Below are a few of the ailments we work with:

Knee Joint

Patellar (Knee) Tendonitis & Tendinosis Patellar tendonitis and patellar tendinosis differ by the degree of inflammation present. Tendonitis presents with more inflammation of the tendon around the patellar joint, whereas tendinosis is primarily the tearing and failure to heal of the ligament. Both conditions are associated with ongoing pain in the knee area. Sometimes the disorders are referred to as “jumper’s knee” or “Sinding-Larson- Johansson Disease.” The conditions are often caused by overuse injuries, which fail to properly heal. Tearing, degeneration, and subsequent inflammation is how the disease progresses in most patients. Platelet Rich Plasma (PRP) Therapy can provide significant relief of this painful condition.


Quadriceps Strain or Tear Straining the front muscles of the thigh (quadriceps) is a result of a tear in the fibers within the quadriceps muscle or tendon. There are varying degrees of quadriceps strain, identified by three levels of severity. Quadriceps strains or tears which fail to heal can be address successfully with Platelet Rich Plasma (PRP) therapy. This form of therapy isolates and activates Growth Factors from Platelets of a patient’s blood stream. They can then serve as a natural Growth Factor treatment of one’s own body.


Degenerative Arthritis of the Knee Degenerative arthritis of the knee is a painful, sometimes debilitating inflammation where the thigh and leg bones meet. This disease, also referred to as Osteoarthritis of the Knee, is a cumulative effect of ongoing deterioration of the cartilage between these bones. As the cartilage thins and wears away, more direct contact and pressure between the bones of the knee joint develops. This can result in significant pain, inflammation and loss of mobility. This disease can also impact other joints such as the hips, spine, shoulders, hands and wrists. In the most severe cases joints can become deformed and lose their primary function which is mobility.






Meniscus Tear A meniscus tear is a common knee injury related to sports activities or even just an unusual force on the meniscus from twisting of the knee. The meniscus of the knee joint is a rubbery type of cartilage which acts as a shock absorber force distributor between the thigh and leg bones. Very active younger adults as well as older adults with existing meniscus degeneration are more prone to meniscus tearing and injury. In many cases, doctors will recommend arthroscopic surgery to repair the meniscus tear. This requires the doctor to insert a miniature camera through a small incision to see the inside of the knee. Then, a surgeon will either remove the damaged meniscus tissue or stitch the torn meniscus pieces together. For some patients, a surgeon may decide that a knee arthroscopy is not the best option, or patients may have failed surgery. In these instances, Stem Cell Therapy or Platelet Rich Plasma Therapy may be a viable alternative.


Hip Joint

Hip Joint Arthritis Arthritis pain of the hip is often caused by a lack of cartilage around the hip joints. Traditional treatment for hip joint arthritis often consists of pain medication or surgery, but at the Institute of Regenerative Medicine, we use Stem cell therapy to rebuild and regenerate the cartilage and fluid within their hip joints, therefore improving and even potentially curing the patient’s hip arthritis. We have been at the forefront of stem cell therapy research and have successfully treated many arthritis patients with our unique approach. Our treatment allows patients to resume their active lifestyle without the need of surgery or pain medication.

Avascular Necrosis and Osteonecrosis of the Hip Avascular necrosis and osteonecrosis of the hip joint are conditions where bone is suffering from a lack of blood supply. This leads to injury and ultimately destruction of the bone tissue. Patients of advanced age as well as those suffering from other disease states such as autoimmune diseases are prone to the development of Avascular Necrosis and Osteonecrosis of the hip joint. Patients often experience hip pain, stiffness and loss of mobility. Advanced cases of this disease process require surgery, however earlier cases can potentially be treated with Stem Cell Therapy (SCT). This involves the harvesting of Stem Cells from bone marrow and Fat Tissue which can then be isolated and activated to treat the diseased areas of bone.

Hip Bursitis Ischial tuberosity and greater trochanteric bursitis are conditions where the fluid filled sacs next to the hip joint become inflamed and painful. This is a common occurrence in long distance runners or those who start running after a not having exercised for longer periods of time. It can also occur when sitting stationary for longer periods of time. Ultimately patients experience ongoing hip pain and difficulty walking. Patients who do not respond to conservative treatments such as rest, anti-inflammatory medications and Physical Therapy can often be helped by Platelet Rich Plasma (PRP) therapy.

Shoulder Joint

Biceps Tendinitis and Tendinosis Biceps Tendonitis and Tendinosis often results from overuse or strain of our Biceps muscle and tendons. It is a common issue related to activities such as weight lifting in younger adults and more simple lifting activities in older adults. While the body may be able to repair some of the smaller tears and injuries on its own, some patients will require further rehabilitative treatment to encourage the body to heal completely. For ongoing Biceps Tendinosis or Tendonitis, Platelet Rich Plasma (PRP) injections, or for more serious and chronic versions Stem Cell-based treatments may be required. Stem Cells can be simply harvested from the bone marrow, blood, and fat tissue to be used as a Stem Cell treatment for these conditions.

Rotator Cuff Injuries Rotator Cuff Injuries of the shoulder joint are a common overuse and degenerative condition. The Rotator Cuff consists of a group of muscles which provide strength and stability to the shoulder joint. Younger patients can injure the Rotator Cuff through overuse, while older patients often sustain injuries due to chronic underuse and weakening of this important muscle group. Traditional treatments for a torn rotator cuff involves medication for inflammation, cortisone injections, and months of physical therapy. In many cases, shoulder surgery would be needed if these methods failed to improve the patient’s condition. If surgery is not deemed to be an option or fails to provide relief, Platelet Rich Plasma (PRP) and Stem Cell treatments can be used as a form of treatment. Growth factors and Stem Cells from our own body can be used to provide healing of the inflamed and degenerated muscles and tendons of the Rotator Cuff.

Shoulder Sprain The most common forms of shoulder sprains can heal simply through rest or through physical therapy. However, sprains of the glenohumeral ligament of the shoulder can become a chronic problem causing pain and disability. Stem Cells and Platelet Rich Plasma treatments can help heal chronic shoulder sprains, if surgery is not an option.

Acromio-Clavicular Joint Dysfunction The Acromio-Clavicular joint, or “AC Joint” is the joint where the shoulder blade and collarbone meet. It is commonly acutely injured when falling on an outstretched arm, but can also chronically degenerate from repetitive strain on the joint. Common symptoms, include shoulder pain and stiffness as well as lack of mobility.

Rest, as well as temporarily immobilizing the joint by wearing a sling can be effective in treating milder cases of AC joint injuries or dysfunction. For more serious cases, however, surgery may be required to properly address the problem. In cases where surgery is not advised or has failed to provide relief, Platelet Rich Plasma (PRP) or Stem Cell Treatments can be an option. These treatments are designed to provider permanent reduction in pain and inflammation by providing a biological form of treatment.

Shoulder Arthritis Similar to other joints in the body, the shoulder joint is prone to overuse, inflammation and ultimately the onset of arthritis. This condition is especially common in patients who have engaged in ongoing heavy lifting activities related to sports or work. Ultimately patients experience joint pain and loss of motion over time. Patients who fail conservative medical care may be considered for surgical joint replacement. As an alternative, some patients may benefit from Stem Cell Therapy (SCT).

Back and Spine







Facet Joint Arthritis

Color MRI Lumbar Spine Facet Arthritis

Arthritis of the Spine Joints (Facet Joints) is a common condition of the aging spine. It is often the consequence of small injures and common wear and tear. Facet joints support the back of the spine, as opposed to spinal discs which are located in the front of the spine and act as “shock absorbers”. Just like other weight bearing joints of our hips and knees, facet joints are prone to joint and cartilage degeneration causing pain, stiffness and loss of mobility. Facet joint arthritis is often difficult to treat, but can respond to anti-inflammatory medications and injections. In severe cases, surgery can be recommended. Platelet Rich Plasma (PRP) and Stem Cell Therapy (SCT) can be an effective alternative, potentially leading to long term relief of symptoms.


Muscle Spasticity Syndromes Chronic back pain often has a significant muscle component. The powerful muscles which provide our spine with strength and mobility, are also prone to injury and overuse, causing chronic back pain and muscle spasticity. Patients often experience sharp stabbing pain or chronic dull pain with minimal activities or even at rest. The most common treatments are anti-inflammatory or anti-spasm medications as well as Physical Therapy or back injections. Platelet Rich Plasma (PRP) injections which provide an advanced anti-inflammatory and Growth Factor treatment may provide long term relief of symptoms.

Elbow Joint

Ulnar Collateral Ligament Injury Ulnar Collateral Ligament (UCL) injuries area common form of sports injuries due to overuse at the elbow joint. It is especially common in ball sports such as baseball, however can also results from simple forms of elbow trauma. Typically, pain is felt at the elbow, arm and wrist areas. The most common initial forms of treatments for UCL injuries are resting the elbow joint and Physical Therapy. For more chronic injuries with significant impairment by pain and loss of mobility, surgery is often considered. However, for patients who are not surgical candidates or fail obtain relief of their symptoms with surgery, Platelet Rich Plasma (PRP) or Stem Cell Treatments can be a valid treatment option.

Tennis Elbow Tennis Elbow also referred to as Lateral Epicondylitis is an inflammation of the bone and muscle tendons on the outside of the elbow. While this condition classically develops from overuse of the elbow tendons through sports activities such as Tennis, it can also result from simple overuse and small injuries related to everyday activities. Tennis elbow typically causes ongoing elbow pain with minimal activity or even at rest. This is often exacerbated by lifting of items. Lateral Epicondylitis often responds to simple conservative medical measures, such as rest, anti-inflammatory medications and braces. However more severe or chronic cases by require surgery. Cases which do not qualify for surgery can often be treated successfully with Platelet Rich Plasma (PRP) or Stem Cell Treatments (SCT).

Foot and Ankle Joints

Achilles Tendonitis and Tendinosis The Achilles Tendon is a crucial tendon to provide strength and mobility at the ankle joint. Inflammation (tendonitis) or chronic non-healing injuries (Tendinosis, tendinopathy) can cause significant pain and loss of mobility even with everyday activities such as walking and stair climbing. While common causes of Achilles Tendon issues are injuries related to straining of the tendon, patients with advanced age or chronic illness can suffer this condition related to loss of normal tissue in and around the Achilles Tendon. Initial treatment approaches include conservative care such as ice, rest and Physical Therapy. More advanced cases which do not require surgery can be addressed with Platelet Rich Plasma (PRP) and Stem Cell Therapy (SCT).

Plantar Fasciitis Plantar fasciitis is a common painful and at times debilitating condition that primarily affects athletes, as well as people whose jobs require them to stand for long periods of time. Other risks involve improper shoe ware and lack of the normal arch of the foot. In these cases, the strand of tissue at the bottom of the foot (plantar fascia) becomes inflamed and injured. This causes pain along the sole or at the heel of the foot, which can impair the ability to walk. While simpler forms of this condition can respond to rest, anti-inflammatory medications and Physical Therapy, more advanced forms can be addressed with Platelet Rich Plasma (PRP) and Stem Cell Treatments (SCT).

Ankle Joint Arthritis Similar to other weight bearing joints in the human body, the ankle joint is prone to overuse, cartilage degeneration and ultimately arthritis. This process can be related to the accumulation of small injuries, genetics and simple wear and tear. Ultimately patients experience pain and stiffness at the ankle. In extreme cases, a surgical joint replacement can be considered. Stem Cell Therapy can be a viable alternative with the potential for long term pain relief and maintenance of joint function.
