Point-of-Care Knee Ultrasound & Ultrasound-Guided Knee Injections
Many knee problems are diagnosed with a careful examination and X-rays. When a focused real-time look adds useful information—or when image guidance can improve a procedure—point-of-care ultrasound gives your orthopedic physician another set of eyes right in the room.

What Can Knee Ultrasound Help Evaluate?
Knee ultrasound is most useful when the clinical question involves something that can be seen well with a focused, real-time study. It is not a substitute for every knee MRI, but it can add useful information during the office visit.
Why not have an extra set of eyes when it helps?
The goal is not to ultrasound every knee. It is to use the tool when it improves the evaluation or procedure.Useful for Fluid and Focused Questions. MRI Still Matters.
Ultrasound and MRI answer different questions. Ultrasound can be immediate and useful for selected superficial or fluid-related problems. MRI is more comprehensive for many internal knee injuries.
Focused, real-time and office based
Useful for selected effusions, fluid collections, superficial tendons, bursae, cystic structures and image-guided aspirations or injections. It can sometimes answer a focused question during the same visit.
Better for many internal knee structures
MRI may be preferred when we need to evaluate a suspected meniscus tear, ligament injury, cartilage damage, occult bone injury or other internal structures that ultrasound cannot fully assess.
If MRI is the appropriate next step, Atlanta Bone & Joint offers orthopedic MRI.
More Visualization for Selected Knee Injections & Aspirations
Many knee injections can be performed accurately using anatomic landmarks alone. Ultrasound is most useful when the anatomy is difficult to feel, fluid needs to be targeted, or the physician wants direct visualization of needle placement.
Does Every Knee Injection Need Ultrasound?
No. Many knee injections are straightforward and do not require image guidance.
Ultrasound becomes more useful when the target is difficult to localize, when fluid is being aspirated, when anatomy is less predictable, or when the physician wants real-time confirmation of needle position.
The same principle applies to diagnosis. If the history, examination and X-rays already explain the problem, ultrasound may not add much. If a focused real-time image can answer a question immediately, it can be useful. And if the concern is an internal knee injury that needs MRI, then MRI should be obtained.
An Injection Is One Tool—Not the Whole Treatment Plan
Knee injections can help selected patients, but the diagnosis and severity of arthritis matter. Treatment should be based on symptoms, examination, X-rays, activity goals and response to nonsurgical care.
Depending on the situation, treatment may include activity modification, exercise, physical therapy, anti-inflammatory medication, cortisone injection, gel injection or, when arthritis becomes severe enough, knee replacement.

One More Way to Evaluate and Treat a Painful Knee
Ultrasound is not needed for every knee problem. But when a focused real-time image can help identify fluid, guide an aspiration or improve injection placement, it gives your orthopedic physician another useful set of eyes.
