This update on musculoskeletal infection presents a review of infection-related articles from January 2018 through the present from English-language journals, located using the National Center for Biotechnology Information web site, with a special emphasis on periprosthetic infection. The additional sections will cover recent salient articles in the areas of spine, trauma, hand, and pediatrics.

In a recent analysis of the Medicare Inpatient Data Set from 2005 to 2015, the risk of periprosthetic joint infection was 1.09% for hips and 1.38% for knees at 5 years. This risk did not change significantly during this 10-year period. Therefore, because the demand for total joint arthroplasty is projected to increase substantially in the coming years, the incidence of periprosthetic joint infection is anticipated to scale up proportionally1.

Conversely, the risk of mortality after periprosthetic joint infection decreased significantly during the time frame studied. However, the 5-year survival for Medicare patients was only 67% for periprosthetic infection after total hip arthroplasty and 72% for periprosthetic infection after total knee arthroplasty1. This high mortality rate following periprosthetic infection was echoed in 2 other studies in which the 5-year mortality for patients with periprosthetic joint infection after undergoing total joint arthroplasty was 21.12% for those who underwent total hip arthroplasty2 and 21.64% for those who underwent total knee arthroplasty3. The reported 1-year mortality in these studies had an odds ratio of 3.58 for periprosthetic joint infection after total hip arthroplasty2 and 3.05 for periprosthetic joint infection after total knee arthroplasty3 compared with the national age-adjusted risk of mortality.

Included in the cost of health care and, in particular, periprosthetic infection is the cost of litigation. In a retrospective review of medical malpractice lawsuits in a 5-county area in the Northeast United States including 113 total joint surgeons, 27% (31 of 113) were named in at least 1 lawsuit. Infection was the top reason for such litigation, representing 26.5% of all lawsuits4.


Prevention of periprosthetic joint infection has been a topic of considerable interest4-6 with a focus on preoperative, intraoperative, and perioperative considerations. Optimization of patients’ comorbidities is important in the prevention of periprosthetic joint infection. In a meta-analysis study designed to determine the influence of a bariatric surgical procedure prior to arthroplasty, Li et al. found that a bariatric surgical procedure reduced short-term medical complications, length of stay, operative time, and short-term periprosthetic infection in the knees but not the hips. A bariatric surgical procedure did not reduce the long-term risk of infection or complications7. In a retrospective cohort, Castano-Betancourt et al. determined that patients with rheumatoid arthritis or ≥2 other defined comorbidities, such as diabetes and anemia, are at elevated risk for periprosthetic joint infection8. Previous work has demonstrated the importance of long-term glycemic control in the prevention of periprosthetic joint infection9. Recently, there has been interest in glucose control more proximate to a surgical procedure10. Concern has been raised with regard to dexamethasone administration in total joint arthroplasty in patients with diabetes. O’Connell et al. observed an association between dexamethasone administration and a significant increase in early postoperative blood glucose levels in patients with diabetes following total joint arthroplasty and advised that dexamethasone be used with caution in this population11. The association between preoperative dexamethasone and elevated postoperative blood glucose in patients with diabetes was confirmed in a separate study by Godshaw et al.; however, the study did not demonstrate a connection between dexamethasone and postoperative periprosthetic joint infection12.

The routine use of adjuvant antibiotic-laden cement in primary total joint arthroplasty has been called into question. In a meta-analysis, King et al. found that the use of antibiotic-laden cement did not reduce the risk of postoperative periprosthetic joint infection compared with regular cement but was associated with a significant increase in cost13.

Substantial attention has been dedicated to local irrigation solutions for the prevention of periprosthetic joint infection in primary total joint arthroplasty. In an in vitro study investigating commonly used solutions, Campbell et al. showed that the Dakin solution forms potentially toxic precipitates when mixed with hydrogen peroxide and chlorhexidine gluconate; the authors recommended that surgeons avoid mixing irrigation solutions in the wound during a surgical procedure14. Ernest et al. performed an in-depth, in vitro analysis to assess the efficacy of povidone-iodine, chlorhexidine, hydrogen peroxide, the Dakin solution, and chlorine dioxide in reducing adherent Staphylococcus aureus colonies on common orthopaedic materials. The authors showed that the most effective solutions were hydrogen peroxide, with a 97% reduction in colony-forming units (CFU)/cm2, and povidone-iodine, with a 98% reduction in CFU/cm2. However, these solutions did not eliminate bacteria completely, and the authors recommended continued pursuit of adjuvants to eliminate adherent bacteria during irrigation and debridement for periprosthetic joint infection15.

Efficiency and cleanliness in the surgical environment are critical for economic and clinical success in arthroplasty. Two studies demonstrated that prolonged surgical time is associated with the development of infection after total joint arthroplasty16,17. In another study addressing the effect of the operating room environment on periprosthetic joint infection, Vijaysegaran et al. showed that space suits are associated with increased particle and microbiological emission rates in a simulated operating room compared with standard operating room attire, calling into question the safety of routine space suit use during total joint arthroplasty18.

Antimicrobial Treatment

Oral Antibiotics in Arthroplasty

A randomized controlled trial did not show that preoperative doxycycline reduced the prevalence of Cutibacterium acnes (formerly Propionibacterium acnes) on the skin and in the deep tissues at the time of periprosthetic joint implantation19. Debridement, antibiotics, and implant retention followed by chronic oral antibiotic suppression for acute total knee arthroplasty periprosthetic joint infection produced a 5-year infection-free survival of 66% in 1 small single-center study that lacked a control group20. A retrospective cohort study found that oral antibiotic prophylaxis for 7 days after a primary total knee arthroplasty or total hip arthroplasty in patients deemed at high risk for periprosthetic joint infection lowered the risk of periprosthetic joint infection21. However, the authors did not have a control group of high-risk patients and thus recommended the need for further study before widespread adoption of this protocol.

Topical Vancomycin

Two meta-analyses evaluating the effect of intrawound vancomycin in spinal surgery found that the groups treated with vancomycin had a significantly lower risk of surgical site infection22,23. Two single-center studies demonstrated a lower rate of surgical site infection in patients who underwent primary arthroplasty with the use of intrawound vancomycin powder24,25. However, both studies were retrospective studies with historical controls. One of these studies24 was confounded by the concomitant use of a povidone-iodine solution, and both authors noted the need for further study. One other study demonstrated an increased rate of sterile wound complications in the vancomycin group26. These authors recommended against the use of vancomycin powder, stating that higher-powered studies were needed to demonstrate its efficacy.

Animal studies contributed to knowledge regarding the use of topical vancomycin. In a rat model of open contaminated fractures, reduced bacterial growth was observed in both antibiotic bead and vancomycin powder groups when compared with a control group who underwent debridement alone. There were no significant differences between the antibiotic bead and vancomycin powder groups27. In a rabbit model with fixation implants seeded with methicillin-resistant S. aureus (MRSA), the application of intraoperative vancomycin powder at the time of fixation decreased the risk of bone infection and biofilm formation28.

Given the retrospective, uncontrolled study designs and conflicting results, the issue of whether topical vancomycin is beneficial in preventing surgical site infection remains unresolved.

Antibiotic Complications

There were several reports of complications of antibiotic use in orthopaedic patients, including red man syndrome and drug-induced linear immunoglobulin A (IgA) bullous dermatosis after the routine use of vancomycin-loaded bone cement29,30. Acute kidney injury requiring dialysis to lower toxic tobramycin levels after receipt of a vancomycin and tobramycin-impregnated cement spacers has also been reported31. A database review of 83,806 patients who underwent revision total knee arthroplasty due to periprosthetic joint infection found a 1.0% incidence of a Clostridioides difficile (formerly Clostridium difficile) infection after a revision total knee arthroplasty. A diagnosis of C. difficile infection was associated with longer length of stay, higher costs, and greater in-hospital mortality32.

Intra-Articular Antibiotics

One study assessed local, plasma, and urine concentrations of a gentamicin or vancomycin-loaded mineral composite antibiotic carrier and found a low plasma concentration and high local concentration of both antibiotics. The results also indicated that a deep surgical drain may decrease the amount of antibiotic available for systemic absorption33. A small prospective study evaluated the concentrations of gentamicin and vancomycin from antibiotic-impregnated spacers in 2-stage revision arthroplasty, as well as in vitro. The antibiotic concentration in spacer cement decreased rapidly in vitro within the first 24 hours, but in vivo, antibiotics were present much longer in tissues34. Work on an improved antibiotic delivery system using a layer-by-layer technique to load gentamicin on nanoparticles blended into the powder of bone cement demonstrated longer antimicrobial activity when compared with control cement specimens35.

Antibiotic Prophylaxis for Dental Procedures

In a survey of antibiotic-prescribing practices of dentists, 39% of respondents identified the presence of a prosthetic joint as a high-risk condition that required antibiotic prophylaxis. The dentists included in the survey reported greater antibiotic use than currently recommended by existing guidelines36.

Diagnosis of Periprosthetic Joint Infection

Synovial Biomarkers

Renz et al.37 reported on a point-of-contact lateral flow test for synovial alpha-defensin that showed a sensitivity of 54% to 84% depending on the criteria defined by 3 different infection organizations. They concluded that, given the limited sensitivity and high specificity, this test should be used as a confirmatory test rather than as a screening test. Gehrke et al. also compared the accuracy of the laboratory-based quantitative enzyme-linked immunosorbent assay (ELISA) alpha-defensin test with the point-of-contact lateral flow test and found no significant difference in the diagnostic accuracy38. They also reported improved results using a similar methodology (n = 223), with a sensitivity of 92.1% and a specificity of 100%. In a systematic review and meta-analysis, Marson et al.39 noted that the point-of-contact lateral flow test had a lower pooled sensitivity (85%) than the laboratory-based alpha-defensin test pooled sensitivity (95%). The authors believed that these lower pooled results for the lateral flow test were only comparable with the leukocyte esterase test and that further study was necessary prior to widespread adaption.

The alpha-defensin biomarker has some limitations in certain cases. Stone et al.40 showed that alpha-defensin in combination with synovial C-reactive protein (CRP) had a high sensitivity for a periprosthetic joint infection diagnosis, but had false-positive results in the presence of metallosis or false-negative results in the presence of low-virulence organisms. Another group confirmed that alpha-defensin is prone to false-positive results in the presence of an adverse local tissue reaction41.

Molecular Diagnosis and Sonication

Technical advances have decreased the cost of the molecular diagnosis of periprosthetic joint infection. Tarabichi et al.42,43 reported on the use of next-generation sequencing to identify pathogens in synovial fluid and tissue. They showed that cultures were positive in only 61% when compared with next-generation sequencing that identified a pathogen in 89.3% of the infected cases. However, next-generation sequencing also identified microbes in 25% of aseptic revisions with negative cultures and in 35.3% of primary total joint arthroplasties. Therefore, despite the increased yield of identifying pathogens in culture-negative cases, the identification of pathogens in what are currently identified as aseptic cases is a source of concern and needs further research. Similarly, Moshirabadi et al.44 reported on the use of polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) techniques to diagnose periprosthetic joint infection. They compared PCR-RFLP with cultures and found a sensitivity of 97.4% and a specificity of 100% for PCR-RFLP compared with a sensitivity of 31.6% and a specificity of 100% for cultures. In contrast, in another related study using PCR, Fink et al.45 reported limited operative characteristics of PCR in the diagnosis of periprosthetic joint infection, with a limited sensitivity of 55.6% and a specificity of 82%. However, the PCR techniques varied widely between studies, which can alter the number of false positives when standard PCR techniques are used. Another study showed that PCR results may vary depending on the source: synovial fluid compared with tissue or implant sonication. Sonicated fluid had the best diagnostic accuracy46.

Reimplantation Criteria

The diagnosis of persistent periprosthetic joint infection after the placement of a cement spacer is challenging with minimal tools available to measure it. Kanwar et al.47 reported the potential use of alpha-defensin in combination with Musculoskeletal Infection Society criteria to predict the success of reimplantation. However, in 27 patients who had negative alpha-defensin results prior to reimplantation, 3 (11%) had a recurrent infection within 1 year.


Published research in 2018 continues to clarify the role of each of the 3 major treatment options for periprosthetic joint infection: irrigation and debridement, 2-stage exchange, and 1-stage exchange.

Irrigation and Debridement

Irrigation and debridement with retention of components continued to show a high failure rate of 57% in a multicenter study for periprosthetic joint infection after total knee arthroplasty at 4 years48. Patients treated with irrigation and debridement with polyethylene exchange for periprosthetic joint infection within 2 weeks of the index arthroplasty had higher success rates (82%) when compared with those treated beyond 2 weeks (50%)49.

Two-Stage Exchange

It is often assumed that 2-stage treatment is very successful. However, a recent study questioned the validity of that assumption. In a study of 80 patients who underwent a 2-stage procedure, 14 (17.5%) never underwent reimplantation, 24 (30%) had a serious complication, and of the 66 patients with a successful reimplantation, only 48 (73%) remained infection-free50. Additionally, 9 (11%) of 80 patients required a spacer exchange for persistent infection, 3 of whom underwent eventual failure. Spacer exchange due to persistent infection is not uncommon, occurring in 59 of 3,417 patients in another study, one-third of whom became reinfected within 5 years compared with one-fifth of patients without an interim spacer51. Similarly, if a 2-stage hip procedure fails requiring a repeat 2-stage hip procedure, a reinfection rate of 42% (8 of 19) was noted in a series of 19 patients52.

The optimal timing for reimplantation following placement of an antibiotic-loaded spacer remains elusive. Predicting which patients are at risk for failed treatment remains difficult. In a study of 205 patients who underwent a 2-stage procedure, 27% (56 of 205) had a recurrent periprosthetic joint infection. Failure was 1.8 to 2.5 times more likely if the preoperative synovial fluid white blood cell count was >60,000, a neutrophil percentage of >92%, or an erythrocyte sedimentation rate (ESR) of >99 mm per hour53. In a review of 81 infected knees, another group noted an 88% success rate at 4 years. They noted poor diagnostic values of ESR and CRP but found a frozen section to have a sensitivity of 90%, making it a good indicator of success or failure at the time of reimplantation50.

Articulating antibiotic spacers appear to be safe for interim treatment. In a series of 135 hips undergoing a 2-stage procedure with an articulating spacer, an 88% infection-free survivorship at 5 years was noted54. In another study, 23 patients underwent a temporary 2-stage knee revision using an articulating spacer made of a loosely cemented primary implant; of these patients, 1 patient died, 13 patients underwent re-revision, and, in 9 patients, the implant remained in situ. No infections were noted at a 3.5-year follow-up55.

The importance of treatment consolidation at a tertiary center was highlighted in a study regarding patients referred to a tertiary center after resection arthroplasty and placement of an antibiotic spacer. A high rate of retained foreign material was noted, requiring re-debridement in which persistently positive cultures were present in 41% of cases56.

Two-stage treatment with high-dose antibiotic spacers can result in nephrotoxicity. Serum antibiotic levels were collected in 21 patients with such spacers57. Systemic accumulation of antibiotics persisted for at least 8 weeks, and, thus, patients should be monitored for complications related to systemic absorption of antibiotics postoperatively.

Although the results of culture-negative periprosthetic joint infections after total hip arthroplasties were similar when compared with culture-positive infections58, polymicrobial and fungal infections are much more challenging to treat. Polymicrobial infections were associated with significantly lower treatment success compared with single-organism infections59, and the overall success for fungal infections at 5 years was 29% for irrigation and debridement and 46% for 2-stage exchange60. Acute kidney injury requiring dialysis to lower toxic tobramycin levels after spacer placement has been reported31.

One-Stage Exchange

However, in a recent European study of 22 patients using antibacterial hydrogel-coated implants, 1-stage treatment showed results at 2.5 years that were similar to a 2-stage group without a coating61. Additionally, as noted previously, a decision-tree analysis found greater health utility while being more cost-effective when a 1-stage treatment strategy was utilized62.


Although magnetic resonance imaging (MRI) remains the most common radiographic technique for diagnosis of infection of the native spine, a fluorodeoxyglucose positron emission tomography (PET) scan may offer similar sensitivity and specificity and allows for the evaluation of sites of metastatic infection63. There appears to be a high degree of concordance between blood and spine biopsy cultures, not only in patients with S. aureus bloodstream infection and infection of the native spine, but also in those in whom the infection involves other organisms64. Among patients who require operative intervention for spinal infection, the ideal operative strategy is uncertain. A single-stage posterior approach or a 2-stage anterior and posterior approach was associated with similar clinical outcomes in patients with bacterial infection65. A single-stage approach may also be an option for selected patients with an infection due to Mycobacterium tuberculosis66-68 and Brucella species69.

Although infection associated with spinal instrumentation infection occurs most often in the first 3 months after the surgical procedure70, the consequences of deep infection may be long-lasting. An observational cohort study found that spinal instrumentation infection was an independent risk factor for unsuccessful fusion after instrumented lumbar spine surgery, resulting in a >12-fold increase in risk of unsuccessful fusion71. The accurate identification of patients at high risk for infection after spinal instrumentation remains difficult. A previously published prediction model performed poorly in a subsequent study72, and the Revised Cardiac Risk Index demonstrated an inferior discriminative ability compared with the American Society of Anesthesiologists (ASA) score73. A large cohort study of patients with S. aureus infection after spinal instrumentation demonstrated a failure rate of 36% for revision procedures to eradicate the infection. Debridement with retention of the implants and infection with MRSA were independently associated with treatment failure, and the use of rifampin-based combination therapy had a protective effect74.


Although infection after fracture fixation is a feared complication, a systematic review found no standardized definition, which hampers the study of this problem75. The risk of infection after fracture fixation is higher than that of infection following elective clean orthopaedic surgery, with rates of infection after fracture fixation ranging from 2% to 8% after operative fixation of an ankle fracture76,77, a high-energy femoral fracture78, and a closed tibial plateau fracture79. Reported risk factors for infection after fracture fixation were similar to those previously reported, including obesity76,77,79, diabetes76, open fracture76,77, high ASA score76, high-energy mechanism of fracture76,77, prolonged surgical duration79, smoking79, increased age77, and lack of antimicrobial prophylaxis76. In a retrospective study that used propensity score analysis, the ultimate rate of fracture union did not differ between patients treated with primary intramedullary nailing compared with a 2-stage approach initially using external fixation for high-energy femoral fractures78.


Any open fracture presents a risk for infection. However, a systematic review found that the infection rate for upper-extremity open fractures is lower than that commonly reported for lower-extremity open fractures80. The authors concluded that prompt administration of empiric antimicrobials and urgent debridement and treatment of open upper-extremity fractures are both important components to prevent infection. A prospective cohort study of hand infections requiring operative intervention found that patients with diabetes were more likely to have deep infections, require repeat intervention, and require eventual amputation, compared with patients without diabetes81. A 4-year, single-center, cohort study of flexor tenosynovitis observed that staphylococcal and streptococcal infection predominated, and 90% of patients required >1 surgical debridement82. Among patients with upper-extremity nontuberculous mycobacterial infections, outcomes were similar between immunocompetent patients and immunocompromised patients, and a delay of diagnosis of >4 months was associated with a more than fourfold risk of treatment failure83.


A multicenter, retrospective study of infections of the native spine in pediatric patients found that S. aureus was the most common pathogen, but that Kingella kingae continues to be important among patients who are 6 months to 4 years of age84. The risk of osteoarticular infection with K. kingae, a commensal organism in the oropharynx of young children, was significantly associated with the incidence of human rhinovirus infection, but not other community respiratory viral infections, supporting a postulated pathophysiologic mechanism85. Compared with children with methicillin-susceptible S. aureus (MSSA) infection, children with MRSA osteoarticular infection have more surgical procedures, more complications, longer hospital stays, and more frequent intensive care unit admissions86,87. Dexamethasone may have a role as an adjunctive therapy for pediatric septic arthritis, based on a meta-analysis of 3 randomized controlled trials and 1 cohort study88.


The prevention, diagnosis, and treatment of musculoskeletal infection remain challenging. Preoperative patient optimization and vigilance with regard to sterile technique are essential components of infection prevention. A high index of suspicion for the possibility of infection is critical when a patient with painful musculoskeletal symptoms presents, and the appropriate use of the currently available diagnostic tools is important for the clinician to fully understand. Prompt intervention using evidence-based treatment guidelines should maximize results.

Evidence-Based Orthopaedics

The editorial staff of The Journal reviewed a large number of recently published studies related to the musculoskeletal system that received a higher Level of Evidence grade. In addition to articles cited already in this update, 4 other articles with a higher Level of Evidence grade relevant to musculoskeletal infection are appended to this review after the standard bibliography, with a brief commentary about each article to help guide your further reading, in an evidence-based fashion, in this subspecialty area.

J Arthroplasty. 2018 Aug;33(8):2582-7. Epub 2018 Mar 27.

Irrigation and debridement is a commonly used treatment for acute periprosthetic joint infection; however, results are variable. A risk score was developed to predict the success of irrigation and debridement in periprosthetic joint infection, consisting of renal failure, cirrhosis, the index surgical procedure, a cemented prosthesis, and a CRP of >115 mg/L. However, it had an area under the curve of only 0.64; in comparison, the original study describing this risk score had an area under the curve of 0.84. Unfortunately, an instrument to consistently predict outcomes in a procedure that has variable results remains lacking.

The purpose of this study was to evaluate the practice of injecting saline solution into an aspirated joint that initially was without fluid. Using intraoperative tissue cultures as the gold standard for infection, for 313 wet aspirations, the sensitivity was 81% and the specificity was 90%; saline solution-injected dry aspirates had 81% sensitivity and 79% specificity. The sensitivity of dry taps is surprising in light of the conventional belief that injecting saline risks contamination and that joints without fluid are rarely infected.

This study evaluated a more comprehensive definition of periprosthetic joint infection using 11 different diagnostic variables. Assigning points to each variable, they found that the new definition correlated 100% with the current major criteria from the Musculoskeletal Infection Society definition of periprosthetic joint infection. Concerns about complexity, the availability of alpha defensin, and the weighting of individual variables will limit widespread acceptance of this definition.

Cell counts and polymorphonuclear cell percentages are sensitive methods for diagnosing periprosthetic joint infection. Although polymorphonuclear percentages are similar between hips and knees, the cutoff levels for cell counts may be somewhat different. The best cutoff levels for all patients with periprosthetic joint infection were 2,500 leukocytes/µL and a polymorphonuclear percentage of 66%. Elevated cell counts with a high percentage of polymorphonuclear cells have been a useful to diagnose periprosthetic joint infection. Although multiple attempts have been made to determine an exact cutoff, such efforts should be used only as a general guide without a focus on an exact number.
