Background: The study aim was to determine the effect of low intensity pulsed ultrasound therapy to reduce the effusion volumes and pain in patients with Knee OA.

Methods: This study design was randomized controlled trial. Total 50 patients diagnosed with Knee osteoarthritis were randomly assigned to two groups. Group I was using treatment of low intensity pulsed ultrasound therapy and group II was administered TENS with home exercise respectively. Treatments were 6 days per week and duration of 2 week. The amount of effusion volume will be measured via ultrasonograpy in knee.

Results: The maximum number of cases are lying in age group >60 years which is 28% and 40% in cases and control group respectively and age distribution in both the group is statistically not significant. The mean age of patients in cases and control group is 57.08±7.40 years and 58.04±9.93 years respectively.

Conclusions: Low intensity pulsed ultrasound therapy significantly reduced the effusion volumes and pain in patients with knee osteoarthritis.
