II. Epidemiology

  1. Incidence: 2-10 per 100,000 cases/year (16,000) of Monoarticular Arthritis in the Emergency Department (U.S., 2018)
  2. Age
    1. Bimodal distribution peaks <15 years old and over 55 years old
    2. Young children <18-24 months are more susceptible to Septic Arthritis
      1. Bridging veins between metaphysis and epiphysis allow spread of infection to joint
      2. Bridging veins close after age 18-24 months

III. Causes

  1. See Septic Joint Causes
  2. Most common causes of Septic Joint
    1. Streptococcus
    2. Staphylococcus (including MRSA or Methicillin Resistant Staphylococcus Aureus)
      1. MRSA is associated with more severe infection and subperiostal abscess
    3. Gonorrhea is the most common cause of Septic Arthritis in young adults

IV. Risk Factors

  1. No risk factor present in up to 22% of cases
  2. Systemic comorbidity
    1. Immunosuppression
    2. HIV Infection
    3. Diabetes Mellitus

    5. Alcoholism
    6. Sickle Cell Anemia
    7. Elderly patients over age 80 years old
    8. Tobacco Abuse
  3. Joint disorders (47% of cases have previously deranged affected joint)
    1. Rheumatoid Arthritis (14% of cases)
      1. Higher mortality risk with Immunosuppressants (TNF agents, Systemic Corticosteroids)
      2. TNF agents predispose atypical and virulent infections (e.g. Salmonella, Actinobacillus, Listeria)
      3. Higher risk of Oligoarticular infection
    2. Osteoarthritis
    3. Inflammatory Bowel Disease
    4. Prosthetic joint (1-2% risk at 2 years, >2% at 10 years; nearly half occur in the first 3 months after surgery)
      1. Prosthetic Hip Joint
      2. Prosthetic Knee Joint
    5. Other Joint surgery
  4. Overlying skin disruption
    1. Chronic dermatitis

V. Pathophysiology

  1. Hematologic seeding in most cases from Occult Bacteremia
    1. Once joint seeding occurs, infection progresses rapidly
    2. Joint is susceptable to hematogenous spread
      1. Synovial lining lacks a protective basement membrane
    3. Sources
      1. Pneumonia
      2. Skin or soft tissue infection
      3. Pyelonephritis
  2. Other, less causes of joint infection
    1. Trauma
    2. IV Drug Abuse
    3. Iatrogenic Infection (e.g. Joint Injection, arthroscopy)

VI. Precautions

  1. Septic Arthritis has a high inpatient mortality (approaches 15%)
    1. Delayed diagnosis significantly increases morbidity and mortality
  2. Examination is unreliable in ruling out Septic Arthritis
    1. Poor reliability in distinguishing from Gouty Arthritis
    2. Crystals in Synovial Fluid does not exclude Septic Joint (actually increases its risk)
  3. Lab testing (outside of Joint Aspiration) is unreliable
    1. No lab value (e.g. CRP, ESR, WBC) outside of Joint Fluid examination excludes Septic Joint
  4. Joint infection leads to rapid joint destruction
    1. Inflammatory reaction directly associated with infection
    2. Intra-articular pressure with secondary vascular compromise
    3. Risk of permanent joint injury increases when appropriate Antibiotics are delayed >24-48 from onset
  5. Gout or Pseudogout exacerbation does NOT exclude Septic Arthritis
    1. Septic Arthritis occurs concurrent with gout or Pseudogout in 1.5 to 5% of cases

VII. Differential Diagnosis

  1. See Monoarticular Arthritis
  2. See Joint Pain Causes (Monoarticular)
  3. See Septic Joint Causes

VIII. History

  1. Fever (<60% of cases)
  2. Recent joint surgery
  3. Pain with joint range of motion
  4. Reduced ability to ambulate on affected joint (e.g. hip)
  5. Sexually Transmitted Disease exposures or history (especially Gonorrhea)

IX. Symptoms: Presentations in newborns

  1. Fever only present in 24-50% of cases
  2. Ill appearance
  3. Decreased use of the affected extremity

X. Findings: Signs and symptoms

  1. Rapid onset monoarticular joint inflammation
    1. Joint Pain with motion (Test Sensitivity 100%, but poor Specificity)
    2. Joint Swelling with effusion
    3. Joint warmth (unreliable)
    4. Joint erythema
    5. Significantly decreased joint range of motion (limited by pain)
    6. Significantly decreased weight bearing on infected joints
    7. Limb paralysis from inflammatory neuritis
    8. Joint with overlying Cellulitis (significantly increased risk of Septic Joint)
  2. Native Joints affected in Bacterial Infection
    1. Septic Arthritis is Polyarticular in 10-20% of cases (evaluate for endocarditis when multiple joints involved)
      1. Oligoarticular infection, often with fever, most commonly affects Shoulder, wrist and elbow
    2. Septic Knee (40-50% of cases)
    3. Septic Hip (15-20% of cases)
      1. Hip is most commonly affected joint in young children (40% of cases)
    4. Septic Shoulder (10-15% of cases, although some studies list 5%, more often associated with bacteremia)
    5. Septic Ankle (6-9% of cases)
    6. Septic Wrist (5-8% of cases)
    7. Septic Elbow (3-8% of cases)
  3. Joints affected with Intravenous Drug Abuse

    2. Sternoclavicular joint
    3. Symphysis Pubis
    4. Vertebral disc spaces (e.g. Spinal Epidural Abscess, Diskitis)

    2. Small joint infections
    3. Atypical infections (fungal infection, Lyme Disease, Tuberculosis)
    4. Immunosuppression

XI. Labs: General

  1. Precaution
    1. Arthrocentesis is the only accurate method to exclude Septic Arthritis
    2. However, do not delay Antibiotics for Arthrocentesis in ill or septic appearing patients (esp. children)
    3. None of these labs (CBC, ESR nor CRP) absolutely excludes Septic Arthritis at any level
      1. These labs may all be normal or even low despite Septic Arthritis
      2. Lab markers are useful as baseline to follow response to therapy
  2. C-Reactive Protein (C-RP)
    1. C-RP typically >20 mg/L in pediatric Septic Arthritis
      1. Test Sensitivity: 95% in children
      2. Closely mirrors infectious, inflammatory process
      3. Preferred serum marker in children (over ESR or Procalcitonin)
        1. Directs transition from IV to oral Antibiotics (when C-RP drops >50% from initial level)
    2. C-RP >2 mg/dl has Test Sensitivity >92% in adults
      1. Hariharan (2011) J Emerg Med 40(4): 428-31 [PubMed]
  3. Erythrocyte Sedimentation Rate (ESR)
    1. Children
      1. ESR typically > 25 mm/hour in pediatric Septic Arthritis
    2. Adults
      1. ESR >10 mm/hour (Test Sensitivity 98%) or ESR >15 mm/hour (Test Sensitivity 94%)
      2. Hariharan (2011) J Emerg Med 40(4): 428-31 [PubMed]
  4. Complete Blood Count
    1. WBC Count typically >12,000 in pediatric Septic Arthritis
  5. Other tests in severe cases or as directed by history
    1. Blood Culture
      1. Bacteremia is present in up to one third of cases of Septic Arthritis
      2. Obtain Blood Cultures (esp. in children) before starting Antibiotics
    2. Comprehensive Metabolic Panel
      1. Typically obtained in severe Septic Arthritis, to establish end-organ injury, Renal Dosing of Antibiotics
      2. May also evaluate Pseudogout
    3. Uric Acid
      1. Evaluate for gout in differential diagnosis
    4. STD Testing
      1. Gonorrhea (PCR from Urethra or Cervix, or Throat Culture)
      2. Syphilis
    5. Procalcitonin
      1. Procalcitonin >0.5 ng/ml has Positive Likelihood Ratio approaching 11
        1. Zhao (2017) Am J Emerg Med 35(8): 1166-71 [PubMed]

XII. Labs: Synovial Fluid Exam via Arthrocentesis

  1. Approach: Synovial Fluid Testing
    1. Synovial Fluid White Blood Cell Count
      1. Non-inflammatory Arthritis: 200-2000 White Blood Cells
      2. Inflammatory Arthritis: 2000 to 50,000 White Blood Cells
      3. Infectious Arthritis: >50,000 White Blood Cells (LR+ 3.6)
        1. However Exercise caution, as Septic Arthritis may occur at lower WBC Counts
    2. Synovial FluidGram Stain
      1. Falsely negative in 20-40% of Septic Arthritis patients
    3. Synovial Fluid culture
      1. Imperative to obtain (Gram Stain alone is insufficient)
      2. Best inoculated into Blood Culture medium (less contamination, better yield than solid plating)
    4. Synovial Fluid Crystal Exam
      1. Evaluates for the alternative, inflammatory Arthritis (e.g. gout, Pseudogout)
      2. However, crystalline Arthritis (e.g. gout) does not exclude Septic Joint
        1. Patients with underlying crystalline Arthritis are at a higher risk for Septic Joint
    5. Avoid Joint FluidGlucose and Protein (not useful)
    6. Synovial Fluid Lactate
      1. Lactic Acid >10 mmol/L consistent with Septic Arthritis
      2. Lactic Acid 5-10 mmol/L is suspicious for Septic Arthritis
  2. Bacterial Arthritis
    1. Opaque to turbid Synovial Fluid
    2. Synovial Fluid WBC
      1. Non-prosthetic joint: >50,000 White Blood Cells (or >90% PMNs)
        1. Likelihood Ratio: 4.7 for Septic Arthritis
      2. Prosthetic joint: >1700 White Blood Cells per mm3 (or >65% PMNs)
    3. Gram Stain
      1. Test Sensitivity: 29-60%
    4. Bacterial Culture
      1. Test Sensitivity: 30-50% (75% if Polyarticular)
      2. Guides Antibiotic therapy when positive
    5. Synovial lactate
      1. Synovial lactate >10 mmol/L has a very high Likelihood Ratio for Septic Arthritis (rules in Septic Arthritis)
  3. Gonococcal Arthritis
    1. Clear to opaque Synovial Fluid
    2. Synovial Fluid WBC: 30,000 to 100,000 (>80% PMNs)
    3. Gram Stain Positive in <25% of cases
    4. Culture positive in <50% of cases
    5. Also obtain other Gonorrhea testing (e.g. PCR from urine or Cervix, culture of Cervix, throat or Rectum
  4. Tuberculous Arthritis
    1. Opaque Synovial Fluid
    2. Synovial Fluid WBC: 10,000 to 20,000 (>50% PMNs)
    3. Gram Stain Positive in <20% of cases
    4. Culture positive in 80% of cases
  5. Prosthetic Joint
    1. Synovasure Lateral Flow Test
      1. Detects human alpha defensins released by activated Neutrophils
      2. Positive test suggestive of Bacterial periprosthetic infection

XIII. Imaging

  1. Joint Xray
    1. Early changes
      1. Distention of joint capsule
      2. Joint Dislocation
    2. Late changes
      1. Joint space destruction
      2. Epiphyseal cartilage resorption
      3. Metaphysis erosion
  2. Joint Ultrasound
    1. Bedside Ultrasound using high frequency linear probe (9-15 MHz)
    2. Identifies effusion
      1. Have patient move joint to distinguish effusion (re-distributes) from synovial thickening (static)
    3. Guides aspiration
      1. Especially helpful in Hip Joint evaluation and needle aspiration
      2. See Hip Ultrasound (Anterior Hip in Long Axis or LAX)
  3. Advanced imaging
    1. CT or MRI joint for unclear diagnosis
      1. Perform MRI with and without contrast to evaluate for Osteomyelitis and soft tissue involvement
      2. Consider MRI if poor clinical response in children after 96 hours
    2. CT-guided aspiration may also be considered if Ultrasound-guided aspiration results in dry tap

XIV. Imaging: Possibly Infected Prosthetic Joint

  1. Nuclear scan
    1. Negative Nuclear scan excludes septic prosthetic joint
  2. Pet Scan
  3. Avoid CT Scan or MRI in infected prosthetic joint
    1. Does not distinguish infected prosthetic joint from other causes of pain

XV. Management: General

  1. Obtain early Consultation
  2. Septic Arthritis management requires two components
    1. Thorough Joint Fluid drainage of purulent fluid
    2. Antimicrobial management to cover the causative organisms
    3. A third component, identifying Osteomyelitis (30% of cases), is key in children with Bacterial Arthritis
  3. Antibiotics are started after obtaining joint culture and Blood Culture
    1. See Septic Arthritis Causes for Antibiotic considerations
    2. Gram Stain of fluid may assist Antibiotic selection
    3. Empirically Antibiotics based on age and risk factors (see below) until culture results available
      1. Initial Antibiotic coverage for Gram Positive Cocci (Staphylococcus and Streptococcus)
      2. Additional Gram Negative coverage indications (if not otherwise directed by Gram Stain)
        1. Older age
        2. Immunosuppression
        3. Suspected bacteremia from genitourinary source

    4. Antibiotics do not need to be injected into joints
    5. Joint cultures are recommended before Antibiotics in most cases even if 24-48 hour Antibiotic start delay
      1. However do NOT delay Antibiotics in ill appearing children with suspected Bacterial Arthritis
    6. Antibiotics may be considered prior to Arthrocentesis in adults ONLY if
      1. Septic Shock (hemodynamically unstable) OR

      3. Consultant agrees that Antibiotics should be started before the culture has been obtained AND
      4. Procedure is delayed >24-48 hours
        1. Difficult Arthrocentesis requiring Intervention Radiology or rheumatology
  4. Intraarticular Anesthetic injection
    1. Consider at time of Arthrocentesis, after aspiration of diagnostic studies
    2. Ropivacaine (up to 3 mg/kg)
  5. Adjunctive Corticosteroids (only if directed by speciality care)
    1. Do not inject intraarticular Corticosteroids in suspected Septic Arthritis
    2. Discuss with consultant (orthopod)
    3. Associated with decreased duration and Disability in studies of pediatric Septic Arthritis
    4. Odio (2003) Pediatr Infect Dis J 22(10): 833-8 [PubMed]

    1. Difficult Joint Aspiration access (e.g. hip)
    2. Persistent fever and symptoms >24 hours
    3. Leukocytosis persists beyond 48 to 72 hours
    4. Repeat blood or joint cultures positive >48 hours
    5. Infected joint prosthesis
      1. Prosthesis may be salvaged if infection <1-2 weeks
        1. Many infected prostheses may still need to be removed
      2. Surgically debride the infection
      3. Treat with Parenteral combination Antibiotic therapy for 4 weeks (equivalent outcome to 6 week course)
        1. Use Rifampin as part of Antibiotic regimen
  5. Failed single joint washout risk factors
