Evaluation of the Therapeutic Effect of Contrast-Enhanced Ultrasound on Different Types of Knee Osteoarthritis in the Elderly

Objective: To evaluate the curative effect of Traditional Chinese Medicine (TCM) external therapy on knee osteoarthritis patients with different TCM constitutions using musculoskeletal ultrasonography and contrast-enhanced ultrasonography, to explore application value in joint diseases. Methods: A total 57 diagnosed Shaanxi University from December 2019 May 2021 were collected, they divided into qi stagnation blood stasis type group (23 cases) cold-dampness obstruction (34 according traditional medicine method. All given acupuncture combined fumigation washing. underwent before after treatment, observed recorded relevant data, compared treatment effects between two groups. Results: 85.96% (49/57) (KOA) had suprapatellar bursa effusion, 42.1% (24/57) iliotibial band bursae some which poor sound transmission, thickened synovium was seen most effusions, 33.33% (19/57) osteophyte formation. Compared depth sac effusion Qi decreased (P < 0.05). The protrusion height 0.05), infrapatellar prefermoral fat pad thickness increased synovial membrane KOA showed degrees uniform enhancement, showing slow out. surrounding soft tissue, arterial phase equal enhancement. enhanced a clear boundary effusion. In venous phase, intensity gradually until clearing. there no significant difference ultrasound parameters Conclusion: Musculoskeletal used quantitatively efficacy for constitutions. Dynamic observation lesions provides valuable imaging method evaluating medicine.
