Patients experience dramatic quadriceps strength loss after total knee replacement, which contributes to persistent weakness and reduced long-term function after surgery. Neuromuscular electrical stimulation (NMES) reduces quadriceps weakness and improves patient function after knee replacement, but it is drastically underused in rehabilitation practice. This randomized trial will examine the effectiveness and feasibility of a comprehensive strategy for implementing neuromuscular electrical stimulation after knee replacement in two large healthcare organizations.
