Best Practice Case Studies-CPPD Knee Joint Effusion

Video Transcription

Video Summary

Lauren Rudolph provides an ultrasound consultation for a knee joint effusion linked with calcium pyrophosphate dihydrate (CPPD) deposition disease. The ultrasound revealed a significant effusion with CPPD-related hyperechoic crystals in the right knee, unlike the unaffected left knee. Key ultrasound features include sparkling deposits in the synovial fluid and meniscal calcifications visible in different knee views. Distinct from gout's double contour sign, CPPD shows hyperechogenicity within the cartilage. While ultrasound aids CPPD diagnosis, arthrocentesis with crystal analysis remains the gold standard per the 2023 classification criteria by the American College of Rheumatology.
