==Overview==
The treatment for septic arthritis requires an adequate drainage of the joint fluid and appropriate antibiotic therapy.
Acute nongonococcal septic arthritis is a medical emergency which causes severe joint destruction and may increase both morbidity and mortality. So prompt diagnosis and treatment with antibiotic therapy and  prompt drainage which reduces long-term complications. '''[[Vancomycin]]''' is recommended as either empirical therapy for patients with [[Gram-positive cocci]] on a [[synovial fluid]] [[Gram stain]] or as a component of regimen for those with a negative [[Gram stain]] if [[MRSA|methicillin-resistant ''Staphylococcus aureus'' (MRSA)]] is prevalent.  If [[Gram-negative bacilli]] are observed, an anti-[[pseudomonal]] [[Cephalosporin]] (e.g., '''[[Ceftazidime]]''', '''[[Cefepime]]''') should be administered.  '''[[Carbapenems]]''' should be considered in conditions such as colonization or infection by [[ESBL|extended-spectrum β-lactamase]]–producing pathogens.  The optimal duration of therapy for septic arthritis remains uncertain. A minimum 3- to 4 week course is suggested for septic arthritis caused by ''[[S. aureus]]'' or [[Gram-negative bacteria]].  The use of [[Corticosteroids]] or intraarticular [[antibiotics]] is not advisable.<ref>{{Cite journal| doi = 10.1016/S0140-6736(09)61595-6| issn = 1474-547X| volume = 375| issue = 9717| pages = 846–855| last1 = Mathews| first1 = Catherine J.| last2 = Weston| first2 = Vivienne C.| last3 = Jones| first3 = Adrian| last4 = Field| first4 = Max| last5 = Coakley| first5 = Gerald| title = Bacterial septic arthritis in adults| journal = Lancet| date = 2010-03-06| pmid = 20206778}}</ref><ref name="pmid23591823">Sharff KA, Richards EP, Townes JM (2013) [https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&retmode=ref&cmd=prlinks&id=23591823 Clinical management of septic arthritis.] ''Curr Rheumatol Rep'' 15 (6):332.

Empiric therapy should be started after the collection joint fluid and blood sample for culture.
There are no indications for intra-articular antibiotic therapy.


==Medical Therapy==
==Medical Therapy==
Antibiotics are used to treat the infection and most of them achieve excellent bactericidal concentrations in the synovial fluid. The initial therapy depends on the clinical presentation, whether the patient is at risk for a Gonoccocal infection or not, and Gram stain of joint aspiration. The final therapy depends on the culture and sensitivity results. During the acute phase of the disease is important to keep the the joint still and raised, and the patient need to rest. Using cool compresses may help relieve pain. After the acute phase, exercise and physical therapy is important for the recovery process.  Severe cases may need surgery to drain the infected joint fluid.
Empiric treatment should be commenced as soon as possible after culture samples have been obtained. The choice of empiric antibiotics should be determined on the basis of:<ref name="pmid12364368">Shirtliff ME, Mader JT (2002) [https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&retmode=ref&cmd=prlinks&id=12364368 Acute septic arthritis.] ''Clin Microbiol Rev'' 15 (4):527-44.

Antibiotic selection and duration are determined according to the causative organisms and the surgical intervention performed.  Antimicrobial agent should achieve adequate tissue concentrations and be effective against slow-growing organisms and [[biofilms]]  in conformity with local antibiogram.  Liaison with microbiology services is recommended.  Empiric antibiotics may be required while culture results are pending and for the duration of treatment for culture-negative infection.  [[MRSA]] coverage with [[glycopeptide]] (e.g., [[Vancomycin]], [[Daptomycin]]) or [[Gram-negative]] coverage with [[Ceftriaxone]] should be considered when necessary.  Empiric or pathogen-directed antibiotic therapy is generally instituted following the procedure.<ref>{{Cite journal| issn = 1756-1833| volume = 338| pages = –1773| last1 = Matthews| first1 = Philippa C.| last2 = Berendt| first2 = Anthony R.| last3 = McNally| first3 = Martin A.| last4 = Byren| first4 = Ivor| title = Diagnosis and management of prosthetic joint infection| journal = BMJ (Clinical research ed.)| date = 2009| pmid = 19482869}}</ref>

The duration of antibiotic treatment varies depending on the surgical procedure undertaken. A six-week course of parenteral therapy is preferred if an infected [[prosthesis]] is retained, while two to four weeks of intravenous antibiotics may be sufficient if revision [[arthroplasty]] is performed. Oral antibiotics are commonly prescribed for three to six months in the setting of retained [[prosthesis]] compared with six weeks for revision [[arthroplasty]].<ref>{{Cite journal| issn = 1756-1833| volume = 338| pages = –1773| last1 = Matthews| first1 = Philippa C.| last2 = Berendt| first2 = Anthony R.| last3 = McNally| first3 = Martin A.| last4 = Byren| first4 = Ivor| title = Diagnosis and management of prosthetic joint infection| journal = BMJ (Clinical research ed.)| date = 2009| pmid = 19482869}}</ref>

Overview

Acute nongonococcal septic arthritis is a medical emergency which causes severe joint destruction and may increase both morbidity and mortality. So prompt diagnosis and treatment with antibiotic therapy and prompt drainage which reduces long-term complications. Vancomycin is recommended as either empirical therapy for patients with Gram-positive cocci on a synovial fluid Gram stain or as a component of regimen for those with a negative Gram stain if methicillin-resistant Staphylococcus aureus (MRSA) is prevalent. If Gram-negative bacilli are observed, an anti-pseudomonal Cephalosporin (e.g., Ceftazidime, Cefepime) should be administered. Carbapenems should be considered in conditions such as colonization or infection by extended-spectrum β-lactamase–producing pathogens. The optimal duration of therapy for septic arthritis remains uncertain. A minimum 3- to 4 week course is suggested for septic arthritis caused by S. aureus or Gram-negative bacteria. The use of Corticosteroids or intraarticular antibiotics is not advisable.[1][2]

Medical Therapy

Empiric treatment should be commenced as soon as possible after culture samples have been obtained. The choice of empiric antibiotics should be determined on the basis of:[3][4][5]

If the patient fails to respond to initial treatment, consider:[3]

  • Misidentification of causative pathogen
  • Infection with atypical pathogen
  • Concurrent osteomyelitis
  • Occult nidus of infection

Intra-articular antibiotics are not useful as it may increase infection rate and also causes chemical synovitis and cartilage toxicity.[6]

Methicillin-resistant Staphylococcus aureus (MRSA)

Patient at high risk of methicillin-resistant Staphylococcus aureus (MRSA) include:[7][2]

  • Known MRSA colonization or infection
  • Recent hospitalization
  • Nursing-home resident
  • Presence of leg ulcers
  • Indwelling catheters

Drainage or debridement of the joint space should always be performed in septic arthritis caused by MRSA. A 3 or 4 week course of therapy with Vancomycin (15–20 mg/kg/dose IV every 8–12 hours in adults or 15 mg/kg/dose IV every 6 hours in children), Daptomycin (6 mg/kg/day IV every 24 hours in adults or 6–10 mg/kg/dose IV every 24 hours in children), Linezolid (600 mg PO/IV twice daily in adults or 10 mg/kg/dose PO/IV every 8 hours in children), Clindamycin (600 mg PO/IV every 8 hours in adults or 10–13 mg/kg/dose PO/IV every 6–8 hours in children), and Trimethoprim-Sulfamethoxazole (3.5–4.0 mg/kg PO/IV every 8–12 hours in adults) have been used with success. A prolonged treatment of 4 to 6 weeks may be required if the condition is complicated by osteomyelitis.[8][9]

Prosthetic joint infection

Management of prosthetic joint infection typically requires both surgical intervention and extended courses of antimicrobial therapy. Options of surgical approach include

The surgical decision should be made by orthopedic surgeon with specialty consultation, such as infectious disease or plastic surgery as necessary.[10]

Antibiotic selection and duration are determined according to the causative organisms and the surgical intervention performed. Antimicrobial agent should achieve adequate tissue concentrations and be effective against slow-growing organisms and biofilms in conformity with local antibiogram. Liaison with microbiology services is recommended. Empiric antibiotics may be required while culture results are pending and for the duration of treatment for culture-negative infection. MRSA coverage with glycopeptide (e.g., Vancomycin, Daptomycin) or Gram-negative coverage with Ceftriaxone should be considered when necessary. Empiric or pathogen-directed antibiotic therapy is generally instituted following the procedure.[11]

The duration of antibiotic treatment varies depending on the surgical procedure undertaken. A six-week course of parenteral therapy is preferred if an infected prosthesis is retained, while two to four weeks of intravenous antibiotics may be sufficient if revision arthroplasty is performed. Oral antibiotics are commonly prescribed for three to six months in the setting of retained prosthesis compared with six weeks for revision arthroplasty.[12]
