure provides a meniscal allograft transplantation system and methods of use.

Abstract: A mower path assistance system to encircle an obstacle projecting from a ground surface, including a barrier mat formed with a barrier mat aperture enclosed by the barrier mat and having a barrier mat aperture diameter, a perimeter edge, and a barrier mat installation slit extending from the perimeter edge to the barrier mat aperture, wherein the barrier mat is deformable around the barrier mat installation slit to create a pathway having a pathway width through which the obstacle may pass from the perimeter to the barrier mat aperture. The barrier mat has a plurality of edges with axes that intersect at obtuse angles.

Abstract: Devices and methods for positioning a patient's leg during a leg or knee operation by employing a novel surgical leg positioning device. The device has a low profile so that it can remain under sterile surgical drapes during an operation, and prevents the leg from moving out or up. Large, easy to access, buttons are provided to allow the surgical leg positioning device to be manipulated while under sterile surgical drapes so that it may be moved when no longer needed.

Abstract: A meniscal allograft with a bone block having a trapezoidal shape in cross-section and a technique for using a meniscus allograft having a trapezoidal shaped bone block are disclosed. A groove is formed initially in the bone using drill bits. Dilators are used to increase the size of the drilled groove. The orthogonal corner at the bottom of the groove is shaped using a rasp. A smooth dilator compacts the bone in the acute angle at the bottom of the groove opposite the orthogonal corner to create the final trapezoid shape of the bone groove. A meniscal allograft having a bone block of corresponding trapezoidal shape is prepared using a workstation and three cutting jigs to make three corresponding cuts. The trapezoidal bone block of the meniscal allograft is then installed within the bone groove.
