Embodiment Construction

[0033]One embodiment of the invention is a ligament repair system which collectively comprises the following Figure 1-7 The shown femoral aimer assembly 100, as Figure 8-12 The shown tibial aimer assembly 200 includes a femoral fixation assembly of a first fixation device and a second fixation device, and as Figure 13-24 The tibial fixation assembly 300 is shown. As will be described further herein, components of the system can be used to perform a method of implanting a posterior cruciate ligament (PCL) replacement graft.

[0034] An embodiment of the femoral aimer assembly 100 is in Figure 1-7 shown in . handle 110 in Figure 1-4 is depicted in , and includes at least a grip surface 112 and a release button 114 . The release button 114 is configured to release the cannula 120 from the first cannula opening 115 or the second cannula opening 116 when depressed. The exemplary release button 114 is spring biased to create a lock between the handle 110 and the sleeve 12...

Abstract

Embodiments of the present invention are directed to a ligament repair system and method. A ligament repair system may include one or more of a femoral sight assembly, a tibial sight assembly, a femoral fixation assembly, and a tibial fixation assembly.

Description

technical field [0001] The present invention relates generally to the field of medical device instruments, and more particularly to systems and methods for repairing or replacing ligaments. Exemplary systems and methods may be used to repair or replace a posterior cruciate ligament (PCL), including individually articulating individual bundles of the PCL. Background technique [0002] When a ligament such as the PCL experiences trauma or other injury or condition, the ligament may become permanently loose or may be torn. In such conditions, the ligaments cannot function properly. In the setting of PCL dysfunction, the tibia may translate posteriorly relative to the femur, and the stability of the knee may be greatly reduced. In order to restore biomechanical function, the PCL or replacement graft must be securely fixed in an anatomically correct position within the knee. Anatomically correct positioning can be achieved by positioning the graft at the natural tibial and fem...
