Imaging of Osteochondritis Dissecans
Osteochondritis dissecans (OCD) is a localized process that affects the subchondral bone and can progress to the overlying articular cartilage. The cause of this lesion remains elusive. With the vague…
ORTHOPEDIC
Acute Traumatic and Sports-Related Osteochondral Injury of the Pediatric Knee
Adolescents are predisposed to osteochondral (OC) injuries in the knee. The medial facet of the patella, the femoral trochlea, and the lateral femoral condyle are the most common sites of…
Effect of Exercise on Articular Cartilage
This review primarily focuses on how the macromolecular composition and architecture of articular cartilage and its unique biomechanical properties play a pivotal role in the ability of articular cartilage to…
Articular Cartilage Development: A Molecular Perspective
In this article, development of articular cartilage and endochondral ossification is reviewed, from the perspective of both morphologic aspects of histogenesis and molecular biology, particularly with respect to key signaling…
Structural and Functional Maturation of Distal Femoral Cartilage and Bone During Postnatal Development and Growth in Humans and Mice
The size and shape of joints markedly affect their biomechanical properties, but the macroscopic 3-dimensional (3-D) mechanism and extent of cartilage and joint maturation during normal growth are largely unknown….
Technical Considerations in Total Hip Arthroplasty After Femoral and Periacetabular Osteotomies
The purpose of this article is to outline key technical considerations in the performance of total hip arthroplasty after common osteotomies of both the proximal femur and acetabulum. Attention is…
Femoral Considerations for Total Hip Replacement in Hip Dysplasia
Hip dysplasia usually has associated femoral bone deformity. When total hip arthroplasty is considered, femoral bone deformity mandates special considerations in femoral reconstruction. The common deformities in the dysplastic femur…
Bearing Surface Considerations for Total Hip Arthroplasty in Young Patients
Bearing selection for total hip arthroplasty in young patients is important because of the likely long service life of the implant. Careful consideration of the next operation is recommended when…
Total Hip Arthroplasty and Hip Resurfacing Arthroplasty in the Very Young Patient
At present, hip arthroplasty is one of the most successful medical procedures available to the world, in terms of pain relief, return to function, and improvement in the quality of…
Imaging Hip Dysplasia in the Skeletally Mature
This article is an overview of diagnostic imaging for skeletally mature patients who present with hip pain. It discusses preferred radiographic views to assess acetabular dysplasia and femoroacetabular impingement and…
