Purpose: Knee arthroplasty is an effective treatment for severe knee degeneration; however, periprosthetic joint infection (PJI) is one of its serious complications. Single- and two-stage revision are common treatments, but few studies have compared single- and two-stage revision for PJI after knee arthroplasty. This study aimed to compare the reinfection and reoperation rates of single- and two-stage revision through meta-analysis.

Methods: The review process was conducted according to the PRISMA guidelines. We searched the PubMed, Medline, Embase and Cochrane Central Register of Controlled Trials databases for trials comparing single- and two-stage revision for PJI after knee arthroplasty from the respective inception dates to April 2023. Two researchers individually screened the studies, performed the literature quality evaluation and data extraction and used Stata 17 software for data analysis.

Results: The meta-analysis showed that the reinfection rate was significantly lower in the single-stage revision group than in the two-stage revision group. While the reoperation rates demonstrated no statistically significant difference between the two groups. We presented descriptive results because the discrepancies in the knee function scores and data reported in the studies meant that these data could not be combined in the meta-analysis.

Conclusion: Based on the available research, single-stage revision is a reliable option for PJI after knee arthroplasty. However, when developing the best treatment strategy, it is still necessary to consider the individual circumstances and needs of the patient, as well as the risks of postoperative rehabilitation and complications.

Purpose: For many decades, patients recovering from wound closure have been instructed not to bathe. Although studies have shown that earlier postoperative bathing does not increase the risk of wound infection, it remains rare in practice for patients to be allowed earlier postoperative bathing. We performed this meta-analysis to determine how earlier bathing affected rates of wound infection, other complications, and patient satisfaction.

Methods: This systematic review conforms to PRISMA guidelines. The PubMed, EMBASE, Medline, Web of Science, and the Cochrane Central Register of Controlled Trials were searched from their inception dates to December 31, 2022. We estimated pooled values for the efficacy of trial of earlier bathing versus delayed bathing using the odds ratio and their associated 95% CI, and we used the I 2 statistic to assess heterogeneity between studies contributing to these estimates.

Results: Of the 1813 articles identified by our search, 11 randomized controlled trials including 2964 patients were eligible for inclusion. The incidence of wound infection did not differ significantly between the earlier bathing and delayed bathing groups, nor did rates of other wound complications such as redness and swelling, or wound dehiscence. However, the incidence of hematoma in the delayed bathing group was higher than in the earlier bathing group. Reported patient satisfaction was significantly higher in the earlier bathing group.

Conclusion: The medical community, health authorities, and government should create and disseminate clinical practice guidelines to guide patients to evidence-based beneficial treatment.

Purpose: Primary bone tumors of the fibula are rare. Distal fibular resection has a significant impact on ankle biomechanics and gait, possibly leading to complications such as ankle instability, valgus deformity, and degenerative changes. Question: Is there a need for reconstructive surgery after distal fibular resection, and what reconstructive procedures are available?

Materials and methods: The review is registered with the PROSPERO International Register of Systematic Reviews. Inclusion criteria consisted of all levels of evidence, human studies, patients of all ages and genders, publication in English, and resection of the distal portion of the fibula due to tumor pathology. The reviewers defined four different categories of interest by method of treatment. Additional articles of interest during full-text review were also added.

Results: The initial search resulted with a total of 2958 records. After screening, a total of 50 articles were included in the study. Articles were divided into 'No reconstruction', 'Soft tissue reconstruction', 'Bone and soft tissue reconstruction', and 'Arthrodesis, arthroplasty or other reconstruction options' groups.

Conclusion: Limb salvage surgery should be followed by reconstruction in order to avoid complications. Soft tissue reconstructions should always be considered to stabilize the joint after fibular resection. Bone reconstruction with reversed vascularized fibula is the preferred technique in young patients and in cases of bone defects more than 3 cm, while arthrodesis should be considered in adult patients. Whenever possible for oncologic reason, if a residual peroneal malleolus could be preserved, we prefer augmentation with a sliding ipsilateral fibular graft.

Bosworth fracture (BF) is a special type of locked ankle fracture-dislocation, characterized by displacement of a fragment of the fractured fibula from the fibular notch behind the posterior surface of the distal tibia. BF is a complex injury affecting multiple structures of the ankle joint, which is still frequently misjudged even today, potentially leading to severe complications. CT examination, including 3D reconstructions, should be the diagnostic standard in BF, as it provides a complete picture of the fracture pathoanatomy, most prominently the morphology of the frequently associated posterior malleolar fracture. BF requires early reduction of the displaced fibular fragment without repeated attempts on closed reduction. Non-operative treatment of BF almost always fails. The standard treatment procedure is early open reduction internal fixation. Due to the relative severity and paucity of the injury, BF seems to be particularly prone to soft tissue complications, including compartment syndrome. The results of operative treatment are mixed. Many studies report persistent pain even after a short time interval, with limitations of the range of motion or even stiffness of the ankle joint, and development of degenerative changes. Larger studies with long-term results are still missing.

The use of artificial intelligence (AI) in medicine and surgery is currently predicted to be very promising. However, AI has the potential to change the doctor's role and the doctor-patient relationship. It has the potential to support people's desires for health, along with the potential to nudge or push people to behave in a certain way. To understand these potentials, we must see AI in the light of social developments that have brought about changes in how medicine's role, in a given society, is understood. The trends of 'privatisation of medicine' and 'public-healthisation of the private' are proposed as a contextual backdrop to explain why AI raises ethical concerns different from those previously caused by new medical technologies, and which therefore need to be addressed specifically for AI.

Long bone non-unions represent a serious clinical and socioeconomical problem due to the prolonged episodes, frequent sequelae, and variable treatment effectiveness. Bone grafts, classically involving the autologous iliac crest graft as the 'gold standard' bone graft, enhance bone regeneration and fracture healing incorporating osteoconductive and/or osteoinductive/osteogenic capacity to the non-union under treatment. Structural alternatives to autologous bone grafts include allografts and bone substitutes, expanding the available stock but loosing biological properties associated with cells in the graft. Biological alternatives to autologous bone grafts include bone marrow concentration from iliac crest aspiration, bone marrow aspiration from reaming of the diaphyseal medullary canal in the long bones, and isolated, expanded mesenchymal stem cells under investigation. When the combination with natural and synthetic bone substitutes allows for larger volumes of structural grafts, the enhancement of the biological regenerative properties through the incorporation of cells and their secretoma permits to foresee new bone grafting solutions and techniques.

The treatment of musculoskeletal infections (MSIs), including periprosthetic joint infection (PJI) and fracture-related infection (FRI), is often complicated by biofilm-related challenges necessitating multiple revision surgeries and incurring substantial costs. The emergence of antimicrobial resistance (AMR) adds to the complexity of the problem, leading to increased morbidity and healthcare expenses. There is an urgent need for novel antibacterial strategies, with the World Health Organization endorsing non-traditional approaches like bacteriophage (phage) therapy. Phage therapy, involving the targeted application of lytic potent phages, shows promise in the treatment of MSIs. Although historical clinical trials and recent case studies present significant milestones in the evolution of phage therapy over the past century, challenges persist, including variability in study designs, administration protocols and phage selection. Efforts to enhance treatment efficacy consist of personalized phage therapy and combination with antibiotics. Future perspectives entail addressing regulatory barriers, standardizing treatment protocols, and conducting high-quality clinical trials to establish phage therapy's efficacy for the treatment of MSIs. Initiatives like the PHAGEFORCE study and the PHAGEinLYON Clinic programme aim to streamline phage therapy, facilitating personalized treatment approaches and systematic data collection to advance its clinical utility in these challenging infections.

Acetabular revision arthroplasty, a demanding field of reconstructive hip surgery, calls for innovative strategies to deal with challenging bone defects and implant failure seen in revision cases. Conventional implant solutions might fall short of adequately addressing severe bone loss and ensuring stable fixation, highlighting the necessity of customized strategies. Personalized megaimplants, distinguished by their tailor-made design and large-scale construction, present a viable option to overcome these challenges. The present article provides an elaborate analysis of custom-made megaimplants in acetabular revision arthroplasty, shedding light on the underlying principles, design complexities, manufacturing methods, applications in the clinical setting, and outcome assessment. The aim of this review is to present a comprehensive insight into personalized megaimplants and their contribution to the advancement of orthopedic surgery.

This review explores the intricate relationship between knee osteotomy and frontal plane joint line orientation, emphasizing the dynamic nature of the joint line's influence on knee forces and kinematics. Consideration of coronal alignments, knee phenotypes, and associated angles (medial proximal tibial angle (MTPA), lateral distal femoral angle (LDFA), joint line convergence angle (JLCA)) becomes crucial in surgical planning to avoid joint line deformities. The double-level osteotomy is to be considered a valid option, especially for severe deformities; however, the target patient cannot be selected solely based on high predicted postoperative joint line obliquity (JLO) and MPTA.

Despite the common occurrence of radial head fractures, there is still a lack of consensus on which radial head fractures should be treated surgically. The radial head is an important secondary stabilizer in almost all directions. An insufficient radial head can lead to increased instability in varus-valgus and posterolateral rotatory directions, especially in a ligament-deficient elbow. The decision to perform surgery is often not dictated by the fracture pattern alone but also by the presence of associated injury. Comminution of the radial head and complete loss of cortical contact of at least one fracture fragment are associated with a high occurrence of associated injuries. Nondisplaced and minimally displaced radial head fractures can be treated non-operatively with early mobilization. Displacement (>2 mm) of fragments in radial head fractures without a mechanical block to pronation/supination is not a clear indication for surgery. Mechanical block to pronation/supination and comminution of the fracture are indications for surgery. The following paper reviews the current literature and provides state-of-the-art guidance on which radial head fractures should be treated surgically.
