Korytárová N, Kramer S, Harms O, Volk HA. Clinical relevance of positive intraoperative bacterial culture in tibial plateau leveling osteotomy in dogs: a retrospective study. BMC Vet Res 2024; 20:175. [PMID: 38704532 PMCID: PMC11069177 DOI: 10.1186/s12917-024-04007-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2024] [Accepted: 04/04/2024] [Indexed: 05/06/2024] Open
Abstract
BACKGROUND Tibial plateau leveling osteotomy (TPLO) belongs to the most frequently used surgical method for the treatment of cranial cruciate ligament rupture in dogs. Surgical site infection (SSI) is one of the possible postoperative complications. The aim of this study was to evaluate the diagnostic value of intraoperative bacterial culture as a tool for the detection of intraoperative bacterial contamination progressing to infection development in canine TPLO. Electronic patient records from dogs who underwent TPLO between January 2018 to December 2020 were retrospectively reviewed. Intraoperative bacterial culture results, used antimicrobial drugs and presence of SSI were recorded. RESULTS Ninety-eight dogs were included in the study. SSI rate was 10.2%. All dogs who developed SSI (n = 10) had negative intraoperative bacterial cultures. None of the dogs with positive intraoperative bacterial culture (n = 6) developed SSI. The most cultured bacteria causing SSI was Staphylococcus pseudintermedius (n = 4). CONCLUSIONS Intraoperative bacterial culture in dogs undergoing TPLO is not suitable as a predictor of surgical site infection.

Antimicrobial prophylaxis in companion animal surgery: A scoping review for European Network for Optimization of Antimicrobial Therapy (ENOVAT) guidelines. Vet J 2024; 304:106101. [PMID: 38490359 DOI: 10.1016/j.tvjl.2024.106101] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Revised: 03/09/2024] [Accepted: 03/10/2024] [Indexed: 03/17/2024]
Abstract
Surgical antimicrobial prophylaxis (SAP) is widely used to reduce the risk of surgical site infections (SSI), but there is uncertainty as to what the proportion of SSI reduction is. Therefore, it is difficult for surgeons to properly weigh the costs, risks and benefits for individual patients when deciding on the use of SAP, making it challenging to promote antimicrobial stewardship in primary practice settings. The objective of this study was to map the veterinary evidence focused on assessing the effect of SAP on SSI development and in order to identify surgical procedures with some research evidence and possible knowledge gaps. In October 2021 and December 2022, Scopus, CAB Abstracts, Web of Science Core Collection, Embase and MEDLINE were systematically searched. Double blinded screening of records was performed to identify studies in companion animals that reported on the use of SAP and SSI rates. Comparative data were available from 34 out of 39123 records screened including: eight randomised controlled trials (RCT), 23 cohort studies (seven prospective and 16 retrospective) and three retrospective case series representing 12476 dogs and cats in total. Extracted data described peri- or post-operative SAP in nine, and 25 studies, respectively. In the eight RCTs evaluating SAP in companion animals, surgical procedure coverage was skewed towards orthopaedic stifle surgeries in referral settings and there was large variation in SAP protocols, SSI definitions and follow-up periods. More standardized data collection and agreement of SSI definitions is needed to build stronger evidence for optimized patient care.

Abstract
OBJECTIVE To determine the incidence and severity of complications for subdermal plexus flaps in dogs and compare the complications when using sutures or staples for cutaneous closure of subdermal plexus flaps. STUDY DESIGN Retrospective monocentric study. SAMPLE POPULATION Ninety-seven client-owned dogs. METHODS Dogs that underwent wound reconstruction using subdermal plexus flaps were retrospectively identified. Type of flap, cutaneous closure technique, complications and level of complication associated with their use were recorded. Follow-up was considered adequate if it was more than 10 days postoperatively or until a complication occurred. RESULTS Complications were seen in 52 dogs (53.6%), of which 13/18 (72.2%) of dogs had cutaneous closure with skin staples versus 39/79 (49.3%) with skin sutures. The location of the mass/wound on the head and use of an advancement flap was associated with lower incidence of complications (p < .001; p = .018 respectively). Location of the mass/wound on the proximal pelvic limb was associated with a low level of complications (p = .01) on univariable analysis only. On multivariable analysis, only an increased bodyweight was associated with an increased incidence of complications (p = .029). CONCLUSIONS Increased weight may be associated with an increased risk of complications with subdermal plexus flaps. No risk factor was found to be associated with the severity of complications. CLINICAL SIGNIFICANCE Overall incidence of complications for subdermal plexus flaps in dogs in this study was 53.6%. The number of dogs included in the study was not sufficient to assess if the skin closure technique affects the incidence of complications.

Abstract
OBJECTIVE To determine the influence of preclosure antiseptic versus saline lavage on surgical site infections (SSI) in dogs following tibial plateau leveling osteotomy (TPLO). STUDY DESIGN A multicenter retrospective study. SAMPLE POPULATION Dogs treated with TPLO (n = 1422) between December 2019 and October 2021. METHODS The medical records of dogs treated with TPLO were reviewed for preclosure antiseptic lavage or saline irrigation. Additional collected data included signalment, unilateral or bilateral TPLO, postoperative administration of antimicrobial medications, antibiotic agent, surgeon, and development of SSI within 90 postoperative days. Eleven factors were analyzed for association with SSI using univariate and multivariate analysis. RESULTS Data were collected from the records of 519 dogs treated with antiseptic lavage and 903 dogs treated with saline lavage during TPLO. Surgical site infections were diagnosed more frequently in dogs that received preclosure antiseptic lavage (77/519, 14.84%) than those with saline irrigation (80/903, 8.86%) (p = .001). Single session bilateral TPLO increased the odds of SSI by 2.5x (p = .004). The odds of SSI increased by 11% (p = .001) for every 5 kg increase in bodyweight. Postoperative administration of antimicrobials decreased the risk of SSI (p = .008). CONCLUSION The preclosure antiseptic lavage tested here did not decrease the incidence of SSI after TPLO. CLINICAL SIGNIFICANCE The results of this study do not provide evidence to support preclosure antiseptic lavage during TPLOs.

Abstract
OBJECTIVE An increased rate of surgical site infection (SSI) following treatment of canine humeral intracondylar fissure (HIF) with a lateromedially (LM) placed transcondylar screw (TCS) compared with a mediolateral (ML) TCS has been previously postulated. We hypothesized that the direction of insertion of the TCS would not affect the incidence of postoperative SSI. STUDY DESIGN It was single-centre retrospective study. Dogs with HIF confirmed by computerized tomography, treated by TCS placement (between 2008 and 2019) and with a minimum follow-up of 12 weeks, were included. The following data were recorded: signalment, presenting clinical signs, direction of placement and size of the utilized TCS, surgical and anaesthetic times, concurrent surgical procedures, presence of concomitant elbow pathology, perioperative and postoperative antibiotic usage and postoperative complications. Recorded data were analysed with a multinomial logistic regression model with a p-value less than or equal to 0.05. RESULTS Thirty-five dogs (46 elbows) met the inclusion criteria. Median clinical follow-up interval was 52 weeks. Seven of thirty-one elbows with a ML TCS, and 4/15 elbows with a LM TCS developed SSI. Four of nine dogs that underwent bilateral single-surgery TCS placement developed SSI unilaterally. CONCLUSION No significant difference was shown in short-term SSI occurrence between the ML and the LM direction of placement of the TCS.

Abstract
The aim of this study was to determine the effect of oclacitinib (Apoquel) on development of surgical site infections in canines following clean orthopedic stifle surgery. Medical records of dogs undergoing unilateral, clean orthopedic stifle procedures were retrospectively examined for development of post-operative surgical site infections. Data collected for statistical analysis included age, sex, body weight, current medications, anesthesia and surgery times, white blood cell count, and neutrophil count. Surgical site infections were identified in 8.7% (34/390) of stifle procedures- 8.0% (29/364) in dogs not treated with oclacitinib and 19.2% (5/26) in dogs treated with oclacitinib (p = 0.053). There was a significant difference in development of surgical site infection in dogs with longer anesthesia times (p = 0.003) and higher body weights (p = 0.037). Dogs being treated with oclacitinib at the time of clean, orthopedic stifle surgery did not have a significantly higher incidence of surgical site infections. However, client education regarding risk of infection and increased patient monitoring post-operatively are recommended, especially in patients with increased body weight or longer anesthetic times.

Abstract
Appropriate use of perioperative antimicrobials can significantly reduce the risk of post-operative infections. However, inappropriate antimicrobial use can result in the creation of multidrug-resistant bacteria, increased costs, host flora disruption, side effects and increased risk of hospital-acquired infections. This survey evaluated the current perioperative use of antimicrobials in small animals by Spanish veterinarians using a web-based questionnaire. Responses were represented using descriptive statistics and a statistical analysis of the association between demographic data and perioperative antimicrobial use was performed. Pre-operative antimicrobials were administered in clean surgery by up to 68.3% of participants, 81.0% in clean-contaminated surgery and 71.3% in dirty surgery, while in the post-operative period, antimicrobials were administered by up to 86.3% of participants in clean surgery, 93.2% in clean-contaminated surgery and 87.5% in dirty surgery. Factors considered "very important" for antimicrobial selection were the degree of wound contamination, patient immunosuppression and use of prosthesis. The most frequently used antimicrobial was beta-lactamase-resistant (or potentiated) penicillin. Post-operative antimicrobial use was associated with participants without specific surgical postgraduate training. This study highlights an overuse of antimicrobials in perioperative procedures in small animal surgery in Spain. Therefore, evidence-based guidelines and further education regarding the correct use of antimicrobial prophylaxis are recommended.

Abstract
This study assessed the effects of concurrent intra-articular injection and Tibial Plateau Leveling Osteotomy (TPLO) plate surface treatment with leukoreduced platelet rich plasma (lPRP) on outcomes of dogs undergoing TPLO. A retrospective study of medical records for cases presenting from January 2018 to December 2020 was performed. Client-owned dogs with naturally occurring cranial cruciate ligament rupture that underwent TPLO surgery were divided into two groups. The lPRP group included cases that underwent intra-articular injection and plate surface treatment at the time of their TPLO. The control group (C) underwent TPLO without PRP treatment. Data analyzed included: presence of surgical site infection, implant removal rate, degree of change in OA progression score, lameness score progression and radiographic bone healing. The short- and long-term complication rate, hospitalization and antibiotic therapy were also compared between the groups. Descriptive statistics, comparison analyses (Chi square test, t-test, Fisher's exact test) and multi-level logistic regression models were used for statistical analysis. A total of 110 cases met the study inclusion criteria: 54 = lPRP, 56 = C. There were no significant differences between groups with regard to gender, age, presence of meniscal tear, weight, or body condition score. Significant findings included: improved radiographic healing of the osteotomy in the lPRP group, improved global OA scores in the lPRP group, and improved lameness score at recheck examination in the lPRP group. There was no significant difference between the lPRP and C group with regard to surgical site infection and implant removal rate. Concurrent intra-articular injection and plate surface treatment with leukocyte reduced PRP at the time of TPLO, is beneficial in slowing the progression of OA, hastening the radiographic evidence of osteotomy healing, and improved lameness score on recheck examination. Leukocyte reduced PRP was not a significant factor in reducing SSI or implant removal rate.

Abstract
BACKGROUND Excessive use of antimicrobials and the increasing occurrence of antimicrobial resistance are major challenges in both human and veterinary medicine. The role of prophylactic antimicrobial therapy in orthopaedic and neurosurgeries in dogs can be questioned. The aim of this study was to evaluate the rate of surgical site infections (SSI) and urinary tract infections (UTI) in dogs after cessation of antibiotics following spinal surgery. METHODS Electronic patient records from January 2018 to December 2019 were retrospectively reviewed to identify dogs that underwent spinal surgery (n = 158). Antimicrobial drug use and the presence of SSI and UTI were recorded. RESULTS Overall, SSI developed in 1.3% of dogs that underwent spinal surgery, while UTI developed in 8.2%. Multidrug-resistant (MDR) bacteria were detected in 5.1% of dogs. The rates of SSI, UTI and MDR did not differ significantly between dogs that received postoperative antimicrobial therapy and those that did not. LIMITATIONS The main limitation of this study was its retrospective design. CONCLUSION Overall, the SSI rate in this study was low. Cessation of postoperative antimicrobial use in dogs following spinal surgery did not have a negative effect on either SSI development or the occurrence of UTI.

Abstract
Objective To report surgical site infections (SSI) after Tibial Plateau Leveling Osteotomy (TPLO), treatment course, associated risk factors, bacterial isolates and antimicrobial resistance. Study design Retrospective clinical cohort study. Study population Six hundred and twenty seven dogs and 769 TPLO procedures. Methods Data from electronic medical records of dogs undergoing TPLO between 2005 and 2015 at a single institution have been retrospectively reviewed. A generalized mixed logistic regression was used to determine possible risk factors. The Chi-Square test of independence was used to examine the relationship between the isolation of multidrug-resistant (MDR) bacteria and the development of major infections undergoing additional surgical treatment. To assess the correlation between number of SSI and number MDR isolate per year, Pearson's correlation coefficient was calculated. Results The overall complication rate was 19.3% (n = 149). SSI was most frequent with 8.5% (n = 65). Major SSI occurred in 6.8% (n = 52) TPLO (80.0% SSI). Staphylococcus (S.) pseudintermedius (n = 37) and S. aureus (n = 10) were most frequently isolated. Multidrug-resistant bacteria were identified in 2.7% (n = 21) TPLO (32.3% SSI) but were not associated with major SSI (p = 0.426). There was a strong positive correlation between number of MDR isolates per year and number of SSI per year [r (9) = 0.79, p = 0.004]. Factors associated with SSI were previous TPLO in the contralateral stifle (p = 0.02, OR = 2.01, 95% CI = 1.11-3.64) and German Shepherd dogs (p = 0.035, OR = 4.41, 95% CI = 1.11-17.54). The use of non-locking implants was found to be protective (p = 0.02, OR = 0.179, 95% CI = 0.18-0.77). Clinical significance Infection with multidrug-resistant bacteria is an emerging problem in veterinary practice and treatment is challenging. The incidence of major SSI was found to be high but was not associated with the isolation of MDR bacteria.

Abstract
OBJECTIVE To compare the incidence of surgical site infection-inflammation in dogs undergoing elective orthopedic surgery of the stifle after draping with a single-layer Kraton elastic seal patient drape or conventional double-layer drapes. STUDY DESIGN Prospective clinical trial. SAMPLE POPULATION A total of 789 dogs. METHODS Dogs were assigned to one of two groups: (1) conventional draping with 4-corner drapes and an overlying patient drape (n = 390) or (2) a Kraton seal extremity patient drape without 4-corner drapes (n = 399). All dogs were evaluated for surgical site infection-inflammation by 21 days and 6 months postoperatively. RESULTS The distribution of surgical procedures did not differ between draping techniques and included tibial tuberosity advancement (TTA, n = 480), tibial plateau leveling osteotomy (TPLO, n = 10), extracapsular lateral suture (ECLS, n = 130), medial patellar luxation repair (MPL, n = 63), lateral patellar luxation repair (LPL, n = 1), ECLS/MPL (n = 68), TTA/MPL (n = 12), TTA with joint capsule biopsy (n = 1), and stifle arthroscopy combined with TTA or TPLO (n = 24). Duration of follow up was 180 days (range 3-180 days) for clinical examinations and 182 days (range 2-182 days) for phone communications. Infection-inflammation was documented in 9 dogs after double-layer draping and 11 dogs after single-layer draping at 21 days postoperatively and in 12 dogs after double-layer draping and 7 dogs after single-layer draping at 6 months postoperatively. CONCLUSION No difference in postoperative infection-inflammation was detected between canine stifle surgeries draped with a single-layer Kraton extremity patient drape or double-layer drapes. CLINICAL SIGNIFICANCE The single-layer Kraton extremity patient drape is a viable alternative to conventional double-layer draping in canine stifle surgery.

Abstract
OBJECTIVE To determine the incidence of and risk factors for surgical site infection (SSI) following canine thoracic and pelvic limb amputations. STUDY DESIGN Retrospective, multicenter study. ANIMALS Dogs (n = 248). METHODS Medical records were reviewed for preoperative, intraoperative, and postoperative variables including indication for amputation, amputation type, method of muscle transection, duration of surgery and anesthesia, and wound classification. Follow up was ≥30 days or until SSI development. Logistic regression and Fisher's exact tests were used to compare SSI incidence to variables of interest. RESULTS The incidence of SSI was 12.5% for all procedures and 10.9% for clean procedures. Factors increasing odds of SSI were muscle transection with a bipolar vessel sealing device (P = .023 for all procedures, P = .025 for clean procedures), procedure classified as other than clean (P = .003), and indication for amputation of bacterial infection (P = .041) or traumatic injury (P = .003) compared to neoplasia. CONCLUSION Use of bipolar vessel sealing devices for muscle transection increased the odds of developing an SSI whereas use of electrosurgery and/or sharp transection did not. Dogs with surgical sites that were other than clean, or with bacterial infection and/or traumatic injury were also at increased odds of SSI. CLINICAL SIGNIFICANCE Use of electrosurgery or sharp transection for muscle transection should be considered rather than use of bipolar vessel sealing devices to decrease odds of SSI in dogs undergoing limb amputation. Further studies across a variety of procedures are needed to validate these findings given the increasing popularity of these devices in veterinary medicine.

Abstract
The aim of this study was to evaluate the complications and the short-, medium-, and long-term outcomes following treatment of cranial cruciate ligament (CCL) rupture in dogs using the lateral fabello-tibial suture technique. The patients were ten dogs of various breeds, 62.5 ± 18.8 months of age, weighing 30.2 ± 3.3 kg, with unilateral CCL rupture. At 2, 6, 12, 24, and 52 weeks after surgery, the dogs were re-evaluated with clinical examination, gait and pain analysis, and radiography. A major complication was identified in one dog (10%), requiring second surgery due to implant failure and destabilisation of stifle joint. Minor complications occurred in two dogs postoperatively (one late meniscal injury and one case of seroma formation). The short-term outcome at two and six weeks postoperatively was considered good in six dogs and satisfactory in four dogs, while the mid-term outcome (between 12 and 24 weeks) was good to excellent in eight dogs and satisfactory in two dogs. All ten dogs had a good to excellent outcome 52 weeks after surgery. The lateral suture technique is generally safe and given the major benefits, such as lower costs, lower technical difficulty, and minimal requirement for specialised equipment, will probably remain a popular and alternative method for treatment of CCL insufficiency in dogs with good degree of owner satisfaction.

Biomechanical Comparison of Tibial Plateau Leveling Osteotomy Performed With a Novel Titanium Alloy Locking Plate Construct vs. an Established Stainless-Steel Locking Plate Construct. Front Vet Sci 2021; 8:698159. [PMID: 34568473 PMCID: PMC8455938 DOI: 10.3389/fvets.2021.698159] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Accepted: 06/24/2021] [Indexed: 11/14/2022] Open
Abstract
A novel canine tibial plateau leveling osteotomy (TPLO) fixation device was recently developed with design features such as titanium alloy (TA) material, distal monocortical screw fixation, and a point contact undersurface specifically targeted to reduce surgical site infection rates by ensuring tissue perfusion under the plate. The strength of the novel TPLO construct was compared with that of a predicate stainless steel (SS) locking plate construct with bicortical screws in 16 paired cadaveric canine limbs. The mean loads to failure were 716.71 ± 109.50 N (range 455.69–839.69 N) and 629.50 ± 176.83 N (range 272.58–856.18 N) in the TA and SS groups, respectively. The average ratio of the loads to failure of the paired specimens was 1.18 (p = 0.031). No failure of the TA constructs involved the distal fixation with monocortical screws. Substantial mechanical equivalence of this novel TA monocortical/bicortical fixation construct to an established SS bicortical screw fixation construct is demonstrated. Clinical investigation of potential merits of this novel TA, monocortical/bicortical locking screw/plate system is now warranted.

Abstract
The objective of this study was to report post-operative complications and outcomes in canines undergoing elbow arthrodesis (EA) with fixation techniques including bone plate fixation with a non-locking dynamic compression plate (DCP), bone plate fixation with a locking plate (LCP), and external skeletal fixator (ESF). Medical records of twenty-two cases that underwent EA between January 2009-December 2019 from 8 referral hospitals including both private practice and academic institutions were reviewed. Post-operative complications were classified as either minor or major, surgical evaluations were performed 8 weeks post operatively, and a follow-up questionnaire was sent to owners. Of the total 22 cases that met inclusion criteria, a total of 19/22 cases had complications, 12 major and 7 minor. Complications reported in 8/9, 7/9, and 4/4, for the DCP, LCP, and ESF fixation groups, respectively. Mild to moderate mechanical lameness was identified at surgical evaluation in 16/22 cases. Complete radiographic bone healing was achieved after 9 weeks in 19/22 cases. Long term owner follow up was available in 14/22 cases. Owners reported a good to normal quality of life in 13/14 cases and poor in one case. The majority of owners (11/14) reported good to excellent satisfaction with the outcome irrespective of persistent lameness. This study demonstrates that successful EA can be achieved using a variety of fixation methods, but persistent lameness is expected and complication rate is high.

Abstract
OBJECTIVE To analyze the effect of surgical technique and other risk factors on severe postoperative complications in dogs with cranial cruciate ligament disease (CCLD). MATERIALS AND METHODS A cohort study of 255 dogs (287 stifles) surgically treated for CCLD at two veterinary university hospitals (2011-2016) was performed. The electronic medical records were reviewed and dog owners and referring veterinarians contacted for additional information. The complications were classified as minor, major and catastrophic, where major and catastrophic were considered severe. A multivariable Cox proportional hazards model was applied to assess risk factors for severe postoperative complications. RESULTS Three surgical techniques were used; lateral fabellotibial suture (LFS, 141 stifles), tibial plateau leveling osteotomy (TPLO, 77 stifles) and tibial tuberosity advancement (TTA, 69 stifles). The most common severe postoperative complications were surgical site infections or complications related to the surgical implant. Severe postoperative complications occurred in 31 % of the stifles treated with TPLO, 22 % of the stifles treated with LFS and 25 % of the stifles treated with TTA. The multivariable Cox proportional hazards model identified surgical technique (p = 0.0258) as a risk factor for severe postoperative complications; TPLO had a significantly lower hazard than LFS (hazard ratio (HR) = 0.37, p = 0.007) when controlling for body weight and age, which also were identified as risk factors (HR = 1.05, p < 0.001 and HR = 0.91, p = 0.047, respectively). CONCLUSION AND CLINICAL RELEVANCE Although TPLO procedures had the highest occurrence of severe postoperative complications, the hazard was lower than for LFS after adjusting for body weight and age. This implies that it is important to consider potential effect-modifiers when comparing postoperative complications after CCLD surgery.

Abstract
OBJECTIVE A systematic review of published data to determine whether postoperative antibiotic use after tibial plateau leveling osteotomy (TPLO) decreases infection rates. STUDY DESIGN Systematic review. METHODS A broad bibliographic search was performed in three online databases through March 2020 for publications on postoperative antibiotic use after TPLO in dogs. Search terms included dog, canine, TPLO, tibial plateau leveling osteotomy, infection, antibiotic, and antimicrobial. Articles that met inclusion criteria were evaluated for level of evidence (LoE) by a modified Oxford Level of Evidence (mOLE) and GRADE (Grading of Recommendations, Assessment, Development and Evaluation) classification and evaluation. RESULTS Thirteen studies met the inclusion criteria. Effect of antibiotic use was the primary question in four studies. Among those, 50% (2/4) were assigned a mOLE of 1b and a GRADE of moderate, while the other 50% (2/4) were assigned a mOLE of 4b or 4c with a GRADE of low. The two studies with the highest LoE did not provide evidence of the benefit of antibiotic usage. Results of only one study provided evidence to support the use of postoperative antibiotics. The remaining nine studies provided evaluation of antibiotic use secondarily and were all assigned a low LoE. Among these, 78% (7/9) provided evidence to support the use of postoperative antibiotics. CONCLUSION We found little evidence to support the use of postoperative antibiotics to reduce the risk of surgical site infections in dogs after TPLO. The answer to this clinical question is complicated by the lack of prospective studies and inconsistent treatment protocols in the evaluated studies. CLINICAL SIGNIFICANCE The clinical impact of postoperative antibiotic administration on infection rates after TPLO is uncertain.

Abstract
OBJECTIVE This study investigated variables associated with surgical site infection (SSI) in dogs with cranial cruciate ligament rupture managed with stifle joint examination and lateral fabellotibial suture stabilization. STUDY DESIGN A retrospective study of dogs that had stifle arthroscopy, stifle arthrotomy, or a combination of both, followed by lateral fabellotibial suture stabilization for cranial cruciate ligament rupture. All cases had a minimum follow-up of 90 days. Lameness grades were recorded preoperatively, and at 6-week and final follow-up. RESULTS One hundred fifty procedures in 130 dogs met the inclusion criteria. Overall, SSI rate was 17.3% and removal of the lateral fabellotibial suture was performed in 53% of SSI. Multivariable analysis showed significant association between SSI and bodyweight (p = 0.013), and induction using propofol (p = 0.029). Multilevel ordinal logistic regression analysis showed a greater proportion of dogs had a higher lameness grade at 6-week (p = 0.021) and final follow-up (p = 0.002) assessments in the infected compared with non-infected dogs. CONCLUSION Our study demonstrated a higher SSI incidence than previously reported in dogs undergoing a lateral fabellotibial suture for cranial cruciate ligament rupture. Bodyweight and induction with propofol were identified as significant risk factors for postoperative SSI. Owners could be advised of an increased SSI risk in larger dogs and consideration should be given to selection of induction agent. Dogs that develop an SSI have a worse lameness grade at 6-week and final follow-up.

Antimicrobial prophylaxis is considered sufficient to preserve an acceptable surgical site infection rate in clean orthopaedic and neurosurgeries in dogs. Acta Vet Scand 2020; 62:53. [PMID: 32943076 PMCID: PMC7495856 DOI: 10.1186/s13028-020-00545-z] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2020] [Accepted: 08/24/2020] [Indexed: 11/18/2022] Open
Abstract
Background Surgical site infections (SSI) are associated with increased morbidity and mortality. To lower the incidence of SSI, antimicrobial prophylaxis is given 30–60 min before certain types of surgeries in both human and veterinary patients. However, due to the increasing concern of antimicrobial resistance, the benefit of antimicrobial prophylaxis in clean orthopaedic and neurosurgeries warrants investigation. The aims of this retrospective cross-sectional study were to review the rate of SSI and evaluate the compliance with antimicrobial guidelines in dogs at a veterinary teaching hospital in 2012–2016. In addition, possible risk factors for SSI were assessed. Results Nearly all dogs (377/406; 92.9%) received antimicrobial prophylaxis. Twenty-nine dogs (7.1%) did not receive any antimicrobials and only four (1.1%) received postoperative antimicrobials. The compliance with in-house and national protocols was excellent regarding the choice of prophylactic antimicrobial (cefazolin), but there was room for improvement in the timing of prophylaxis administration. Follow-up data was available for 89.4% (363/406) of the dogs. Mean follow-up time was 464 days (range: 3–2600 days). The overall SSI rate was 6.3%: in orthopaedic surgeries it was 6.7%, and in neurosurgeries it was 4.2%. The lowest SSI rates (0%) were seen in extracapsular repair of cranial cruciate ligament rupture, ulnar ostectomy, femoral head and neck excision, arthrotomy and coxofemoral luxation repair. The highest SSI rate (25.0%) was seen in arthrodesis. Omission of antimicrobials did not increase the risk for SSI (P = 0.56; OR 1.7; CI95% 0.4–5.0). Several risk factors for SSI were identified, including methicillin-resistant Staphylococcus pseudintermedius carriage (P = 0.02; OR 9.0; CI95% 1.4–57.9) and higher body temperature (P = 0.03; OR 1.69; CI95% 1.0–2.7; mean difference + 0.4 °C compared to dogs without SSI). Conclusions Antimicrobial prophylaxis without postoperative antimicrobials is sufficient to maintain the overall rate of SSI at a level similar to published data in canine clean orthopedic and neurosurgeries.

Abstract
OBJECTIVE To determine the prevalence of subclinical bacteriuria (SBU) in dogs with cranial cruciate ligament (CCL) disease, the clinical variables and clinicopathologic data associated with SBU, and the incidence of surgical site infections (SSI) in dogs with and without SBU. STUDY DESIGN Prospective, clinical cohort study. ANIMALS One hundred fifty-five dogs with CCL disease. METHODS Dogs had a urinalysis, sediment examination, and aerobic urine culture performed. Age, breed, sex, body weight, body condition score, clinical history, and physical examination findings were recorded. Dogs with SBU were not treated for bacteriuria or with postoperative antibiotics. Standard perioperative antimicrobials were provided for all dogs. Dogs that received nonsteroidal anti-inflammatory drugs were not excluded. Dogs that underwent an osteotomy were followed for at least 1 year to determine incidence of SSI. Outcomes and variables associated with SBU were assessed. RESULTS In 155 dogs with CCL disease, the prevalence of SBU was 6.5%, and SBU occurred exclusively in female dogs (11.4%). The incidence of SSI was 22.3% (25/112). Two of six dogs with SBU and 23/106 dogs without SBU developed SSI. Organisms isolated from SSI were different from those isolated from urine. CONCLUSION The prevalence of SBU in dogs with CCL disease was similar to that in other studies in which SBU was evaluated in various populations of dogs. CLINICAL SIGNIFICANCE Screening for and treatment of SBU may not be beneficial prior to tibial osteotomy for CCL disease. Additional studies are required to determine whether dogs with SBU have a greater risk of SSI.

Abstract
Background Cranial cruciate ligament rupture (CrCLR) is the most common orthopaedic cause of lameness in the hind limb in dogs. Many surgical treatments have been described, but tibial tuberosity advancement (TTA) is one of the most commonly used today. Since it was first described, TTA has evolved to reduce major complications and to arrest the progression of osteoarthrosis. The aim of this study was to assess a surgical technique called Porous TTA with flange prospectively. This study was performed in 61 dogs that underwent 65 Porous TTA with flange procedures, to validate it as an alternative CrCLR treatment. Complications and clinical outcomes (pain, lameness, weight bearing, flexion, extension, crepitation and atrophy) were reported over 3 months, i.e. at 3, 6 and 12 weeks postoperatively. Results The results showed a positive clinical outcome, a minor complication rate of 47.69% at the first review 3 weeks postoperatively, 10.77% at the second one (6 weeks after the surgery) and 4% at the third one (at 12 weeks). Major complications were observed only at the last review, with one case that had an infection requiring implant removal; this represented 1.5% of cases. Variables evaluated for a relationship with complication scores and improvement were body condition score, sex, age, breed, body weight, breed size, side of the affected limb, traumatic anamnesis and time of lameness before surgery. No relationship was detected. Conclusions Clinical outcomes and complications show that Porous TTA with flange is an efficient alternative for surgical treatment of CrCLR in dogs.

Abstract
ABSTRACT Surgical site infections (SSIs) and antimicrobial resistance among pathogens causing SSI are a growing concern in veterinary hospitals. One major reason, the widespread use of antimicrobials, has led to increased incidence of SSIs. This study identified bacteria and resistance profiles to antimicrobials in the SSI cases diagnosed at the Surgical Clinic of Small Animals in the Veterinary Hospital, Federal University of Viçosa, Brazil. The main genus identified was Staphylococcus, followed by Escherichia, Enterococcus, Bacillus, Shigella, Citrobacter, Proteus, Morganella, Serratia, Enterobacter, Pseudomonas and Klebsiella were also found, but in small number. The results indicated the predominance of Gram-negative bacteria among the collected samples. Most of isolates identified were resistant to more than one of the following antimicrobials: ampicillin, tetracycline, enrofloxacin, amoxicillin/clavulanic acid and cephalotin. Of the 17 Staphylococcus sp. isolates, two (11.8%) were methicillin-resistant Staphylococcus aureus (MRSA) and 11 (64.7%) of them were methicillin-resistant Staphylococcus pseudintermedius (MRSP). There were bacterial genera identified with resistance to all tested antimicrobials in different proportions. This should alert veterinary hospitals to the emergence of multidrug-resistant bacteria and to the requirement for the revision of surgical protocols with regard to antimicrobial prophylaxis and therapy.

[PMID: 32196706 DOI: 10.1111/vsu.13413] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2019] [Revised: 02/23/2020] [Accepted: 03/01/2020] [Indexed: 11/28/2022]
Abstract
OBJECTIVE To evaluate the presence of quaternary ammonium compound (QAC) (resistance genes, qac A/B, smr, qacG, and qacJ, in clinical isolates of methicillin-susceptible Staphylococcus pseudintermedius (MSSP) and methicillin-resistant S pseudintermedius (MRSP) from dogs and the impact on in vitro chlorhexidine susceptibility. STUDY DESIGN Experimental in vitro study. SAMPLE POPULATION Seventy isolates from dogs colonized or infected with MRSP (n = 50) or MSSP (n = 20). METHODS Agar dilution was used to determine the minimum inhibitory concentration (MIC) of chlorhexidine digluconate. Real-time polymerase chain reaction was used to detect the presence of QAC resistance genes, qacA/B, smr, qacG, and qacJ genes. RESULTS One or more qac genes were identified in 52 of 70 (74%) isolates. Overall, there was no association between chlorhexidine MIC and the presence of one or more qac genes (P = .85) or the presence of qacA/B (P = .31), smr (P = .72) or qacJ (P = .93) individually. There was an association between qacG and MIC (P = .012), with a median MIC of 1.5 μg/mL for isolates possessing this gene and 1 μg/mL for those not possessing it. CONCLUSION Quaternary ammonium compound resistance genes were present in MRSP and MSSP isolates. With the exception of qacG, the presence of these genes was not associated with increased MIC. All isolates exhibited MIC 5000 to 80 000 times lower than the concentration recommended for use. CLINICAL SIGNIFICANCE Despite the presence of QAC genes, chlorhexidine digluconate should be effective against MRSP and MSSP if used correctly.

Abstract
OBJECTIVE To determine the influence of prophylactic administration of oral antimicrobial medications after tibial plateau leveling osteotomy (TPLO) on surgical site infections (SSI) and antimicrobial-resistant infections. STUDY DESIGN Retrospective study. SAMPLE POPULATION Dogs treated with unilateral TPLO (n = 308) between January 2013 and December 2015. METHODS Medical records were reviewed for signalment, surgically treated limb, duration of surgery and anesthesia, postoperative administration of antimicrobial medications, antibiotic agent, surgeon, and development of SSI. Statistical analyses included descriptive statistics, simple linear regression, analysis of variance, Fisher's protected least significant difference, and χ2 testing. RESULTS Data were collected from records of 31 dogs that did not receive antimicrobial medications and 277 dogs that did receive oral antimicrobial medications for 14 days after TPLO. Superficial incisional SSI was detected in two of 31 dogs that did not receive antimicrobial medications and in 48 of 277 dogs that did receive antimicrobial medications (P = .1194). Deep incisional SSI occurred in two of 31 dogs that did not receive antimicrobial medications and in 27 of 277 dogs that did receive antimicrobial medications (P = .5513). Antibiotic-resistant deep incisional SSI occurred in two of 31 dogs that did not receive antimicrobial medications and in 18 of 277 dogs that did receive antimicrobial medications (P = .9920). Body weight correlated with deep incisional SSI and resistant infections. Prolonged duration of surgery and anesthesia were associated with superficial incisional SSI, deep incisional SSI, and antibiotic resistance. Surgeons influenced deep incisional SSI. CONCLUSION Previously reported predisposing factors for infection were confirmed, but postoperative administration of antimicrobial medications was not protective against SSI nor did it predispose to antibiotic resistance in our clinical setting. CLINICAL SIGNIFICANCE This study does not provide evidence to support administration of prophylactic oral antimicrobial medications after unilateral TPLO.

Abstract
Objectives To determine (1) the incidence of surgical site infection (SSI) in patients undergoing soft tissue surgery at a veterinary teaching hospital and to study (2) and describe the main risk factors associated with SSI and (3) assess the economic impact of SSI. Design Prospective cohort study. Setting Veterinary teaching hospital. Participants 184 dogs undergoing soft tissue surgery during a 12-month period (October 2013 to September 2014). Primary outcome measure Surgical site infection. Results Out of the 184 patients analysed, SSI was diagnosed in 16 (8.7 per cent) patients, 13 (81.3 per cent) were classified as superficial incisional infection, 2 (12.5 per cent) as deep incisional infection and 1 (6.3 per cent) as organ/space infection. The administration of steroidal anti-inflammatory drugs (P=0.028), preoperative hyperglycaemia (P=0.015), surgical times longer than 60 minutes (P=0.013), urinary catheterisation (P=0.037) and wrong use of the Elizabethan collar (P=0.025) were identified as risk factors. Total costs increased 74.4 per cent, with an increase in postsurgical costs of 142.2 per cent. Conclusions The incidence of SSI was higher than the incidence reported in other published studies, although they were within expected ranges when a surveillance system was implemented. This incidence correlated with an increase in costs. Additionally new important risk factors for its development were detected.

Abstract
AIMS To compare stainless steel staples and polypropylene suture material for primary closure of wounds after teat amputation in ewes and to assess progress of healing in the presence or absence of intramammary infection (IMI). METHODS Chios-cross ewes, aged 3-5 years were randomly allocated to be infected in one teat with 1,200-1,500 cfu of Mannheimia haemolytica 5 days after parturition (groups A and B; n = 8 in each group) or remain uninfected (groups C and D; n = 4 in each group). On the following 4 days one teat from each ewe was amputated 2.5 cm from the teat end and the wound was closed using skin staples (groups A and C) or polypropylene sutures (groups B and D). Clinical evaluation of wound healing was performed between 1-21 days after surgery. On day 21 tissue sections were collected for tensiometric and histological evaluation. RESULTS The mean interval from the start to finish of wound closure was shorter when staples were used than when sutures were used (p < 0.001). Healing scores were lower (improved) for ewes in group A than B between days 1-7 after surgery (p = 0.005), but were similar between days 10-21 (p = 0.43). Healing scores were similar in groups C and D (p = 0.98). The tensile strain at maximum load was higher in tissue from group A than B (p = 0.001) and D (p = 0.004), but all other tensiometric measures were similar between groups. Histologically, collagen density was higher in sections from group A than B (p = 0.05) and D (p = 0.01), and angiogenesis was lower in sections from group A than B (p = 0.03) and D (p = 0.01). CONCLUSIONS AND CLINICAL RELEVANCE Skin staples and polypropylene sutures can be used effectively for primary closure of teat wounds, even in the presence of IMI. Skin staples had the advantage of a reduction in surgical time. ABBREVIATION IMI: intramammary infection.

Abstract
OBJECTIVE To compare surgical site infection (SSI) rates after double locking plate and screw fixation (DLP), standard locking plate and screw fixation (LP), and conventional nonlocking plate and screw fixation (NLP) in dogs weighing >50 kg undergoing tibial plateau leveling osteotomy (TPLO). STUDY DESIGN Retrospective study (January 2003-October 2017). ANIMALS Two hundred seventy-five dogs weighing >50 kg with cranial cruciate ligament disease treated with TPLO. METHODS Medical records of dogs weighing >50 kg that underwent TPLO by DLP, LP, and NLP with a minimum follow-up period of 12 months were included. Data collected included signalment, details of any concurrent surgical procedure, type of implant used, use of postoperative antibiotic therapy, occurrence of perioperative complications, and presence of postoperative infection. The probability, risk difference, and relative risk of SSI were estimated for each fixation with a marginal model. RESULTS Nonlocking plate and screw fixation was used in 114 (41.5%) dogs, LP was used in 128 (46.5%) dogs, and DLP was used in 33 (12%) dogs. Surgical site infection was diagnosed in 48 of 275 (17.5%) dogs. Postoperative antibiotic therapy was used in 74 (64.9%) dogs, 62 (48.4%) dogs, and 32 (97.0%) dogs in the NLP, LP, and DLP groups, respectively. Dogs with NLP, LP, and DLP had postoperative infection rates of 24.5%, 13.3%, and 9.1%, respectively. There were no risk differences for the three groups (Holm-adjusted P > .05). CONCLUSION No difference in infection rates was detected between DLP, LP, or NLP for TPLO in these dogs weighing >50 kg. CLINICAL SIGNIFICANCE Fixation of TPLO with DLP in dogs weighing >50 kg does not seem to increase the risk of SSI compared with LP and NLP.

Abstract
The Australian Veterinary Prescribing Guidelines for antimicrobial prophylaxis for surgery on dogs and cats are evidence-based guidelines for veterinary practitioners. Validation of these guidelines is necessary to ensure quality and implementability. Two validated tools, used for medical guideline appraisal, were chosen to assess the guidelines. The terminology from the GuideLine Implementability Appraisal (GLIA) and the Appraisal of Guidelines for Research and Evaluation version 2 (AGREE II) were adapted for use by veterinarians. A two-phase evaluation approach was conducted. In the first phase of the evaluation, the GLIA tool was used by two specialist veterinary surgeons in clinical practice. The results of this phase were then used to modify the guidelines. In the second phase, the AGREE II tool was used by 6 general practitioners and 6 specialists to appraise the guidelines. In phase 1, the specialist surgeons either agreed or strongly agreed that the guidelines were executable, decidable, valid and novel, and that the guidelines would fit within the process of care. The surgeons were neutral on flexibility and measurability. Additional clarity around one common surgical procedure was added to the guidelines, after which the surgeons agreed that the guidelines were sufficiently flexible. In phase 2, 12 veterinarians completed the assessment using the AGREE II tool. In all sections the scaled domain score was greater than 70%. The overall quality of the guidelines was given a global scaled score of 76%. This assessment has demonstrated that the guidelines for antimicrobial prophylaxis for companion animal surgery are valid and appear implementable.

Abstract
OBJECTIVE To report the use of the genicular artery axial pattern flap and the frequency and severity of complications in a consecutive series of clinical cases. MATERIALS AND METHODS Medical records from one referral centre were retrospectively reviewed for cases requiring reconstruction using a genicular axial pattern flap between January 2012 and February 2018. RESULTS Twenty-two dogs were included. Skin defects ranging from 12.6 to 81 cm2 (mean 32 cm2 ) on the lateral and cranial crus were successfully closed using the genicular artery axial pattern flap. Average flap survival was 99.1% with two dogs developing distal flap necrosis. Minor complications occurred in eight dogs (36%) including minor wound dehiscence, seroma formation and infection. Major complications requiring further surgery occurred in three dogs (13.6%). CLINICAL SIGNIFICANCE The genicular artery axial pattern flap is useful in the reconstruction of small- to medium-sized skin defects of the lateral and cranial crus. The flap may be more robust and offer better viability than reported previously in experimental studies.

Abstract
OBJECTIVE To report the use and long-term outcome of dogs with surgical site infection (SSI) after tibial plateau leveling osteotomy (TPO), treated with an amikacin-infused collagen sponge and implant removal. STUDY DESIGN Retrospective study. ANIMALS Thirty-one client-owned dogs. METHODS Medical records were reviewed for dogs with SSI after a TPLO that were treated with surgical implant removal and concurrent implantation of an amikacin-infused collagen sponge. Relevant clinical and surgical data were recorded. The TPLO implants were routinely removed; the surgical site was swabbed for culture. The sponge was aseptically infused with amikacin prior to implantation. Postprocedure examinations consisted of visual inspection of the incision by the surgeon and lameness scoring. RESULTS Thirty-one dogs met all inclusion criteria. Median follow-up time was 687 days. Short-term examination after implant removal and sponge implantation revealed uneventful incisional healing in 24 dogs. Six (19.4%) dogs exhibited inflamed incision sites a median of 4 days (range, 3-9) postoperatively that resolved without additional treatment. One (3.2%) dog required empirical antibiotic treatment 7 days postoperatively but was lost to long-term follow-up. Long-term follow-up examination revealed no clinical evidence of SSI recurrence and no lameness in the remaining 30 cases. CONCLUSION Surgical implant removal and implantation of an absorbable collagen sponge infused with amikacin alone was an effective treatment for postoperative TPLO SSI. CLINICAL SIGNIFICANCE This procedure had a 96.8% long-term resolution of SSI. It should be considered as a treatment option for TPLO SSI.

Abstract
OBJECTIVE To report infection rate, implant removal rate, and postoperative antibiotic therapy after tibial tuberosity advancement (TTA) in dogs. STUDY DESIGN Retrospective study. ANIMALS One thousand seven hundred sixty-eight stifles in 1,732 dogs. METHODS Medical records (January 2007-December 2011) of dogs treated with a TTA were reviewed. Cases were included if at least 1 year of postoperative follow-up was available and no additional procedures were performed on the stifle. Date of surgery, date of culture, culture and susceptibility results, postoperative antimicrobials used, and any implant removals were recorded. Use of postoperative antibiotics and implant removal were evaluated statistically for effect on infection occurrence and resolution. RESULTS Postoperative infections were diagnosed in 82 of 1,768 (4.6%) stifles. Implants were removed from 32 (39%) stifles, with plate and screw removal only in 23 (71.9%) stifles. The rate of infection did not differ between dogs with or without postoperative antibiotic therapy. However, dogs receiving postoperative antibiotic therapy were at risk for developing an oxacillin-resistant infection (P = .001). Oxacillin-resistant infections were associated with a requirement for implant removal to achieve resolution compared with other types of bacterial infections (P < .05). CONCLUSION No benefit was detected with the use of postoperative antibiotics after TTA in this population. Implant removal was infrequent, and the requirement for cage removal was not commonly required for infection resolution. CLINICAL SIGNIFICANCE This study does not provide evidence to support postoperative antibiotic therapy after TTA. Postoperative infection can be treated in most dogs without removal of the TTA cage.

Abstract
Introducción: las infecciones nosocomiales son aquellas adquiridas por los pacientes durante la hospitalización. Son de gran importancia en medicina humana pero aún se desconoce cuál es su papel en medicina veterinaria.Objetivo: identificar la presencia de bacterias asociadas a infecciones hospitalarias en ambientes y superficies en una clínica veterinaria.Materiales y métodos: se realizaron dos muestreos, se determinó a través de sedimentación y torunda la presencia de bacterias en el ambiente y las superficies de las 8 unidades de la clínica veterinaria. La presencia de nosocomiales se determinó por el crecimiento y purificación en medios diferenciales, la identificación se hizo por descripción macroscópica de las colonias y tinción de Gram y posteriormente se realizó una caracterización bioquímicamente por medio del API20E y API50 CH/E y un antibiograma en las cepas relacionadas con resistencia a antibióticos.Resultados: se obtuvo 95 aislados y se logró determinar la presencia de 28 agentes potencialmente nosocomiales, donde se destaca la presencia de Pseudomonas aeruginosa, Proteus sp. y Staphylococcus sp. microorganismos relacionados con infecciones asociadas a hospitales veterinarios.Conclusiones: se realiza la primera aproximación a este tipo de infecciones en hospitales veterinarios en Antioquia, y se evidencia la circulación en ambiente y superficies de potenciales bacterias nosocomiales en la clínica veterinaria.

Abstract
OBJECTIVE To compare the use of stainless steel staples with absorbable staples for closure of skin incisions in dogs undergoing tibial plateau leveling osteotomy (TPLO). STUDY DESIGN Prospective study. SAMPLE POPULATION Client-owned dogs (n = 80). METHODS With client consent, dogs were randomly assigned a staple type (stainless steel or absorbable) immediately prior to closure of a TPLO skin incision. Incisions were compared for length, staple type and number, and an inflammation-infection score 2 weeks after surgery. RESULTS Overall, 18.8% of incisions were diagnosed with inflammation or infection. No difference was found between inflammation-infection scores, incision length, number of staples used, or general anesthetic time between the 2 staple groups. However, wound closure was faster with stainless steel staples (22.50 seconds; range, 11-180) by approximately 30 seconds compared with absorbable staples (56.50 seconds; range, 18-190; P < .001). Time taken to close the incision correlated negatively with the number of occasions that absorbable staples were used (P = .01). CONCLUSION Absorbable skin staples were successfully used to close skin incisions after TPLO and were not associated with an increased level of inflammation or infection in our clinical setting. CLINICAL SIGNIFICANCE Absorbable staples may be considered to close surgical wounds when subsequent suture removal would be impractical, without specific concerns over inflammation or infection of the wound.

A prospective, randomized, double-blinded, placebo-controlled clinical study on postoperative antibiotherapy in 150 arthroscopy-assisted tibial plateau leveling osteotomies in dogs. Vet Surg 2018; 47:E79-E87. [PMID: 30267441 DOI: 10.1111/vsu.12958] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2017] [Revised: 01/27/2018] [Accepted: 02/14/2018] [Indexed: 11/29/2022]
Abstract
OBJECTIVE To determine the influence of a 7-day course of postoperative antibiotherapy (cefpodoxime) on surgical site infections (SSI) after tibial plateau leveling osteotomy (TPLO). STUDY DESIGN Prospective, randomized, double-blinded, placebo-controlled clinical study. SAMPLE POPULATION One hundred fifty client-owned dogs, with consent. METHODS Dogs undergoing arthroscopy-assisted TPLO were randomly assigned to 1 of 2 groups, the placebo group receiving perioperative cefazolin and 7 days of placebo medication after surgery or the treatment group receiving perioperative cefazolin and 7 days of postoperative cefpodoxime. Twenty-seven factors were analyzed for association with SSI by using univariate analysis, Fisher's exact test, or Wilcoxon rank-sum test. RESULTS SSI rates did not differ (P = .34) between the placebo group (17%; 95% confidence level [CL] 7.94%-26.43%) and the treatment group (11% SSI; 95% CL 3.98%-18.88%). The probability that > 23% of dogs would benefit from postoperative antibiotherapy was less than 5%. The only association between the factors tested in this study and SSI involved the body weight (kg), with each 1 unit increase in kilogram weight increasing the odds of developing an SSI by 4.7%. CONCLUSION Although the wide CL may be consistent with a type II error, a 7-day course of cefpodoxime after arthroscopy-assisted TPLO did not influence postoperative SSI in the population tested here. In addition, only a small proportion of dogs would benefit from postoperative antibiotherapy under the conditions of our study. CLINICAL SIGNIFICANCE These results should prompt surgeons to reconsider systematic antibiotherapy after TPLO and justify additional studies to determine whether dogs predisposed to infection could benefit from such an approach.

Abstract
Background Cranial cruciate ligament rupture is a prevalent injury in dogs, and tibial plateau leveling osteotomy (TPLO) is one of the preferred surgical techniques. Surgical site infection is a possible complication following TPLO and measurement of serum acute phase proteins is suggested to be a way to early recognize and distinguish postoperative infectious complications from normal postoperative inflammatory conditions. In this study we investigate the changes in concentrations of the systemic inflammatory markers C-reactive protein (CRP) and serum amyloid A (SAA) following tibial plateau leveling osteotomy (TPLO) in dogs and evaluate if deviations from the changes expectedly induced by the surgical procedure are useful in early detection of post-surgical infections. Dogs with cranial cruciate ligament injuries treated by TPLO at the Region Animal Hospital of Helsingborg during 2012 were included. Dogs with concurrent diseases, other orthopedic problems, or noninfectious post-surgical complications were excluded. Serial measurements of CRP and SAA concentrations were made. Changes in concentrations were visualized graphically and the discriminative capacity to detect infectious post-surgical complications was tested at different time points. Results A characteristic pattern of changes in concentrations of CRP and SAA were observed following TPLO with a significant increase 24 h post-surgery in all dogs and baseline-concentrations re-established at day 12. In dogs that developed post-surgical infections, a deviation in form of significantly higher concentrations of CRP and SAA were observed at day 6, compared to un-complicated cases. High-discriminative clinical decision limits of CRP (43.9 mg/L) and SAA (63.8 mg/L) could be established for differentiation of dogs with and without clinical signs of infectious complications at day 6 post-operatively, applicable to reliably rule out presence of infectious complications due to very high sensitivity (no false negatives). Conclusions The CRP and SAA levels in dogs with clinical signs of post-surgical infectious complication deviated from the typical levels expected at day 6 after surgery, and clinical decision limits to reliably rule out presence of infectious complications was suggested.

Abstract
SummaryObjective: To report clinical experiences with the tibial plateau levelling osteotomy (TPLO) procedure in small breed dogs with cranial cruciate ligament (CCL) disease using specific, conically coupled, 1.9/2.5 mm locking plates and evaluating short-term complications and outcome.Methods: Medical records of small breed dogs (<15 kg) that underwent TPLO using 1.9/2.5 mm locking plates were reviewed retrospectively. The preoperative, postoperative and six to eight weeks postoperative tibial plateau angle (TPA) measurements were determined from the radiographic images. Lameness evaluation was assessed subjectively preoperatively and six to eight weeks postoperatively.Results: Sixty-nine small breed dogs (n = 79 stifles) were included in the study. Mean (± SD) preoperative TPA was 29.0 ± 3.4°, postoperative TPA was 5.8 ± 2.5°, and six to eight weeks postoperative TPA was 7.3 ± 4.1°. Sixteen complications occurred in 12 out of 79 TPLO procedures: three were intra-operative (intra-articular screw placement) and 13 were postoperative complications, of which nine were identified as minor complications not requiring surgical reintervention, and four as major complications requiring additional surgical intervention, including tibial tuberosity fracture (n = 1), osteomyelitis (n = 1), screw failure (n = 1), and plate breakage (n = 1). Lameness scores by clinical assessment reduced from a median value of 3/4 preoperatively to 1/4 at six to eight weeks postoperatively.Clinical significance: 1.9/2.5 mm locking plates appear to be a valid choice of implant for the stabilization of unilateral TPLO in small breed dogs.

Abstract
SummaryObjective: To evaluate the use of sonication to improve recovery of bacteria from metal discs infected with bacteria commonly associated with implant infections in veterinary medicine.Methods: In vitro study in which sterile titanium (Ti6Al4V) and stainless steel (AIS1316-L) discs were incubated with either Staphylococcus pseudintermedius or Pseudomonas aeruginosa for 24 hours. The following three groups were compared: 1) the sonication group involved immersing the discs in sterile saline and sonicating for five minutes; 2) the sham group was considered a negative control in which the discs were immersed in saline for five minutes without sonication; and 3) the swab group involved systematically swabbing the implant with a sterile culturette. All samples were plated on blood agar and incubated for 24 hours. Colonies were then counted and compared.Results: For both species of bacteria, there was a significant increase in bacterial colonies isolated using sonication compared to the other two study groups (p = 0.0001). No differences in bacterial growth were found between the two types of metal implants. There was a significant increase in bacterial colony counts for S. pseudintermedius when comparing the swab group versus the sham group, but this was not significant for P. aeruginosa.Clinical significance: Sonication significantly improves recovery of bacteria commonly associated with veterinary implant-associated surgical site infections compared to swabbing of implants in vitro. A prospective clinical evaluation is indicated to determine the in vivo efficacy of sonication in veterinary patients.

Abstract
SummaryObjective: To compare complication rates as well as the short and long-term function of surgical limbs in small dogs with bilateral medial patellar luxation (MPL) undergoing unilateral or single-session bilateral surgery.Methods: Dogs weighing less than 12 kg with bilateral MPL that underwent unilateral (group U) or single-session bilateral surgery (group B) were retrospectively analysed. Data analysed included signalment, grades of luxation, surgical procedures, duration of surgery and anaesthesia, use of antibiotic medications, hospitalization time, complications, function at short-term follow-up, bone healing, and long-term assessment of function by means of a questionnaire.Results: Twenty-four dogs were included in group U and 27 in group B. Groups were similar in signalment and procedures performed. No significant difference was found in overall, minor, and major complication rates between Group U and Group B, nor in the short and long-term function of surgical limbs. Nine out of 21 dogs developed clinical signs on the contralateral stifle in Group U, of which only three underwent corrective surgery.Clinical significance: Single-session bilateral surgery could be offered for dogs with bilateral MPL with complication rates and function of operated limbs similar to unilateral surgery.

Abstract
SummaryObjective To evaluate the outcome of surgical site infection (SSI) associated with tibial plateau levelling osteotomy (TPLO) implants following treatment by medical management alone or implant removal with or without the administration of antibiotic medication.Animals Ninety dogs (104 TPLO surgical procedures).Methods Records of dogs that had undergone TPLO implant removal due to SSI were reviewed. Outcome following treatment with antibiotic medications without implant removal, and treatment with implant removal with and without the administration of antibiotic medications was evaluated.Results Treatment of SSI with antibiotic medication alone failed in 88.9% (64/72) of the dogs. The clinical signs of SSI resolved in 94.9% (74/78) of the dogs treated with implant removal (with and without the administration of antibiotic medication postimplant removal). The effect of administration of antibiotic medication on outcome of treatment of the SSI by implant removal was not significant. The rate of SSI associated with the Synthes implant was higher than with the Slocum implant, but not the New Generation implant.Conclusion Implant removal with or without the administration of antibiotic medication post-implant removal for treatment of TPLO SSI provided superior outcome compared to treatment with antibiotic medications without implant removal.Clinical significance Implant removal should be considered for TPLO SSI that have not responded to appropriate medical management. Further investigation of the various TPLO implants and their effects on postoperative infection rate is warranted.

Abstract
SummaryObjective: To retrospectively review and describe the incidence of complications associated with tibial tuberosity advancement (TTA) surgical procedures in a group of Boxer dogs (n = 36 stifles) and compare the data with a non-Boxer control population (n = 271 stifles).Methods: Retrospective analysis of medical records to identify all dogs that underwent TTA surgery due to cranial cruciate ligament disease. These records were categorized into two groups: Boxer dogs and non-Boxer dogs (controls – all other breeds).Results: Of the 307 stifles included, 69 complications were reported in 58 joints. The complication rate differed significantly for Boxer dogs (16/36 stifles) and non-Boxer dogs (42/271 stifles), corresponding to an odds ratio of 5.8 (confidence interval: 1.96–17.02; p-value <0.001). Boxer dogs were more likely to undergo revision surgery and to develop multiple complications. The incidence of tibial tuberosity fractures requiring surgical repair (2/36 versus 1/271) and incisional infections requiring antibiotic treatment (three in each group) was significantly higher in the Boxer group.Clinical significance: Boxer dogs had more major and multiple complications after TTA surgery than the control non-Boxer group; these complications included higher rates of revision surgery, tibial tuberosity fractures requiring stabilization, and infection related complications. The pertinence and value of breed-specific recommendations for cranial cruciate ligament disease appears to be a subject worthy of further investigation.

Abstract
SummaryObjective: To compare the resulting complications, short-term results, and client satisfaction for treatment of cranial cruciate ligament rupture using either unilateral or bilateral single-session tibial tuberosity advancement (TTA) in dogs.Methods: Medical records of 68 dogs (101 stifles) undergoing unilateral or bilateral single-session TTA were evaluated. Data gathered included signalment, history, physical examination findings, anaesthesia and surgical time, type of cranial cruciate ligament rupture and meniscal injury, implants, and intra-operative and postoperative complications. A mixed effect logistic regression analysis was performed to determine if complications were grouped by surgical procedure. Linear regression was performed to determine the influence of the variables on the occurrence of complications. Values of p <0.05 were considered significant.Results: No major intra-operative complications occurred. Twenty stifles (20%) developed a complication after surgery (11 minor, 9 major). There was no significant difference in occurrence of complications between dogs undergoing unilateral (n = 8) or bilateral single-session (n = 12) TTA (p = 0.69). The only risk factor found to be associated with complication occurrence was age.Clinical significance: This is the first report evaluating the use of bilateral simultaneous TTA. There was no significant difference in complication rates between unilateral and bilateral single-session TTA. Additional evaluation is needed to fully determine the extent of complications and long-term outcome of bilateral single-session TTA.

Abstract
SummaryThe tibial plateau levelling osteotomy (TPLO) is one of the most common surgical procedures used to treat cranial cruciate ligament disease in dogs. Complications occurring during or after TPLO can range in severity from swelling and bruising to fracture and osteomyelitis. Ten to 34% of TPLO surgical procedures are reported to experience a complication and approximately two to four percent require revision surgery to address a complication. Although the risk factors for many complications have not been fully assessed, the best available evidence suggests that complications of TPLO can be reduced with increased surgeon experience, careful surgical planning, and accurate execution of the surgical procedure. Identification of known or suspected risk factors and intraoperative technical errors allow subsequent action to be taken that is aimed at decreasing postoperative morbidity. There is a need for prospective studies with consistent data reporting in order to fully reveal the incidence risk factors for complications associated with TPLO.

Abstract
SummaryObjective: To determine the rate of subsequent ‘pivot shift’, meniscal tear and risk factors associated with complications of tibial plateau levelling osteotomy (TPLO) and to assess clinical and owner perception outcome.Study design: Retrospective study.Sample population: Three hundred and forty-eight dogs that had undergone TPLO surgical procedures (n = 476 stifles).Methods: Medical records were reviewed for the retrieval of information on breed, sex, age, body weight, clinical history, radiograph findings, pre- and postoperative tibial plateau angle, limb alignment, unilateral versus bilateral disease, condition of cranial cruciate ligament (CCL) and menisci, implant material, healing time and complications. Clinical and owner-assessed questionnaire outcomes were also recorded.Results: Forty-six (9.7%) postoperative complications were reported. Twenty (4.2%) were classified as major complications requiring an additional surgical intervention, and 26 (5.5%) as minor complications. No risk factors associated with postoperative complications were identified. Ten (2.1%) subsequent meniscal injuries in the stifles with normal unaltered menisci at time of TPLO were reported with a median postoperative time of 9.5 months. Signs of postoperative ‘pivot shift’ were reported in 15 (3.1%) stifles. All stifles with a ‘pivot shift’ had a complete CCL rupture or a debrided partial CCL rupture a medial menisectomy was identified as a risk factor for a ‘pivot shift’ (p = 0.02). Dogs with intact medial meniscus had a significantly higher activity level (p <0.0001) and a shorter time to peak function (p = 0.02) than dogs that underwent menisectomy according to an owner questionnaire.Conclusions: Dogs with TPLO and intact meniscus seemed to have a better and faster recovery than dogs with TPLO and menisectomy based on owner questionnaires. ‘Pivot shift’ was infrequent after TPLO surgery. All dogs with a ‘pivot shift’ had a complete CCL rupture or a debrided partial CCL rupture and menisectomy was identified as a risk factor for its occurrence.Clinical relevance: Considering the relatively low rate of subsequent meniscal injury after TPLO, systematic medial meniscal release with TPLO may be unnecessary. The ‘pivot shift’ deserved further investigation to completely understand its mechanism, to identify its anatomic components and potential consequences on the stifle joint.

Abstract
SummaryObjectives: This study set out to compare the outcomes of tibial tuberosity advancement (TTA) and tibial plateau levelling osteotomy (TPLO) procedures in the treatment of dogs affected with unilateral cranial cruciate ligament disease (CCLD) based on subjective parameters and objective pressure platform analysis (baropodometry).Methods: Twenty-seven adult dogs weighing over 20 kg that were presented with unilateral CCLD and were treated by the TTA (12 dogs) or TPLO (15 dogs) surgical procedure. Patient allocation to either group was based on tibial plateau angle (TPA), according to clinical guidelines (indication for TTA for dogs was a TPA up to 25°, and indication for TPLO was any TPA). Pressure platform analysis was performed prior to surgery and at four different postoperative time points (14, 30, 60 and 90 days).Results: Limb function significantly improved following TTA and TPLO, with no significant differences between groups.Conclusion: The TTA and TPLO surgical procedures were considered to be equally effective in promoting weight bearing capacity recovery in dogs affected with unilateral CCLD under the conditions of this trial.

Abstract
SummaryObjective: To evaluate a cohort of dogs undergoing tibial plateau levelling osteotomy (TPLO) implant removal to determine key clinical features, prevalence, and indications for implant removal.Methods: Medical records of dogs undergoing TPLO implant removal at a private referral practice (Dallas Veterinary Surgical Center) between 2004–2008 were reviewed. Patient signalment, implant type, presence of concurrent medical disease, surgeon, antibiotic use, aerobic bacterial culture result, and operative findings were recorded. Data were analyzed using paired t-test, Fisher’s exact test, and Wilcoxon-rank sum test. Statistical significance was set at p <0.05.Results: The TPLO implants were removed from 126 dogs (n = 129, 4.8% of TPLO procedures) during the study period. Average time interval from TPLO to implant removal was 16.0 ± 17.8 months. The most common clinical signs were the presence of an open wound (n = 80), draining tract (n = 64), and lameness (n = 59). Culture of tissue or fluid from the implant bed or implants was positive for bacterial growth in 95/115 cases. A significantly greater proportion of the implants removed were Slocum TPLO plates (n = 109 6.1%) when compared to other TPLO plate types (n = 20 2.3%) (p <0.0001). No association was identified between a positive bacterial culture and measured variables.Clinical significance: Local bacterial infection and clinical signs of inflammation were the most common reasons for TPLO implant removal. There may be an increased implant-associated complication rate for Slocum TPLO plates in the study population.
