Objective The primary aim of this study is to compare tibial tuberosity-trochlear groove (TTTG) distance in patients with or without knee osteoarthritis. Additionally, the variability of tibial tubercle according to trochlear groove was evaluated. Materials and Methods In this retrospective cohort study, TTTG distance was measured with two different methods on magnetic resonance (MR) images. ...

INTRODUCTION The tibial tuberosity to trochlear groove (TTTG) distance in the western population is extensively studied through various modalities such as X-rays, computerised tomography and magnetic resonance imaging. However, to our knowledge there is very little or no literature support to indicate that TTTG distance has been studied in the Indian population. METHODS We therefore undertook...

BACKGROUND The tibial tubercle-trochlear groove (TTTG) distance is used to quantify the degree of lateralization of the patellar tendon insertion on the tibial tubercle relative to the deepest part of the trochlear groove. Disagreement exists as to whether the TTTG distance measured on computed tomography (CT) and magnetic resonance imaging (MRI) can be considered equivalent. PURPOSE To compa...

OBJECTIVES The aim of this study is to evaluate the usefulness of Magnetic Resonance Imaging (MRI) at 20° of knee flexion in patients with patellofemoral pain syndrome (PFPS) caused by suspected patellofemoral malalignment (PFM). MATERIAL AND METHOD Fifty MRIs were performed on 25 patients with PFPS secondary to suspected PFM based on clinical examination, and on 25 patients without PFPS (con...

abstract patellar instability is a multifactorial common knee pathology that has a high recurrence rate, and the symptoms continue and ultimately predispose the patient to chondromalacia and osteoarthritis. tibial tuberosity-trochlear groove distance (tttg) is very important in the assessment of patellofemoral joint instability. the purpose of this study was to report normal value of tttg in ma...

Packaging of the adenovirus (Ad) genome into a capsid is absolutely dependent upon the presence of a cis-acting region located at the left end of the genome referred to as the packaging domain. The functionally significant sequences within this domain consist of at least seven similar repeats, referred to as the A repeats, which have the consensus sequence 5' TTTG-N(8)-CG 3'. In vitro and in vi...

The title compound, C17H18N2S2, exhibits a trans-trans-trans-gauche(+) (tttg (+)) conformation with regard to the NH-CH2-CH2-CH2-NH bond sequence. In the crystal, mol-ecules are connected by N-H⋯S=C and C-H⋯S=C hydrogen bonds, forming a herringbone arrangement along the c-axis direction. The two thioamide groups make dihedral angles of 43.0 (2) and 33.1 (2)° with the adjacent phenyl rings.

The title compound, C18H18O2S2, which lies on an inversion center, adopts a gauche (+)-trans-trans-trans-gauche (-) (g (+) tttg (-)) conformation in the S-CH2-CH2-CH2-CH2-S bond sequence. In the crystal, mol-ecules are packed in a herringbone arrangement through inter-molecular C-H⋯π inter-actions.

INTRODUCTION Genovarum is a common orthopedic problem. Its optimal prompt treatment is an issue of importance. AIM This study was conducted to determine the radiographic changes in patella bone before and after open wedge high tibial osteotomy. MATERIAL AND METHODS In this quasi-experimental study, 43 patients were enrolled and underwent open wedge high tibial osteotomy and the radiographic...

Background: The purpose of this study was to evaluate the significance of the Q angle with respect to the patella position. We assess the correlation between the Q angles (calculated by clinical exam) in different positions and CT indices (with more impression on TTTG) Method: A total number of 68 knee joints of 50 cases entered the study. Clinical examination was used to measure Q angle (in 3 ...
