INTRODUCTION Whether the expression level of MMP-1, MMP-13 and TIMP-1 has association with the degeneration of lateral meniscus after posterior cruciate ligament (PCL) fracture is poorly understood. The aim of this study was to investigate the influence of PCL fracture on lateral meniscus, including morphological changes, histological changes and roles of(More)
OBJECTIVE This study aims to investigate the biomechanical effect of posterior cruciate ligament (PCL) rupture on lateral meniscus. METHOD The stresses of anterior horn, caudomedial part and posterior horn of lateral meniscus in cadaveric knees were recorded when the knee joints were loaded 200 to 1000 N at 0, 30, 60 and 90° of flexion. Twelve knees were(More)
BACKGROUND The relationship between lateral meniscus tear and posterior cruciate ligament injury is not well understood. The present study aims to investigate and assess the effect of posterior cruciate ligament rupture on lateral meniscus radial displacement at different flexion angles under static loading conditions. METHODS Twelve fresh human cadaveric(More)
BACKGROUND Tenosynovial giant cell tumor (TGCT) is a relatively rare disease often misdiagnosed as osteoarthritis. Synovectomy or arthroplasty is the recommended treatment option, but recurrence is common after surgery. This study aimed to determine the prognosis of patients with advanced TGCT that was diagnosed incidentally during total knee arthroplasty(More)
We construct new randomized algorithms to find the exact solutions to the shortest and closest vector problems (SVP and CVP) in Euclidean norm (2) for integral lattices. Not only the minimal 2-norm of non-zero lattice vectors in SVP and the minimal 2-distance in CVP, but also how many lattice vectors reach those minimums can be simultaneously computed by(More)
We construct an innovative SVP(CVP) solver for ideal lattices in case of any relative extension of number fields L/K of degree n where L is real(contained in R). The solver, by exploiting the relationships between the so-called local and global number fields, reduces solving SVP(CVP) of the input ideal A in field L to solving a set of (at most n) SVP(CVP)(More)
BACKGROUND AND OBJECTIVES Deproteinization is an indispensable process for the elimination of antigenicity in xenograft bones. However, the hydrogen peroxide (H2O2) deproteinized xenograft, which is commonly used to repair bone defect, exhibits limited osteoinduction activity. The present study was designed to develop a new method for deproteinization and(More)
