State-of-the-Art Musculoskeletal & Spine Care

Leading the shift in orthopedics and sports medicine
ROSM (Regenerative Orthopedics & Sports Medicine) walks you down the path of healing by providing innovative treatments. Our team is incredible at healing active injured humans. We use cutting-edge technology, new techniques, and a holistic approach to get YOU active again – without surgery.

ROSM is leading a paradigm shift in orthopedics and sports medicine. We help shape our industry by remaining rooted in peer-reviewed research and scientific evidence. Our physicians are supported by a framework of continuing education and collaboration with complementary fields like physical therapy and nutritional supplementation.

Diagnostic Ultrasound Evaluation
Your ultrasound evaluation will take between 30-60 minutes. There is no preparation required. There are no contraindications to an ultrasound evaluation and no limitations following the visit.
Musculoskeletal Screening
At the ROSM, we do not simply provide a screening consultation. Rather, we focus on providing a holistic approach to evaluation and treatment.

This includes a thorough physiatric evaluation with an emphasis on performance deficits. We strive to provide efficient care and therefore an ultrasound evaluation is often utilized to help determine the precise diagnosis, prognosis and treatment plan. The key to many of our success stories is determining an accurate functional diagnosis.


Platelet-Rich Plasma Technique
Concentrating healing factors in the patient’s own blood, PRP is thought to improve signaling and recruitment and other healing factors, nourishing injured tissue and encouraging self-repair.
About 60 mL of blood is drawn and processed on the same day. Total time spent in office is about one hour.
Bone Marrow Concentrate (BMC) Therapy
Also known as bone marrow aspirate concentrate (BMAC) therapy utilizes the patient’s own marrow (harvested under local anesthetic) to obtain ‘pluripotent’ stem cells. Typically used for moderate to severe osteoarthritis and severe tendon injuries.
Bone marrow is typically harvested and processed from the patient’s hip bone under local anesthetic and sterile procedure. Total time spent in office is 60 – 90 minutes.
Adipose-derived Stem Cell Therapy
Utilizing the patient’s own metabolically active fat tissue, adult stem cells are harvested and processed via a proprietary method. Like BMAC, this treatment has great success with moderate to severe tendon injuries.
Fat tissue is harvested under local anesthetic, processed and injected within the same visit. Total time spent in office is 60 – 90 minutes.
Prolotherapy gently kick-starts a healing cascade using a series of dextrose (sugar) injections. Within body tissue, dextrose acts as a mild irritant triggering an inflammatory response that will, in turn, signal repair tissue.
Prolotherapy is most beneficial for mild joint pain and osteoarthritis as well as helping with spine pain and instability. Total time spent in the office is about 30 minutes.


Subcutaneous Perineural Injection Treatment (Lyftogt technique)

This technique is used to desensitize chronically inflamed and painful nerves. Providers are trained in the specific locations of the painful nerves, and provide subcutaneous injections (just under the skin) with a tiny needle to treat those most sensitive nerves. It typically takes 4-6 injections to desensitize the nerve, but thereafter pain relief is expected to be long-term.

Platelet Rich Plasma (PRP) Injections
By concentrating platelets and healing cells of the immune system while removing unwanted inflammatory and red blood cells, PRP is rich in growth factors to encourage healing of soft tissue injuries. It also has been shown to help with chronic tendon problems and especially in mild-moderate osteoarthritis. Deep Perineural (Hydrodissection) Injection Treatment: This advanced ultrasound guided injection is used to free up entrapped nerves over long distances to decrease nerve inflammation and pain, and improve nerve function and health.
Bone Marrow Aspirate (BMA) and Bone Marrow Aspirate Concentrate (BMAC) Injections
Under local anesthesia, the bone marrow is harvested to obtain a rich blend of cells including platelets, hematopeitic (blood-cell forming) stem cells and other stem cells. Using especially designed tools and/or concentrating devices, we optimize the cellular content to encourage a robust healing response in orthopedic injuries. BMA/BMAC injections are used in cases with more serious damage to tendons, ligaments and joints (osteoarthritis).
Autologous Microfragmented Adipose Injections
Using minimally invasive techniques the patient’s own fat tissue is harvest and processed to provide a graft rich in both reparative cells (including stem cells) and also extracellular matrix which provides a nice scaffold upon which the healing proceeds. Fat or adipose has been used in medicine for years to fill voids and provide lubrication. In Orthopedics, this applies well to tendon and ligament tears as well as stiff and painful joints.
Musculoskeletal Prolotherapy
Prolotherapy gently kick-starts a healing cascade using a series of dextrose (sugar) injections. Within body tissue, dextrose acts as a mild irritant triggering an inflammatory response that will, in turn, signal repair tissue.
Prolotherapy is most beneficial for mild joint pain and osteoarthritis as well as helping with spine pain and instability. Total time spent in the office is about 30 minutes.


Perineural Injection Treatment (Lyftogt Technique)
Like MSK prolotherapy, perineural injection treatment is a series of dextrose or sugar injection placed just below the skin with a fine needle. Unlike musculoskeletal prolo, perineural injection treatment injections are targeted on areas of pain. This treatment has great success for various neuralgias, tennis elbow, knee pain, and other ongoing joint, tendon, ligament, and muscle pain.

"ROSM gave me my life back!"

ROSM gave me my life back! PRP treatments helped to heal a shredded tendon in my hip. After 4 treatments and lots of PT, I am a new person. The staff is lovely and happy to see you. I wasn’t able to get off the floor, let alone do my power walks with friends and sleeping was out of the question. I am still working on healing, but almost there.

"I am finally pain free"

The ROSM staff has great listening skills, is patient, and very attentive. I’ve worked with the doctors on and off over the last few years to diagnose several areas of pain in my lower back hip region that others haven’t been able to pinpoint. Today I am finally pain free after prolotherapy and am very thankful. Will continue to spread the word about the great work you and your team do.

"One of the best experiences I have ever had at a doctor's office"

My experience at ROSM was one of the best experiences I have ever had at a doctor’s office. They are truly miracle workers and treated me with kindness care and the level of service I wish all medical professionals demonstrated.
