#1
Xia Wang, Win Min Oo, James M Linklater
While OA is predominantly diagnosed on the basis of clinical criteria, imaging may aid with differential diagnosis in clinically suspected cases. While plain radiographs are traditionally the first choice of imaging modality, MRI and US also have a valuable role in assessing multiple pathologic features of OA, although each has particular advantages and disadvantages. Although modern imaging modalities provide the capability to detect a wide range of osseous and soft tissue (cartilage, menisci, ligaments, synovitis, effusion) OA-related structural damage, this extra information has not yet favourably influenced the clinical decision-making and management process...

PURPOSE: The aims of this study are to describe the epidemiological characteristics of anterior cruciate ligament reconstructions in a private hospital in Brazil and to determine trends in medical practice for comparison with previous studies. METHODS: We retrospectively reviewed the anterior cruciate ligament institutional register to obtain data from all patients who underwent primary anterior cruciate ligament reconstruction from July 2014 to June 2016. Descriptive statistics were used to summarize the sample...

Sudden death resulting from intracardiac leiomyomatosis is rare. In this case, a 50-year-old woman was found to have intracardiac leiomyomatosis, which originated in veins in the broad ligament. Tumor filled the entire inferior vena cava and extended into the right heart where it had embolized and occluded the right main pulmonary artery. The mechanism of death was sudden right heart failure.

AIM: To evaluate the cytocompatibility of Biodentine and iRoot FS with human periodontal ligament cells (hPDLCs). METHODOLOGY: hPDLCs were characterized by flow cytometry and immunocytochemical analysis. hPDLC adhesion was assessed by scanning electron microscopy at day 3; proliferation by live/dead assay at day 1, 3 and 7; and osteogenic differentiation by alkaline phosphatase (ALP) activity staining, ALP quantification analysis and qRT-PCR at day 7 and 14. Data were analysed with ANOVA and independent sample t-tests with SPSS 21...

The popliteomeniscal fascicules (PMFs) provide the attachment of the lateral meniscus to the popliteus musculotendinous region, forming the floor and the roof the popliteal hiatus. In the second half of 1900's, some anatomic studies claim the important function of the PMF as stabilizers of the lateral meniscus; these anatomical structures work in conjunction with the popliteus musculotendinous unit to prevent excessive lateral meniscal movement and possible meniscus subluxation. A correct diagnosis of the PMFs pathology is crucial to establish the suitable surgical treatment for each patient...

CONTEXT:   Aberrant biomechanics may affect force attenuation at the knee during dynamic activities, potentially increasing the risk of sustaining a knee injury or hastening the development of osteoarthritis after anterior cruciate ligament reconstruction (ACLR). Impaired quadriceps neuromuscular function has been hypothesized to influence the development of aberrant biomechanics. OBJECTIVE:   To determine the association between quadriceps neuromuscular function (strength, voluntary activation, and spinal-reflex and corticomotor excitability) and sagittal-plane knee biomechanics during jump landings in individuals with ACLR...

Range of motion (ROM) measured objectively in nodal hand osteoarthritis (NHOA) is missing. Evaluation of collateral ligaments by ultrasound (US) is unknown in NHOA also. To compare ROM in interphalangeal joints in housewives with nodal OA, with a control group by a digital system using angle to voltage (Multielgon). The second objective was to assess correlation between collateral radial and ulnar ligaments thickness and ROM. For this cross-sectional observational study, we assessed 60 hands with symptomatic NHOA and 30 hands of healthy housewives matched for age...

Current total knee replacement designs work to address clinically desired knee stability and range of motion through a balance of retained anatomy and added implant geometry. However, simplified implant geometries such as bearing surfaces, posts, and cams are often used to replace complex ligamentous constraints that are sacrificed during most total knee replacement procedures. This article evaluates a novel total knee replacement design that incorporates synthetic ligaments to enhance the stability of the total knee replacement system...

Anterior cruciate ligament injury is one of the most common injuries of knee joint. Arthroscopic reconstruction of anterior cruciate ligament is the most commonly performed procedure. A variety type of fixation techniques are being used nowadays, such as interference screw, cortical suspension fixation and transfix, all of which can achieve good effect, with both advantages and disadvantages. However, the healing of reconstructed grafts is a complicated and long-term process, which can be affected by many factors...

Patients who suffer from the recurrent patellar dislocation mainly show the recurrent dislocation of patellar, giving way, most patients have the history of trauma or dysplasia of keen joint. Traditional therapies of recurrent patellar dislocation include medical retinaculum placation, lateral retinaculum release, tibial tubercle osteotomy, femoral trochleoplasty etc. In recent years, with the development of anatomical and biomechanical researches on medial patellofemoral ligament(MPFL), more and more experts focus on the role of MPFL played in preventing the patellar dislocation...

BACKGROUND: With the improvement of the surgical technique of Laparoscopic pancreaticoduodenectomy (LPD), indications will be extended to patients with vascular invasion. With LPD, vascular grafts for reconstruction are more frequently needed because adequate mobilization is not always done and vascular grafts can safely facilitate reconstruction. We describe our experience of reconstruction with the falciform ligament. METHODS: Venous reconstruction is performed after removal of the specimen...

We describe an arthroscopic technique for the treatment of labral pathology and femoroacetabular impingement that provides excellent access to the central and peripheral compartments while preserving the biomechanically crucial components of hip joint stability. The hip capsule and the ligaments within it have been shown to be integral to hip biomechanical stability. Other popular techniques such as interportal and T-capsulotomy inherently damage the capsuloligamentous complex of the hip and can be associated with postoperative gross instability, micro-instability, heterotopic ossification, and seroma...
