The invention provides an electronic arthroscope with an adjustable imaging angle. The electronic arthroscope comprises an endoscope image control box, an image monitor and an endoscopic module, the endoscopic module is in data transmission with the endoscope image control box, and the endoscope image control box is in data transmission with the image monitor; image data acquired by the endoscopic module is processed by the endoscope image control box and then is visually displayed through the image monitor; the endoscopic module comprises a lens assembly, a lens barrel and an adjusting assembly. The imaging angle can be conveniently adjusted, multi-angle observation of the focus position can be achieved, and the problem that a traditional arthroscope is single in visual angle is solved. Compared with a traditional arthroscope, the arthroscope has the advantages that the cost is greatly reduced, the arthroscope can serve as a disposable consumable, disinfection is not needed, the risk of infection caused by incomplete disinfection of the traditional arthroscope is avoided, disinfection and sterilization are not needed before each operation, and the operation preparation time is greatly shortened.
