Objective: This study aimed to determine which pedagogic method, online workshops or live medical education, was the better way to teach about self-medication for middle school students.

Methods: The following groups were formed: group O (students receiving online education), group L (students participating in live medical education animated by a medical practitioner and a science teacher) and group C (students without any medical learning). To compare them, the students answered three multiple choice questions before and after the educational intervention.

Purpose: The dual mobility cup (DMC) reduces the dislocation rates in total hip arthroplasty (THA). DMC systems include anatomical (non-modular or monoblock) (ADM) and modular dual mobility (MDM) components (Stryker Orthopaedics, Mahwah, NJ, USA). This review aims to assess differences between these two types of DMC implants concerning dislocation and revision rates, as well as patient-reported outcomes.

Article Synopsis
  • Finite element analysis (FEA) is crucial in orthopaedics for simulating and analyzing surgical procedures, revealing that removing over 20% of the meniscus significantly raises shear stress in cartilage and heightens knee joint degeneration risk.
  • Meniscal root repair can enhance meniscal biomechanics and lower osteoarthritis risk, even with non-ideal repairs, while FEA helps to study the biomechanics of knee ligaments, showing that certain graft techniques closely mimic native knee function.
  • Incorporating lateral augmentation techniques can enhance stability in ACL and PCL repairs, and there is a need for future studies to integrate patient-specific anatomical and mechanical data for better experimental models.

Background: Reverse shoulder arthroplasty (RSA) is popular for the treatment of degenerative glenohumeral joint disease. Bone remodeling around the humeral stem related to stress shielding (SS) has been described. This review focuses on the specific radiological characteristics, risk factors, and clinical consequences of SS in RSA.

Antibiotic-loaded cement spacers (ALCSs) are essential for treating periprosthetic joint infections (PJIs) by providing mechanical support and local antibiotic delivery. The purpose of this review is to comprehensively examine the various types of spacers utilised in the management of periprosthetic joint infections (PJIs), including both static and articulating variants and to analyse the fundamental principles underlying spacer use, their clinical benefits, the selection and administration of antimicrobial agents, appropriate dosages, and potential adverse effects. Articulating spacers, which allow joint mobility, often yield better outcomes than static ones.

Article Synopsis
  • The study examined the practices of Greek surgeons regarding patellar management in total knee arthroplasty (TKA) and assessed the outcomes and rates of secondary resurfacing.
  • A systematic review of six clinical studies, including 1,084 TKAs, found that only 0.6% involved patellar resurfacing and that non-resurfacing procedures led to good functional outcomes with a revision rate of 7.6%.
  • The findings suggest that Greek surgeons favor non-resurfacing of the patella, resulting in favorable outcomes and relatively low necessity for further procedures, indicating a fair methodological quality of the studies reviewed.

To assess the immediate and six-month follow-up effects of medical education simultaneously provided by a practitioner and a science teacher on middle school students regarding self-medication and knowledge of the healthcare system. Two groups were constituted: the learning group (L group), with students receiving an interactive medical education, and the control group (C group), which included students without medical education. Both groups were evaluated by using a six-multiple choice question (MCQ) evaluation form: three times for L group - just before the medical workshop (T0), immediately after the medical workshop (T1) and at six-month follow-up after the medical workshop (T2) - and only the evaluation at T0 for students in C group.

Introduction: This systematic review aims to critically assess the literature comparative studies investigating collared and collarless Corail stem in primary total hip arthroplasty (THA) to find differences in revision rates, radiographic and clinical outcomes, and postoperative complications between these two types of the same stem.

Methods: Eligible studies were found by searching PubMed, Science Direct/Scopus, and the Cochrane Database of Systematic Reviews from conception till May 2023. The PRISMA guidelines were followed.

Introduction: There have been controversial studies on the impact of prior knee arthroscopy (KA) on outcomes of total knee arthroplasty (TKA). The purpose of this comparative study is to investigate the impact of prior KA of medial meniscus on patients undergoing TKA by evaluating the International Knee Society Score (IKS), the complications, and revisions.

Methods: This retrospective study reviewed 84 patients with TKA who had undergone prior KA of the medial meniscus and compared them to 84 cases, without a history of prior KA as a control group.

Septic non-union in long-bone fractures represents a challenging clinical entity. Management of lower extremity segmental bone defects, aiming to restore functional anatomy, remains extremely difficult and controversial. Masquelet technique is a reconstruction method for large diaphyseal bone defects, based on the notion of the induced membrane.

  • Slipped capital femoral epiphysis (SCFE) is a common hip disorder in teens, and this study examines how age, slip severity, and stability affect recovery and physical activity post-surgery.
  • The researchers analyzed historical patient data from 2010 to 2015, comparing outcomes for two surgical methods: pining in situ (PIS) and the modified Dunn (MD) procedure.
  • Their findings showed that factors like age and slip severity did not significantly impact patients' ability to return to physical activity, but older patients tended to have worse hip scores, highlighting the need for further investigation into other influencing factors.

Prosthetic joint infections (PJIs) caused by fungi, although relatively rare, represent a major surgery-related complication. An extremely rare fungal PJI, following revised total knee replacement (TKR) caused by , is reported, and a meticulous review of similar cases is provided. A 74-year-old female, who underwent primary total knee arthroplasty 10 years ago and a revision surgery three weeks ago, presented with signs and symptoms of PJI.

Fungal hip prosthetic joint infections (PJIs) are rare but severe infections. Their incidence has increased in the last decades due to the aging population, as well as due to the increased number of immunosuppressed hosts. The present review of all published fungal PJIs in hip arthroplasties aims to present as much data as possible for both medical and surgical treatment options, so that the best applicable management may be concluded.
