What this trial studies

This observational study investigates the effectiveness of I-ONE therapy, a biophysical stimulation treatment, in reducing pain and inflammation in patients who have undergone total knee arthroplasty (TKA). It focuses on patients experiencing significant knee pain and swelling between 30 to 180 days post-surgery. The study aims to evaluate how I-ONE therapy can modulate inflammatory responses and improve functional recovery by targeting pro-inflammatory cytokines in the synovial fluid. By analyzing the relationship between inflammation and recovery, the study seeks to provide insights into new therapeutic strategies for post-operative care.

Who should consider this trial

Good fit: Ideal candidates are individuals who have undergone total knee replacement surgery and are experiencing moderate to severe pain without any signs of infection.

Not a fit: Patients with pain due to mechanical issues, previous knee infections, or systemic inflammatory diseases may not benefit from this therapy.

Why it matters

Potential benefit: If successful, this therapy could significantly reduce chronic pain and improve functional recovery for patients after knee replacement surgery.

How similar studies have performed: While the specific application of I-ONE therapy is novel, similar biophysical stimulation approaches have shown promise in managing post-surgical inflammation and pain.
