Knee Ultrasound: Articular Cartilage Pathologies (Chondromalacia, OCD, Chondrocalcinosis)

This video demonstrates ultrasound evaluation of articular cartilage pathology in the knee joint, including: Chondromalacia (Grades I to IV) Chondrocalcinosis Osteochondritis dissecans (OCD) Advanced degenerative cartilage loss Subchondral bone irregularity Indirect ultrasound signs of osteoarthritis The examination is performed using high-frequency musculoskeletal ultrasound in routine orthopedic clinical practice. Ultrasound allows dynamic, real-time assessment of femoral condylar cartilage, trochlear groove cartilage, and weight-bearing surfaces of the knee. Proper probe alignment and recognition of anisotropy artifacts are essential for accurate interpretation. What is shown in this video? Normal cartilage appearance in adult and pediatric knees Cartilage thickness assessment, approximately 2 millimeters in adults Grade I chondromalacia - softening, thickening, increased echogenicity Grade II - partial-thickness defects less than 50 percent Grade III - cartilage thinning greater than 50 percent Grade IV - complete cartilage loss with subchondral irregularity Osteophyte formation in advanced osteoarthritis Chondrocalcinosis - intracartilaginous calcifications Osteochondritis dissecans (OCD) in longitudinal and transverse planes This presentation emphasizes ultrasound pattern recognition, clinical correlation, and practical diagnostic pitfalls. Osteochondritis Dissecans (OCD) - Scientific Background OCD predominantly affects the medial femoral condyle and is frequently observed in young athletes. Early detection is essential to prevent progression to osteoarthritis.
