Abstract
Systems, methods and devices for tensioning posterior crucial ligaments during cruciate or bi-cruciate ligament-sparing arthroplasty. Non-limiting examples of such systems may include at least one series of tibial inserts of equal size; the at least one series of tibial inserts having at least one set of tibial inserts of equal thickness. The at least one set of tibial inserts of equal thickness may include at least two tibial inserts having different geometries in a posterior portion, the different geometries being configured to change the tension in the posterior cruciate ligament (PCL). The different geometries in the posterior portions of the tibial inserts are configured so as to allow the posterior cruciate ligament to be tensioned or loosened independently of the tibial insert thickness and/or size. By providing different posterior geometries for each insert within a set of a series, a surgeon may be provided with more flexibility in choosing an insert that satisfies stability requirements in a non-invasive manner.
