An Improved Tibial Force Sensor to Compute Contact Forces and Contact Locations In Vitro After Total Knee Arthroplasty

Abstract: Contact force imbalance and contact kinematics (i.e., motion of the contact location in each compartment during flexion) of the tibiofemoral joint are both important predictors of a patient's outcome following total knee arthroplasty (TKA). Previous tibial force sensors have limitations in that they either did not determine contact forces and contact locations independently in the medial and lateral compartments or only did so within restricted areas of the tibial insert, which prevented them from thoroughly e… Show more

“…The tibial force sensor developed by the authors was used for these analyses, because its size, shape, and curvature match those of a standard tibial component [10]. This sensor is described in detail elsewhere [10], but briefly it may be broken down into five layers (Fig. 1).…”

“…A useful instrument to determine tibial contact locations is a tibial force sensor, because it can simultaneously determine both contact locations and contact forces. When using a tibial force sensor, the contact locations are computed as the centers of pressure in the medial and lateral compartments of the tibia [10]. Thus, accurately computing contact locations using a tibial force sensor is important for objective evaluations of innovations based on tibiofemoral contact kinematics.…”
