Funded Activity Summary

Complications following total knee joint replacement continue to be a major cause for revision surgery and leads to a significant financial burden in terms of health care expenditure. Recent studies suggest that many of these complications are associated with post-surgical pain from the patella knee cap joint, commonly termed anterior knee pain (AKP). Post-surgery AKP may be influenced by the motion of the patella. Recent prospective, randomised trials have compared clinical outcomes between people with TKA in which the patellar surface is replaced (patellar resurfacing) or retained, but have been unable to accurately account for differences in patellar movement in those people with post-surgery complications. To date, studies of patellar motion after total knee replacement have been limited to two-dimensional analyses. This study addresses the technological limitations of previous trials by utilising accurate techniques for directly measuring skeletal motion using kinematic radiostereometric analysis (RSA). These data will measure patellar kinematics in three-dimensions for the first time. This information will allow optimisation of the design of TKA and the surgical techniques required for their implantation. Furthermore, the results will assist in the identification of surgical indications for patellar resurfacing, and the kinematic factors associated with anterior knee pain following total knee replacement surgery.
