Total knee arthroplasty (TKA) has evolved to be a very successful and reliable procedure reducing pain because of osteoarthritis, correcting deformities, and improving disability associated with other pathologic knee conditions. The excellent outcomes of TKA, strong marketing by implant companies…
What Is Mathematical Modeling? Mathematical modeling pertains to any simulation of a physical system using a computer. In practice, mathematical modeling is an extremely diverse field, which can be applied to any system, ranging from modeling weather patterns to analyzing…
The patellofemoral joint is an integral aspect of the knee that enhances flexion and extension. Any disturbance in the joint, such as injury, muscle weakness, and congenital or developmental abnormalities, can greatly affect the overall functionality of the joint and…
Analysis Methods The ongoing goal of improving the outcomes of total knee arthroplasty (TKA) yields the continuing need for accurate in vivo kinematic analyses. Popular kinematic study techniques include in vivo fluoroscopic analyses, in vitro analyses using cadavers, noninvasive analyses…
Introduction Of primary interest to the author of this chapter is the analysis of the intrinsic shape differences of the knee joint between different ethnic populations for development of implantable orthopedic devices. The research presented is thus threefold: by developing…
Introduction The use of ultrasound guidance for knee procedures has become increasingly popular in recent years due to recognized increased accuracy compared with those performed blind, as well as an expansion in the range of both intra-articular and extra-articular knee…
Introduction Tumors involving the knee can be subdivided into osseous and soft tissue neoplasms, with either benign or malignant histology. This chapter describes the patient demographics and multimodality imaging characteristics of the most common tumors about the knee, organized by…
Total knee arthroplasty (TKA) results in improvement in overall quality of life in more than 90% of patients. This remarkable success and factors such as an aging population have led to a dramatic increase in the number of procedures performed…
Imaging of the Extensor Mechanism The extensor mechanism of the knee plays an important role in normal lower extremity function. It is a complex of interconnected structures in the anterior knee that includes the quadriceps muscle group, quadriceps tendon, patella,…
Introduction The posteromedial corner of the knee (PMC) is a significant anatomic structure that is as important as the posterolateral corner in multiligamentous injuries. Even though it is easily seen on modern high-field magnetic resonance (MR) imaging systems, it is…
