Activity Description

Spontaneous osteonecrosis of the knee primarily affects the subchondral bone of the medial femoral condyles due to weight-bearing stress, and involvement of the lateral femoral condyles and tibial plateau is less common. This condition is characterized by distinctive crescent-shaped osteonecrosis lesions, often leading to sudden, intense knee pain, swelling, functional impairment, and the risk of joint deterioration. Spontaneous osteonecrosis of the knee predominantly affects middle-aged individuals aged 55 or older, suggesting a potential association with postmenopausal osteoporosis.

Spontaneous osteonecrosis of the knee can progress rapidly, potentially resulting in subchondral collapse, secondary osteoarthritis, and necessitating surgical intervention. This condition's precise cause remains unclear, posing a diagnostic and therapeutic challenge due to its nonspecific symptoms and gradual onset. Diagnosis relies on clinical presentation and magnetic resonance imaging findings, while treatment is individualized based on lesion size and stage to preserve joint function whenever feasible. Gaining a deeper understanding of the condition's etiology, alongside advancements in diagnostic and therapeutic approaches, is crucial for shedding light on this complex condition. This activity emphasizes the etiology, evaluation, management, and complications of spontaneous osteonecrosis of the knee, focusing on diagnostic nuances, contemporary treatment modalities, and nonoperative measures as the primary treatment approach. This activity also highlights the critical roles of interprofessional healthcare teams in enhancing their competence in diagnosing and treating this condition, ultimately contributing to improved patient outcomes and quality of life.
