Postoperative analgesic efficacy of peripheral levobupivacaine and ropivacaine: a prospective, randomized double-blind trial in patients after total …
2008
BACKGROUND: Several previous trials have characterized the intra- and postoperative effects of the recently introduced local anesthetics, levobupivacaine and ropivacaine, for a variety of continuous peripheral nerve blocks. METHODS: We compared the analgesic efficacy of levobupivacaine 0.125% versus ropivacaine 0.2% via patient-controlled femoral nerve analgesia after total knee arthroplasty. In a double-blind, randomized, prospective design, 60 patients received femoral infusion with either substance. We analyzed postoperative local anesthetic consumption, pain scores, motor block, and opioid requirements over 72 h. RESULTS: Pain scores, motor block incidence, and opioid requirements were …
Effect of total knee replacement surgery and postoperative 12 month home exercise program on gait parameters
2017
Abstract Objective To evaluate the effects of surgery and a postoperative progressive home exercise program on gait parameters among individuals operated with total knee arthroplasty. Design Single blinded randomized controlled trial. Subjects 108 patients (84 females, 24 males, mean age 69 years). Interventions Patients were equally randomized into an exercise group (EG) and control group (CG). The 12-months progressive home exercise program starting two months postoperatively was compared to usual care. Methods Gait analysis was performed using the Gaitrite electronic walkway system. In addition, knee extension and flexion strength were measured by a dynamometer preoperatively, and pain o…
Continuous Femoral Catheter for Postoperative Analgesia After Total Knee Arthroplasty
2020
Introduction Postoperative pain management in the total knee replacement (TKR) represent a fundamental step for a positive outcome, allowing rapid mobilization, already on the first day. Further, continuous peripheral nerve block techniques have been reported to allow effective and safe control of acute postoperative pain, ensuring the implementation and completion of an accurate and intensive joint rehabilitation program. Aim The aim of this study was to assess early mobility and compliance of patients that underwent TKR surgery using the femoral block. Methods For the study, all patients that underwent TKR from 2015 to 2018 with ASA score between II-III was evaluated. Patients underwent v…
Expectativas del paciente ante la artroplastia total de rodilla.
2020
espanolIntroduccion: La artroplastia total de rodilla es una de las cirugias mas realizadas en ortopedia y su incidencia esta en aumento, siendo la indicacion principal en patologias como la artrosis y la artritis reumatoide cuando estas no responden al tratamiento conservador. Ademas, en los ultimos anos esta tomando especial relevancia la opinion y satisfaccion de los pacientes respecto a la intervencion, siendo estos parte esencial en el proceso asistencial. Material y metodos: En el presente trabajo se ha realizado un estudio con 30 pacientes intervenidos de artroplastia total de rodilla. Estos han respondido a dos encuestas, una de ellas acerca de la importancia que otorgaban a distint…
Medidas de Tromboprofilaxis en Artroplastia Total de Rodilla. Práctica habitual en la Comunidad Valenciana y revisión bibliográfica.

espanolAntecedentes: El tromboembolismo es una complicacion de la cirugia de artroplastia total de rodilla. Para su prevencion disponemos de multiples medidas fisicas y farmacologicas.Objetivo:Conocer quemedidas de prevencion tromboembolica son las empleadas por los cirujanos ortopedicos en cirugia protesica de rodilla primaria en diferentes centros hospitalarios de nuestra region.Metodo: Estudio transversal descriptivo observacional basado en encuesta dirigida a especialistas COT de 9 hospitales publicos de la Comunidad Valenciana y busqueda bibliografica.Resultados: Se obtuvieron 64 encuestas. Todos los cirujanos eligen HBPM durante un mes como medida de tromboprofilaxis, descartando anti…
Inestabilidad de la articulación tibio-peronea proximal como causa de dolor en artroplastia total de rodilla primaria.
2020
espanolLa inestabilidad de la articulacion tibio-peroneaproximal (ATPP) aislada como causa de dolor en una rodilla protetizada es una entidad clinica muy poco frecuente, hasta la fecha solo hemos encontrado una referencia en la bibliografia de inestabilidad ATPP asociada a Artroplastia total de rodilla. Revisamos la bibliografia sobre las diferentes formas de inestabilidad y su etiologia, asi como las posibilidades de tratamiento conservador y quirurgico. Presentamos el caso de un paciente con inestabilidad ATPP anterolateral asociada a una ATR primaria posteroestabilizada (PS) con platillo tibial movil.

STRUCTURAL ANALYSIS OF A POSTERIOR STABILITY TOTAL KNEE JOINT REPLACEMENT
2011
Aim of this work is to compare two different total knee prostheses that differ in the shape of the Polyethylene (PE) insert, trying to optimize the shape of the best one, in order to reduce the stress peaks. The study procedure has been divided into the following steps. First step has been the three-dimensional shape acquisition of the two prostheses by means of a COMET5 3D scanner. The morphology of two prototypes of the prostheses has been acquired by elaborating multiple Moirè fringe pattern projected on their surfaces. Second step consisted of the manipulation of these data in a CAD module, that is the interpolation of raw data into parametric surfaces, reducing singularities due to the…
The Patellofemoral Arthroplasty: The Great Solution, the Great Problem
2012
Unfortunately, many orthopedic surgeons believe that the definite solution for eliminating anterior knee pain in a young patient with multiple operations is the patellofemoral prosthesis (“The Great Solution”). But, they fail to ask themselves the most important question; what is causing the pain? When a patellofemoral prosthesis is implanted in these young patients without finding out the cause of the pain, a more serious problem could be created with a worse solution (“The Great Problem”). The cases we present spotlight this abuse.
Assessment of paradoxical anterior translation in a CR total knee prosthesis coupling dynamic RSA and FE techniques
2021
Purpose: The study aims were to assess the kinematic data, Internal-External (IE) rotation, and Antero-Posterior (AP) translation of the contact points between the femoral condyles and polyethylene insert and to develop a combined dynamic RSA-FE (Radiostereometric – Finite Element) model that gives results congruent with the literature. Methods: A cohort of 15 patients who underwent cemented cruciate-retaining highly congruent mobile-bearing total knee arthroplasty were analyzed during a sit-to-stand motor task. The kinematical data from Dynamic RSA were used as input for a patient-specific FE model to calculate condylar contact points between the femoral component and polyethylene insert. …
Effects of Adding Motor Imagery to Early Physical Therapy in Patients with Knee Osteoarthritis who Had Received Total Knee Arthroplasty
2020
Abstract Objective To investigate the effects of the inclusion of motor imagery (MI) principles into early physical therapy on pain, disability, pressure pain thresholds (PPTs), and range of motion in the early postsurgical phase after total knee arthroplasty (TKA). Methods A randomized clinical trial including patients with knee osteoarthritis who have received TKA was conducted. Participants were randomized to receive five treatment sessions of either physical therapy with or without MI principles in an early postsurgical phase after a TKA (five days after surgery). Pain intensity (visual analog scale [VAS], 0–100), pain-related disability (short-form Western Ontario McMaster Universities…
