Summary: The internal rotational position of the femoral component in TKA can have a positive impact on knee kinematics.

Background

Femoral and tibial component positions and intraoperative knee kinematics, comprising medial pivot motion from knee extension to flexion, are important factors for postoperative knee range of motion and clinical outcomes after total knee arthroplasty (TKA). This study aimed to examine the relationship between intraoperative knee kinematics measured in TKA using a computer-navigation system and the positions of the femoral and tibial components calculated with computed tomography data.
Patients and Methods: From 2015 to 2018, 44 patients (48 knees) who underwent primary TKA were included. All TKA procedures and intraoperative knee kinematic measurements were performed using a navigation system. The femoral and tibial component positions were measured from the computed tomography data with a three-dimensional evaluation software. The relationship between the component positions and knee kinematics of the extent of internal tibial rotation, which may produce medial pivot motion during knee flexion, was analyzed with multiple regression analysis.

Results

The internal rotational position of the femoral component was associated with the extent of internal tibial rotation from knee extension to 90° flexion (p = 0.000747, 95% confidence interval [CI]: 0.357–1.247) and maximum flexion (p = 0.0000445, 95% CI: 0.655–1.699) at post-TKA. There was a positive correlation between the extent of internal tibial rotation from knee extension to flexion at post-TKA and the internal rotational position of the femoral component.

Conclusions

The internal rotational position of the femoral component can have a positive impact on knee kinematics.
