Dislocation of the polyethylene inlay due to anterior tibial slope in revision total knee arthroplasty

Abstract: We report a case of dislocation of the polyethylene inlay in revision total knee arthroplasty. Eight days after revision arthroplasty due to a previous infection, the polyethylene inlay of a PCL- retaining cemented total knee arthroplasty dislocated at about 80 degrees of flexion on the CPM machine. Lateral X-ray examination revealed an anterior slope of the tibial cut of 5 degrees. Correction of the tibial slope to a posterior tibial slope of 7 degrees reduced the forces on the posterior aspect of the inlay a… Show more

“…Furthermore, no cases were more extended than 88 degrees in sagittal TCA. Some reports showed that an extended position of the tibial component caused loss of flexion angle, loosening, and dislocation of the polyethylene insert [15], [16], [17], [18]. Because no cases showed an extended position of the tibial component in the present study, there was a low risk for such problems using the KneeAlign 2 system.…”

“…It affects anteroposterior stability, range of motion and contact pressure within the tibio-femoral joint. [13][14][15] Contrary to the prediction at the beginning of the study, both external tibial cutting guides with and without a spike were found in the identical accuracy in terms of achieving a desired posterior slope angle. Moreover, we did not find any effect and contribution of a spike embedded to the external guide for the precision of the system.…”

“…Reversed slope jeopardizes knee stability more dramatically. Anterior slope not only decreases flexion amplitude of the knee, but also diminishes flexion space posteriorly causing a seesaw effect and even dislocation of mobile bearings in knee replacements [15]. There is no consensus on the optimal measurement of tibial slope.…”
