Physical therapy can be an effective treatment option for knee pain. The therapist will evaluate the patient's condition and create an individualized treatment plan that may include exercises to increase strength, flexibility, and range of motion in the knee. They may also use modalities such as ice or heat therapy, ultrasound, and electrical stimulation to reduce pain and inflammation. Other techniques such as massage and manual therapy may also be used. The goal is to improve the patient's function and reduce pain, allowing them to return to their normal activities.
