Experience the future of sports medicine at RSI.

The Regenerative SportsCare Institute (RSI) is changing the game in musculoskeletal care. Combine powerful regenerative procedures with in-house imaging and pioneering physicians, and you have RSI—Manhattan’s premier outpatient center for non-surgical, interventional orthopedic care.

Our mission is simple:

To place the needs of the patient above all others.

Welcome to RSI
Our approach:

Help the body heal itself.

We believe the human body contains the most powerful medicine available for patients suffering from acute and chronic musculoskeletal pain: platelets and bone marrow-derived mesenchymal stem cells.

By harvesting, concentrating, and injecting our patients’ own cells directly into the site of the injury under fluoroscopic or ultrasound guidance, we enhance the body‘s innate self-healing mechanisms. Platelet-rich plasma (PRP) and stem cell therapies tap into the same regenerative process that heals a scraped knee or a cut finger—we just take that process deeper inside the body and accelerate it. In essence, we harness nature’s most potent healing forces and deliver them to where they are most effective, promoting faster and longer-lasting repair.

Our patients say it best.

More Efficient. More Personal. Better Outcomes.

We feel that patients should not have to wait days and weeks to coordinate MRI appointments with physician consultations and treatment. So we built RSI to accommodate consultations, imaging, and procedures all at the same site, enabling us to diagnose and treat many of our patients in the same day. In other words, we’ve got your back… and your knee, hip, shoulder, ankle, and elbow.
