Patients with septic knee arthritis tend to have prolonged pain, which may lead to a decrease in physical activity (PA). Pain catastrophizing, which is associated with chronic pain, is known to be a limiting factor for PA. An objective measurement of PA in patients with septic knee arthritis has not been reported. Here we describe the accelerometry-based measurement of the PA of a patient with septic knee arthritis before and after discharge, and we report the ability of follow-up outpatient physical therapy to increase PA.
