Ultrasound-Guided Care and In-Office Needle Arthroscopy

Nearly every evaluation at Texas Orthobiologics comes down to one question: what is actually causing the pain? History and physical exam narrow the list, and imaging settles it. This page collects what Don Buford, MD has written about the two imaging tools he uses in the office every day, musculoskeletal ultrasound and in-office needle arthroscopy, both for diagnosis and for guiding orthobiologic injections. It is written for patients deciding where to be evaluated and for physicians deciding where to refer.

What office ultrasound shows that a report cannot

Musculoskeletal ultrasound shows joints, tendons, ligaments and other soft tissue in real time. The patient moves, the structure moves, and the clinician watches it happen while the patient is sitting there. Dr. Buford has made the same argument on this blog since 2018: ultrasound is a strong diagnostic tool that can often take the place of an MRI scan and produce a diagnosis during the same visit rather than weeks later.

The clearest example here is the meniscus. Many meniscus tears can be identified with office ultrasound at the first visit, which skips both the scheduling delay and the pre-authorization step that come with an MRI. The limit is stated just as plainly in that post: not every tear is visible on ultrasound. When the scan does not answer the question, the right response is a different test, not a guess. Imaging is one input alongside the history, the exam and, when indicated, blood work or neurologic testing.

Needle arthroscopy, and the position that anchors this practice

Sometimes there is only one way to know what is happening inside a joint, and that is to look inside it. The mi-eye 2 is a single-stick disposable needle arthroscope that does exactly that, under local anesthesia, in the office, in about five to ten minutes. Dr. Buford has used it for diagnostic knee and shoulder arthroscopy at the visit itself in place of a 45 minute MRI, and the posts here report the procedure as covered by insurance. It runs on the same tablet platform as the office ultrasound, so both the scan and the scope are available in one room.

This is where Dr. Buford states his professional position most directly, and it is the reason this hub exists: only an orthopedic surgeon is trained to combine in-office needle arthroscopy with regenerative medicine. Arthroscopy is a surgical skill, learned in surgical training and kept current by operating. A regenerative medicine clinic staffed by clinicians who are not orthopedic surgeons cannot legitimately offer diagnostic arthroscopy, whatever else it may offer well. That is a statement about scope of training rather than a criticism of any individual practice, and it has a practical consequence for the patient: the same visit can produce a direct look inside the joint, a biologic injection placed under guidance, and, if the joint turns out to need it, a surgical opinion from the person who just looked at it.

Why guidance matters once treatment starts

A PRP or bone marrow concentrate injection can only act where it lands. Ultrasound lets the needle be watched into the target and the injectate be watched as it spreads, which is why every orthobiologic procedure described on this blog is done under guidance. The case posts collected below show what that looks like in practice: gluteus medius and minimus tendinopathy found on ultrasound after ten years of steroid shots and treated with an LP-PRP injection prepared from 60cc of blood, chronic Achilles tendinitis with partial tearing that had not improved after five months of other treatment, calcific tendinitis at the knee where the ultrasound-guided procedure is used to remove the calcium itself, and a meniscus tear with knee arthritis treated with a guided bone marrow concentrate injection.

Two honest qualifiers belong with those cases, and Dr. Buford writes them into the posts himself. Not everyone is a candidate, and results vary between patients with what looks like the same problem on the screen. Guidance makes placement accurate. It does not make every injection work, and no one should be told otherwise.

Guidance also applies before the injection. The bone marrow draw is done in the office under ultrasound as well, and one post here compares two approaches to that harvest: a technique that aspirates and injects 8 to 10cc of marrow directly against a Jamshidi aspiration that is then centrifuged and concentrated. That kind of side-by-side testing is covered further in the research hub.

A skill that has to be taught and kept current

Scanning well is a volume skill. Dr. Buford directs the Las Vegas Regenerative Medicine and MSK Ultrasound Course, which reached its 25th session in nine years back in 2018 with well over 1000 clinicians trained and is now in its 18th year. He has also led the MSK ultrasound training course at the Arthroscopy Association of North America annual meeting and has taught at the San Diego Shoulder Course since 1999. For a patient the useful version is simple: the person holding the probe should be someone who holds it daily and teaches other physicians to do the same.
