Abstract

The standard of care treatment for end-stage osteoarthritis of the knee joint is a total knee arthroplasty (TKA). As we move towards a younger TKA patient cohort, implant longevity is of increasing concern. Porous hydroxyapatite coated uncemented implants provide a promising alternative to cemented fixation methods. Currently, a lack of consensus exists regarding which surgical technique is best suited to the uncemented TKA procedure. This thesis sought to examine the impact of surgical technique on tibial and femoral component migration. Additionally, we investigated the impact of technique on post-operative kinematics and functional recovery. The results of this thesis indicate no significant effect of surgical technique on one year migration of the tibial and femoral components or on post-operative kinematics, condylar liftoff, and function. In conclusion, this thesis provides support for the use of a single-radius cruciate-retaining porous hydroxyapatite coated uncemented implant as a viable alternative to cemented TKA.
