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…
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…
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…
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…
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…
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…
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…
Fig. 29.1 Sagittal T1 MRI showing tendon thickening and an abnormal signal at the proximal insertion of the patellar tendon Fig. 29.2 Sagittal T1 MRI showing a marked tendon thickening…
Fig. 8.1 Dynamic MRI scan acquired at the level of the arm during flexion/extension The dynamic investigation arises as very useful during ongoing muscle injuries with large hematomas, which at…
Fig. 7.1 Fusion technology is extremely useful, especially in following up lesions, since the overlay of the initial US and MRI scans enables superimposition of further scans and demonstration of…
