Introduction: The National Orthopaedics Examination (EMNOT) was initially designed for Chilean orthopaedic program graduates and is now a crucial component of the revalidation process for international orthopaedic surgeons seeking practice in Chile. This study aims to describe participation and performance of EMNOT examinees based on their origin and to analyze the difficulty and discrimination indexes during its first 11 years of implementation.
Methods: A retrospective assessment was conducted on all EMNOT results from 2009 to 2019.
Background: An aging population with a resultant higher incidence of osteoarthritis have increased the need for total hip (THA) and knee arthroplasty (TKA) worldwide. The purpose of this study was to explore what medical and social risk factors are considered relevant by Chilean orthopaedic surgeons in decisions regarding indications for THA or TKA.
Methods: An anonymous survey was sent to 165 hip and knee arthroplasty surgeons who were members of the Chilean Orthopedics and Traumatology Society.
Introduction: Acute patellar tendon ruptures are frequently observed in patients with metabolic comorbidities, and the benchmark treatment is surgical repair. It is desirable not to harm an already fragile biologic environment with sutures and hardware. We aimed to compare the mechanical requirements of an isolated, flexible, high-strength nonabsorbable transosseous suture frame with that of the Krackow suture technique.

- The study investigates the short-term and long-term effects of medial opening wedge high tibial osteotomy (MOW-HTO) on patients with medial knee joint osteoarthritis, focusing on functional outcomes and complications over a decade.
- A total of 55 patients, predominantly male, were reviewed, revealing significant improvements in functional scores (IKDC and Lysholm) one year post-surgery, with only minor complications observed and no need for major revision surgeries.
- The findings suggest that younger patients (under 40 years old) who undergo surgery tend to achieve better functional outcomes compared to older patients, emphasizing the importance of timing in the surgical intervention.
Knee osteoarthritis (OA) is a leading cause of pain and disability. Although conventional treatments show modest benefits, pilot and phase I/II trials with bone marrow (BM) and adipose-derived (AD) mesenchymal stromal cells (MSCs) point to the feasibility, safety, and occurrence of clinical and structural improvement in focal or diffuse disease. This study aimed to assess the safety and efficacy of the intra-articular injection of single or repeated umbilical cord-derived (UC) MSCs in knee OA.
