Thread-Embedding Therapy for Knee Osteoarthritis

Abstract

The aim of this study was to investigate the efficacy of thread-embedding therapy for the treatment of knee osteoarthritis. There were 20 patients treated with thread-embedding therapy at various acupoints on the muscles around the knee. Gender, age, location, morbidity period, numeric rating scale (NRS), Western Ontario and McMaster Universities (WOMAC) index, improvement result, side effects, and patient’s satisfaction were investigated. After the treatment, the NRS score (z = -4.07, <i>p</i> < 0.001) and WOMAC (<i>p</i> < 0.001) indices decreased in most patients. The NRS score decreased by more than 2 points in 95% of the patients. The WOMAC index decreased by 6-12 points. There were no serious side effects, although bruising, pain, and edema were observed. Overall, 85% of the patients felt satisfied with the thread-embedding therapy. These findings suggested that threadembedding therapy was effective and may be used widely for knee osteoarthritis.
