At the Barr Center, our approach to knee joint pain relief begins and ends with our patients. The knee is the largest joint in the body and consists of three compartments that work together as a modified hinge joint, allowing bending and rotational movement. The knee enables walking, running, climbing, squatting, lifting, and carrying.
Injuries and degeneration from wear and tear can affect any of these compartments, leading to ligament and tendon strain, inflammation, swelling, cartilage tears, arthritis, and bursitis. Knee pain can significantly limit everyday activities such as walking, stair climbing, kneeling, turning, and exercise. Many patients seek care because knee pain prevents them from maintaining an active lifestyle due to injury, degeneration, or medical conditions.
Our treatments focus on restoring your ability to live a healthy, active life. This begins with identifying the source of your pain and addressing primary pain generators, followed by evaluating compensatory issues that develop in response to pain.
Knee pain commonly develops from everyday wear and tear, overuse, injury, or aging. Pain may originate from the knee joint itself or surrounding muscles, ligaments, and tendons. Pain related to joint compartments or associated structures typically worsens with activity. Night pain with tenderness below the knee on the inner leg is often associated with pes anserine bursitis.
Instability from trauma or hypermobility syndromes can also contribute to knee pain, making diagnosis and treatment complex.


In some cases, knee pain does not originate from the knee itself. Osteoarthritis of the hip or lumbar spine conditions, particularly at the L4 level, can refer pain to the knee.
During your first appointment, we will review your symptoms, medical history, and contributing factors. A physical exam and imaging studies such as X-rays or diagnostic musculoskeletal ultrasound may be used to reach an accurate diagnosis.

Dr. Lisa Barr discusses what to expect during an initial visit to the Barr Center. Patients are encouraged to fill out new patient paperwork beforehand to help identify potential causes of pain. Upon arrival, patients will be processed and taken to an exam room for a history and physical examination. The goal is to identify root causes and triggering events that may be contributing to the pain. A comprehensive treatment plan will be developed based on the findings.
The cold laser has been called “The Therapy” of the 21st century. In over 1,700 publications, there have been no recorded negative side-effects. This versatile tool is totally safe, non-toxic, and easy to use.
Over the past thirty years of using cold laser therapy, it has become one of the most versatile conjunctive tools we have ever used. It has potent synergistic effects with regenerative and nutritional therapies. It is both doctor and patient friendly. This promising tool is called the cold laser, the soft laser, the low-power laser, or the low-level laser. The term laser is an acronym for Light Amplification by Stimulated Emissions of Radiation.
All lasers emit coherent, focused light that travels in a narrow beam in one direction. High Power, “hot” lasers have shorter wavelengths, which have catabolic effects that can deliberately destroy tissue in cauterizing and surgical applications. Low Power, “soft”, “cool”, or “cold” lasers have longer wavelengths that have anabolic effects that promote rapid reduction of pain, accelerate healing time, and accelerate growth and repair.
Cold lasers or low-level laser therapy (LLLT) have stimulative effects rather than destructive ones. Clinical applications of the cold laser have included acute and chronic pain reduction from many etiologies, inflammation reduction, enhanced tissue healing, and cell regeneration. The results have shown very rapid pain reduction and accelerated recovery times, far exceeding conventional methods.
The Barr Center lasers made history by becoming the first to receive FDA market clearance for the treatment of chronic pain and increasing range of motion, proven through two double blind IRB studies.
Our Erchonia Lasers are the most advanced lasers on the market, with their sleek revolutionary design, patented line generated beam, and the ability to program independent frequencies in all of their family of lasers. It has been found to be extremely beneficial for enhancing and accelerating wound healing and reducing acute inflammation.
Unlike high power lasers that use heat and destroy tissue, low energy lasers affect the cellular energy of the underlying tissue. Hot lasers have a thermal effect and have an output of 1MW or above. Cold (or) Low Level Lasers do not have a thermal effect on tissue: lasers that stimulate biological function have an output below 10mw- milliwatts (ten- one thousandths of a watt).
With over 200 clinical studies – many of which are double-blind, placebo-controlled – and in excess of 2,000 published articles on LLLT (low-level laser therapy), this innovative technology has a well-documented research and application history. Having grown far beyond its distant Institutional Review Board (IRB) and experimental treatment status, LLLT is now being considered a therapy of choice for difficult pain management challenges such as fibromyalgia and myofascial pain.
Low Level Laser Therapy for pain is FDA-cleared to successfully treat many conditions such as acute and chronic pain reduction, repetitive use disorders like carpal tunnel syndrome, soft tissue strains and sprains, inflammation reduction, enhanced tissue wound healing, and cell regeneration.

Dr. Lisa Barr provides an instructional video on how to use handheld lasers, explaining the process of turning on the laser, logging in, and accessing settings. Dr. Barr demonstrates how to navigate the screen and select the desired mode as well as reviewing the preprogrammed settings for different conditions and the laser’s ability to boost healing after regenerative medicine treatments.
Scar tissue can create an abnormal electrical signal in the autonomic nervous system. This signal is then transmitted through the autonomic nervous system throughout your body.
This is why a scar in one part of your body can cause pain in another area that is not even in close proximity to the scar.
Interference fields have lower electrical potentials than surrounding tissue. Electrical currents will flow from areas of higher voltage to areas of lower. Because of the disruption in electrical activity due to the presence of scar tissue, mixed signals are sent through the body’s nervous system. As a result, the body will react in ways that can lead to chronic pain and/or illness.
Cells in interference fields have an abnormal electrical charge on the cell surface. This results in abnormal signals being sent from the nerves to the brain (abnormal afferent signals). These signals then trigger abnormal autonomic nervous system responses. Local anesthetics affects the cells by stabilizing the membrane and normalizing the electrical charge. Even if the effects last for a short time, it allows for improved cellular metabolism, creating a healthier cellular environment and helping to stabilize the system. The improved cellular metabolism allows toxins to leave the cells and nutrients to enter, thereby reducing pain.
The injections are done using a very fine needle directed just below the skin (subcutaneously) into scars, nerves, acupuncture points, glands and trigger points. Sometimes deep injections are performed into the ganglia (a cluster of nervous tissue) or into a plexus (a network of nerves). The injections are done to eliminate the interference and restore the body’s natural energy flow.
After injecting the scar, sometimes a small amount of local anesthetic is injected into a vein, which helps stabilize the nervous system. Also, at times we inject small “blebs” of local anesthetic in a segmental fashion over other areas of the body where interference patterns or areas of abnormal electrical activity are found.
Dr. Lisa Barr of the Barr Center for Innovative Pain and Regenerative Therapies explains that spinal injections are performed in the fluoroscopy suite to address various pain issues. Barr Center uses X-ray equipment to accurately identify and target painful structures, injecting a combination of local anesthetic and steroids. The suite is used for diagnostic injections to pinpoint the source of pain and prescribe appropriate treatment. Epidural injections and radiofrequency ablation procedures are also performed in the fluoroscopy suite to alleviate chronic pain caused by arthritis. The goal of Barr Center is to help patients become pain-free.
Rejuvenation means boosting the body’s natural ability to heal itself. Regenerative medicine holds the promise of definitive, affordable health care solutions that heal the body from within. At the Barr Center we believe that under the right set of conditions the body has the capacity to heal itself. Regenerative therapies are a set of tools that we can use to reduce inflammation and facilitate healing in injured and degenerated joints, tendons and ligaments.
Dr. Barr and her staff have been at the forefront of regenerative medicine. She was the first physician to implement PRP, bone marrow-derived stem cells and fat grafting into practice in Hampton Roads over 20 years ago. She has successfully treated many patients, including professional golfers, with a variety of regenerative therapies for spinal, joint and tendon issues. Dr. Barr monitors the latest advances in regenerative medicine by regularly attending international conferences on
Regenerative Medicine, and she enjoys bringing back to our area the newest proven technologies. To complement her experience in regenerative medicine, she has advanced training in musculoskeletal ultrasound and interventional spinal injections. This is a key component to our success since these are mostly non-surgical treatments and the key to maximizing treatment outcomes for any regenerative therapy is optimal needle placement. Regenerative Medicine is ever-expanding. New concepts of managing inflammation and promoting tissue healing are being developed. Once we determine the best treatment option for you, be it PRP (Platelet Rich Plasma), Prolotherapy, Prolozone Therapy, Bone marrow concentrate, fat grafting, amniotic stem cells or a combination of modalities, we can perform the procedure in our office on the same day. The injections are performed using a small needle, cold spray and local anesthesia. To ensure optimal needle placement and maximize treatment outcomes, all regenerative therapies are performed at the Barr Center under image guidance using either ultrasound or x-ray. The entire process can take as little as 60 minutes. Within several days of undergoing most regenerative therapies, you can return to normal activities within 4-7 days.
