The aim of this study was to determine if microfractures improve the outcome of high tibial osteotomy in patients with medial compartmental osteoarthritis in genu varum. Forty patients presenting with Outerbridge grade III and IV chondropathies on the femoral and/or the tibial joint surface underwent high tibial osteotomy with Puddu plates (Arthrex, Inc, Naples, Florida) for primary medial comp...

Shock wave therapy can induce a period of cutaneous analgesia after treatment. Shock wave therapy does not induce microfractures nor does it have an effect on the modulus of elasticity of bone.

The time history of He concentrations in gas samples collected and analyzed by Clarke et al. is modeled. A deficiency relative to expected helium suggests loss through microfractures identified by Farkas.

Introduction Cartilage lesions are the most common cause of chronic knee pain. The current treatment options consist in conservative strategies, such as visco-supplementation and platelet-rich plasma injections, and surgical management including debridement of the chondral lesion, bone marrow stimulation with microfractures and osteochondral transplant. In this study we combined arthroscopic mi...

A homogenization result is given for a material having brittle inclusions arranged in a periodic structure. According to the relation between the softness parameter and the size of the microstructure, three different limit models are deduced via Γ-convergence. In particular, damage is obtained as limit of periodically distributed microfractures.

This study aimed to carry out the data-driven evaluation of pores and microfractures in tight conglomerate reservoirs combining machine learning complex geometric analysis, then investigate internal control factors reservoir damage. Results show that for Upper Wuerhe formation Mahu sag Xinjiang China, average contribution rate fluid storage seepage is 7.1 times pores, dominate seepage. Besides,...

The Lower Silurian black shale in the Southeast of Chongqing is great potential accumulation gas South China. In order to understand pore system these shales, mercury porosimetry, surface area study, mineralogy and image analyses by scanning electronic microscopy were performed. Four major types (interparticle pores, intraparticle organic-matter pores microfractures) classified under observatio...
