Methods and devices are provided for OA treatment of an affected area or joint. In one embodiment, the method may involve identifying a treatment site of the joint, and providing at least one transducer module at the treatment site. The at least one transducer module may be in operative communication with a signal generator module, and may include transducer(s) for delivering ultrasound signals. The method may also involve stimulating (a) bone remodeling, (b) bone cells and associated precursors, and/or (c) pericytes with the electromagnetic signals delivered to the treatment site at a user-selected intensity.
