Abstract :

Background & Aim: Stair stepping motion and standing and sitting motion from a chair are important in daily living, similar to gait. It is important to understand in vivo kinematics of patientâ��s with total knee arthroplasty during stair-stepping and standing and sitting motion from chair. The purpose of this analysis was to estimate in vivo knee motion in stair stepping and standing and sitting motion from a chair, and determine if this unique knee prosthesis function as designed. Methods: A total of 20 patients implanted with Bi-Surface PS were assessed in stair-stepping. 15 patients were assessed in standing and sitting from chair. The Bi-surface PS knee is a posterior-cruciate substitute prosthesis with a unique ball-andsocket joint in the mid-posterior portion of the femoral and tibial components. Patients were examined during stair stepping and standing and sitting motion from a chair motion using a 2-dimensional to 3-dimensional registration technique. Results: In stair-stepping, the kinematic pattern in step up was a medial pivot, in which the level of antero-posterior translation was very small. In step down, the kinematic pattern was neither a pivot shift nor a rollback. From minimum to maximum flexion, anterior femoral translation occurred slightly. In standing and sitting from a chair, from minimum to 30�° knee flexion, anterior femoral translation occurred slightly. From 30�° knee flexion to maximum flexion, the kinematic pattern was a medial pivot and rollback. Conclusion: It became clear in this study that the jointâ��s stability during stair-stepping was affected by the design of the femorotibial joint rather than Post/Cam engagement or the Ball & Socket joint. In standing and sitting from a chair, the unique knee prosthesis functioned as designed.
