Prosthetic infection is one of the severe postoperative complications of arthroplasty. Mixed bacterial-fungal prosthetic infection is rare but can be disastrous. This case was a 76-year-old female suffered from prosthetic infection following total hip replacement due to femoral neck fracture and underwent multiple debridements. The culture of periprosthetic tissue was bacteriologically sterile following the first debridement, while the Staphylococcus hominis was identified in the second debridement in the previous hospitalization where fungal infection had not been considered. Thus the pathogen spectrum of anti-infection therapy failed to contain fungus. Ultimately, the culture result of our sampled periprosthetic tissue during the third debridement was Candida albicans without bacterium in our hospital. The fungal prosthetic infection was successfully treated by a two-stage revision with antifungal drugs. Accurate diagnosis and standardized treatment is the key to the therapy of infection after hip arthroplasty, especially for mixed bacterial-fungal prosthetic infection.

Periprosthetic joint infection (PJI) is the most difficult complication following total joint arthroplasty. Most of the etiological strains, accounting for over 98% of PJI, are bacterial species, with Staphylococcusaureus and Coagulase-negative staphylococci present in between 50% and 60% of all PJIs. Fungi, though rare, can also cause PJI in 1%-2% of cases and can be challenging to manage. The management of this uncommon but complex condition is challenging due to the absence of a consistent algorithm. Diagnosis of fungal PJI is difficult as isolation of the organisms by traditional culture may take a long time, and some of the culture-negative PJI can be caused by fungal organisms. In recent years, the introduction of next-generation sequencing has provided opportunity for isolation of the infective organisms in culture-negative PJI cases. The suggested treatment is based on consensus and includes operative and non-operative measures. Two-stage revision surgery is the most reliable surgical option for chronic PJI caused by fungi. Pharmacological therapy with antifungal agents is required for a long period of time with antibiotics and included to cover superinfections with bacterial species. The aim of this review article is to report the most up-to-date information on the diagnosis and treatment of fungal PJI with the intention of providing clear guidance to clinicians, researchers and surgeons.

PURPOSE: Antibiotic-loaded bone cement (ALBC) was usually used to prevent periprosthetic joint infection (PJI) in primary total knee arthroplasty (PTKA), but whether to use ALBC or plain bone cement in PTKA remains unclear. We aimed to compare the occurrence rate of PJI using two different cements, and to investigate the efficacy of different antibiotic types and doses administered in preventing surgical site infection (SSI) with ALBC. METHODS: The availability of ALBC for preventing PJI was evaluated by using a systematic review and meta-analysis referring to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Existing articles until December 2021 involving PTKA patients with both ALBC and plain bone cement cohorts were scanned by searching "total knee arthroplasty", "antibiotic-loaded cement", "antibiotic prophylaxis", "antibiotic-impregnated cement" and "antibiotic-laden cement" in the database of PubMed/MEDLINE, Embase, Web of Science and the Cochrane Library. Subgroup analysis included the effectiveness of different antibiotic types and doses in preventing SSI with ALBC. The modified Jadad scale was employed to score the qualities of included articles. RESULTS: Eleven quantitative studies were enrolled, including 34,159 knees undergoing PTKA. The meta-analysis results demonstrated that the use of prophylactic ALBC could significantly reduce the prevalence of deep incisional SSI after PTKA, whereas there was no significant reduction in the rate of superficial incisional SSI. Moreover, gentamicin-loaded cement was effective in preventing deep incisional SSI, and the use of high-dose ALBC significantly reduced the rate of deep incisional SSI after PTKA. Besides, no significant adverse reactions and complications were stated during the use of ALBC in PTKA. CONCLUSION The preventive application of ALBC during PTKA could reduce the rates of deep PJI. Furthermore, bone cement containing gentamicin and high-dose ALBC could even better prevent deep infection after PTKA. However, the existing related articles are mostly single-center and retrospective studies, and further high-quality ones are needed for confirmation.

Prosthetic joint infection is one of the most serious complications after artificial joint replacement.Accurate diagnosis and proper standardized treatment are the keys to improve the cure rate of prosthetic joint infection,reduce the rate of recurrence and disability,and restore limb function.Regarding the diagnosis and treatment of prosthetic joint infection,although relevant research has progressed rapidly in recent years,there are still many problems that have not been well understood and explained,and there are still big differences and controversies in many aspects.This has brought a lot of confusion to clinicians during their daily practice.In order to make the diagnosis and treatment of prosthetic joint infection in China more standardized,a group of domestic experts in related fields was organized by the Joint Surgery Committee of the Chinese Orthopaedic Association to search the literature and integrate expert opinions,and compiled the "Guidelines for the diagnosis and treatment of prosthetic joint infection".Those most important and clinically concerned issues are elaborated,including the diagnostic criteria, standardized diagnostic algorithm,proper application of important tests,treatment principles,and the correct selection of various treatment options.Targeted and actionable recommendations are proposed.This guideline is expected to provide references for domestic colleagues in the diagnosis and treatment of prosthetic joint infection.

Bone cement, consisting of polymethyl methacrylate, is a bioinert material used for prothesis fixation in joint arthroplasty. To treat orthopedic infections, such as periprosthetic joint infection, antibiotic-loaded bone cement (ALBC) was introduced into clinical practice. Recent studies have revealed the limitations of the antibacterial effect of ALBC. Moreover, with the increase in high infection risk patients and highly resistant microbes, more researches and modification of ALBC are required. This paper reviewed latest findings about ALBC for most popular and destructive pathogens, summarized the influence of antibiotic kind, drug dosage, application method, and environment towards characteristic of ALBC. Subsequently, new cement additives and clinical applications of ALBC in joint arthroplasty were also discussed.

OBJECTIVE: To investigate the therapeutic effects of vacuum sealing drainage (VSD) combined with antibiotics in treating acute periprosthetic joint infection (PJI). METHODS: From March 2012 to December 2018, there were 11 patients with acute PJI underwent debridement, VSD, antibiotics and retention of implant, including 7 males and 4 females, with an average age of 72.5 years old (ranged, 58 to 88 years old). There were 8 hips and 3 knees. Three patients had sinus tract. RESULTS: There were 2 patients with negative culture result and 9 patients with positive culture result, including 5 cases of methicillin sensitive staphylococcus aureus, 2 cases of methicillin-resistant staphylococcus aureus (MRSA), 2 cases of staphylococcus epidermidis. The mean follow up duration was 28 months (ranged from 8 to 52 months). One case of infection around hip prosthesis failed to be debrided. The time of debridement and replacement of the calcar joint was 84 days. Debridement was successful in 10 cases. At the latest follow up, Harris score of patients with successful debridement of hip periprosthetic infection ranged from 74 to 93, with an average score of 84.1;Knee Society scores of patients with periprosthetic infection were 84, 84, 89. CONCLUSION For acute infection around the prosthesis within 1 month after knee replacement and 6 weeks after hip replacement, and for bleeding around the prosthesis with acute infection caused by anticoagulant drugs, satisfactory results can be obtained by debridement, VSD and sensitive antibiotics.

Inflatable penile prostheses are an important tool in the treatment of medically refractory erectile dysfunction. One of the major complications associated with these prostheses is infections, which ultimately require device explanation and placement of a new device. Over the past several decades, significant work has been done to reduce infection rates and optimize treatment strategies to reduce patient morbidity. This article reviews the current state of knowledge surrounding penile prosthesis infections, with attention to the evidence for methods to prevent infection and best practices for device reimplantation.

The use of artificial urinary sphincter (AUS) for the treatment of stress urinary incontinence has become more prevalent, especially in the "prostate-specific antigen (PSA)-era", when more patients are treated for localized prostate cancer. The first widely accepted device was the AMS 800, but since then, other devices have also entered the market. While efficacy has increased with improvements in technology and technique, and patient satisfaction is high, AUS implantation still has inherent risks and complications of any implant surgery, in addition to the unique challenges of urethral complications that may be associated with the cuff. Furthermore, the unique nature of the AUS, with a control pump, reservoir, balloon cuff, and connecting tubing, means that mechanical complications can also arise from these individual parts. This article aims to present and summarize the current literature on the management of complications of AUS, especially urethral atrophy. We conducted a literature search on PubMed from January 1990 to December 2018 on AUS complications and their management. We review the various potential complications and their management. AUS complications are either mechanical or nonmechanical complications. Mechanical complications usually involve malfunction of the AUS. Nonmechanical complications include infection, urethral atrophy, cuff erosion, and stricture. Challenges exist especially in the management of urethral atrophy, with both tandem implants, transcorporal cuffs, and cuff downsizing all postulated as potential remedies. Although complications from AUS implants are not common, knowledge of the management of these issues are crucial to ensure care for patients with these implants. Further studies are needed to further evaluate these techniques.

Penile prosthesis implant (PPI) remains an effective and safe treatment option for men with erectile dysfunction (ED). However, PPI surgery can be associated with a higher risk of complications in certain populations. This article provides a critical review of relevant publications pertaining to PPI in men with diabetes, significant corporal fibrosis, spinal cord injury, concurrent continence surgery, and complex salvage cases. The discussion of each category of special populations includes a brief review of the surgical challenges and a practical action-based set of recommendations. While specific patient populations posed considerable challenges in PPI surgery, strict pre- and postoperative management coupled with safe surgical practice is a prerequisite to achieving excellent clinical outcomes and high patient satisfaction rate.
