Juvenile idiopathic arthritis is the leading cause of hip replacement in young children. However, arthroplasty in this population is challenging with several concerns about quality of the growing bone, young age for revision surgery, and difficulties in potential several revisions. In this study we introduce a case of a 12-year old who is one of the youngest patients to undergo revision hip arthroplasty. The index operation was done as a hybrid replacement, cemented for stem and press fit for acetabular component. Two years later revision was done with severe femoral deficiency. This second procedure was challenging but with short-term promising results. So we reviewed the literature for arthroplasty in this young population regarding recent findings and trends. According to the literature survival of the prosthesis is longer with a cemented acetabular component and press fit stem; however, there are evidences that show poor outcome of joint replacement after the first revision in juvenile idiopathic arthritis patients.

Rational: One of the important considerations to select the appropriate outcome measures is determining if the tool is relevant to patients. Despite the availability of various performance-based tests to objectively assess function, it is unknown which performance-based tests best capture important aspects of function after hip or knee arthroplasty.
Aims And Objectives: Our systematic review aimed to identify the existing performance-based tests used in hip or knee arthroplasty and link the activity component of each test to the modified International Classification of Functioning, Disability and Health (ICF) core set for osteoarthritis (OA).

Introduction: Patients undergoing total hip arthroplasty (THA) with preoperative anemia are at higher risk for transfusion. Blood-conserving interventions can reduce perioperative transfusions. This retrospective study evaluates the efficacy and safety of a patient blood management (PBM) protocol in elective primary THA patients with preoperative anemia.

Background/objectives: Bone marrow adipose tissue (BMAT) has been described as an important biomechanic and lipotoxic factor with negative impacts on skeletal and hematopoietic system regeneration. BMAT undergoes metabolic and cellular adaptations with age and disease, being a source of potential biomarkers. However, there is no evidence on the lipid profile and cellularity at different skeletal locations in osteoarthritis patients undergoing primary hip arthroplasty.

Total hip arthroplasty (THA) is a widely performed surgical procedure that has evolved significantly due to advancements in artificial intelligence (AI) and robotics. As demand for THA grows, reliable tools are essential to enhance diagnosis, preoperative planning, surgical precision, and postoperative rehabilitation. AI applications in orthopedic surgery offer innovative solutions, including automated hip osteoarthritis (OA) diagnosis, precise implant positioning, and personalized risk stratification, thereby improving patient outcomes.

It is characterized by a triad of homogentisic aciduria, bluish-black discoloration of connective tissues (ochronosis) and arthropathy of large weight bearing joints. We report on a middle-aged female patient with bilateral severe ochronotic arthritis of both hips and shoulder joints requiring total joint replacements as staged procedures which were done without complications offering a complete pain relief and a satisfactory clinical and functional outcome.
