Total knee replacement (TKR) has been a valid treatment option for end stage joint OA to alleviate pain and restore function of knees that suffer from disease or trauma. TKR affects the kinetics and kinematics of the operated knee. In-vivo and ex-vivo canine TKR kinematic data is currently lacking in dogs. Using a 6-degrees-of-freedom (6-DOF) robotic kinematics system, we tested the hypothesis that TKR would result in statistically significant alterations in stifle kinematics when compared with the intact joint. A joint testing system with 6-DOF (Rotopod R2000) was used to first, cycle the joints through range of motion, second to apply external loads on different stifle flexion angles (135°, 90°, 60°) and lastly to apply gait cycle to 8 cadaveric canine stifles, before and after TKR. Kinematic variables included cranio-caudal translations, internal-external rotations and varus-valgus rotations. A Wilcoxon Rank Sum test was performed. Significance level was set at p< .05. During passive flexion tests, the TKR tibiae moved significantly more caudally than the native tibiae. Significant internal rotation of the TKR tibiae occurred as a result of implantation of the prosthesis. The TKR tibiae had linear internal rotation throughout flexion. Cranio-caudal translation was significantly greater after TKR (p<.01) in 90° and 60°. Internal-external rotation was significantly greater prior to TKR (p< .01) in all flexion angles. Varus-valgus rotation was significantly greater prior to TKR procedure (p<.01) only in 60° of flexion. Stifle joint kinematics are significantly different after TKR. Canine TKR (BioMedtrix) provides semi-constrained technology of the knee. Kinematic data from this ex-vivo study will provide fundamental data to understand and compare in-vivo TKR kinematic.
