Outcomes of Robotic Total Hip Arthroplasty
Outcomes of Robotic Total Hip Arthroplasty: A Prospective Study
The objectives of this study are to evaluate the clinical value of robotic-assisted total hip arthroplasty with respect to acetabular cup implantation, and to document the long-term clinical outcome of patients with Total Hip Arthroplasty (THA). IRB approval will be obtained at every study site to evaluate the basic clinical outcomes and post-operative component placement accuracy of each MAKO® THA patient.
The hypothesis is that robotic preparation of the acetabulum will significantly reduce the variability and inaccuracy in the component alignment parameters that lead to post-operative complications, including implant failure.

Retrieval Analysis of implants from revision surgery
時間枠:Up to 10 Years
|
When possible, analysis of the THR components that are removed at revision surgery will be anlaysed for signs of component impingment or signs of damage related to component position.
These observations will be correlated to the clinical reason for revision.
