AIM: To observe the interventional effect of needle knife therapy combined with rehabilitative training on osteoarthritis of the knee, and to compare it with the effect of needle knife therapy alone. METHODS: Fifty-two patients with osteoarthritis of the knee admitted in Department of Rehabilitation Medicine, Naval General Hospital of Chinese PLA were selected from January 2005 to May 2007. They all voluntarily participated the study. All the subjects were randomized into control group (n = 24), and rehabilitation group (n = 29). Patients in the control group underwent needle knife therapy and medication. Patients in the rehabilitation group received needle knife therapy and rehabilitation training including straight-leg raising, flexion and extension of hip and knee, and straight-leg at sitting position. Besides the three basic actions, they also did some resistance exercise, and the amount and duration of exercise were increased gradually. Before treatment, the maximal heart rate of patients was measured to evaluate their heart function, and the systematic and concrete rehabilitation exercise prescription was designed. The exercise was done 60 minutes, once daily, 5 times a week for 6 weeks in 3 stages. The affected knee joint symptoms and functional recovery such as pain, walking ability, joint range of motion, knee instability, swelling, stair activity and twist were evaluated after 3 courses of treatment. RESULTS: Fifty-two patients were included in the final analysis. In the control group, the pain, walking ability, joint range of motion, knee instability, and stair activity of patients were improved after 3 courses of treatment, but swelling and twist did not significantly change (p > 0.05). In the rehabilitation group, all the symptoms and functions were improved significantly after 3 courses of treatment (p < 0.01) except twist. There were significant differences in the improvement in the symptoms and function of knee (except twist) between two groups (p < 0.05). CONCLUSION: Needle knife therapy in combination with rehabilitation training significantly improves the knee function in patients with osteoarthritis of the knee, which is superior to needle knife therapy alone.
