Intra-articular Injections
Image-guided intra-articular injections for the knee, hip, shoulder, SI joint, elbow, ankle, and wrist — performed under real-time fluoroscopy or ultrasound to confirm accurate joint-space delivery.
Every Joint, Every Injectate — Guided with Precision
Intra-articular injections deliver therapeutic agents directly into the joint space to reduce inflammation, lubricate cartilage surfaces, and interrupt the pain-inflammation cycle. The clinical benefit of any joint injection is directly tied to accurate needle placement within the joint capsule — something landmark-based injection alone cannot guarantee.
At Silver Spring Medical Center, Dr. Grossman performs all joint injections under real-time fluoroscopic or ultrasound guidance, using contrast confirmation (fluoroscopy) or direct needle visualization (ultrasound) to ensure intra-articular placement before any medication is delivered.
Joints Treated
- Knee (tibiofemoral, patellofemoral)
- Hip (femoroacetabular joint)
- Glenohumeral shoulder joint
- Acromioclavicular (AC) joint
- Sacroiliac (SI) joint
- Elbow joint
- Ankle (tibiotalar)
- Wrist (radiocarpal)
Injectate Options
- Corticosteroid: Rapid anti-inflammatory relief; 1–3 month duration
- Hyaluronic Acid (Viscosupplementation): Knee OA lubrication; series of 1–5 injections
- PRP (Platelet-Rich Plasma): Biologic regenerative option; leucocyte-rich for inflammatory arthropathy
- Dextrose Prolotherapy: Stimulates ligamentous and capsular healing
Conditions Addressed
- Osteoarthritis (mild, moderate, severe)
- Inflammatory arthritis (RA, PsA, crystal arthropathy)
- Adhesive capsulitis (frozen shoulder)
- Joint effusion and synovitis
- SI joint dysfunction and sacroiliitis
Guidance Choice
- Ultrasound: Real-time soft-tissue visualization; preferred for shoulder, hip, elbow, wrist
- Fluoroscopy: Contrast confirmation within joint; preferred for hip, SI joint, ankle when anatomy is complex
- Both modalities available at SSMC — selected based on joint, anatomy, and clinical goal
