Anterior referencing versus posterior referencing in total knee arthroplasty.
Appropriate femoral component positioning and sizing is essential for proper kinematic function in total knee arthroplasty (TKA). Anterior or posterior referencing (AR or PR) are two major techniques for setting center of rotation and for balancing the sagittal plane of the arthroplasty. Both techniques have advantages and disadvantages. Minimally invasive surgical (MIS) TKA has added yet anoth...
متن کاملSymptomatic flexion instability in posterior stabilized primary total knee arthroplasty.
Flexion instability in posterior-stabilized total knee arthroplasty is a relatively uncommon but distinct problem that is often underdiagnosed and may require surgical management. This retrospective study evaluated the authors' management strategy and assessed the results of revision surgery. The authors identified 19 knees that underwent revision for isolated flexion instability after primary ...
متن کاملFlexion and extension gap balancing in revision total knee arthroplasty.
UNLABELLED Revision total knee arthroplasty presents a unique set of problems when attempting to balance flexion and extension gaps. Loss of soft tissue support and established deformity can make balancing difficult. One needs to balance the flexion and extension gap heights as well as medial and lateral symmetry, which may not always be attainable. We used a set of stepwise techniques to reest...
متن کاملFlexion Gap Preparation Opens Both the Extension and Flexion Gap during Total Knee Arthroplasty
+Minoda Y, Iwaki H, Ikebuchi M, Yoshida T, Iida T, Ikawa T, Yamasaki S, Nakamura H. + Osaka City University Graduate School of Medicine, Osaka, Japan, [email protected] INTRODUCTION: Soft-tissue balancing of the knee is fundamental to the success of total knee arthroplasty (TKA). Preparing equal and rectangular extension and flexion joint gaps is the most important goal in TKA bec...
متن کاملKnee flexion after total knee arthroplasty.
PURPOSE To identify factors related to knee flexion after total knee arthroplasty in a Chinese population. METHODS Records of 242 total knee arthroplasties were retrospectively reviewed. The parameters evaluated were age, gender, diagnosis, preoperative knee flexion and extension, preoperative flexion arc, tibiofemoral angle, Knee Society knee score and functional score, and implant design. ...
