Introduction Materials science and 3D printing As discussed in Chapter 1 , materials for 3D printing include polymers, ceramics, metals, and composites. The materials used to fabricate a 3D part are dependent on the performance, or the “requirements” of the…
Introduction To design implants that are personalized to the patient’s anatomy and a specific surgical plan, engineers rely on medical imaging to create accurate anatomical reconstructions. CT image data is commonly required in orthopedic applications due to the volumetric dataset…
Introduction 3D printing has changed the landscape of medical devices by accelerating innovation and expanding what is possible to make. Ideas that used to be too expensive or not possible can now be easily 3D printed. Today 3D printing is…
Introduction New biologic options are being developed throughout the world to enhance existing techniques, offer new off-the-shelf options, and provide reproducible structural repair. I contacted several companies worldwide and asked them to share their core technologies, preclinical development, clinical trial…
My residents and clinical fellows have often asked me where they can find a well written technique for a medial subvastus exposure as well as the tips and tricks that I use in more complex joint-preserving reconstructions. For this reason…
Introduction Loss of meniscal tissue drastically alters the biomechanical environment of the knee joint, especially in the lateral compartment, where contact stress can increase by 200% to 300% after total meniscectomy. Compartment overload syndrome can ensue, presenting with weight-bearing pain…
Introduction The management of an osteochondral defect in the knee is one of the most difficult conditions for the orthopedist. Although a fresh osteochondral allograft seems to be the treatment of choice for this condition, allografts are not without their…
Introduction This chapter is meant to offer the practicing orthopedist a practical management approach to dealing with patellofemoral disease. The key to successful treatment relies on an accurate diagnosis of the underlying pathomechanics responsible for the pain. Chronic patellofemoral pain…
Introduction The valgus knee (see Fig. 11.1 ) is usually associated with hypoplasia of the lateral femoral condyle and a superior lateral directed joint line. The ankle joint is frequently obliquely orientated to the floor parallel to the knee joint…
Arthritis and Malalignment The premise of knee osteotomy surgery is to correct malalignment at the site of the deformity and relieve pressure on the overloaded or arthritic compartment. In general, medial compartment osteoarthritis of the knee coexists with a varus…
