Musculoskeletal (MSK) ultrasound uses high-frequency sound waves to create real-time images of muscles, tendons, ligaments, nerves, and joints. This technology has brought safe, efficient imaging directly into the exam room and allows Boston Orthopaedic & Spine physicians to locate the precise point of a patient’s pain or discomfort.
The Diagnostic Power of MSK Ultrasound
Jennifer Luz, MD, double board-certified sports medicine and physical medicine and rehabilitation physician, utilizes MSK ultrasound often in her practice for non-operative treatments.
“When a patient comes in experiencing pain, I can utilize MSK ultrasound in the office at that appointment. Logistically it’s a lot easier for the patient. I’m doing the imaging, I’m looking at it in real time with the patient, and interpreting it for them.”

This interactive process significantly enhances patient understanding and engagement in their own care. It allows for a detailed look at inflammation and injury, making it a wonderful modality to use in the exam room for a variety of conditions – and even allows for movement during scanning to produce dynamic images.
It’s also particularly useful for assessing conditions that are often missed or poorly visualized by other modalities, such as sports hernias, which often don’t show up on an MRI or a CAT scan very well, or for providing highly detailed imaging of the nerves.
Ultrasound-Guided Injections
Beyond diagnostics, the second major strength of ultrasound is its role in guiding procedures, particularly injections. Orthopedics has experienced an evolution from “blind injection” to fluoroscopy (X-ray guidance, which only visualizes bone) and finally to ultrasound. The ability to see soft tissue live is a game-changer for safety and accuracy.
“We can make sure that we’re avoiding any nerves, blood vessels, anything that we would not want to pass a needle through.
This precision is crucial. When an injection is performed under live visualization, your physician can ensure the medication is placed directly into the injured area.
“Sometimes we see surprises like cysts, and if I had just done it by feel, I wouldn’t have known that that cyst or that problem was there. It also makes sure that we’re targeting the right tissue.”
MSK Ultrasound and Regenerative Medicine
The precision of ultrasound is perhaps most critical when delivering advanced treatments like orthobiologics, such as Platelet-Rich Plasma (PRP) therapy. These are treatments where the patient’s own healing cells are harvested and injected to promote tissue repair, often used as an alternative to repeated cortisone injections, which can be detrimental to soft tissue and cartilage health over time. The ultrasound ensures the valuable healing cells are delivered with pinpoint accuracy to maximize their therapeutic effect.
Return to Play with Real-Time Imaging
The utility of MSK ultrasound doesn’t end with diagnosis and treatment; it extends throughout the recovery period, which is particularly important for athletes and active individuals. Physicians in sports medicine also utilize it extensively to monitor healing and guide decisions on return to play.
Dr. Luz provides an example of a hamstring tear:
“Often hamstrings feel better before they truly are healed. I can follow the patient every couple weeks and repeat the ultrasound and compare the images at each point in time to make sure that I’m seeing healing in that hamstring.
We can look with the ultrasound and answer the question, is it truly healed or do we need to just give it a couple more weeks? It’s an incredibly useful tool for following an injury.”
For the athletic population, this detailed monitoring is an excellent safeguard for preventing reinjury and complements other treatments like physical therapy.

MSK Ultrasound is Safe and Accessible
For patients who may be hesitant about medical imaging, Dr. Luz emphasizes a major advantage of ultrasound: safety, and comfort.
“We can use ultrasound very safely on everybody. There’s no radiation. Ultrasound uses sound waves that bounce off tissue to create a picture.
And with MRI’s, a lot of people can’t tolerate MRI’s because they’re claustrophobic. With ultrasound, obviously there’s no claustrophobia. We’re simply applying a probe, a handheld device to the patient’s skin. It doesn’t hurt.”
Just as it is used during pregnancy to provide imaging of the womb, its safety means it can be used on all body parts, on metal implants, and even on babies, making it an accessible and well-tolerated imaging modality for virtually anyone seeking orthopedic care.
By merging immediate diagnosis, precise procedure guidance, and dynamic healing assessment, MSK ultrasound is establishing itself as a standard of care that offers patients a safer, more efficient, and more effective path to recovery.
