ABSTRACT:
The invention provides a system for surgically implanting an allograft or prosthetic ligament as a replacement for a patient's cruciate ligaments. In a practice of the system, as a replacement for an anterior cruciate ligament, the patient's leg is bent and maintained at approximately a ninety degree (90.degree.) angle, a single incision is made medial to the tibial tuberosity. From this incision, under fluoroscopic and arthroscopic contol, a guidewire is driven through the tibia and across the cruciate ligament junctions with the proximal tibia and distal femur ends and into the femur cortex. Succesively larger drills are then turned along the guidewire to form a ligament tunnel, with, as a last step in the tunnel formation process, the preparation of the femur cortex end of the tunnel to receive a femoral connector of the implanted ligament, which connector is arranged in one embodiment to be outwardly flared and in another embodiment to be turned into the appropriately prepared femur end of the ligament tunnel to lock therein. The invention, in addition to the embodiments of the ligament femur end connectors, further includes a tibial surface ligament tibial end connector for both securing the ligament end to the bone and for setting ligament tensioning, of which ligament connectors can be manufactured from a biodegradable material for absorption by the body.
