Knee osteoarthritis pain, stiffness, and edoema can all be relieved with physical therapy, as well as improved knee joint function. Walking, bending, kneeling, crouching, and sitting can all be made simpler with it. Passive and active therapies are the two major types of physical therapy that might help you manage your knee OA. Forth passive treatments, the physical therapist puts in the majority of the effort. Active treatments, on the other hand, require you to do more of the effort, such as at-home exercises.
