Abstract
We sought to assess the current literature to present a comprehensive summary of the incidence, common pathogens, and risk factors for infection after anterior cruciate ligament (ACL) reconstruction. PubMed, CINAHL, EMBASE, and Scopus databases were searched for relevant studies reporting on infection after ACL reconstruction. Two reviewers independently screened the extracted studies for adherence to inclusion and exclusion criteria. Studies were selected if they reported on the incidence of infection, pathogens cultured from infected knees, or risk factors for infection after primary ACL reconstruction. Exclusion criteria consisted of studies with fewer than 100 patients or studies that included revision ACL reconstruction. Fifty studies met the inclusion and exclusion criteria, reporting on a total of 316,214 ACL reconstructions. Included studies evaluated between 123 and 104,255 patients. The overall incidence of infection was 0.60% (0.15-2.44%). The most common pathogens were Staphylococcus aureus, S. epidermidis, and coagulase-negative Staphylococci. Five studies reported that the use of hamstring autograft was a statistically significant risk factor for infection after ACL reconstruction, thus making hamstring autograft the most commonly reported risk factor. Other reported risk factors included male sex, use of immuno-suppressive medications or intraarticular steroid injections, prior knee surgery, and diabetes. Systematic review of the literature revealed that infection after ACL reconstruction remains an infrequent event with an incidence of 0.60% (0.15-2.44%). Furthermore, the most common pathogens are from the Staphylococcus genus of bacteria, comprising 84% of all culture-positive infections. Multiple risk factors have been reported for ACL reconstruction; however, statistical significance varied across studies. Together, these findings may help guide physicians in the prevention and treatment of infection after ACL reconstruction.

[PMID: 37846316 PMCID: PMC10576935 DOI: 10.1177/23259671231200822] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Accepted: 05/19/2023] [Indexed: 10/18/2023] Open
Abstract
Background Identifying risk factors for an infection after anterior cruciate ligament reconstruction (ACLR) and following targeted preventive strategies can effectively reduce this potentially serious complication. Purpose To perform a systematic review and meta-analysis to identify the risk factors for an infection after ACLR. Study Design Systematic review; Level of evidence, 4. Methods The PubMed, Embase, and Web of Science databases were searched from inception to September 1, 2022, for prospective and retrospective studies investigating risk factors for any type of infection after ACLR. Odds ratios (ORs) or mean differences were calculated for potential risk factors if ≥2 studies assessed the same risk factor. A qualitative analysis of variables was performed if a meta-analysis could not be conducted. Results A total of 17 studies with 141,991 patients were included in this review. The overall pooled infection rate was 0.86% (range, 0.24%-5.50%). There were 20 risk factors identified for analysis. Of these, 7 variables independently increased the odds of an infection after ACLR: (1) male sex (OR, 1.90 [95% CI, 1.33-2.73]), (2) diabetes (OR, 2.69 [95% CI, 1.66-4.35]), (3) hamstring tendon autograft (OR, 2.51 [95% CI, 2.03-3.10]), (4) revision ACLR (OR, 2.31 [95% CI, 1.22-4.37]), (5) professional athlete status (OR, 6.21 [95% CI, 1.03-37.38]), (6) lateral tenodesis (OR, 3.45 [95% CI, 1.63-7.28]), and (7) corticosteroid use (OR, 7.83 [95% CI, 3.68-16.63]). No significant associations were found between postoperative infections and age, body mass index, smoking, meniscal repair, or outpatient surgery. Conclusion This review revealed that an increased risk of infections after ACLR was associated with male sex, diabetes, hamstring tendon autograft, revision surgery, professional athlete status, lateral tenodesis, and steroid use. Knowledge of the risk factors associated with an infection after ACLR may facilitate the identification of high-risk cases and the implementation of preventive measures to mitigate the serious consequences of this complication.

Abstract
PURPOSE Infection after anterior cruciate ligament reconstruction (ACL-R) is a rare but severe complication. Despite an increase in articles published on this topic over the last decade, solid data to optimized diagnostic and therapeutic measures are scarce. For this reason, the European Bone and Joint Infection Society (EBJIS) and the European Society for Sports Traumatology, Knee Surgery and Arthroscopy (ESSKA) collaborated in order to develop recommendations for the diagnosis and management of infections after ACL-R. The aim of the workgroup was to perform a review of the literature and provide practical guidance to healthcare professionals involved in the management of infections after ACL-R. METHODS An international workgroup was recruited to provide recommendations for predefined clinical dilemmas regarding the management of infections after ACL-R. MEDLINE, EMBASE, Cochrane Library and Scopus databases were searched for evidence to support the recommended answers to each dilemma. RESULTS The recommendations were divided into two articles. The first covers etiology, prevention, diagnosis and antimicrobial treatment of septic arthritis following ACL-R and is primarily aimed at infectious disease specialists. This article includes the second part of the recommendations and covers prevention of infections after ACL-R, surgical treatment of septic arthritis following ACL-R and subsequent postoperative rehabilitation. It is aimed not only at orthopedic surgeons, but at all healthcare professionals dealing with patients suffering from infections after ACL-R. CONCLUSION These recommendations guide clinicians in achieving timely and accurate diagnosis as well as providing optimal management, both of which are paramount to prevent loss of function and other devastating sequelae of infection in the knee joint.

Abstract
BACKGROUND The present study aimed to explore the time of maximum bacterial load and main colonization knee site in bacterial infection process based on a novel rat model of septic arthritis (SA) after anterior cruciate ligament reconstruction (ACLR). METHODS Ninety-five Wistar rats with unilateral ACLR, random enrolled into control surgery (CS) group; joint inject (JI) group; presoaking (PS) group, were injected with 30 μl sterile saline or 30 μl × 107 colony forming units/ml Staphylococcus aureus via the knee joint or graft with presoaked Staphylococcus aureus during ACLR, respectively. At 1, 4, 7, 11, and 14 days postoperatively, samples were harvested to evaluate progress of knee joint infection by postoperative body weight, body temperature, knee temperature, knee width, scales of tissue damage, serum inflammatory markers, microbiological counting, microcomputed tomography (Micro-CT), digital radiography, magnetic resonance imaging (MRI) examination, and scanning electron microscopy (SEM). RESULTS No systemic infection was observed in all rats. Comparing with serum inflammatory markers, tissue scores of inflammatory reactions, bacterial counts in the CS group, these data were significantly elevated in the JI group and PS group. The bone mass around the bone tunnel was lower and the soft tissue of knee showed more obvious swelling on MRI in the infection groups than that in the CS group at 7 and 14 days postoperatively. Staphylococcus aureus clusters on the surface of screw and graft were observed in the infection group. The whole colony forming units of Staphylococcus aureus maintained a continuous upward trend peaking 7 and 11 days followed by a balanced curve in the infection groups. Bone and soft tissue were found to have more bacterial counts than graft and screws. CONCLUSION This animal model effectively mimics the acute knee infection after ACLR. We found that the bacterial colonization exhibited the peak of acute infection between 7 and 11 days postoperatively, with the major bacteria loads found in the bone, soft tissue.

Abstract
BACKGROUND Although the infection rates for bone-patellar tendon-bone autograft (BTB), hamstring tendon autograft (HT), and allograft have been reported previously, there are limited data available for a large cohort of individuals undergoing anterior cruciate ligament (ACL) reconstruction (ACLR) using quadriceps tendon autograft (QT). PURPOSE The aims of this study are (1) to compare rates of septic arthritis after primary and revision ACLR with QT, BTB, HT, and allograft and (2) to evaluate the association between an infection after ACLR and potential risk factors in a large single-system analysis. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS All ACLR cases performed by 10 high-volume sports medicine fellowship-trained ACL surgeons between January 2000 and January 2022 were retrospectively analyzed. Minimum follow-up was 90 days after ACLR, and all multiligament reconstructions were excluded. Demographic information, surgical variables, infection characteristics, and rate of ACL graft retention were collected for all included patients. Independent samples t test, chi-square test, or Fisher exact tests with adjusted Benjamini-Hochberg post hoc procedure were used for group comparisons. RESULTS In total, 6652 patients were included in this study. The most commonly used graft was allograft (n = 2491; 37.4%), followed by HT (n = 1743; 26.2%), BTB (n = 1478; 22.2%), and QT (n = 940; 14.1%). The overall postoperative rate of septic arthritis was 0.34% (n = 23). Septic arthritis rates based on graft type were 0.74% (n = 13) for HT, 0.24% (n = 6) for allograft, 0.20% (n = 3) for BTB, and 0.10% (n = 1) for QT. While a statistically significant difference with regard to graft type (P = .01) was observed, no significant relationships were found between postoperative septic arthritis and age, sex, revision ACLR, ACLR surgical technique, and accompanying intra-articular procedures for all septic arthritis patients (P > .05). The average time from the onset of the symptoms of infection to surgical irrigation and debridement (I&D) was 2 days (minimum, 0; maximum, 6). ACL grafts were retained during I&D procedures in all patients with postoperative septic arthritis. CONCLUSION The postoperative rate of septic arthritis was 0.1% after use of the QT autograft. While graft choice may affect rates of septic arthritis after ACLR, patient characteristics, ACLR technique, revision ACLR, and accompanying intra-articular procedures during ACLR were not associated with postoperative septic arthritis with the numbers available for analysis.

Abstract
PURPOSE To compare the effect of vancomycin presoak treatment of grafts during anterior cruciate ligament reconstruction on the incidence of postoperative infection or septic arthritis. METHODS Studies published before May 3, 2022 investigating vancomycin presoak of grafts during anterior cruciate ligament reconstruction were searched in the PubMed and Cochrane Central Register of Controlled Trials. Studies were screened, and data on the incidence of postoperative infection or septic arthritis were extracted and included in the analysis. RESULTS Thirteen studies were included for analysis after search screening, yielding a total of 31,150 participants for analysis, of whom 11,437 received graft vancomycin presoak treatment, and 19,713 did not receive treatment. Participants who received vancomycin treatment had significantly lower infection rates (0.09% versus 0.74%; OR 0.17; 95% CI 0.10, 0.30; P < 0.00001). CONCLUSION Pre-soaking of the graft with vancomycin during ACL reconstruction reduced the incidence of postoperative infection and septic arthritis.

Abstract
OBJECTIVES The primary aim was to evaluate risk factors for surgical site infections after anterior cruciate ligament reconstruction (ACLR). The secondary aim was to investigate the surgical site infection incidence rate and the mean time to postoperative surgical site infection symptoms. DESIGN Systematic review and meta-analysis. DATA SOURCES PubMed, Embase and Web of Science were searched from database inception to September 2021 and updated in April 2022. ELIGIBILITY CRITERIA Quantitative, original studies reporting potential risk factors for surgical site infections after ACLR were included. RESULTS Twenty-three studies with 3871 infection events from 469 441 ACLRs met the inclusion criteria. Male sex (OR 1.78, p< 0.00001), obesity (OR 1.82, p=0.0005), tobacco use (OR 1.37, p=0.01), diabetes mellitus (OR 3.40, p=0.002), steroid use history (OR 4.80, p<0.00001), previous knee surgery history (OR 3.63, p=0.02), professional athlete (OR 4.56, p=0.02), revision surgery (OR 2.05, p=0.04), hamstring autografts (OR 2.83, p<0.00001), concomitant lateral extra-articular tenodesis (OR 3.92, p=0.0001) and a long operating time (weighted mean difference 8.12, p=0.005) were identified as factors that increased the risk of surgical site infections (superficial and deep) after ACLR. Age, outpatient or inpatient surgery, bone-patellar tendon-bone autografts or allografts and a concomitant meniscus suture did not increase the risk of surgical site infections. The incidence of surgical site infections after ACLR was approximately 1% (95% CI 0.7% to 1.2%). The mean time from surgery to the onset of surgical site infection symptoms was approximately 17.1 days (95% CI 13.2 to 21.0 days). CONCLUSION Male sex, obesity, tobacco use, diabetes mellitus, steroid use history, previous knee surgery history, professional athletes, revision surgery, hamstring autografts, concomitant lateral extra-articular tenodesis and a long operation time may increase the risk of surgical site infections after ACLR. Although the risk of surgical site infections after ACLR is low, raising awareness and implementing effective preventions for risk factors are priorities for clinicians to reduce the incidence of surgical site infections due to its seriousness.

Abstract
Deep knee infection (DKI) after anterior cruciate ligament reconstruction (ACLR) is rare and challenging. The optimal treatment strategy for infection after ACLR remains controversial. This study aimed to investigate the optimal treatment for early infection after ACLR surgery. Rats with unilateral ACLR were injected with 3.0 × 105 colony forming units (CFU) of Staphylococcus aureus in the knee joint for 7 days. Next, with surgical debridement (SD) and/or 21 days of antimicrobial (systemic vancomycin and oral rifampicin [SVR]) therapy, rats were euthanatized and samples harvested. We evaluated signs of infection by general postoperative conditions, serum inflammatory markers, microbiological counting, knee radiographs, micro-computed tomography (micro-CT), histologic staining, and scanning electron microscopy (SEM). Clinically, the data from 12 patients who suffered from DKI after ACLR were analyzed retrospectively. The DKI rats treated with SVR showed better outcomes in general postoperative conditions, serum inflammatory markers, microbiological counting, biofilm on the interference screw and graft, radiographic signs of periarticular osseous destruction, and inflammatory reaction in the joint tissues than those with SD treatment, while the DKI rats with SD and SVR administration showed the best outcomes. Rats which received SD and SVR administration had their S. aureus contamination completely eradicated. All patients treated with SD & SVR or SVR alone had effectively controlled knee infections and achieved good knee function outcomes in the 6 months after treatment, but one patient developed more serious knee infections. Therefore, surgical debridement combined with systemic antibiotics treatment could effectively eliminate S. aureus contamination in the DKI rat model and in patients after ACLR without affecting knee function. Treatment with systemic antibiotics could also control early DKI, which would be especially applicable in patients who could not tolerate surgery.

Abstract
BACKGROUND An intra-articular infection after anterior cruciate ligament (ACL) reconstruction (ACLR) is a rare complication but one with potentially devastating consequences. The rare nature of this complication raises difficulties in detecting risk factors associated with it and with worse outcomes after one has occurred. PURPOSE To (1) evaluate the association between an infection after ACLR and potential risk factors in a large single-center cohort of patients who had undergone ACLR and (2) assess the factors associated with ACL graft retention versus removal. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS All ACLR procedures performed at our institution between January 2010 and December 2018 were reviewed; a total of 11,451 procedures were identified. A retrospective medical record review was performed to determine the incidence of infections, patient and procedure characteristics associated with an infection, infection characteristics, incidence of ACL graft retention, and factors associated with the retention versus removal of an ACL graft. Multivariable logistic regression analysis was used to identify potential risk factors for an infection after ACLR. RESULTS Of the 11,451 ACLR procedures, 48 infections were identified (0.42%). Multivariable logistic regression analysis revealed revision ACLR (odds ratio [OR], 3.13 [95% CI, 1.55-6.32]; P = .001) and younger age (OR, 1.06 [95% CI, 1.02-1.10]; P = .001) as risk factors for an infection. Compared with bone-patellar tendon-bone autografts, both hamstring tendon autografts (OR, 4.39 [95% CI, 2.15-8.96]; P < .001) and allografts (OR, 5.27 [95% CI, 1.81-15.35]; P = .002) were independently associated with an increased risk of infections. Overall, 15 ACL grafts were removed (31.3%). No statistically significant differences besides the number of irrigation and debridement procedures were found for retained versus removed grafts, although some trends were identified (P = .054). CONCLUSION In a large single-center cohort of patients who had undergone ACLR and those with an infection after ACLR, patients with revision cases and younger patients were found to have a higher incidence of infection. The use of bone-patellar tendon-bone autografts was found to be associated with the lowest risk of infection after ACLR compared with both hamstring tendon autografts and allografts. Larger cohorts with a larger number of infection cases are needed to determine the factors associated with graft retention versus removal.

Abstract
Postoperative infection remains a potentially devastating complication facing the sports medicine surgeon. Infection prevention begins with a thorough history and physical examination to identify patient specific risk factors and aid in risk stratification. Perioperative steroid injections should be used cautiously, with increased time prior to or following surgery being associated with lower infection risk. Sterile preparation with an alcohol containing solution is typically preferred, though there is limited evidence to identify which product is superior. Diagnosis can be challenging with a high index of suspicion needed to identify and appropriately manage patients. Treatment involves prompt irrigation and debridement with deep cultures. Antibiotic coverage should begin with empiric broad treatment and be tailored based on culture results. Early consultation with an infectious disease specialist is recommended to ensure appropriate antibiotic coverage and duration of treatment.

Abstract
Introduction Postoperative infection is an uncommon complication with grave consequences following anterior cruciate ligament reconstruction (ACLR). Presoaking of the hamstring graft with antibiotics results in a lower rate of infection. The purpose of the current study was to compare the efficacy of two commonly used antibiotics, vancomycin and gentamicin, in reducing infection rates following anterior cruciate ligament reconstruction. Methods The retrospective study included a total of 578 patients who underwent arthroscopic anterior cruciate ligament reconstruction between June 2015 and October 2021. The timeline was categorized as the period between June 2015 to October 2018 (Vancomycin presoaking of hamstring graft) and November 2018 to October 2021 (Gentamicin presoaking of hamstring graft). All patients were examined for the development of infection, causative organism, and treatment received. Patients with intravenous drug abuse, alcoholism, steroid use, revision cases, and a prior history of infection in the knee were excluded from the study. Fisher’s exact test was used for comparison of categorical data, and Poisson regression analysis was carried out to calculate incidence rate ratios after adjusting for confounding variables. Results Presoaking of hamstring grafts with vancomycin was carried out in 224 patients, and gentamicin was used in 354 patients. In total, three patients in the vancomycin and four patients in the gentamicin groups developed an intraarticular infection, and the difference in infection rate between the two groups was not statistically significant (p=0.919). Coagulase-negative Staphylococcus aureus was isolated in four cases, Enterobacter cloacae in one, and no organism was seen in two cases. The groups were comparable in terms of age (p=0.563), smoking (p=0.84), sex (p=0.359), and operative time (p=0.09). Conclusion Presoaking of hamstring autografts with gentamicin intraoperatively is a good alternative to vancomycin in the prevention of infection following arthroscopic anterior cruciate ligament reconstruction.

Abstract
Background: Presoaking anterior cruciate ligament (ACL) grafts in vancomycin has been reported to reduce the occurrence of septic arthritis (SA). However, strong recommendations for its universal use have been precluded by concerns regarding the fragility of previous meta-analyses. Purpose: The primary objective was to investigate whether presoaking ACL grafts in vancomycin was associated with a reduction in the rate of SA in a large series of patients. The secondary objective was to perform an updated systematic review and meta-analysis to determine the efficacy of vancomycin in reducing the rate of SA. Study Design: Cohort study and systematic review; Level of evidence, 3. Methods: A retrospective analysis of patients who underwent primary ACL reconstruction (ACLR) at our institution was undertaken. Rates of postoperative SA were determined and analyzed according to whether patients had received grafts presoaked in vancomycin. A systematic review of the literature and meta-analysis was performed. Odds ratios (ORs) for the risk of SA were calculated according to the inverse variance approach. Results were presented using forest plots, funnel plots, and the fragility index. Results: A total of 5300 patients underwent primary ACLR during the study period. The rate of SA was 0.34% (11/3228) in the control group and 0.05% (1/2072) in the presoaked group. There was a 5-fold greater risk of SA in patients who did not receive grafts presoaked in vancomycin (OR, 5.13 [95% CI, 1.16-48.30]; P = .04). Overall, 11 studies were included in the systematic review (29,659 ACLR procedures). The meta-analysis demonstrated a significantly greater risk of SA in those patients who did not receive grafts presoaked in vancomycin (OR, 14.39 [95% CI, 5.90-35.10]; fragility index = 23). This finding held true for the subpopulation receiving hamstring tendon grafts (fragility index = 16), but only a trend was demonstrated for bone–patellar tendon–bone grafts. Conclusion: The meta-analysis demonstrated that presoaking ACL grafts in vancomycin was associated with significant reductions in the rates of SA when all graft types were analyzed together. This finding held true specifically for hamstring tendon autografts. The fragility index of these findings allows for a strong recommendation for the universal use of vancomycin presoaking. However, it should be noted that only a trend toward reduced SA rates was demonstrated with presoaking bone–patellar tendon–bone autografts in vancomycin.

Intraoperative and Early (90-Day) Postoperative Complications and Associated Variables with Multiligamentous Knee Reconstruction: 15-year Experience from a Single Academic Institution. Arthroscopy 2022; 38:427-438.

Abstract
PURPOSE We sought to determine the rate of intraoperative and early postoperative (90-day) complications of multiligamentous knee reconstruction surgeries, both medical and surgical, and associated variables from the 15-year experience of a single academic institution. METHODS Patients treated at a single academic institution between 2005 and 2019 who underwent multiligament knee surgery were identified. Inclusion criteria included intervention with 2+ ligament reconstructions performed concurrently, and more than 90 days postoperative follow-up. Exclusion criteria included revision ligamentous knee surgery. Patient demographics, mechanism of injury, and associated injuries of patients with intraoperative and postoperative complications, time from injury to multiligamentous knee reconstruction, and surgical data, including tourniquet time, procedure time, and type of procedures performed were retrospectively recorded. RESULTS 301 knees in 296 patients met the eligibility criteria. There were 11 intraoperative complications in 9 knees (rate of 3%) and 136 postoperative complications in 90 knees (rate of 30%). Shorter time from injury to date of surgery was associated with arthrofibrosis (P = .001) and superficial wound infections (P = .015). Concurrent head injuries were associated with less complications (P = .029). Procedural time >300 minutes was associated with intraoperative blood transfusions (P > .05), deep infections (P = .003) and arthrofibrosis (P = .012). Inside-out meniscal repair was associated with superficial and deep infections (P = .006 and .0004). Tibial-based posterolateral corner (PLC) reconstruction was associated with symptomatic hardware (P = .037) and arthrofibrosis (P = .019) in comparison with fibular-based PLC reconstruction. Posterior cruciate ligament (PCL) reconstruction was associated with deep infections (P = .015), arthrofibrosis (P = .003), and postoperative blood transfusions (P = .018). CONCLUSION Our 15-year data reveal there is a low intraoperative complication rate and high early postoperative complication rate with multiligamentous knee surgery. Surgeons should be wary of the increased intraoperative and postoperative complications associated with longer procedure times, inside-out meniscal repair, tibia-based PLC reconstruction, PCL reconstruction, and shorter time to surgery. LEVEL OF EVIDENCE Case series: IV.

Abstract
Due to its low invasive nature, arthroscopy nowadays represents the gold standard in the treatment of native joint empyema. This article gives a summary of the literature with expert recommendations, reviews and case reports on arthroscopic treatment of native joint empyema and the limitations. Most cases of native joint empyema can be successfully cleansed with arthroscopic treatment alone including lavage and débridement. In advanced stages of infection open arthrotomy is often needed for final infection cleansing. In postoperative infections with enclosed foreign material, such as after cruciate ligament reconstruction, the foreign material can in most cases be left in and successful infection eradication can be carried out with several arthroscopic lavages and débridement. In cases of higher grade infections with destruction of the joint, arthroscopic treatment alone is normally insufficient.

Abstract
OBJECTIVE To summarize the experience in the diagnosis and management of septic arthritis after anterior cruciate ligament reconstruction. METHODS A retrospective review was conducted of all the arthroscopic anterior cruciate ligament reconstructions performed at Department of Sports Medicine, Peking University Third Hospital between January 2001 and December 2020. In the study, 65 of 27 867 patients experienced postoperative septic arthritis. The incidence, presentation, laboratory results, treatment, and outcome of all the infected patients were analyzed. The experiences of diagnosis and management of septic arthritis after anterior cruciate ligament reconstruction were summarized. RESULTS A total of 27 867 anterior cruciate ligament reconstructions were performed at our department between January 2001 and December 2020. In the study, 65 (0.23%) patients were identified with postoperative septic arthritis. The most common symptoms of the infected patients were fever (38.7±0.5) ℃, knee swelling, pain, and restricted motion. The mean peripheral white blood cell count (WBC) was (9.2±2.6)×109/L (range 4.2×109/L-19.4×109/L), with (72.5±6.3) % (range 54.9%-85.1%) polymorphonuclear neutrophils (N). The mean erythrocyte sedimentation rate (ESR) was (59.9±24.1) mm/h (range 9-108 mm/h), C-reactive protein (CRP) was (10.9±5.7) mg/dL (range 1.2-30.8 mg/dL), and fibrinogen (FIB) level was (7.0±1.6) g/L (range 3.7-10.8 g/L). All of the laboratory results were statistically higher in the infection group compared with the normal postoperative group (P<0.001). The synovial white blood cell count (SWBC) of aspirated knee joint fluid was (45.0±29.8)×109/L (range 7.1×109-76.5×109/L). Polymorphonuclear cell percentage (PMNC) was (90.27±7.86) % (range 60%-97%). In the study, 45 patients (69.2%) had positive aspirate cultures. Microbiology showed coagulase-negative Staphylococcus (CNS) and Staphylococcus aureus (SA) were the most common bacterium (34 cases and 7 cases, individually). There were 26 methicillin-resistant Staphylococcus. Both conservative (16 patients) and operative (49 patients) treatments were effective, but conservative group had a longer recovery time (5.6 d vs. 1.6 d, P=0.042). CONCLUSION Septic arthritis after arthroscopic anterior cruciate ligament reconstruction is a rare but potentially devastating complication. The correct diagnosis relies on synovial fluid analysis and bacterial culture. Our proposed treatment protocol is arthroscopic debridement and antibiotic therapy as quickly as possible.

Abstract
Knee septic arthritis is a devastating complication following anterior cruciate ligament (ACL) reconstruction. To prevent this issue, intraoperative soaking of ACL grafts with vancomycin is often performed before implantation. Although vancomycin cytotoxicity has been reported several times, little is known about its biological effect on tenocytes. The aim of this study was to evaluate the in vitro effects of vancomycin on human primary tenocytes (hTCs). hTCs were isolated from hamstring grafts of four patients undergoing ACL reconstruction. After expansion, hTCs were treated with different concentrations of vancomycin (0, 2.5, 5, 10, 25, 50 and 100 mg/mL) for 10, 15, 30 and 60 min. In vitro cytotoxicity was evaluated measuring metabolic activity, cell toxicity, and apoptosis. hTC metabolic activity was affected starting from 10 mg/mL vancomycin and decreased markedly at 100 mg/mL. Cell viability remained unaffected only at a concentration of 2.5 mg/mL vancomycin. Vancomycin cytotoxicity was detected from 10 mg/mL after 15 min and at all higher concentrations. Cells died when treated with concentrations higher than 5 mg/mL. The use of this antibiotic on tendons to prevent infections could be useful and safe for resident cells if used at a concentration of 2.5 mg/mL for up to 1 h of treatment.

Abstract
BACKGROUND Arthroscopic single-bundle surgical reconstruction of the anterior cruciate ligament (ACL) is often performed electively after 3 weeks of mobilization therapy. The present single-center retrospective study aimed to investigate the effects of temperature and volume of intraoperative normal saline irrigation on postoperative pain and swelling and on serum markers of inflammation following elective, arthroscopic, single-bundle surgical reconstruction of the ACL. MATERIAL AND METHODS Clinical data from 716 patients with non-acute ACL injuries who met the criteria between March 2015 and May 2020 were retrospectively analyzed. The patients were broken into 5 groups, depending on the volume or temperature of intraoperative irrigation with normal saline. At specific times after surgery, pain, knee swelling, and skin temperature were assessed. Postoperative levels of serum C-reactive protein (CRP), interleukin (IL)-1, IL-6, and IL-10 also were measured. RESULTS Visual analog scale (VAS) scores for pain, rates of swelling, and skin temperature differed significantly among the 5 groups at all postoperative time points (P<0.001). The VAS scores(P=0.322) and ratings for swelling (P=0.245), and skin temperature (P=0.093) were not significantly different among the volume groups. There were no significant differences in the VAS scores (P=0.055), swelling ratings (P=0.570), or skin temperatures (P=0.321) among the groups that received irrigation with normal saline at different temperatures. There were no significant differences in postoperative serum levels of CRP, IL-1, IL-6, or IL-10 among the groups (P>0.05). CONCLUSIONS Irrigation with different volumes and temperatures of normal saline did not have a significant effect on postoperative pain, swelling, or serum markers of inflammation.

Abstract
PURPOSE Septic arthritis is a significant complication following arthroscopic surgery, with an estimated overall incidence of less than 1%. Despite the low incidence, an appropriate diagnostic and therapeutic pathway is required to avoid serious long-term consequences, eradicate the infection, and ensure good treatment outcomes. The aim of this current review article is to summarize evidence-based literature regarding diagnostic and therapeutic options of post-operative septic arthritis after arthroscopy. METHODS Through a literature review, up-to-date treatment algorithms and therapies have been identified. Additionally, a supportive new algorithm is proposed for diagnosis and treatment of suspected septic arthritis following arthroscopic intervention. RESULTS A major challenge in diagnostics is the differentiation of the post-operative status between a non-infected hyperinflammatory joint versus septic arthritis, due to clinical symptoms, (e.g., rubor, calor, or tumor) can appear identical. Therefore, joint puncture for microbiological evaluation, especially for fast leukocyte cell-count diagnostics, is advocated. A cell count of more than 20.000 leukocyte/µl with more than 70% of polymorphonuclear cells is the generally accepted threshold for septic arthritis. CONCLUSION The therapy is based on arthroscopic or open surgical debridement for synovectomy and irrigation of the joint, in combination with an adequate antibiotic therapy for 6-12 weeks. Removal of indwelling hardware, such as interference screws for ACL repair or anchors for rotator cuff repair, is recommended in chronic cases. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE To determine and compare the incidence of post-operative septic arthritis following revision anterior cruciate ligament reconstruction (R-ACLR) with autologous quadriceps tendon (with patellar bone block) compared to autologous hamstring tendons (semitendinosus and gracilis). METHODS A total of 1638 isolated R-ACLR with either autologous hamstring tendons (n = 1004, 61.3%) or quadriceps tendon (n = 634; 38.7%) were performed between 2004 and 2017 and were retrospectively analysed with regard to the occurrence of post-operative septic arthritis. The technique of R-ACLR did not significantly change during the years of the study. All patients received pre-op i.v.antibiotics, but no presoaking of the grafts in vancomycin was performed in the years of the study. The individual decision of graft choice was based on graft availability, tunnel position and the presence of tunnel widening. Generally, hamstring tendons were preferred. There were no clinically relevant differences between the groups regarding gender or age. Routine follow-up examination was performed 6 weeks after the index operation (follow-up rate 96.5%), and patients unsuspicious for septic arthritis at that time were classified as non-infected. RESULTS Fourteen patients with septic arthritis were identified, resulting in an overall incidence of 0.85%. There was one patient with septic arthritis in the quadriceps tendon group (incidence: 0.16%) and 13 patients in the hamstring tendons group (incidence: 1.29%), respectively. The difference was significant (p = 0.013). CONCLUSION In this series, the incidence of post-operative septic arthritis after R-ACLR was lower when quadriceps tendon graft was used compared to hamstring tendon grafts. LEVEL OF EVIDENCE III.

Abstract
PURPOSE To determine and compare the incidence of postoperative septic arthritis following anterior cruciate ligament reconstruction (ACLR) with and without soaking of the graft in vancomycin solution prior to implantation in a large single-centre case series. METHODS From 2004 to 2019, a total of 10,516 primary ACLR were performed and reviewed with regard to the occurrence of postoperative septic arthritis. From February 2017 onwards, all grafts were wrapped in a vancomycin-soaked (5 mg/ml) gauze swab between harvest and implantation (2294 patients, treatment group (2), prospectively followed). These were compared to 8222 patients before that date (control group (1), retrospectively evaluated). The technique of ACLR did not significantly change during the years of the study. There was no difference between the groups with regard to graft choice: Hamstring tendons were used in 99% and quadriceps tendons were used in 1% in both groups, respectively (n.s.). Routine follow-up examination was performed at 6 weeks (follow-up rate 97.1%) postoperatively. Patients with no treatment for septic arthritis at that time were classified as non-infected. RESULTS There were 35 cases of postoperative septic arthritis in group 1 (incidence: 0.4%), and none in group 2 (incidence 0.0%), respectively. The difference was significant (p < 0.001). CONCLUSIONS Soaking of the graft in vancomycin solution prior to implantation dramatically reduces the incidence of postoperative septic arthritis in primary ACLR and should, therefore, be used in prevention of this major complication.

Abstract
A stringent outcome assessment is a key aspect of establishing evidence-based
clinical guidelines for anterior cruciate ligament (ACL) injury treatment. To
establish a standardized assessment of clinical outcome after ACL treatment, a
consensus meeting including a multidisciplinary group of ACL experts was held at
the ACL Consensus Meeting Panther Symposium, Pittsburgh, Pennsylvania, USA, in
June 2019. The aim was to establish a consensus on what data should be reported
when conducting an ACL outcome study, what specific outcome measurements should
be used, and at what follow-up time those outcomes should be assessed. The group
reached consensus on 9 statements by using a modified Delphi method. In general,
outcomes after ACL treatment can be divided into 4 robust categories: early
adverse events, patient-reported outcomes (PROs), ACL graft failure/recurrent
ligament disruption, and clinical measures of knee function and structure. A
comprehensive assessment after ACL treatment should aim to provide a complete
overview of the treatment result, optimally including the various aspects of
outcome categories. For most research questions, a minimum follow-up of 2 years
with an optimal follow-up rate of 80% is necessary to achieve a comprehensive
assessment. This should include clinical examination, any sustained reinjuries,
validated knee-specific PROs, and health-related quality of life questionnaires.
In the midterm to long-term follow-up, the presence of osteoarthritis should be
evaluated. This consensus paper provides practical guidelines for how the
aforementioned entities of outcomes should be reported and suggests the
preferred tools for a reliable and valid assessment of outcome after ACL
treatment.

Abstract
BACKGROUND Arthroscopic debridement with graft preservation has been advocated as the treatment of choice for septic arthritis after anterior cruciate ligament (ACL) reconstruction, but no previous studies have investigated if hardware removal, while retaining the graft in situ, improves the success rate. Moreover, it is unclear whether the premature removal of fixation devices may affect graft integration and knee stability. PURPOSE/HYPOTHESIS The purpose was to assess the clinical and functional outcomes of patients with septic arthritis after ACL reconstruction who underwent arthroscopic debridement, while retaining the graft in situ but removing fixation devices, and to determine if premature hardware removal affects graft integrity and function. The hypothesis was that arthroscopic debridement with hardware removal would be effective in eradicating infections while not compromising graft integration and function. STUDY DESIGN Case series; Level of evidence, 4. METHODS From a cohort of 2384 cases of arthroscopic ACL reconstruction, 24 patients with postoperative septic arthritis were included for the analysis; 18 patients were available for a clinical evaluation using the International Knee Documentation Committee (IKDC) form, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Lysholm score, and Tegner score at a minimum 12-month follow-up. Knee laxity was assessed clinically with standardized manual laxity tests and instrumentally using an arthrometer and a triaxial accelerometer. Additionally, 3-T magnetic resonance imaging (MRI) at final follow-up was performed, focusing on the graft signal, the cartilage status, and the occurrence of arthrofibrosis. RESULTS Eradication of the infection was achieved in all cases, and only 1 graft removal was performed because of insufficient tension. Among the remaining 23 patients, a single arthroscopic debridement procedure with hardware removal while preserving the graft was effective in 21 cases (91%) at a mean of 30 ± 37 days from ACL reconstruction to debridement. At last follow-up, 2 patients required a further ACL revision procedure. The mean IKDC, WOMAC, Lysholm, and Tegner scores of the patients available for the clinical evaluation were 75 ± 19, 90 ± 8, 79 ± 21, and 6 ± 2, respectively. No abnormal laxity was reported on manual testing, and arthrometric and accelerometer tests also demonstrated good knee stability (mean KT-1000 arthrometer side-to-side difference was 1.6 ± 1.2 mm at manual maximum force). On MRI, a good graft signal was found in 50% of cases, while concomitant signs of arthrofibrosis were detected in 81% of patients. Severe cartilage defects (International Cartilage Repair Society grade ≥3) were reported in 63% of cases. CONCLUSION Arthroscopic debridement with hardware removal was effective in the eradication of infections after ACL reconstruction with extra-articular fixation while preserving graft integrity without compromising knee stability. Patients and surgeons should be aware of complications that might affect the outcome, particularly arthrofibrosis and chondrolysis.

Abstract
Background Arthroscopic partial meniscectomy is a common procedure in orthopedic practice. Infections are uncommon complications of this procedure with an incidence rate of 0,01% - 3,4%. Staphylococcus spp are the predominant causative agents in such cases. We present a case of knee septic arthritis caused by α-hemolytic Streptococcus. Case presentation A 22-year-old woman diagnosed with obesity (body mass index [BMI] 35 kg/m2) but with no other major comorbidities underwent an arthroscopic selective meniscectomy with administration of intravenous cefazolin for antibiotic prophylaxis. After an uneventful period of 2 months, the patient returned with pain, fever and a discharging sinus at the site of anterolateral arthroscopic portal. Blood tests and magnetic resonance imaging revealed osteomyelitis involving the tibial plate. Cultures of synovial fluid obtained from the knee and a pharyngeal swab yielded α-hemolytic Streptococcus. Five days later, the patient underwent arthroscopic debridement with partial synovectomy. Intraoperative specimens yielded α-hemolytic Streptococcus. The patient received intravenous piperacillin/tazobactam, followed by an associative regimen of amoxicillin and clindamycin with clinical, laboratory and instrumental evidence of symptom resolution. Conclusion The incidence of knee septic arthritis after arthroscopic partial meniscectomy is 0.01–3.4%. This infection is usually caused by Staphylococcus spp. and in rare cases by commensal bacteria, such as α-hemolytic streptococci, secondary to transient bacteremia. Screening of the colonized area is important to prevent possible transient bacteremia. Diagnosis is based on isolation of the causative organisms from synovial fluid cultures, and treatment comprises arthroscopic debridement with individualized systemic antibiotic therapy based on the results of an antibiogram.

Abstract
Background: The rates of return to full activity, persistent disability, complications, and surgical revisions after operative management of posterior cruciate ligament (PCL) tears in a physically active population have not been reported. Purpose: To evaluate the clinical outcomes of active military patients with symptomatic PCL tears who underwent surgical reconstruction and compare outcomes between isolated PCL and multiligament injuries. Study Design: Cohort study; Level of evidence, 3. Methods: Individuals undergoing surgical reconstruction of the PCL (Current Procedural Terminology code 29889) were isolated from the Military Health System Management Analysis and Reporting Tool between fiscal years 2005 and 2010. Demographic variables and rates of postoperative complications, activity limitations, rates of revision surgery, physical disability ratings, and ultimate medical discharge were recorded from the electronic medical record and US Army Physical Disability Agency database. Results: A total of 182 patients underwent 193 surgeries, including 118 isolated PCL reconstructions and 75 multiligament knee reconstructions, with an average follow-up of 19.5 months. There were 174 primary procedures and 19 revision reconstructions. The mean ± SD patient age was 28.4 ± 7.2 years, with males comprising 96.2% of patients. The overall surgical complication rate was 12.4%, with a significantly higher rate in multiligament knee reconstructions compared with isolated PCL reconstructions (18.7% vs 8.5%; P = .045). Overall, 35.1% of patients were discharged from military service due to disability. Rates of discharge were significantly higher in those undergoing surgery at lower volume institutions (those that performed <2 PCL reconstructions per year during the study period) than those at higher volume institutions (41.1% vs 26%; P = .040). The overall revision rate was 10.9%, with no significant difference between the isolated PCL and multiligament knee reconstructions. Of the 103 patients with primary isolated PCL reconstructions, 35% underwent medical discharge for persistent knee complaints, and 12.6% required revision PCL reconstruction. The overall failure rate for primary isolated PCL reconstructions, which includes both revision surgery and knee-related medical discharge from military service, was 42.7%. Conclusion: In a physically active, military population, nearly one-third of patients were unable to return to previous level of military function, and 12.6% required revision at short-term follow-up due to persistent instability. Perioperative complication rates were significantly higher among patients with multiligament knee reconstructions.

Abstract
Objective To evaluate the contamination rate of hamstring tendon autografts by comparing two different techniques, and to verify whether intraoperative contamination is associated with the development of clinical infection in patients submitted to reconstruction of the anterior cruciate ligament (ACL). Methods A total of 110 hamstring tendon autograft ACL reconstructions were performed and divided into two groups: 1–hamstring tendon retraction technique; and 2 - technique maintaining the tibial insertion of the hamstring tendon. During the preparation, two graft fragments were sent for culturing; the harvesting time, the preparation time, and the total surgery time were measured. Twenty-four hours after the surgery, the C-reactive protein was assayed. The clinical outpatient follow-up was performed up to 180 days postoperatively. Results
Although there were two postoperative infections, there was no graft contamination or difference between the groups in relation to the graft preparation time and to the 24-hour postoperative C-reactive protein assessment. The classic technique presented a longer graft harvesting time (
p
= 0.038), and there was no statistical difference between the 2 groups regarding the degree of contamination and consequent clinical infection, although 2 patients in group 2 presented with infection, with negative perioperative cultures.
Conclusion Based on the results obtained, there was no association between graft contamination and the time or technique of its preparation. In addition, there was also no association between intraoperative contamination and the development of clinical infection, nor was there any sign of an association between the early alteration of C-reactive protein and the onset of infection.

Abstract
The practice of 'vancomycin wrapping' of harvested hamstring autografts during Anterior Cruciate Ligament Reconstruction (ACLR) surgery has gathered recent interest. This practice involves the wrapping of harvested grafts in a vancomycin-soaked swab during the preparatory phase. Different techniques are observed, and a small number of studies have shown that pre-soaking hamstring ACLR grafts in this manner dramatically reduces the post-surgical infection rate compared with standard intravenous antibiotic prophylaxis alone. However, the literature surrounding this practice is surprisingly limited and thus the basis and rationale of the 'vancomycin wrap' has established itself largely without question. The exact popularity of this practice is difficult to establish but there has been increasing disclosure of its efficacy in reducing post-operative infection in ACLR since 2012. We provide a synopsis of the current literature surrounding vancomycin and its use in 'wraps' in ACLR to help apprise the surgeon of the nature of infection in ACLR, the rationale for vancomycin, whilst considering evidence to support alternatives and discussing potential ramifications for future practice.

Septic arthritis after arthroscopic posterior cruciate ligament and multi-ligament reconstructions is rare and can be successfully treated with arthroscopic irrigation and debridement: analysis of 866 reconstructions. Knee Surg Sports Traumatol Arthrosc 2018; 26:3029-3038.

Abstract
PURPOSE The purpose of this study was to determine the incidence of septic arthritis following arthroscopic posterior cruciate ligament (PCL) and multi-ligament reconstructions, and to evaluate a treatment regime with sequential arthroscopic irrigation and debridement procedures combined with antibiotic therapy that is focused on retention of the graft. METHODS Between 2004 and 2016 a total of 866 PCL reconstructions and multi-ligament reconstructions were performed at our institution (408 isolated PCL reconstructions, 458 combined reconstructions). Medical charts of all cases were retrospectively reviewed with regard to the occurrence of septic complications. These cases were analysed with special focus on clinical management, number of reoperations and if the grafts were retained. Further, microbiological findings, postoperative clinical course and available clinical outcome data were evaluated. RESULTS Four cases of septic arthritis (0.5%) were identified (follow-up rate 96.5%): two following isolated PCL reconstruction (0.5%), and two following multi-ligament reconstruction (0.4%), respectively. Septic arthritis was successfully treated in all cases with a mean of 2.5 ± 2.4 irrigation and debridement procedures (1-6). In one case of isolated PCL reconstruction, the graft was resected within the fifth irrigation and debridement due to septic loosing of the femoral fixation. All other grafts were retained. With regard to the outcome, all patients were subjectively satisfied with good stability (stress radiographs) in cases of retained grafts. CONCLUSION Postoperative septic arthritis after arthroscopic PCL and complex knee ligament reconstructions is a rare but serious complication. Arthroscopic graft-retaining treatment is recommended, as it is established in ACL surgery. Graft retention can be expected in the majority of the cases. LEVEL OF EVIDENCE Case series, Level 4.

Abstract
BACKGROUND Septic arthritis (SA) of the knee after anterior cruciate ligament reconstruction (ACLR) is a rare but potentially devastating condition. In certain cases, graft removal becomes necessary. PURPOSE To evaluate clinical, subjective, and radiologic outcomes of patients with SA after ACLR and assess whether graft retention has superior clinical results as compared with graft removal. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS All patients who were at least 12 months out from arthroscopic treatment of SA after isolated ACLR at our institution were eligible for inclusion. Patients were categorized into 2 groups: group 1, patients with initial graft retention; group 2, patients with initial graft removal. Group 2 was subdivided into 2 groups: group 2a, patients with graft reimplantation; group 2b, patients without graft reimplantation. Objective and subjective assessments were obtained at follow-up, including the International Knee Documentation Committee (IKDC) knee examination form, KT-1000 arthrometer measurements, WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) score, Lysholm score, and IKDC subjective evaluation. Radiologic assessment was performed with pre- and postoperative magnetic resonance imaging. RESULTS Of the 41 patients included, 33 (81%) were available for follow-up at a mean ± SD 54.7 ± 24.4 months at an age of 28.4 ± 9.3 years. When compared with patients from group 2 (n = 12), patients from group 1 (n = 21) obtained significantly better results on the objective IKDC score (normal or nearly normal: group 1, 66.6%; group 2, 36.4%; P = .047) and KT-1000 measurements (group 1, 1.3 ± 1.0 mm; group 2, 2.9 ± 1.5 mm; P = .005). Group 1 also scored better than group 2 on the Lysholm ( P = .007), IKDC subjective ( P = .011), and WOMAC ( P = .069) measures. Between groups 2a (n = 4) and 2b (n = 8), no significant differences in outcomes could be detected ( P values, .307-.705), although patients with anterior cruciate ligament graft reimplantation showed a clear tendency toward better results in objective and not subjective parameters. Magnetic resonance imaging evaluation showed higher rates of cartilage damage and meniscal tears among patients with graft resection versus graft retention. CONCLUSION Patients with graft retention showed superior postoperative results when compared with patients who underwent initial graft resection, although subanalysis showed comparable outcomes between graft retention and reimplantation. Thus, while graft-retaining protocols should have the highest priority in the treatment of SA after ACLR, graft reimplantation should be performed in cases where graft resection becomes necessary, to avoid future cartilage and meniscal lesions. Finally, further studies with larger numbers of patients are needed to gain a better understanding of the outcomes of patients with SA after ACLR.

Meniscus repairs can be saved in the event of postoperative septic arthritis. Knee Surg Sports Traumatol Arthrosc 2018; 26:2289-2296.

Abstract
PURPOSE No systematic studies on optimal treatment of postoperative septic arthritis following arthroscopic meniscus repair are available. The purpose of this study was to retrospectively evaluate the fate of repaired menisci in cases of postoperative septic arthritis, with treatment for infection focused on arthroscopic irrigation and debridement (I&D) and intention to maintain the meniscus. METHODS Data of two sports orthopedics centers of the last 10 years were pooled (approximately 25,000 arthroscopic procedures of the knee). All cases of septic arthritis following arthroscopic meniscus repair were identified. These cases were retrospectively evaluated with regard to clinical course and management, especially the number of necessary I&Ds, if eradication was achieved, and if the repaired meniscus was retained or a partial resection was necessary ('early failure'). Patients with initially maintained meniscus repairs were contacted if further meniscus surgery was performed in further follow-up ('late failure'). RESULTS 20 patients with 23 repaired menisci were included. In 65% (13 cases), a concomitant anterior cruciate ligament reconstruction was performed. A mean of 2.0 ± 1.0 (1-4) arthroscopic I&Ds were performed in the treatment of septic arthritis. In two cases, additional open surgery was performed (after outside-in sutures). Eradication was achieved in all cases. Four repaired menisci (17.4%) showed loosened fixation or substantial degradation and were consequently partially resected within treatment for septic arthritis (early failures). The follow-up rate for the 19 initially maintained menisci was 94.7% after 3.0 ± 2.2 years (median 2.8, 0.4-7.8). Three of these underwent further partial resection (13.0%). Cumulative 3-year survival rate (Kaplan-Meier method) of all repairs was 70.7% (95% CI 50.3-91.1%), and for the subgroup of initially maintained menisci 85.6% (95% CI 67.0-100.0%), respectively. CONCLUSION Septic arthritis following meniscus repair can be successfully treated with (sequential) arthroscopic I&Ds. There is a considerable rate of early failures, however, in a mid-term follow-up the failure rate of initially retained menisci is low and comparable to what we know from the literature for cases without infection. Therefore, it is generally recommended to try to save the repaired menisci in these cases. LEVEL OF EVIDENCE IV, therapeutic case series.

Abstract
Background: There remains a debate over whether to retain the index anterior cruciate ligament (ACL) graft in the setting of septic arthritis. Purpose: To evaluate and compare clinical outcomes for the treatment of septic arthritis after ACL reconstruction (ACLR) in those with and without early graft retention. Study Design: Case series; Level of evidence, 4. Methods: The Military Health System was queried for all ACLR procedures performed between 2007 and 2013. Inclusion criteria required active military status, primary ACLR with secondary septic arthritis, and minimum 24-month surveillance. Demographic, clinical, and surgical variables were evaluated using descriptive statistics and regression analysis for factors influencing selected outcomes. Results: Of 9511 ACLR procedures, 31 (0.32%) were identified as having secondary septic arthritis requiring urgent arthroscopic irrigation and debridement and intravenous antibiotics (mean, 6.3 weeks). The majority (62%) were treated in the subacute (2 weeks to 2 months) setting. Index ACLR was performed with a hamstring autograft (n = 17, 55%), soft tissue allograft (n = 11, 35%), and patellar tendon autograft (n = 3, 10%). The graft was retained in 71% (n = 22) of patients, while 29% (n = 9) underwent early graft debridement. At a mean 26.9-month follow-up, 48% of patients (n = 15) had returned to the military. Graft removal was not predictive of return to active duty (P = .29). The presence of postoperative complications, including symptomatic postinfection arthritis (22.6%) and arthrofibrosis (9.7%), was the only variable predictive of inability to return to duty (odds ratio, 27.5 [95% CI, 3.24-233.47]; P = .002). Seven of 9 patients who underwent graft debridement underwent revision ACLR, and all 7 had stable knees at final follow-up compared with 68% (15/22) in the graft retention group. Conclusion: Arthroscopic debridement with early graft removal and staged revision ACLR remains a viable option for restoring knee stability (100%), although the rate of return to active duty was low in the graft resection group (33%). The risk of knee laxity did not differ based on early graft retention. Time to presentation with graft retention was not associated with a decreased rate of graft laxity.

Abstract
PURPOSE Why anterior cruciate ligament (ACL) autograft soaking in a 5 mg/ml vancomycin solution decreases the rate of infection has not been well-explained. One hypothesis is that grafts can be contaminated during harvesting and vancomycin eradicates the bacteria. The purpose of the present study is to assess how the vancomycin solution acts against ACL graft contamination during graft harvesting and preparation. METHODS The study was carried out in three university hospitals over a period of 6 months. After sample size calculation, 50 patients were included in the study. Three samples were taken from each ACL graft. Sample 1 was obtained immediately after graft harvesting. After graft manipulation and preparation, the remaining tissue was divided into two parts. The raw sample was denominated sample 2 and sample 3 consisted of the rest of the remaining tissue that had been soaked in the vancomycin solution. All the cultures were incubated at 37 °C with 5% CO2 in agar plates for 7 days (aerobically) or 14 days (anaerobically) and inspected daily for microbial growth. Any bacterial growth and the number of colony forming units were reported. RESULTS In seven cases (14%), either sample 1 or sample 2 was positive. In five of the cases (10%), only the sample after graft preparation was positive (sample 2). In two cases (4%), sample 1 and sample 2 were positive for the same bacteria. Isolated microorganisms corresponded to coagulase-negative staphylococci (CNS) and Propionibacterium acnes. No bacterial growth was observed in sample 3 (p < 0.001). Thus, none of those seven positive cases (0%) were positive after vancomycin soaking (p < 0.001). CONCLUSION In the series, ACL graft harvesting and manipulation leads to bacterial contamination in 14% of the cases. This contamination is fully eradicated after soaking in the vancomycin solution in this series. LEVEL OF EVIDENCE Level II.

Abstract
BACKGROUND Infection after anterior cruciate ligament reconstruction surgery (ACLRS) is a rare complication. Although there are number of studies from various Caucasian population but only few studies are available from Asian population. The aim of the study is to assess the incidence, risk factors and, clinical outcome using our treatment protocol. MATERIALS AND METHODS Out of 1468 arthroscopic ACLRS, 26 patients with clinical suspicion of infection were critically analysed in terms of laboratory reports of arthrocentesis, erythrocyte sedimentation rate, C-reactive protein and risk factors such as the type of graft, gender, diabetes mellitus, smoking, intraarticular steroid injection, and obesity. At final followup, all these patients were evaluated using visual analog scale (VAS), Lysholm knee score, and Tegner activity level. RESULTS In nine patients, culture did not show any growth and they showed improvement with arthrocentesis and oral antibiotics. These patients were labeled as suffering from aseptic effusion. In the remaining 17 patients, there was no clinical improvement or instead worsening of symptoms after arthrocentesis and oral antibiotics. These patients were labeled as suffering from an infection and underwent surgical debridement along with administration of injectable antibiotics. The history of intraarticular steroid injection before ACLRS was a significant risk factor for developing infection (P = 0.001). At mean followup of 2.8 years, mean VAS improved to 1.18 ± 0.99 from 6.2 ± 2.3. The mean Lysholm knee score and Tegner's activity level at the final followup were 79.2 ± 10.52 and 4.8 ± 2.30, respectively. CONCLUSION The incidence of infection was 1.2% (17/1468). The step-ladder approach of differentiating between aseptic effusion and infection and accordingly, following a treatment protocol, i.e., oral antibiotics alone or surgical debridement along with injectable antibiotics or additional debridement of graft in refractory patients, yielded satisfactory results.

Abstract
We present the case of an adolescent male developing an ankylosis of the knee after septic arthritis following anterior cruciate ligament reconstruction (ACLR). The patient was shifted to our institution with postoperative septic arthritis associated with a systemic septic condition. Before, repeated arthroscopic surgery had been conducted without any improvement. MRI showed a concomitant osteomyelitis. The infection (Gächter IV, Staphylococcus aureus) was controlled by an open surgical approach and graft removal. An increasing joint stiffness was documented. X-rays showed an ankylosis at 30° of flexion and early closure of growth plates. Functional knee scores showed significantly worse results. Early diagnosis and a stage-adapted treatment in septic arthritis following ACLR are mandatory. In advanced stages or concomitant osteomyelitis an open approach and graft removal may be appropriate. The antibiotic treatment should be adapted consistently.
