Introduction The temporomandibular joint (TMJ) in carnivores is a ginglymoid (hinge) joint in which the preglenoid and postglenoid processes limit anteroposterior movements of the mandibular condyle, permitting almost exclusively rotation around a transverse axis (Becht, 1953; Maynard Smith & Savage, 1959; Noble, 1973; Freeman, 1979; Crompton, 1981). In contrast, the TMJ in anthropoid primates ...

Mechanical alignment with conventional total knee arthroplasty (TKA) instruments often requires collateral ligament releases, which result in a high prevalence of adduction and reverse axial rotation (external rotation) of the tibial component during knee flexion with a variety of component designs. We used a radiographic image-matching technique to determine the contact kinematics during stand...

Introduction: Cone-Beam Computed Tomography (CBCT) imaging provides an excellent representation of the temporomandibular joint bone tissues. Objective: The aim of this study was to investigate morphological changes of the mandibular condyle from childhood to adulthood using CBCT. Methods: A cross-sectional study was conducted in 36 condyles of 18 subjects from 3 to 20 years of age. Condyles wer...

OBJECTIVES To ascertain thickness measurements on the anterior cruciate ligament (ACL) in its middle third on magnetic resonance imaging (MRI) scans and to assess whether there is any association between variations in ligament thickness and patients' heights and ages, along with variations in the anatomical measurements on the knee. METHODS MRI scans on 48 knees were evaluated. The anteropost...

BACKGROUND Assessment of degenerative changes of the cartilage is important in knee cartilage repair surgery. Magnetic Resonance Imaging (MRI) T2 mapping and delayed Gadolinium Enhanced MRI of Cartilage (dGEMRIC) are able to detect early degenerative changes. The hypothesis of the study was that cartilage surrounding a focal cartilage lesion in the knee does not possess degenerative changes. ...

INTRODUCTION The meniscus has an important role in force transmission across the knee, but a detailed three-dimensional (3D) morphometric shape analysis of the lateral meniscus to elucidate subject-specific function has not been conducted. The aim of this study was to perform 3D morphometric analyses of the lateral meniscus in order to correlate shape variables with anthropometric parameters, t...

PURPOSE To assess the outcome after using the Shaft-Condylar angle (SCA) as intraoperative reference for sagittal plane correction in displaced lateral humeral condyle fractures in children presented 3-weeks after injury. METHODS Ten children, with delayed presentation of a displaced lateral humeral condyle fracture and undergoing surgery during 1999-2011, were reviewed. The goal was to obtai...

We report the case of a patient with intraosseous ganglion in the lateral femoral condyle. An 11-year-old girl presented with right knee pain following a twisting injury. Plain radiographs of the knee showed a small circumscribed radiolucency with a thin sclerotic margin in the subchondral region of the lateral femoral condyle. Although the image findings and location are not typical, the lesio...

after Mobile-bearing Total Knee Arthroplasty +Ishii, Y; Noguchi, H; Takeda, M; Sato, J +Ishii Orthopaedic & Rehabilitation Clinic, Gyoda, Saitama, JAPAN [email protected] INTRODUCTION: Postoperative studies using X-ray analyses have reported contradictory findings regarding whether PCO had an effect on flexion after total knee arthroplasty (TKA), since correctly recognizing which condyle ref...
