Wear-related failures and instabilities are frequent failure mechanisms of total knee replacements.
High-conforming designs may provide additional stability for the joint.
This study analyzes the effects of a ligamentous insufficiency on the stability and the wear behavior of a high-conforming knee design.
Methods.
Two simulator wear tests were performed on a high-conforming total knee replacement design.
In the first, a ligamentous-stable knee replacement with a sacrificed anterior cruciate ligament was simulated.
In the second, a ligamentous-unstable knee with additionally insufficient posterior cruciate ligament and medial collateral ligament was simulated.
Wear was determined gravimetrically and wear particles were analyzed.
Implant kinematics was recorded during simulation.
Results.
Significantly higher wear rates ( P ≤ 0.001 ) were observed for the unstable knee ( 14.58 ± 0.56 mg/106 cycles) compared to the stable knee ( 7.97 ± 0.87 mg/106 cycles).
A higher number of wear particles with only small differences in wear particle characteristics were observed.
Under unstable knee conditions, kinematics increased significantly for translations and rotations ( P ≤ 0.01 ).
This increase was mainly attributed to higher tibial posterior translation and internal rotations.
Conclusion.
Higher kinematics under unstable test conditions is a result of insufficient stabilization via implant design.
Due to the higher kinematics, increased wear was observed in this study.
