Arthroscopy‐Assisted Type 2 Posterior Horn Lateral Meniscus Transtibial Root Repair And Concurrent Inside‐Out Lateral Meniscus Horizontal Cleavage Tear Repair With an Anterolateral Ligament Reconstruction Utilizing Iliotibial Band Autograft

Arthroscopy Techniques, EarlyView.
Abstract The anterior cruciate ligament (ACL) and anterolateral ligament (ALL) play key roles in maintaining rotational stability of the knee joint. Injuries that cause ACL tears have been shown to also frequently compromise the integrity of the ALL.

A Modified Anatomical All‐Inside Double‐Bundle Anterior Cruciate Ligament Reconstruction Technique

Arthroscopy Techniques, EarlyView.
Abstract Arthroscopic anterior cruciate ligament (ACL) reconstruction (ACLR) is the standard surgical treatment for ACL injuries and is most commonly performed using anatomical single‐bundle (SB) or double‐bundle (DB) techniques. With the development of the all‐inside technique, the all‐inside SB technique using socket‐based tunnels and cortical ...

Arthroscopic Treatment of Cartilage Lesions With Microfracture and BST-CarGel

, 2014
Bone marrow stimulation techniques for the treatment of articular cartilage defects such as microfracture so far have solely reproduced mechanically inferior fibrous cartilage tissue, which might result in unsatisfactory clinical results at midterm ...

Shear behavior of bolt–grout interfaces under constant normal stiffness: Influence of grout strength and thickness

Deep Underground Science and Engineering, EarlyView.
The effects of grout strength and thickness on the shear behavior of bolt–grout interfaces (BGI) under constant normal stiffness conditions are investigated. Shear strength, failure modes, and acoustic emission characteristics are examined. The findings reveal that grout strength exerts a significantly greater influence on BGI shear strength and ...

Advancing mine pillar design: Evaluating traditional methods and integrating AI for enhanced stability of pillars in the Great Dyke, Zimbabwe

Deep Underground Science and Engineering, EarlyView.
B1 is bord width 1, B2 is bord width 2, L is the pillar length, W is the pillar width, red color and letter A represent the pillars, and white color and number 1 represent excavated areas. Pstress is the average pillar stress; σv is the vertical component of the virgin stress, MPa; and e is the areal extraction ratio. e = B o B o + B P ${\rm{e}}=\frac{{

Outcomes Following Treatment of Talar Osteochondral Lesions with a Mixture of Particulate Allogenic Cartilage Extracellular Matrix and Bone Marrow Aspirate Concentrate: A Case Control Series

Orthopaedic Journal of Sports Medicine, 2019
Objectives: There continues to be a general lack of consensus regarding the optimal treatment for osteochondral lesions of the talus (OLTs). Microfracture, once considered the gold-standard, has been associated with poor long-term results due to the ...

Microfracture Surface Geochemistry and Adherent Microbial Population Metabolism in TCE-Contaminated Competent Bedrock

, 2007
A TCE-contaminated competent bedrock site in Portsmouth, NH was used to determine if a relation existed between microfracture surface geochemistry and the ecology and metabolic activity of attached microbes relative to terminal electron accepting ...

Mechanistic insights across curing regimes for enzymatic and biopolymer‐optimized reinforcement in rock masses

Deep Underground Science and Engineering, EarlyView.
This study examines the effects of curing temperature on the mechanical behavior of underground rock masses treated with enzyme‐induced calcite precipitation (EICP) and an innovative biopolymer‐modified EICP (BP‐EICP). Abstract Biocementation is an innovative and sustainable technique for reinforcing weak and weathered rock masses in natural and ...
