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…
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…
Soft Tissue Balance of the Native Knee Provides Guidance for Balancing a Total Knee Arthroplasty
Fig. 2.1 Renderings of bone models of the femur, tibia, and fibula show how the varus laxity of the knee is determined. The other six laxities are determined in a…
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…
