Osteoarthritis is a disabling condition globally, affecting a major population. The non-invasive conservative management of osteoarthritis is majorly catered to by physical therapy rehabilitation. Research has been conducted to evaluate the impact of the most commonly used electrotherapy modality, therapeutic ultrasound, on reducing pain and increasing functional activities in individuals suffering from osteoarthritis, but the condition is still, after over two decades of research, growing rapidly in its prevalence. Therefore, the aim of our study was to analyze the literature and compare the evolving trends in coupling medium used for the application of therapeutic ultrasound in arthritic conditions of musculoskeletal origin. Databases of PubMed, Web of Science, Embase, Pedro, and Cochrane were searched till June 2022. The outcome measures used were to detect the status of pain and improvement in functional status. Overall ultrasound therapy adjunct to exercise program was found to be superior to either ultrasound therapy or exercise program alone for the management of pain and functional status of the patients. Additionally, phonophoresis was deduced to have shown better pain relief than conventional ultrasound. Phonophoresis was done using non-steroidal anti-inflammatory drugs and Ayurvedic medicinal herbs in the form of Nano gel.
