Arthroscopic Autologous Minced Cartilage Implantation for Subchondral Insufficiency Fracture of the Knee. [PDF]
Arthrosc TechAbstract Subchondral insufficiency fracture of the knee, previously known as spontaneous osteonecrosis of the knee, commonly affects the medial femoral condyle and may progress to subchondral collapse and eventually osteoarthritis. Joint‐preserving options for focal medial femoral condyle lesions remain limited, particularly in middle‐aged patients ...

Arthroscopic Segmental Labral Reconstruction Using a Presutured Iliotibial Band Allograft Soaked in Bone Marrow Aspirate Concentrate. [PDF]
Arthrosc TechAbstract Labral reconstruction is a surgical procedure in which a graft is used to replace irreparable acetabular labral tissue. Biologic augmentation with bone marrow aspirate concentrate harvested from the ipsilateral iliac crest is increasingly used to enhance graft incorporation and potentially improve functional outcomes, especially in patients ...

L-Capsulotomy and Anatomic Repair of Zona Orbicularis: Hip Arthroscopy Capsular Management for Femoroacetabular Impingement Syndrome. [PDF]
Arthrosc TechAbstract As an increasingly recognized technique, the longitudinal outside‐in capsulotomy (LOIC) has the advantages of reducing damage to the iliofemoral ligament and decreasing the impact on hip joint stability. However, it has limitations in exposing and addressing acetabular‐sided lesions, particularly in femoroacetabular impingement syndrome cases ...

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links
Geophysical Monograph Series, Page 191-228., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Outcomes of arthroscopic
Journal of Orthopaedic Surgery and Research, 2011 Background A Hill-Sachs lesion of the humeral head after a shoulder dislocation is clinically insignificant in most cases. However, a sizable defect will engage with the anterior rim of the glenoid and cause instability even after anterior glenoid ...
