Objectives The aim of this is to investigate the changes in body mass index (BMI) following knee arthroplasty and to evaluate their impact on patient-reported outcomes and functional evaluations. Methods This observational study included 90 patients who underwent total knee arthroplasty (TKA) and were followed up for a median period of 2.6 years. B...

Purpose: The purpose of this study was to assess patient satisfaction and identify risk factors for dissatisfaction after anterior stabilised conventional total knee arthroplasty (TKA) without patellar resurfacing, using the Goodman score. Methods: We conducted a cross-sectional study using data from our institutional database from 1 January 201...

Purpose: The aim of this study was to describe the incidence rate per 100,000 inhabitants (IR) of knee arthroscopic procedures and knee ligament reconstruction in Chile, between 2004 and 2019. Methods: Cross-sectional study. Patients who underwent a meniscal surgery and patients undergoing knee ligament reconstruction were identified in the databas...

Resumen Objetivo Describir el resultado funcional informado por el paciente de una cohorte de pacientes sometidos a artroplastia unicompartimental de rodilla (AUR) en un hospital universitario chileno. Métodos Se diseñó un estudio de cohorte histórica. Se incluyeron todos los pacientes que se sometieron a AUR de platillo fijo entre 2003 y 2019. Un...

The purpose of this study was to compare the efficacy of periarticular infiltration of gonyautoxin 2/3 (GTX 2/3) and a mixture of levobupivacaine, ketorolac, and epinephrine for pain management after total knee arthroplasty (TKA). Forty-eight patients were randomly allocated to receive periarticular infiltration of 40 µg GTX 2/3 (n = 24) diluted in...

Purpose To analyze the impact of the coronavirus disease 2019 (COVID-19) outbreak during the first pandemic year in a single country. Methods A cross-sectional study was designed. The free access database of the Chilean Department of Statistics and Health Information (DEIS) was used to compare the number of orthopedic procedures between 2019 and 2...

Rodilla es un libro que refleja el esfuerzo de casi treinta profesionales por ordenar y actualizar las materias más frecuentes que se ven en esta especialidad. Los treinta y tres capítulos distribuidos a lo largo de cuatrocientas páginas están dirigidos a todos aquellos que se interesen por los problemas clínicos de esta articulación, que en genera...

Objective Surgical techniques are learned gradually throughout an orthopedic residency. Training on real patients carries drawbacks such as limited access and elevated risk. Alternatively, surgical simulation allows residents to practice in a safe environment with greater access to standardized surgical tasks. Virtual reality simulators display ima...

Estudios radiológicos iniciales según segmento Interpretación y clasificación de las lesiones traumáticas en el contexto de atención primaria

To analyze the torsion of the lower extremities in a healthy cohort and to determine the contribution of different segments of the femur and tibia to the torsion of both bones. Methods: In this cross-sectional study, 32 patients with nonjoint or bone-related symptoms were analyzed by CT angiography. Lower-limb torsion, femoral torsion, proximal f...

This study aims to correlate the tibial tubercle to trochlear groove (TT-TG) distance with knee axial alignment. The hypothesis is that as internal torsion of the distal femur or external torsion of the proximal tibial increases, the TT-TG distance increases. We designed a cross-sectional study approved by our institutional ethics review board. We...

Keywords: ACL Graft Contamination; Graft Biomechanics; Maximum Tension Force; ACL Reconstruction Purpose: To compare the maximum tensile force (MTF) of Semitendinosus (ST) and Gracilis (G) after being rinsed with Chlorhexi-dine or Gentamicin. Abbreviations Methods: Experimental Study. Eight consecutive patients with anterior cruciate ligament (ACL)...

Purpose: To compare the maximum tensile force (MTF) of Semitendinosus (ST) and Gracilis (G) after being rinsed with Chlorhexi- dine or Gentamicin. Methods: Experimental Study. Eight consecutive patients with anterior cruciate ligament (ACL) injury and reconstructed with ST- G technique were recruited. After the tibial fixation, the excess graft was...

Objective To evaluate the effect of a single intraarticular dose of Gonyautoxins for pain control after Total Knee Arthroplasty (TKA). Subjects 30 consecutive patients with osteoarthritis with Kellgren & Lawrence level of two or more, who required TKA, were enrolled. Methods Subjects receive a single intra-articular infiltration of 40 µg dose of Go...

Anterior Cruciate Ligament (ACL) injury is an important cause of days lost in athletes. Most ACL injuries are non-contact and are associated with biomechanical risk factors that increase tension in the ACL: increased knee valgus (KV) and hip flexion (HF) and decreased flexion of knee (KF). Muscle around the knee contributes to knee stability, so fa...

Improvements in pain management techniques in the last decade have had a major impact on the practice of total knee arthroplasty (TKA). Gonyautoxin are phycotoxins, whose molecular mechanism of action is a reversible block of the voltage-gated sodium channels at the axonal level, impeding nerve impulse propagation. This study was designed to evalua...
