The initiation of bitumen-filled microfractures was analysed in the organic-rich Maastrichtian carbonate mudrocks Jordan, which show great potential as source rocks and for a future unconventional hydrocarbon play. A modelling approach performed to assess possible scenarios causing horizontal small-scale (mm cm length) bitumen fractures (microfractures) at immature stage. aim back-calculate how...

Damage to soil structure caused by strong earthquakes is one of the main reasons for post-earthquake geohazard development. To investigate nonlinear dynamic behaviors loess, a pre-shock reconsolidation test was designed simulate process loess undergoing earthquake and in natural state. Furthermore, triaxial tests specimens before after action consolidation stabilization with different over-cons...

OBJECTIVE The major aim of the study was (1) to compare the physiotherapy management in patients treated with autologous chondrocyte implantation (ACI) versus microfracture (MF) at the knee using a standardized rehabilitation protocol; and (2) to investigate the effect of activities in low-load conditions after surgery on the functional recovery was explored. DESIGN 95 physiotherapists receiv...

Purpose  The aims of this paper are to report the rate and risk factors for the failure of the most common cartilage repair technique, and analyze the most important factors that could influence the choice of a specific surgical treatment to revise a failed cartilage repair. Methods  A review of the literature was performed focusing on failed cartilage repair and related treatments. Two of the ...

Postoperative rehabilitation programs following articular cartilage repair procedures will vary greatly among patients and need to be individualized based on the nature of the lesion, the unique characteristics of the patient, and the type and detail of each surgical procedure. These programs are based on knowledge of the basic science, anatomy, and biomechanics of articular cartilage as well a...

Microfracture (MFx) is currently the recommended option for the treatment of small cartilage defects but is not regarded as suitable for the treatment of defects larger than 2.5 cm(2). To extent its applicability to medium-sized defects MFx has been combined with a collagen type I/III matrix (Chondro-Gide(®)). This technique is called Autologous Matrix-Induced Chondrogenesis (AMIC(®)) and meanw...

OBJECTIVE To demonstrate a cost benefit while using disposable laser fibers as compared with reusable laser fibers. Flexible ureteroscopy (FURS) is a central component of endourology. It is vital that for service provision and training purposes, costs are kept down while delivering this service. Laser fibers are known to damage scopes causing high repair and/or replacement costs. MATERIALS AN...
