Brief summary
We aim to measure the migration pattern of the tibial base plats using RSA. We would also like to compare RSA and clinical questionnaire data (oxford knee score and EQ5D score) regarding Genesis II MIS tibial base plate to a previous study involving standard Genesis II tibial base plates
Interventions
Genesis II MIS Tibial Base Plate As the advantages of minimally invasive techniques have become apparent, increasing numbers of surgeons are seeking to incorporate MIS into their practices – without clinical compromises. Instrumentation improvement has allowed surgery to be performed through small incisions with a reduction in soft tissue trauma. The next step in the evolution of MIS lies in the modification of the implants themselves. The GENESIS II Minimally Invasive Tibial Baseplate represents the new standard in minimally invasive implants. Built on the successful implant design history and proven track record of GENESIS, the MIS baseplate has been specifically designed and tested for minimally invasive techniques. Available for use with both Cruciate Retaining and Posterior Stabilized components, the GENESIS II MIS Tibial Baseplate features a shorter post (20 mm) and fins. This allows easier insertion through a small incision without tibial subluxation, resulting in less stress on the incision itself and the extensor mechanism, as well as less soft tissue trauma. The MIS baseplate maintains 80% of the GENESIS II baseplate’s fins to ensure that there is no compromise in fixation and rotational stability.
