Based on the Ultrasound Evaluating the Effect of Xiaozhong Fang Particles for Knee Osteoarthritic With Synovial Fluid

Study Overview
=================
Brief Summary
-----------------
This study is a randomized, single blind, controlled trial. Aim to compare the effectiveness (especially the absorption degree of the synovial effusion measured by B ultrasonic) of the treatment group with the control group. The treatment group was given Xiao zhong fang granules orally and short wave infrared radiation and the control group was given the placebo Xiao zhong fang granules orally and short wave infrared radiation. To evaluate the clinical efficacy of the Chinese medicine in the treatment of the synovial effusion of knee osteoarthritis.
