“…Postoperative PC at maximum extension was significantly higher, and postoperative PC at 90°was significantly lower compared to before surgery (*p<0.05). OA pre-operative data, MP postoperative data patellofemoral kinematics, especially in PC, and differed from those of previous reports on PS and cruciate-retaining design [10,11].…”

“…The flexion angle was measured on the X-ray images and was defined as the angle made by the longitudinal axes of the femur and tibial long bones [9]. Thereafter, patella flexion angle (PF), tibiopatellar angle (TP) and estimated patellofemoral contact point (PC) were evaluated, according to a previously reported method [10,11] (Fig. 1).…”

Purpose ADVANCE® Medial-Pivot (MP) (Wright Medical Technology, Arlington, TN, USA) total knee arthroplasty (TKA) was developed to replicate normal tibiofemoral knee joint kinematics, allowing medial-pivot knee motion. The design concept of the prosthesis is unique; therefore, the influence on the patellofemoral knee joint remains unclear at present. The purpose of this study was to determine the in vivo patellofemoral kinematics with ADVANCE® MP TKA and compare them with the pre-operative conditions.

“…Another important reason could be considered from the viewpoint of femoro-tibial kinematics and joint gap theory [30,35,36]. Komistek et al pointed out that femoro-tibial kinematics can play a major role in patellofemoral kinematics [37].…”

“…Generally, direct comparison of the postoperative prosthesis orientation with the conditions before operation is difficult. Although X-ray, CT and MRI as methods of evaluation have been assessed in many reports [29][30][31], there are some weaknesses in these methods. Although a 2D-3D registration technique, combined with fluoroscopic analysis, has been used to assess postoperative tibio-femoral joint kinematics with high accuracy [32], limitations remain for assessing the PF joint [33].…”

Purpose ADVANCE® Medial Pivot (MP) (Wright Medical) total knee arthroplasty (TKA) was established to replicate normal tibio-femoral knee joint kinematics, however, its influence on the patello-femoral (PF) joint is unclear. The purpose in this study was to assess the PF joint conditions in Advance MP TKA, via radiography and three-dimensional image-matching software. Methods Ten subjects with osteoarthritis were treated with the ADVANCE MP TKA. Pre-operatively and one month after surgery, skyline views at 30, 60, and 90°of flexion were taken, and patella shift and tilt were measured. With 2D-3D registration techniques using software, implant orientations were matched with the pre-operative CT and changes in the anterior part of the femoral prosthesis, condylar twist angle (CTA) for femoral rotation, and tibial rotation were evaluated. The relationships between morphological and rotational changes were evaluated. Results There were significant differences in patella tilt at 60°a nd patella shift at all angles between pre-and post-operation (p<0.05). No correlation was found between morphological changes in the anterior femur with patella tilt and shift. A positive correlation between postoperative CTA and patella shift at 90°was found (p<0.05); however, no correlation was found between rotational alignment of the tibial component and patella tilt and shift. Conclusions ADVANCE MP TKA changed patello-femoral joint kinematics, compared to that found before surgery. The kinematic features were mainly due to the design concepts for tibio-femoral joint motion, indicating the difficulty to reproduce normal patello-femoral joint kinematics after TKA.
