Kinematics of the Normal Native Knee
(1) Ghent University, Ghent, Belgium 3.1 Introduction ‘Kinematics’ is a term often used in orthopaedics, unfortunately not always in the correct sense of the word. The term ‘kinematics’ is…
Assessment in Primary TKA: Intraoperative Assessment Tensor
Fig. 13.1 Offset-type tensor. The tensor consists of three parts: upper seesaw plate, lower platform plate, and extra-articular main body. Two plates are connected to the extra-articular main body by…
Intraoperative Assessment with Computer Navigation
Fig. 14.1 Limb is held by the foot and elevated. There is a 1° flexion contracture with optimal alignment. Note the limb appears fully extended Figs. 14.2 and 14.3 Surgeon…
Operative Procedure: Varus Knee
Fig. 9.1 Sacrificing the posterior cruciate ligament in a PS total knee replacement 9.3 Step 2: Osteophytes The presence of osteophytes on the medial aspect of the tibial plateau and…
Intraoperative Soft-Tissue Balance and Clinical Results (ROM, Function)
Fig. 16.1 Offset-type sensor used in total knee arthroplasty, which enables soft-tissue balance assessment. Left; Fuzion (Zimmer, Warsaw, USA), Right; Attune (Depuy Synthes, Warsaw, USA) Despite advanced accuracy in bony…
PS: Gap Technique
Fig. 6.1 If the knee joint is well tensioned in flexion, anterior and posterior femoral resections are made by using an AP cutting block Fig. 6.2 Spacer blocks can be…
Soft Tissue Balance, Kinematics, and Patient Satisfaction
Fig. 17.1 Factors affecting clinical results after total knee arthroplasty In this chapter, clinical and biomechanical studies are introduced to discuss the relationship among soft tissue balance, kinematics, and clinical…
Bicruciate-Retaining TKA: How to Achieve Near-Normal Kinematics
Fig. 7.1 The Gunston polycentric knee (From Gunston [22]) The 1970s saw the introduction of several BCR TKAs. The Coventry Geomedic knee consisted of a single femoral component with a…
Anatomy and Biomechanics of the Native Knee and Its Relevance for Total Knee Replacement
Fig. 1.1 (a) Anterior view of a right cadaveric knee demonstrating the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), and lateral meniscal anterior root attachment (LARA). (b) Sagittal cross…
Primary Principles in Soft Tissue Balancing
Fig. 4.1 Rectangular (a) extension gap and (b) flexion gap The resections of the tibia and femur during knee arthroplasty must result in rectangular flexion and extension gaps (equal medial…
