What this trial studies

This trial investigates the use of neuromuscular electrical stimulation (NMES) to enhance recovery and reduce quadriceps weakness in patients who have undergone total knee arthroplasty (TKA). The study will be conducted in two healthcare systems, UCHealth and Intermountain Health, involving outpatient physical therapy clinics. It aims to evaluate the effectiveness and feasibility of implementing NMES in real-world rehabilitation settings, where its use has been notably low despite its clinical recommendations. Participants will be randomly assigned to receive either NMES or usual care during their rehabilitation process.

Who should consider this trial

Good fit: Ideal candidates are patients who have undergone primary unilateral TKA and are able to start NMES within a week post-surgery.

Not a fit: Patients with contraindications for NMES, such as those with implanted cardiovascular devices or active cancer, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve functional recovery and strength in patients after knee surgery.

How similar studies have performed: While NMES has shown efficacy in controlled settings, its implementation in real-world clinical practice remains underexplored, making this approach novel.
