Also, the technique used here, in addition to version, allowed the measurement of inclination, rotation, and antero-posterior offset distance.
4 parameters of the preoperative glenoid position and of the glenoid implant position were investigated: version, inclination, rotation, and the anterior-posterior offset distance of the glenoid relative to the plane of the scapula.
Posterior condylar offset (PCO) and posterior tibial slope (PTS) have critical consequences in total knee arthroplasty, especially with regards to sagittal plane balancing.
Component design modifications focus on lengthening the radius of curvature through the posterior condyles, increasing the posterior condylar offset, recessing the tibial insert, lengthening the trochlear groove, and altering the cam-post design.
In addition, patients' subjectively preferred sides were noted, and radiologic results based on implant positions, posterior offsets, anterior offsets, and patellofemoral alignments were evaluated.
To study whether the range of knee flexion (ROF) is affected by geometrical mismatch of the femoral component and the resultant change in the posterior condylar offset (PCO) after high-flexion posterior-stabilized total knee arthroplasty (TKA).
Posterior condylar offset (PCO) has important implications in total knee arthroplasty (TKA) function and design.
This, however, leads to a smaller posterior condylar offset, which is inappropriate for good knee flexion.
In fact, Bellemans et al. reported that the posterior condylar offset decreased by 2 mm, and that maximal obtainable flexion was reduced by a mean of 12.2° [ 22].
