Osgood-Schlatter disease, or apophysitis of the tibial tubercle, is a common orthopedic condition seen in children between 10 and 15 years of age. The disease is caused by the repetitive application of mechanical forces on the knee, leading to microtrauma on the ossification Ossification The process of bone formation. Histogenesis of bone including ossification. Bones: Development and Ossification center at the site of insertion of the distal patellar ligament. Patients Patients Individuals participating in the health care system for the purpose of receiving therapeutic, diagnostic, or preventive procedures. Clinician–Patient Relationship present with localized knee pain Knee Pain Knee pain is a common presentation to primary care physicians. The diagnosis can be challenging as the pain may arise from the joint, surrounding tissues, or referred to the joint from distant structures. The differential diagnosis of knee pain is broad and categorizing the various diagnoses related to the timing (acute or chronic) is useful. Knee Pain, tenderness, and swelling Swelling Inflammation at the proximal anterior tibia Tibia The second longest bone of the skeleton. It is located on the medial side of the lower leg, articulating with the fibula laterally, the talus distally, and the femur proximally. Knee Joint: Anatomy. Diagnosis is clinical and treatment is focused on symptomatic relief. Osgood-Schlatter disease is a self-limiting Self-Limiting Meningitis in Children condition that resolves with skeletal maturity.

Osgood-Schlatter disease is an apophysitis, a painful traction injury, of the cartilage Cartilage Cartilage is a type of connective tissue derived from embryonic mesenchyme that is responsible for structural support, resilience, and the smoothness of physical actions. Perichondrium (connective tissue membrane surrounding cartilage) compensates for the absence of vasculature in cartilage by providing nutrition and support. Cartilage: Histology and bone Bone Bone is a compact type of hardened connective tissue composed of bone cells, membranes, an extracellular mineralized matrix, and central bone marrow. The 2 primary types of bone are compact and spongy. Bones: Structure and Types on the anterior, proximal tibial tubercle, where the distal patella Patella The flat, triangular bone situated at the anterior part of the knee. Knee Joint: Anatomy tendon inserts.
Osgood-Schlatter disease: a painful inflammation Inflammation Inflammation is a complex set of responses to infection and injury involving leukocytes as the principal cellular mediators in the body’s defense against pathogenic organisms. Inflammation is also seen as a response to tissue injury in the process of wound healing. The 5 cardinal signs of inflammation are pain, heat, redness, swelling, and loss of function.
