Abstract:
Objective: To investigate the clinical effects of one-stage revision combined with intra-articular infusion of vancomycin in the treatment of chronic prosthetic joint infection (PJI) caused by Enterococcal. Methods: From May 2013 to June 2020,the clinical data of 9 patients (2 males and 7 females) with chronic Enterococcal PJI treated with one-stage revision using intra-articular infusion of vancomycin at Department of Orthopaedics,First Affiliated Hospital of Xinjiang Medical University were retrospectively analyzed,including 8 hips and 1 knee.A total of 9 patients with age of (63.9±11.7)years (range:43 to 76 years) were included, and the body mass index was (23.6±4.3)kg/m2 (range:18 to 30 kg/m2).There were 6 cases with antibiotic history and 5 cases with sinus tract.The joint fluid,infected tissue around the prosthesis and ultrasonic shock fluid of the prosthesis were collected during operation for microbial culture identification and drug sensitivity test.After thorough debridement of the infected site and removal of the infected prosthesis,a new prosthesis was implanted,then the drainage tube in the operation area was placed.After surgery,vancomycin(1.0 g,q12 h) was combined with intra-articular vancomycin(0.5 g,qd) in monomicrobial PJI,and vancomycin(1.0 g,q12 h) was combined with intra-articular vancomycin (0.5 g,qd) and imipenem/meropenem (0.5 g,qd),and the interval between the two drugs was 12 hours in polymicrobial PJI.Hip and knee functions were evaluated by Harris Hip Score or Knee Society Score(KSS),respectively.The comparison of hip function scores before and after operation was performed by paired t-test. Results: All patients were followed up for (60±39)months(range:24 to 110 months).Two cases were infected with Enterococcus faecium and 7 cases were infected with Enterococcus faecalis.There were 7 cases of monomicrobial infection and 2 cases of polymicrobial infection.Erythromycin(5/9),tetracycline(4/9),ciprofloxacin and β-lactam antibiotics(3/9) were the top three antibiotics in Enterococci resistance rate.The sensitive antibiotics for Enterococcal were vancomycin,linezolid and tigecycline.The average duration of intravenous antibiotics was (14±1)days (range:13 to 17 days),and the average duration of antibiotics in articular cavity was (15±2)days(range:11 to 20 days).Mean duration of oral antibiotic use after discharge was (2±1)months(range:1 to 3 months).One case of polymicrobial PJI treatment failed,with a failure rate of 1/9.At last follow-up,the Harris score of patients with hip PJI increased from (43±6)points to (84±6)points(t=-11.899, P<0.01). KSS score of knee function was improved from 33 point pre-operatively to 85 point post-operatively;overall function score was improved from 35 point pre-operatively to 80 point post-operatively.During the treatment,no formation of sinus tract of the hip joint caused by a catheter,skin necrosis at the knee puncture site or leakage of joint fluid;no complications such as deep vein thrombosis and pulmonary embolism occurred. Conclusions: One-stage revision combined with intra-articular infusion of vancomycin can achieve acceptable infection control rate and joint function in patients with chronic Enterococcus PJI.However,the treatment of polymicrobial PJI still needs to be further verified.
