Complete eradication of periprosthetic joint infection is achieved by resection of all components without reimplantation through arthrodesis or above-the-knee-amputation. While amputation may be unpopular with patients it provides a greater ability to reconstruct, with an external prosthesis, a functioning joint. 1.
What is this special issue on periprosthetic joint infection about?
This special issue on periprosthetic joint infection discusses important details in the diagnostic and therapeutic procedures.
How is acute periprosthetic joint infection (PJI) treated?
In conclusion, DAIR is the obvious choice for treatment of acute PJI, with good success rates in selected patients. Core tip: Acute periprosthetic joint infection (PJI) is a major complication after total joint arthroplasty, and occurs either postoperatively or via hematogenous spreading.
What are the treatment options for acute periprosthetic infections?
Irrigation and débridement and prosthesis retention for treating acute periprosthetic infections. Clin Orthop Relat Res. 2010;468:2024–2028. [PMC free article][PubMed] [Google Scholar] 51. Estes CS, Beauchamp CP, Clarke HD, Spangehl MJ.
How is periprosthetic joint infection diagnosed?
Periprosthetic joint infection is diagnosed, if ⩾ 1 criterion is fulfilled. The most important PJI classification is based on the time since primary onset of the symptoms ( Table 2 ). This directly suggests the maturation stage of the present biofilm and is crucial in choosing the optimal treatment strategy. Table 2.
How do you treat periprosthetic joint infection?
In the United States, chronic PJI has been mainly treated via two-stage exchange arthroplasty with a 4 to 8 week course of IV antibiotics in between the two stages. However, this surgical strategy is now described as initial treatment for some acute postoperative or acute hematogeneous PJI.
Is treatment of periprosthetic joint infection improving over time?
Conclusion: Despite the increasing clinical focus, research advances, and growing literature relating to PJI, we were unable to detect any substantial improvement in the treatment success rates of PJI at our institution over the 17 years examined in this study.
What is prosthetic joint infection?
Prosthetic joint infection (PJI), also referred to as periprosthetic infection, is defined as infection involving the joint prosthesis and adjacent tissue.
What is the optimal irrigation solution in the management of periprosthetic hip and knee joint infections?
Treatment of periprosthetic joint infection using antimicrobials: dilute povidone-iodine lavage.
What antibiotics treat knee infection?
Based on the results in this study, monotherapy with linezolid or TMP/SMX, and rifampin in combination with TMP/SMX rather than fusidic acid or quinolone, would be an appropriate treatment for patients with bone and joint infections, especially in cases of suspected MRSA.

What is the DARE procedure?
Debridement Antibiotics and Implant Retention(DAIR) is a procedure to treat a periprosthetic joint infection(PJI) after Total Hip Arthroplasty(THA) or Total Knee Arthroplasty(TKA). The timing between the primary procedure and the DAIR is likely a determinant for its successful outcome.
How do you treat a septic joint?
Quick treatment with antibiotics is needed to halt the risk of joint damage. Other treatments include medicines for pain and fever, drainage of the joint, physical therapy, and a splint.
How is prosthetic joint infection diagnosed?
A diagnosis of prosthetic joint infection usually begins with a physical exam and review of your symptoms. If a PJI is suspected, your physician may also order: Blood tests: Blood samples will be taken to look for increased white blood cell count (indicating infection) and other indicators of inflammation in the body.
What is the standard procedure for acute infection?
Standard procedure in acute infection is debridement, irrigation, change of mobile parts and retention of the prosthesis. Outcome of this less invasive procedure is described controversially. However, trials qualifying and treating the patients according to the proposed algorithm show very good outcome.
What is the ability to grow and persist on the implant surface and on necrotic tissue in the form of a
The ability to grow and persist on the implant surface and on necrotic tissue in the form of a biofilm represents a basic survival mechanism by which micro-organisms resist environmental factors.8After the first contact with the implant, micro-organisms immediately adhere to its surface.
How long does it take for a PJI to manifest?
Around two thirds of PJI cases are caused through intra-operative inoculation of micro-organisms.3Depending on microbial virulence, PJI can manifest either early (within the first four weeks after implantation) or with a delay (typically between three months and three years).
Can prosthetic joints be seeded?
All prosthetic joints remain susceptible to haematogenous seeding from a distant primary focus during their entire indwelling time. High vascularity of periprosthetic tissue exposes the prosthesis to the highest risk of haematogenous infection in the first years after implantation.
What is a periprosthetic joint infection?
Periprosthetic joint infection (PJI) is a devastating complication after total joint arthroplasty, occurring in approximately 1%-2% of all cases. With growing populations and increasing age, PJI will have a growing effect on health care costs. Many risk factors have been identified that increase the risk of developing PJI, including obesity, ...
What is the best treatment for acute pji?
DAIR treatment is probably the most widely performed initial treatment option for acute PJI, although the exact data on the number of such procedures performed is yet unknown. When acute PJI is suspected (or confirmed by the previously mentioned criteria) a debridement procedure should be performed as soon as possible, meanwhile keeping in mind that patient health optimization should also be maintained. For example, it has been seen that factors such as hyperglycemia and malnutrition adversely affect outcome after total joint surgery [ 41, 42 ].
What is a PJI?
Periprosthetic joint infection (PJI) is a devastating complication after total joint arthroplasty, occurring in approximately 1%-2% of all cases. With growing populations and increasing age, PJI will have a growing effect on health care costs. Many risk factors have been identified that increase the risk of developing PJI, including obesity, immune system deficiencies, malignancy, previous surgery of the same joint and longer operating time. Acute PJI occurs either postoperatively (4 wk to 3 mo after initial arthroplasty, depending on the classification system), or via hematogenous spreading after a period in which the prosthesis had functioned properly. Diagnosis and the choice of treatment are the cornerstones to success. Although different definitions for PJI have been used in the past, most are more or less similar and include the presence of a sinus tract, blood infection values, synovial white blood cell count, signs of infection on histopathological analysis and one or more positive culture results. Debridement, antibiotics and implant retention (DAIR) is the primary treatment for acute PJI, and should be performed as soon as possible after the development of symptoms. Success rates differ, but most studies report success rates of around 60%-80%. Whether single or multiple debridement procedures are more successful remains unclear. The use of local antibiotics in addition to the administration of systemic antibiotic agents is also subject to debate, and its pro’s and con’s should be carefully considered. Systemic treatment, based on culture results, is of importance for all PJI treatments. Additionally, rifampin should be given in Staphylococcal PJIs, unless all foreign material is removed. The most important factors contributing to treatment failure are longer duration of symptoms, a longer time after initial arthroplasty, the need for more debridement procedures, the retention of exchangeable components, and PJI caused by Staphylococcus ( aureus or coagulase negative). If DAIR treatment is unsuccessful, the following treatment option should be based on the patient health status and his or her expectations. For the best functional outcome, one- or two-stage revision should be performed after DAIR failure. In conclusion, DAIR is the obvious choice for treatment of acute PJI, with good success rates in selected patients.
What is PJI in a prosthetic?
In their definition the diagnosis of PJI can be made if: (1) there is a sinus tract communicating with the prosthesis; or (2) a pathogen is isolated by culture from at least two separate tissue or fluid samples obtained from the affected prosthetic joint.
How successful is debridement for PJI?
Debridement, antibiotics and implant retention (DAIR), the primary treatment for acute PJI, should be performed as soon as possible after the development of symptoms, and has success rates around 60%-80%. Whether single or multiple debridement procedures are more successful remains unclear.
What is the success rate of PJI?
Success rates differ, but most studies report success rates of around 60%-80%.
Why use local antibiotics?
The rationale for using local antibiotic treatment is to achieve a high local concentration of antibiotic agents, thereby killing the causative microorganism, without the side-effects of high systemic concentrations. Beads are usually loaded with gentamicin, but vancomycin and tobramycin are also used.
What are the symptoms of periprosthetic joint infection?
Periprosthetic joint infections (PJIs) are classified as early (<3 months), delayed (3–24 months) and late (>2 years after surgery).1 In early infection, typical signs and symptoms include fever, shivering and tachycardia. In addition, local signs of postoperative wound infection such as erythema, warmth, a wet or gaping wound, as well as prolonged wound secretion are suspicious for surgical site infection. Early infections are mainly caused by Staph. aureus or Gram-negative bacilli. Delayed or low-grade infection is characterized by subtle or absent signs and symptoms. Persistent pain after implantation indicates inflammation and/or early loosening. This type of infection is mainly caused by low-virulence micro-organisms, such as coagulase-negative staphylococci and Propionibacterium acnes. Late infection is caused by hematogenous seeding. Hallmarks are sudden local joint pain due to inflammation or increasing pain due to loosening. The main sources of bacteremia are skin, respiratory tract, dental and urinary tract infection. 45 However, hematogenous infection can also occur after primary Staph. aureus sepsis without a detectable focus. 46
What are the most common microorganisms in periprosthetic shoulder?
Most frequent microorganisms: Staphylococcus aureus, coagulase-negative staphylococci and streptococci. Propionibacterium acnes: Most important microorganism in periprosthetic shoulder infection. Microorganisms establish a biofilm on the surface of the implant.
What is PJI in healthcare?
PJI is a potentially catastrophic problem that has significant health and financial burdens for the patient and the health care provider, respectively. The two most important factors to ensure successful outcomes are a multidisciplinary team approach and to have the treatment in an institution, which has the required expertise to deal with PJI.
What is PJI in surgery?
Periprosthetic joint infection (PJI) is one of the leading causes of failure following hip replacement surgery and places an immense physical and emotional burden on the patient and enormous financial pressures on society.
What is delayed infection?
Delayed or low-grade infection is characterized by subtle or absent signs and symptoms. Persistent pain after implantation indicates inflammation and/or early loosening. This type of infection is mainly caused by low-virulence micro-organisms, such as coagulase-negative staphylococci and Propionibacterium acnes.
How long to wait to discontinue antimicrobial therapy?
It is important to discontinue antimicrobial therapy at least 2 weeks prior tissue sampling for culture. 27 Since implant-associated infection involves microbial biofilms, the yield of implant culture may be higher than the one of tissue specimens.
What are the signs of postoperative wound infection?
In addition, local signs of postoperative wound infection such as erythema, warmth, a wet or gaping wound, as well as prolonged wound secretion are suspicious for surgical site infection. Early infections are mainly caused by Staph. aureus or Gram-negative bacilli.
