Extracorporeal Shockwave Versus Phonophoresis Using Chitosan-Nanoparticles Gel on Functional and Anatomical Changes Detected With Artificial Intelligence Based Texture Analysis Algorithm in Knee Osteoarthritis Patients: A Double Blind Randomized Controlled Trial

A parallel double blinded randomized controlled clinical trial (RCT) with a 1:1:1 allocation will be conducted in an orthopedic clinic in Cairo and Giza Governments - Egypt. This RCT will evaluate the pain reduction, self-reported functional improvement, physical functional and anatomical improvement following the application of phonophoresis using chitosan-nanoparticles gel, ECSW therapy and traditional exercises compared to each other. The treatment period will last for 4 weeks with a total of (12 sessions/ 3 sessions per week for the application of phonophoresis using chitosan-nanoparticles gel and traditional exercises program) and (5 sessions/ 1 every week for the application of ECSWT). The participants will be assessed at two different time-points (before-after treatment) with a sample size of 40 patients in each group (3 groups)
