Background: Anterior cruciate ligament is the most common tear in knee and its primary role to provide stability joint. Aim of study describe various secondary signs that are helpful diagnosing partial/complete ACL tear. MRI offers distinct advantages over arthroscopy as a means evaluating ACL. evaluation effective preventing unnecessary by assessing severity coexisting injuries. Methods: In th...

We used three-dimensional movement analysis by computer modelling of knee flexion from 0 degrees to 50 degrees in 14 knees in 12 patients with recurrent patellar dislocation and in 15 knees in ten normal control subjects to compare the in vivo three-dimensional movement of the patella. Flexion, tilt and spin of the patella were described in terms of rotation angles from 0 degrees . The location...

The longitudinal relaxation time T(1) of native cartilage is frequently assumed to be constant. To redress this, the spatial variation of T(1) in unenhanced healthy human knee cartilage in different compartments and cartilage layers was investigated. Knees of 25 volunteers were examined on a 1.5 T MRI system. A three-dimensional gradient-echo sequence with a variable flip angle, in combination ...

We purified lipoamide dehydrogenase from cells of Pseudomonas putida PpG2 grown on glucose (LPD-glu) and lipoamide dehydrogenase from cells grown on valine (LPD-val), which contained branched-chain keto acid dehydrogenase. LPD-glu had a molecular weight of 56,000 as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and LPD-val had a molecular weight of 49,000. The pH opti...

CASE REPORT We present a case of a 57 year old female whose patella became locked above a femoral osteophyte. She attended A & E at the Royal Victoria Hospital, Belfast. She had been pushing a chair forward under a table with her left knee when she felt a 'pop' inside it followed by severe pain. She was unable to bend or weightbear on the knee. Her left knee was previously asymptomatic with no ...

Osteochondral and pure chondral lesions of the knee are common after patellar dislocations. There multiple described techniques for fixation these lesions, including metallic screws, bioabsorbable implants, suture devices. The purpose this article is to describe a surgical technique lateral condyle lesion using knotless all-suture anchors, with second-look arthroscopy illustrating healing carti...

The epidermal growth factor receptor (EGFR) plays an essential role during development and diseases including cancer. Lamellipodin (Lpd) is known to control lamellipodia protrusion by regulating actin filament elongation via Ena/VASP proteins. However, it is unknown whether this mechanism supports endocytosis of the EGFR. Here, we have identified a novel role for Lpd and Mena in clathrin-mediat...

an enhanced displacement feedback structural control procedure is presented for performance-based design in this paper. at first, a comparative study is implemented assessing three most common active control algorithms including state, acceleration, and displacement feedback controls. the advantage of the displacement feedback algorithm for active control of structures against earthquakes is de...

BACKGROUND The impetus for the use of patellar straps in the treatment of patellar tendinopathy has largely been based on empirical evidence and not on any mechanistic rationale. A computational model suggests that patellar tendinopathy may be a result of high localized tendon strains that occur at smaller patella-patellar tendon angles (PPTAs). HYPOTHESIS Infrapatellar straps will decrease t...
