Conventional pain treatments have been very good at reducing pain by masking discomfort in a “band aid” fashion with oral or injected medications like steroids, narcotics,  or NSAIDs. These therapies unfortunately do not fix the underlying problem.

Fixing Tissue Injury

So how is the condition actually repaired, whether it’s shoulder/knee/hip/ankle arthritis, back or neck pain, golfer’s or tennis elbow, rotator cuff tendonitis or a ligament injury?

Regenerative Medicine has the potential to restore anatomy  with stem cells, growth factors and platelets to facilitate a healing response in one’s own body.

Stem Cells are like a blank slate and may differentiate into any number of cell types for tissue regeneration. This is in large part dependent on the environment in which they are placed.

Chicago Stem Cell Procedures

Stem cell injection treatments include:Platelet Rich Plasma Therapy Research

These are all minimally invasive, same day, low risk, outpatient procedures.

Initial studies are showing these stem cell therapies to offer substantial promise in healing injury while reducing pain. For example, most professional sports leagues have approved of PRP therapy along with the World Anti-Doping Association.

Pro athletes who have received regenerative medicine treatment include the likes of Rafael Nadal, Dwight Howard, Tiger Woods, Kobe Bryant, Bartolo Colon and many more.

The treatments are also producing exceptional outcomes for degenerative arthritis, COPD, kidney failure, neuropathy, Lyme disease, heart failure and more.

All of the treatments are performed by highly experienced providers.
