The purpose of this study was to determine the diagnostic accuracy of 3 T MRI, including sensitivity, specificity, negative and positive predictive values, for detection of posterior medial and lateral meniscus root tears and avulsions. All patients who had a 3 T MRI of the knee, followed by arthroscopic surgery, were included in this study. Arthroscopy was(More)
BACKGROUND Revision anterior cruciate ligament (ACL) reconstruction requires a precise evaluation of previous tunnel locations and diameters. Enlargement of the tunnels, despite not usually affecting primary reconstruction outcomes, plays an important role in revision ACL management. Three dimensional (3D) computed tomography (CT) models are reported to be(More)
BACKGROUND Few studies have compared outcomes after meniscus suture repair in patients younger than 40 years versus patients 40 years and older. PURPOSE To document failure rates and long-term outcomes after meniscus suture repair by a single surgeon, using the inside-out technique, at a minimum 10-year follow-up in patients younger than 40 years versus(More)
Although injuries to the posterolateral corner of the knee were previously considered to be a rare condition, they have been shown to be present in almost 16% of all knee injuries and are responsible for sustained instability and failure of concomitant reconstructions if not properly recognized. Although also once considered to be the "dark side of the(More)
OBJECTIVE To assess the inter- and intraobserver reproducibility of the original version and different descriptions of the Kellgren and Lawrence classification used in epidemiological studies for osteoarthritis of the knee. METHODS The study included 72 patients with osteoarthritis of the knee. Three medical members of the Brazilian Society of Knee(More)
In a clinical, between-patient study we investigated the effects of a VLMW Heparin fragment (CY 222) versus standard heparin (SH) in plasma exchanges (n = 10) on coagulation factors (CF). Fibrinogen (FGN), II, V, VIIF + X, IX, XI, XII, VIIIc, VIIIRag, VIIIvwf and ATIII, ProtC, ProtS, Plasminogen (PGN), Activated Thromboplastin time (APTT), Prothrombin time(More)
OBJECTIVE To compare the activation of the vastus lateralis (VL) and biceps femoris (BF) muscles during gait, as well VL/BF muscular co-contraction (MCC) between healthy (CG) and anterior cruciate ligament reconstructed (ACL-R) subjects. METHODS Nineteen subjects, ten controls and nine ACL-R patients had a VL and BF electromyogram (EMG) captured to(More)
