Objective: To investigate the effects of acupotomy on skeletal muscle fibrosis and collagen deposition in a rabbit knee osteoarthritis (KOA) model. Methods: Rabbits (n = 18) were randomly divided into control, KOA, and KOA + acupotomy (Apo) groups (n = 6). The rabbits in the KOA and Apo groups were modeled using the modified Videman's method for 6 weeks. After modeling, the Apo group was subjected to acupotomy once a week for 3 weeks on the vastus medialis, vastus lateralis, rectus femoris, biceps femoris, and anserine bursa tendons around the knee. The behavior of all animals was recorded, rectus femoris tissue was obtained, and histomorphological changes were observed using Masson staining and transmission electron microscopy. The expression of transforming growth factor-β1 (TGF-β1), Smad 3, Smad 7, fibrillar collagen types I (Col-I) and III (Col-III) was detected using Western blot and real-time polymerase chain reaction (RT-PCR). Results: Histological analysis revealed that acupotomy improved the microstructure and reduced the collagen volume fraction of rectus femoris, compared with the KOA group (P = .034). Acupotomy inhibited abnormal collagen deposition by modulating the expression of fibrosis-related proteins and mRNA, thus preventing skeletal muscle fibrosis. Western blot and RT-PCR analysis revealed that in the Apo group, Col-I, and Col-III protein levels were significantly lower than those in the KOA group (both P

Objective: To investigate whether acupotomy could inhibit subchondral bone remodeling in knee osteoarthritis (KOA) rabbits by regulating the activity of osteoblasts and osteoclasts. Methods: KOA rabbits were prepared by immobilization for 6 and 9 weeks by Videman method. Nine groups of rabbits (control, 6 weeks and 9 weeks model, 6 weeks and 9 weeks acupotomy, 6 weeks and 9 weeks electroacupuncture, and 6 weeks and 9 weeks drug groups) received acupotomy, electroacupuncture and risedronate sodium intervention, respectively, for 3 weeks. Results: Acupotomy can inhibit the activity of osteoclasts and osteoblasts in subchondral bone by reducing the proteins expression of cathepsin K (CK) and tartrate-resistant acid phosphatase (TRAP) and decreasing the proteins expression of osteocalcin (OCN) and alkaline phosphatase (ALP), to intercept the abnormal bone resorption and bone formation of subchondral bone in 6-week and 9-week immobilization-induced KOA rabbits. Conclusion: These findings indicated that acupotomy may be more advantageous than risedronate sodium intervention in modulating subchondral bone remodeling in KOA rabbits, especially in 9-week immobilization-induced KOA rabbits.

Background Compared with conventional closed therapy, acupotomy has the advantages of lower cost, convenient application, and better single and long-term effects. The aim of this study was to explore the clinical effect of acupotomy in the treatment of Tarsal Tunnel syndrome. Methods There were 80 patients enrolled into the study who were randomly assigned to either the acupotomy or closed therapy group, with 40 patients in each group. The acupotomy group was treated once every 6 days, on 3 occasions for the duration of treatment, and the closed therapy group was treated twice a week, for 3 weeks as the course of treatment. The effects of treatment were analyzed and evaluated according to the standard of curative effect. Results The “cure rate” of the number of patients in the acupotomy group whose symptoms had completely disappeared (13 patient out of 39) was higher than the closed therapy group (1 patient out of 39), and this difference was significant (p < 0.01). The number of patients in the acupotomy group who did not benefit from the therapy (5 patients) was significantly lower than the closed therapy group (15 patients; p < 0.05). The total number of patients in the acupotomy group who benefitted from the therapy (34 patients) resulted in an effective rate of 87.18%, which was higher than the closed therapy group (24 patients; 61.53%). The difference was statistically significant (p < 0.05). Conclusion Acupotomy is effective in the treatment of Tarsal Tunnel syndrome, was superior to traditional closed therapy, and is worthy of clinical application.
