Image-Guided Knee Pain Treatment Options in Van Nuys

Knee pain is not a single diagnosis. Osteoarthritis, injury, tendon or bursal problems, inflammatory disease, referred pain, and other conditions can feel similar but require different care. For patients in Van Nuys, a useful evaluation starts by identifying the likely pain source before discussing an injection, embolization, or surgery.

Image guidance can help a physician place a needle or catheter accurately. It does not guarantee that a procedure is appropriate or that pain will improve. Expected benefit, recovery, and risk depend on the diagnosis, the specific treatment, and the individual patient.

What image-guided knee pain treatment means

Interventional radiology uses ultrasound, fluoroscopy, or angiography to guide selected procedures. The imaging method and treatment goal vary. Some patients need conservative care or orthopedic evaluation rather than an image-guided procedure.

A review may include the symptom pattern, physical examination, prior treatment, X-rays or other imaging, medications, allergies, kidney function, vascular history, and the patient’s activity and treatment goals.

Knee treatment options should be compared, not assumed

Conservative and orthopedic care

Exercise-based physical therapy, activity modification, weight management when relevant, topical or oral medication, bracing, and assistive devices may be appropriate for knee osteoarthritis. Orthopedic evaluation is important when structural disease, instability, trauma, or possible joint replacement needs to be assessed.

Image-guided injections

Image-guided injections can improve placement accuracy, but whether an injection is appropriate—and how long any relief lasts—depends on the diagnosis, medication, and individual response. Risks and alternatives should be discussed before treatment.

Genicular artery embolization

GAE is an evolving, minimally invasive catheter procedure studied for selected patients with knee osteoarthritis pain. Results vary, and sham-controlled trials have reported mixed findings. Review genicular artery embolization candidacy, risks and evidence before treating it as an alternative to established knee care.

GAE is intended to reduce selected abnormal blood flow associated with synovial inflammation. It does not regrow cartilage, correct alignment, stabilize an unstable knee, cure osteoarthritis, or guarantee that knee replacement will be avoided.

Who may be considered for a GAE evaluation?

GAE may be discussed for selected adults with imaging-confirmed knee osteoarthritis and persistent symptoms despite an appropriate conservative plan. Patient selection also considers whether osteoarthritis is the main pain generator, vascular anatomy, skin circulation, kidney function, contrast allergy, medications, and plans for orthopedic care.

Symptoms suggesting infection, fracture, acute vascular problems, inflammatory arthritis, or pain coming from the hip or spine require appropriate evaluation. A consultation does not guarantee that GAE or another procedure will be recommended.

Recovery and risks depend on the procedure

After GAE, many patients leave following a period of observation, but driving, wound care, medication, and activity instructions are individualized. Access-site soreness, bruising, fatigue, or a temporary pain flare can occur. Response is generally assessed over weeks to months, and some patients do not improve.

Potential risks include bleeding or artery injury at the access site, skin discoloration or ulceration, infection, contrast reaction, kidney injury, numbness or nerve injury, radiation exposure, and rare non-target embolization. Worsening pain, fever, drainage, color change, persistent numbness, or a cold foot should prompt a call to the treating team; emergency symptoms require emergency care.

Questions to ask during a knee-pain consultation

• What is the most likely cause of my knee pain?
• Which imaging findings support that diagnosis?
• What conservative and orthopedic options remain reasonable?
• If a procedure is considered, what benefit is realistic and what evidence supports it?
• What are the procedure-specific risks and recovery restrictions?
• Could this treatment affect the timing of later orthopedic care?

If knee pain is limiting daily life, an evaluation can help confirm the cause and compare conservative, image-guided, and surgical options. Request a consultation with Dr. Nathanael Sabbah; a consultation does not guarantee that a procedure will be recommended.
