[Internal heat acupuncture therapy for 44 cases knee osteoarthritis of early to middle stages].

Objective: To observe the clinical effect of internal heat acupuncture therapy for knee osteoarthritis of early to middle stages, and explore its influence on cartilage thickness.

Methods: A total of 44 patients with knee osteoarthritis of early to middle stages were treated with internal heat acupuncture therapy at points (most of them are located at the subpatellar fat pad, both sides of the patellar ligament, the tendon of the quadriceps and the attachment of the medial and lateral collateral ligaments), once a week, a total of 4 weeks of treatment. Before and after treatment, after 3 months of treatment completion (in the follow-up), the visual analogue scale (VAS) score, Western Ontario and McMaster Universities osteoarthritis index (WOMAC) score, frequency of 30-second chair stand test (30sCST), cartilage thickness of femoral intercondylar and knee joint ultrasound score were compared, and the clinical effect was evaluated.

Results: After treatment, the VAS、WOMAC and knee joint ultrasound scores were reduced (<0.05), frequency of 30sCST was increased (<0.05) compared with those before treatment; in the follow-up, the VAS、WOMAC scores were reduced (<0.05), frequency of 30sCST and cartilage thickness of femoral intercondylar were increased (<0.05) compared with those before treatment. After treatment, the total effective rate was 93.2% (41/44), in the follow-up, the total effective rate was 95.5% (42/44).

Conclusion: Internal heat acupuncture therapy is effective in the treatment of knee osteoarthritis of early to middle stages, could relieve the pain, improve the joint function, and delay cartilage degeneration and disease progression.
