Abstract

The Oxford® Partial Knee has excellent long-term survivorship but high surgical times indicate a learn curve. This retrospective review included a radiographic evaluation of component placement of the initial 300 procedures following conversion from fixed bearing implant use. The anteroposterior and sagittal femoral angles were considered inaccurate in 1.7% and 3.9% of cases, respectively. The anteroposterior and sagittal tibial angles were considered inaccurate in 18.7% and 6.0% of cases, respectively. Overall, a learning curve appears to be present regarding the anteroposterior tibial component angle, with the greatest percentage of inaccuracies occurring within the initial 20 cases.
