Your Alternative to Knee Surgery

Have you been told that steroid injections or invasive surgery are your only options to treat your knee pain? Interventional orthopedics provides a non-surgical alternative that uses your own cells to repair the damage.

Recent research shows that some of the most popular orthopedic knee surgeries including meniscectomies have no benefit and are not more effective than placebo or sham surgery. Moreover, knee replacement is extremely traumatic and carries associated risks, and even successful surgeries minimally require months of painful rehab to regain strength and mobility. Most surgeries also accelerate degeneration that leads to osteoarthritis and exacerbate the biomechanical problems that initially led to the need for the surgery. Regenexx urges patients suffering from knee injuries or degenerative conditions to consider all of their options. 

At Regenexx we invented a new approach to orthopedic care we call Interventional Orthopedics. This approach involves the use of image guidance (flouroscopy and ultrasound) to precisely place high-dose stem cells or platelets from your body directly where they are needed in a specific joint structure. These cells then work in the site of your injury to grow into new, healthy tissue, a process that will only occur if the cells have been placed exactly where they need to go in order to achieve positive outcomes for the patient. This precise approach to orthopedic care can’t be replicated by a surgeon or nurse in a chiropractor’s office. Interventional Orthopedics requires thousands of hours of training following a standardized protocol process to become a licensed Regenexx physician.

The innovative Regenexx procedures restore knee function and mobility and decrease pain without the need for surgery by regenerating damaged tissue. During this outpatient procedure, our expert physicians use precise image guidance to inject custom concentrations of your body's natural healing agents into the exact areas of damage to tighten and stabilize your knee joint for better function and mobility. 

This page contains an extensive library of educational resources on knee conditions and our patented knee procedures created by Regenexx and our founder, Chris Centeno, M.D.. We encourage you to research your options.
