For many people living with orthopedic pain, the treatment journey can feel frustratingly familiar.
You rest. You try physical therapy. You take anti-inflammatory medication. Maybe you’ve had injections. Yet the pain lingers, making everyday activities more difficult than they should be.
The good news is that today’s orthopedic medicine offers more options than ever before.
At Rothenberg Orthopedics, Regenerative & Sports Medicine (Roth ORSM), we specialize in modern, minimally invasive therapies such as MLS Class IV laser therapy, radial shockwave therapy, and precision shockwave therapy, which support your body’s natural healing response while reducing pain and improving function.
Although these treatments are often grouped together, they work in very different ways. Understanding the difference can help you have a more informed conversation with your provider and explore alternative, non-surgical treatment options.
Why some injuries heal slowly, or not at all
The human body has an incredible ability to repair itself. But healing isn’t always straightforward.
Acute injuries often improve within weeks because the body’s natural inflammatory response delivers nutrients, immune cells, and growth factors to damaged tissue. Chronic injuries, however, are different.
Over time, repeated stress, reduced circulation, tendon degeneration, arthritis, or simply aging can slow the body’s repair mechanisms. Tissues may become trapped in an ongoing cycle of irritation and incomplete recovery.
This is particularly common in tendons, ligaments, and other soft tissues that naturally receive a limited blood supply.
As a result, many patients reach a plateau. They’ve rested. They’ve stretched. They’ve completed physical therapy. Yet their symptoms are still there.
This doesn’t mean the injury is permanent. Instead, it may mean the tissue needs additional biological stimulation to restart or support the healing process. That’s where newer non-surgical therapies may play a role.
The surprising origins of modern therapies
They sound like cutting-edge innovations, yet laser and shockwave therapies have been around since the last century and are backed by decades of scientific development. Interestingly, both technologies originated in fields far removed from sports medicine.
Laser therapy: using light for healing
Did you know that LASER stands for Light Amplification (by) Stimulated Emission (of) Radiation?
In 1960, physicist Theodore Maiman developed the world’s first working laser using a synthetic ruby crystal. Lasers soon were used in surgery and later for therapy. Researchers were exploring whether carefully controlled light energy could influence tissues in our bodies. Over the following decades, advances in laser technology led to therapeutic systems capable of penetrating deeper tissues and supporting healing without damaging surrounding structures.
Lasers activate three biological effects—photochemical, photothermic, and photomechanical, which allows laser treatments to work on several levels—analgesic, anti-inflammatory, repairing, regenerative, and regulating.
Today’s MLS (Multiwave Locked System) Class IV laser therapy represents one of the latest developments in laser therapy evolution, combining multiple synchronized wavelengths designed to help reduce inflammation while supporting tissue repair.
Radial shockwave therapy: from kidney stones to orthopedics
The effects of shockwaves on the human body were discovered during the Second World War when explosions of depth charges near humans led to organ damage despite no signs of external physical trauma.
This led to decades of research. In the early 1980s, physicians began using focused acoustic waves to break apart kidney stones without surgery.
During follow-up research, clinicians noticed something unexpected. Bone and soft tissues exposed to these acoustic waves often demonstrated signs of enhanced healing.
That observation led to multiple research studies on orthopedic applications. Today, modified shockwave technologies are widely used to treat chronic tendon disorders, plantar fasciitis, and musculoskeletal conditions that have been slow to respond to conventional treatments.
Precision shockwave: bringing greater accuracy to chronic pain treatment
As shockwave technology evolved, clinicians sought ways to treat deeper tissues with greater precision.
Unlike traditional radial shockwave therapy, which disperses pressure waves over a broader area, focused or precision shockwave therapy concentrates acoustic energy at a specific depth within the body. When combined with diagnostic ultrasound, providers can target the exact tendon, ligament, or painful structure requiring treatment.
This evolution reflects a broader trend in orthopedic medicine toward more personalized, image-guided care, allowing treatments to be tailored to each patient’s anatomy and diagnosis.
Laser vs. radial shockwave vs. precision shockwave therapy: what's the difference?
Although these therapies are often mentioned together, each serves a different purpose. The “best” treatment depends on the underlying diagnosis rather than simply where the pain is located. These treatments are complementary. Each addresses different biological processes and may be appropriate at different stages of recovery.
MLS Class IV laser therapy: calming inflammation and supporting recovery
MLS Class IV laser therapy uses carefully controlled wavelengths of light to deliver energy into injured tissues (photobiomodulation). Instead of generating heat to destroy tissue, like surgical lasers do, therapeutic lasers are designed to stimulate cellular activity associated with healing.
Research suggests that photobiomodulation may help improve circulation, reduce inflammatory activity, and stimulate cells involved in tissue repair. While scientists continue studying the precise biological mechanisms, many patients experience gradual improvements in pain and mobility over a series of treatments.
One reason laser therapy appeals to many patients is its comfort. Treatments are noninvasive, require no needles or incisions, and typically last only a few minutes. Most patients describe a gentle warming sensation during the session, and there is generally no downtime afterward.
According to Dr. Rothenberg, laser therapy is particularly well suited for patients experiencing widespread inflammation or conditions affecting muscles, joints, and nerves rather than a single isolated tendon injury.
Conditions commonly treated with MLS laser therapy include:
- Arthritis and joint stiffness
- Low back pain
- Neck pain
- Muscle strains
- Neuropathy symptoms and nerve irritation
- Chronic inflammatory conditions
- Postoperative recovery support
Laser therapy may also be an excellent option for patients who prefer a gentle, medication-free approach or who are not ideal candidates for injections.
It’s important to remember, however, that laser therapy isn’t intended to replace rehabilitation or exercise. Instead, it is often one component of a comprehensive treatment plan designed to reduce pain enough for patients to move more comfortably and participate more fully in their recovery.
Radial shockwave therapy: a wake-up call for stubborn injuries
If laser therapy works by using light energy, radial pressure wave therapy, or radial shockwave therapy, uses acoustic pressure waves which it delivers into injured tissues.
Dr. Rothenberg describes radial shockwave therapy as providing a “wake-up signal” for tissues that have become chronically irritated or stagnant. This description captures an important concept.
Many chronic tendon injuries don’t necessarily suffer from ongoing inflammation alone. Instead, they may have entered a prolonged state of degeneration where normal healing has stalled. By delivering controlled mechanical stimulation, radial shockwave therapy is thought to promote increased blood flow and encourage tissue remodeling activity.
Because the pressure waves spread over a relatively broad treatment area, radial shockwave therapy is particularly effective for many common overuse injuries seen in both athletes and non-athletes.
It is frequently recommended for:
- Plantar fasciitis
- Tennis elbow
- Golfer's elbow
- Achilles tendinopathy
- Patellar tendon pain
- Chronic shoulder pain
- Chronic back pain
- Chronic neck pain
- Repetitive strain injuries
Many patients who benefit from radial shockwave therapy share a similar story. They’ve rested. They’ve completed months of stretching or physical therapy. They may have experienced temporary improvement, only to see symptoms return. These are often the patients who tell Dr. Rothenberg they feel like they’ve “tried everything.”
Treatment sessions are relatively short and performed in the office. Unlike laser therapy, some discomfort during treatment is normal, particularly when treating chronically irritated tendons. Mild soreness afterward is also common, although most patients resume their normal activities shortly afterward.
Perhaps most importantly, improvement isn’t always immediate. Because shockwave therapy works by stimulating biological repair rather than masking symptoms, many patients notice gradual improvement over several weeks as healing continues.
Precision shockwave therapy: targeted treatment for deeper or more complex pain
While radial shockwave therapy treats a broader area, precision shockwave therapy takes a more focused approach.
Using concentrated acoustic energy, it delivers treatment at a specific depth within the body, allowing providers to target an individual tendon, ligament, or painful structure with greater accuracy. At Roth ORSM, this precision can be further enhanced with diagnostic ultrasound, helping direct treatment exactly at where pathology exists.
That precision makes focused shockwave therapy especially valuable for patients with stubborn conditions that haven’t responded to other conservative treatments or when imaging identifies a clearly defined area of tissue damage.
Common conditions treated with precision shockwave include:
- Chronic tendinopathy
- Calcific tendinitis
- Proximal hamstring injuries
- Gluteal tendinopathy
- Insertional tendon disorders
- Deep back or neck pain
- Other chronic soft tissue injuries with a clearly identifiable source
Athletes often benefit from this targeted approach because treatment can be directed toward the exact tissue responsible for ongoing symptoms. And patients whose recovery has plateaued despite physical therapy, injections, or traditional shockwave therapy may be good candidates.
Treatment intensity varies depending on the condition being treated and is always adjusted to the patient’s comfort level. As with radial shockwave therapy, improvement may continue for weeks after treatment ends as tissue remodeling progresses.
Can these treatments help you avoid surgery?
This is one of the questions patients ask most often, and the answer is nuanced.
As Dr. Rothenberg puts it, “There are certainly situations where surgery remains necessary, and I believe in being honest with patients about that. However, many musculoskeletal conditions exist in a gray area where patients may have pain and dysfunction but are not at the point where surgery is inevitable.”
For conditions such as chronic tendon disorders, plantar fasciitis, calcific tendinopathy, early to moderate arthritis, and various overuse injuries, non-surgical therapies may improve symptoms enough to help patients delay surgery, or avoid it altogether.
Importantly, the goal isn’t simply to postpone surgery at any cost.
Instead, the goal is to provide evidence-based, minimally invasive options first whenever appropriate. If pain improves, function returns, and quality of life increases without an operation, many patients appreciate having had the opportunity to explore conservative care before considering surgery.
Why Rothenberg Orthopedics Regenerative & Sports Medicine often combines therapies instead of relying on just one
One of the biggest misconceptions about orthopedic treatment is that there is a single solution for every painful condition. In reality, healing is rarely that simple.
Pain may involve inflammation, tendon degeneration, muscle weakness, altered movement patterns, joint stiffness, nerve irritation, or several of these factors at once. That’s why Dr. Rothenberg frequently combines multiple therapies instead of relying on one treatment alone.
Depending on your diagnosis and goals, your personalized treatment plan may include:
- MLS Class IV laser therapy
- Radial or precision shockwave therapy
- Physical therapy and rehabilitation
- Orthobiologic treatments
- Guided exercise programs
- Activity modification and lifestyle recommendations
At Roth ORSM, we use each therapy as one tool within a comprehensive treatment strategy designed to help you restore movement, reduce pain, and improve long-term function.
Which treatment is right for you?
There isn’t a single answer, and that’s a good thing.
The most appropriate treatment depends on your diagnosis, the tissues involved, how long you’ve had symptoms, your activity level, and your goals.
For one patient, MLS laser therapy may help calm inflammation enough to make rehabilitation more effective. For another, radial shockwave therapy may provide the biological stimulus needed for a stubborn tendon injury. Someone else may benefit most from precision shockwave therapy targeted to a specific structure identified on ultrasound.
The key is choosing the right treatment for the right condition at the right time.
At Rothenberg Orthopedics, Regenerative & Sports Medicine, every treatment plan begins with a careful evaluation. By combining clinical expertise with evidence-based, minimally invasive therapies, Dr. Rothenberg and our team help patients explore effective alternatives before considering more invasive procedures.
If pain has been limiting your movement or keeping you from the activities you enjoy, schedule an evaluation as the first step toward understanding which treatment options may be right for you.
