Aspiration and Injection ofJoints and Soft Tissue Joseph J. Ruane, DO Medical Director, Musculoskeletal Health McConnell Heart Health Center Team Physician Columbus Blue Jackets
Goals • Key anatomy and landmarks • Practical review of techniques and pitfalls • Shoulder • Knee, including viscosupplementation • Lateral epicondyle • Soft tissue injection
Rheumatoid arthritis Gout Pseudogout Systemic lupus erythematosus and mixed connective tissue disease Acute traumatic arthritis Osteoarthritis Inflammatory bowel disease with peripheral joint involvement Shoulder periarthritis (adhesive capsulitis, or frozen shoulder) Conditions with peripheral joint manifestations (ankylosing spondylitis, psoriatic arthritis, and Reiter's disease) Tietze's syndrome Intra-articular Corticosteroids - Indications
Intra-articular CorticosteroidsContraindications Absolute Contraindications: • Overlying cellulitis or infected joint/bursa • Severe overlying dermatitis • Bacteremia • Allergy to any of the medications • Prosthetic joints Relative Contraindications: • Coagulation disorder • Uncooperative patient • Significant Obesity • Uncontrolled diabetes
Onset, Duration, and Toxicity of Local Anesthetics DrugOnsetDurationMax volume Lidocaine HCl 1% 1-2 min ~1 hr 20 mL 2% 1-2 min ~1 hr 10 mL Bupivacaine HCl 0.25% 30 min 8 hr 60 mL 0.5% 30 min 8 hr 30 mL
Injection Technique • If aspiration is not necessary, local anesthesia at the injection site may be omitted • A 22 or 25-gauge needle that is 1.25 to 1.5 inches long is appropriate • A 16- or 18-gauge needle is required to aspirate thick joint fluid or purulent exudate • Vapo-coolant spray (or similar) may be used prior to injection to decrease entry pain. Spray for 3-5 seconds and wait for fluid to evaporate before injecting
Injection Technique CARDINAL RULES ALWAYS – AWAYS ASPIRATE NEVER – NEVER – INJECT AGAINST RESISTENCE ALWAYS – ALWAYS – KNOW YOUR ANATOMY NEVER – NEVER – FORGET TO DISCUSS SIDE EFFECTS
Intra-articular Corticosteroids:Possible Sequela • Tendon rupture (<1%) • Calcification (up to 40%) • Post-injection flare of symptoms (2-5%) • Tissue atrophy • Fat necrosis • Erythematous flushing of skin (chest and face) • Skin depigmentation • Uterine bleeding • Nerve damage • Charcot-like arthropathy ("steroid arthropathy”) • Posterior subcapsular cataracts • Pancreatitis (rare) • Cushing's (rare) • Fluid retention • Osteonecrosis (rare) • latrogenic infection (rare)

Arthrocentesis and Injection of theKnee Technique and Pitfalls
“Corticosteroid Injections Safe for Knee Osteoarthritis” • 68 patients with knee OA • 34 patients each received triamcinolone acetonide or saline, every 3 months for 2 years • Neither group showed disease progression; changes in the mean joint-space width were not significant Ralnauld Je Buckland-Wright C, Ward R, et al, Safety and efficacy of long-term intraarticular steroid injections in osteoarthritis of the knee: a randomized, double-blind, placebo-controlled trial; Arthritis Rheum. 2003;48:370-377

Viscosupplementation Proposed Modes of Action: • Restoration of viscoelastic properties • “Normalization” of HA synthesis by synoviocytes • Anti-inflammatory effects • Analgesic effects

Confirmation of Joint Entry • Aspiration of joint fluid • Withdrawal of air bubbles • Contact with the articular cartilage • Water vapor in nozzle • Air injection
If You Are NOT in the Joint • Pain with initial fluid bolus • Resistance to injection • Visible expansion of soft tissue • Discomfort with leg extension or ambulation post injection
