Rebuild the knee,
don’t replace it.
Osteoarthritis has no cure. Yet.
It wears away the cartilage that cushions our joints, and with it, the everyday movements we take for granted. Today, patients choose between short-lived pain relief and joint replacement surgery. In between, there is nothing.

One injection. Three stages of care.
SYNARCH is an injectable hydrogel that the orthopedic surgeon applies in the clinic, with no operating room. It is designed to keep working long after the injection.




Relieve, Days
Lubricates the joint and eases pain, because patients need to feel better now.

Reduce inflammation, Weeks
Releases its therapy steadily, right where the damage is, to slow cartilage breakdown.

Regenerate, Months
Helps the joint’s own cells produce new cartilage again.
- Outpatient procedure
- No surgery
- Followed up with ultrasound in the clinic
Remains. Rejuvenates. Rebuilds.
Most knee injections wash out of the joint within hours or days. SYNARCH is a hydrogel built to stay and work where it is needed.
