Regenerative Orthopaedics uses cutting-edge technology to stimulate and accelerate the healing process. Depending on age, health and the severity of  condition treatments may include; stem cell therapy, platelet-rich plasma therapy, and other non-operative treatments.

These therapies are performed as a same day, office-based procedure and require minimal recovery time for patients. Although success may ultimately depend on the site and severity of the injury, improved pain and function can last for years.

PRP and Stem Cell Injections & Regenerative Therapy

While stem cells have the ability to differentiate and form brand new cells, platelets are a small fragment of blood cells, which help in clotting and enhance the healing process. The growth factors present in the platelets work to simulate those cells essential for a quicker recovery. An added benefit of PRP is that the patient faces less risk of infection or allergic reactions due to the procedure, as the injected platelets are of their own blood. This combined with the fact that the procedure itself is quick and does not require general anesthesia or a prolonged recovery makes it a viable option for situations where standard treatments have proven to be ineffective.

Platelets are cells that clot blood and contain over 300 active growth factors. They also contain hormones that help to facilitate growth and healing. The process of extraction followed by centrifugation of the blood allows platelet-rich plasma to be separated from the original sample which is then injected into the site of the injury. For those patients whose tissues are aging and therefore have a slower or reduced ability to repair and regenerate, the growth factors in PRP can help to improve the body’s healing ability.

Advantages include:

  • Long-term pain relief
  • Quicker recovery time
  • Improved function
  • Improved healing potential

Common Areas of Treatment:

  • Tendon or Ligament injury (tear, sprain)
  • Tendonitis
  • Arthritis
  • Muscle Strains
  • Articular Cartilage Injury

Our onsite diagnostic imaging department aids our physicians in quickly and accurately diagnosing your injury or condition. Because radiologic exams are common during an orthopaedic visit, we have developed programs that are efficient, effective, and convenient.

SRO’s Sports Medicine Center offers comprehensive diagnostic x-ray capabilities. We have also incorporated a state-of-the-art open Magnetic Resonance Extremity (MRI) Scanner, helping to eliminate the claustrophobic feeling some patients experience with traditional MRI. Each of our technologists is fully certified in his or her area of expertise. All of our MRI interpretations are performed by board certified radiologists specializing in musculoskeletal diagnoses.

Santa Rosa Orthopaedics offers a revolutionary surgical option for some joint replacement patients using the robotic assisted device called RIO Robotic Arm Interactive Orthopedic System. This highly advanced procedure is essentially a minimally invasive technique that reduces damage to the bone and surrounding tissue for faster recovery. The MAKO®  system is currently available primarily for partial knee replacement and is offered by both Dr. Michael McDermott and SRO’s Dr. Nathan Ehmer at Sutter Santa Rosa Regional Hospital.

The MAKO robotic arm interactive system’s unique design makes it possible for a surgeon to “pre-plan” the procedure on the computer. This way, the robotic arm ensures precision in the resurfacing of the damaged portion of the joint followed by more accurate placement of artificial implants and correct tensioning of ligaments. The robotic system offers a number of benefits particularly for knee replacement surgery. One of the primary advantages is that we require a much smaller “mini-incision” and most patients experience a much a faster recovery as a result.
