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…
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…
Surgical Treatment of Patellar Tendinopathy
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…
Ultrasound of Muscle and Tendon Pathology
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…
The Dynamic Magnetic Resonance Imaging
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…
Hand and Wrist Tendinopathies
