The Impact of use of Double Set-up on Infection Rates in Revision Total Knee Replacement and Limb Salvage Procedures (original) (raw)

The Effectiveness of Repeat Two-Stage Revision for the Treatment of Recalcitrant Total Knee Arthroplasty Infection

The Journal of Arthroplasty, 2018

Background: The gold standard method in North America for management of infected TKA is twostage revision Arthroplasty. This has provided a generally high success rate. However, persistent infection after two-stage revision knee arthroplasty does occur. The purpose of this study was to predict the success rate of second, two-stage revision arthroplasty. Methods: All infected TKA treated between 2000 and 2015 that were operated by a single senior surgeon were reviewed retrospectively. Patients were stratified according to general health and limb status according to the Musculoskeletal Infection Society (MSIS) scoring System. The reinfection rate in the last follow-up was identified. Chi-square and Fisher exact tests were used to compare binary variables. Results: We found a statistical relationship between the higher stage of MSIS score, type of microorganism, flap surgery and reinfection rate after reimplantation of second two-stage. There isn't any statistical significant correlation between the age, gender, constraint pattern of prosthesis, number of spacers and time interval between the first and second stages of second two-stage surgery with the numbers available in this study.

Outcome of Revision Surgery for Infection After Total Knee Arthroplasty

JBJS Reviews, 2019

Background: Periprosthetic joint infection (PJI) after knee arthroplasty surgery remains a serious complication, yet there is no international consensus regarding the surgical treatment of PJI. This study aimed to assess prosthesis survival rates, risk of revision, and mortality rate following different surgical strategies (1-stage versus 2-stage implant revision and irrigation and debridement with implant retention) that are used to treat PJI. Methods: The study was based on 644 total knee arthroplasties (TKAs) that were revised because of a deep infection (i.e., surgically treated PJI) and reported to the Norwegian Arthroplasty Register (NAR) from 1994 to 2016. Kaplan-Meier and multiple Cox regression analyses were performed to assess implant survival rate and risk of revision. We also studied mortality rates at 90 days and 1 year after revision for PJI. Results: During the follow-up period, 19% of the irrigation and debridement cases, 14% of the 1-stage revision cases, and 12% of the 2stage revision cases underwent a subsequent revision because of a PJI. The 5-year Kaplan-Meier survival rate with revision for infection as the end point was 79% after irrigation and debridement, 87% after 1-stage revision, and 87% after 2-stage revision. There were no significant differences between 1-stage and 2-stage revisions with subsequent revision for any reason as the end point (relative risk [RR], 1.7; 95% confidence interval [CI], 0.9 to 3.5) and no difference with revision because of infection as the end point (RR, 1.6; 95% CI, 0.7 to 3.7). In an age-stratified analysis, however, the risk of revision for any reason was 4 times greater after 1-stage revision than after 2-stage revision in patients over the age of 70 years (RR, 4.3; 95% CI, 1.3 to 14.8). Age had no significant effect on the risk of subsequent revision for knees that had been revised with the irrigation and debridement procedure. The 90-day and 1-year mortality rates after revision for PJI were 1.2% and 2.5%, respectively. Conclusions: Irrigation and debridement yielded good results compared with previous published studies. Although the 1-stage revisions resulted in a fourfold increase in risk of subsequent revision compared with the 2stage revisions in older patients, the overall outcomes after 1-stage and 2stage revisions were similar.

Results of 2-stage reimplantation for infected total knee arthroplasty

The Journal of Arthroplasty, 1998

Optimum treatment of the infected total knee arthroplasty has not been clearly established. To clarify the efficacy of two-stage reimplantation, experience with 66 infected total knee arthroplasties in 64 patients who had been treated with 2-stage reimplantation total knee arthroplasty between September I980 and October 1993 was reviewed. Of these, 55 knees in 54 patients were available for follow-up examinations at an average of 61.9 months (range, 28-146 months). The initial diagnoses were rheumatoid arthritis (14 knees) and osteoarthritis (41 knees). Reimplantation was successful in 80.0% of knees with low-virulence organisms (coagulase-negative Staphylococcus, Streptococcus), 71.4% with polymicrobial organisms, and 66.7% with high-virulence organisms (methicillin-resistant Staphylococcus aureus). Reimplantation was successful in 82 % of patients with osteoarthritis and in 54% of patients with rheumatoid arthritis (P = .024). The success rate was 92% if infection occurred after primary arthroplasty but only 41% if after multiple previous knee operations (arthroscopy, osteotomy, or revision total knee arthroplasty) (P < .001). Key words: two-stage reimplantation, infected total knee arthroplasty, virulence of microorganism, previous knee operations, rheumatoid arthritis.

Infection in revision total knee arthroplasty

Seminars in Arthroplasty, 2003

Total knee arthroplasty (TKA) is an accepted and successful treatment for advanced knee disease. TKA is being done at an increasing rate each year. Although long-term results following TKA are excellent, infection remains one of the main factors in producing a poor outcome. Infection following a TKA presents both a complex and difficult scenario for the physician. Early intervention with aggressive treatment has yielded the most favorable results with regard to treatment of infection and preservation of function. For most patients, two-stage revision arthroplasty maintains itself as the standard of care. This article discusses classification and diagnosis of infection as well as specific microbiologic pathogens responsible. The various different strategies in the treatment of infected TKA as well as salvage procedures are also reviewed. Understanding this topic will enable health care providers to give higher quality of care, allow for a reduction in modifiable risk factors and will aid containing overall health care costs.

Single-stage revision for the infected total knee replacement: results from a single centre

The Bone & Joint Journal, 2014

Peri-prosthetic infection is amongst the most common causes of failure following total knee replacement (TKR). In the presence of established infection, thorough joint debridement and removal of all components is necessary following which new components may be implanted. This can be performed in one or two stages; two-stage revision with placement of an interim antibiotic-loaded spacer is regarded by many to be the standard procedure for eradication of peri-prosthetic joint infection.

Modern Treatment of Infected Total Knee Arthroplasty With a 2-Stage Reimplantation Protocol

The Journal of Arthroplasty, 2010

The purpose of this study was to determine if 2-stage reimplantation for the treatment of infected total knee arthroplasty (TKA) is still effective for treating contemporary pathogens, many of which are multidrug resistant (MDR). The medical records of all cases of infected TKAs from April 1998 to March 2006 were retrospectively reviewed for data on infecting organism and success of treatment. Of 72 patients (75 knees), with a minimum of 2 years of follow-up, who completed the protocol, the infection was eradicated in 90.7% (68/75 knees). Thirty-one (91.2%) of 34 of MDR infections and 42 (91.3%) of 46 of non-MDR infections were successfully treated. These results support previous studies that demonstrated the effectiveness of a 2-stage reimplantation protocol with a standard 1:8 minimal bactericidal titer for treating infections after TKA, including MDR organisms.

Developing a strategy to treat established infection in total knee replacement: A review of the latest evidence and clinical practice

Journal of Bone and Joint Surgery - British Volume, 2012

This review summarises the opinions and conclusions reached from a symposium on infected total knee replacement (TKR) held at the British Association of Surgery of the Knee (BASK) annual meeting in 2011. The National Joint Registry for England and Wales reported 5082 revision TKRs in 2010, of which 1157 (23%) were caused by infection. The diagnosis of infection beyond the acute post-operative stage relies on the identification of the causative organism by aspiration and analysis of material obtained at arthroscopy. Ideal treatment then involves a two-stage surgical procedure with extensive debridement and washout, followed by antibiotics. An articulating or non-articulating drug-eluting cement spacer is used prior to implantation of the revision prosthesis, guided by the serum level of inflammatory markers. The use of a single-stage revision is gaining popularity and we would advocate its use in certain patients where the causative organism is known, no sinuses are present, the patient is not immunocompromised, and there is no radiological evidence of component loosening or osteitis.

Is Single-stage Revision According to a Strict Protocol Effective in Treatment of Chronic Knee Arthroplasty Infections?

Clinical Orthopaedics and Related Research®, 2014

Background The increasing number of patients experiencing periprosthetic total knee arthroplasty (TKA) infections and the cost of treating them suggest that we seek alternatives to two-stage revision. Single-stage revision is a potential alternative to the standard two-stage procedure because it involves only one surgical procedure, so if it is comparably effective, it would be associated with less patient morbidity and lower cost. Questions/purposes We compared (1) the degree to which our protocol of a highly selective single-stage revision approach achieved infection control compared with a two-stage revision approach to TKA infections; and (2) Knee Society scores and radiographic evidence of implant fixation between the single-stage and two-stage patients who were treated for more complicated infections. Methods Between 2004 and 2009, we treated 102 patients for chronic TKA infections, of whom 28 (27%) were treated using a single-stage approach and 74 (73%) were treated using a two-stage approach. All patients were available for followup at a minimum of 3 years (mean, 6.5 years; range, 3-9 years). The indications for using a single-stage approach were minimal/ moderate bone loss, the absence of immunocompromise, healthy soft tissues, and a known organism with known sensitivities for which appropriate antibiotics are available. Participants included 38 men and 64 women with a mean age of 65 years (range, 45-87 years).

Protocol for Treating Acute Infections in Cases of Total Knee Arthroplasty

Acta Ortopédica Brasileira, 2019

Objective: To retrospectively evaluate the results after applying a protocol for treating acute infections in cases of total knee arthroplasty and to establish factors predictive of success or failure. Methods: Thirty-two patients who were diagnosed with acute infection of the knee following total arthroplasty between 2004 and 2009 were retrospectively evaluated. Infections following arthroplasty were treated in accordance with the protocol for acute infections following arthroscopy recommended at our institution. Results: With application of a treatment protocol for acute infections following total knee arthroplasty, 26 patients (81.2%) had good results and 6 (18.8%) had unsatisfactory results. Statistical analysis showed that the variables correlated with a worse prognosis were age (p = 0.038) and number of surgical debridement procedures performed (p = 0.038). Conclusion: Our treatment routine was effective for infection. Prosthesis revision was performed in 2 cases when the init...

Infection after total knee arthroplasty

The Journal of Bone and Joint Surgery, 2004

The aim of our study was to determine the current incidence and outcome of infected total knee arthroplasty (TKA) in our unit comparing them with our earlier audit in 1986, which had revealed infection rates of 4.4% after 471 primary TKAs and 15% after 23 revision TKAs at a mean follow-up of 2.8 years. In the interim we introduced stringent antibiotic prophylaxis, and the routine use of occlusive clothing within vertical laminar flow theatres and 0.05% chlorhexidine lavage during arthroplasty surgery.
