Abstract
Objective: To explore the application value of high-frequency ultrasound and contrast-enhanced ultrasound in different syndrome types of knee osteoarthritis, and to provide more imaging evidence for clinical diagnosis and treatment. Method: Sixty patients with KOA were selected according to TCM classification, which were mainly divided into Qi stagnation and blood stasis type and cold-dampness blockage type. All knee joints were routinely examined by high frequency ultrasound, and those with synovial hyperplasia were examined by contrast-enhanced ultrasound. High frequency ultrasound is the examination of synovium, cartilage and collateral ligament of knee joint based on two-dimensional ultrasound. Contrast-enhanced ultrasound (CEUS) refers to the contrast examination of synovium in knee joint patients with synovial hyperplasia. Result: Among them, the suprapatellar sac effusion and synovial thickening of Qi stagnation and blood stasis type were more obvious than those of cold-dampness arthralgia type (P 0.05). Conclusion: To a certain extent, the high-frequency ultrasound and contrast-enhanced ultrasound performance of knee osteoarthritis can be used as a dialectical reference for different TCM syndrome types.
Highlights
Knee Osteoarthritis (KOA) is due to a variety of reasons that cause cartilage degenerative damage in the human knee joint, osteophytes on the edges of the joints, and narrow knee joint gaps, and it can be accompanied by varying degrees of slippage
All knee joints were routinely examined by high frequency ultrasound, and those with synovial hyperplasia were examined by contrast-enhanced ultrasound
Diagnostic criteria of western medicine: diagnostic criteria of knee osteoarthritis formulated by American Rheumatology Society [4], diagnostic classification criteria of traditional Chinese medicine: refer to “Expert Diagnostic Consensus of Knee Osteoarthritis” “Therapeutics of Traditional Chinese Medicine” (2015 edition) [5], TCM syndrome differentiation belongs to Qi stagnation and blood stasis type and cold-dampness arthralgia type
Summary
Knee Osteoarthritis (KOA) is due to a variety of reasons that cause cartilage degenerative damage in the human knee joint, osteophytes on the edges of the joints, and narrow knee joint gaps, and it can be accompanied by varying degrees of slippage. Knee osteoarthritis is mainly caused by the opening of the skin and hair, and the invasion of wind, cold and dampness, causing the meridians to become disharmony, stagnation of Qi and blood stasis, and become bone arthritis [2]. This disease is mainly characterized by deficiency of vital energy and weakness.
