Humeral head in rotator cuff tear arthropathy shows reduced cartilage damage and uniform subchondral bone osteoporosis: a histomorphometric analysis [PDF]

JSES International
: Background: This study histologically assessed alterations in the articular cartilage, subchondral bone, and trabecular bone in patients with rotator cuff tear arthropathy (CTA) versus those with osteoarthritis (OA) of the humeral head.

Larger preoperative medial meniscus extrusion is associated with insufficient pain relief following pullout repair for medial meniscus posterior root tears [PDF]

J Exp Orthop
Abstract Purpose We aimed to evaluate preoperative factors associated with postoperative pain after transtibial pullout repair for medial meniscus posterior root tears (MMPRT), focusing on patient characteristics and imaging findings, including bone morphology and preoperative medial meniscus extrusion (MME).

Microstructural adaptations of the subchondral bone are related to the mechanical axis deviation in end stage varus OA knees [PDF]

European Cells & Materials, 2023
Recent studies highlighted the crucial contribution of subchondral bone to OA development. Yet, only limited data have been reported on the relation between alteration to cartilage morphology, structural properties of the subchondral bone plate (SBP) and

Microdrilling Resulted in Less Subchondral Bone Destruction Than a Traditional Microfracture Awl for Articular Cartilage Defect Bone Marrow Stimulation

Arthroscopy, Sports Medicine, and Rehabilitation, 2023
Purpose: The purpose of this study was to compare bone marrow stimulation using micro-computed tomography (micro-CT) analysis of an abrasion arthroplasty technique, drilling k-wire technique, traditional microfacture awl, or a microdrill instrument for ...

Magnetic resonance imaging of avascular necrosis of the femoral head: predictive findings of total hip arthroplasty

Acta Radiologica Open, 2021
Background Avascular osteonecrosis of the femoral head (AVNFH) is an ischemic condition which despite different treatments often leads to collapse of the femoral head and to total hip arthroplasty.

Associations of osteoclastogenesis and nerve growth in subchondral bone marrow lesions with clinical symptoms in knee osteoarthritis

Journal of Orthopaedic Translation, 2022
Background/objective: Subchondral bone marrow lesions (BMLs) are common magnetic resonance imaging (MRI) features in joints affected by osteoarthritis (OA), however, their clinical impacts and mechanisms remain controversial.

Revision Lateral Femoral Condyle Osteochondral Allograft Transplantation With the Snowman Technique After Failed Previous Oblong Osteochondral Allograft

Arthroscopy Techniques, 2023
Osteochondral allograft transplantation provides components of both cartilage and subchondral bone and can be used in large and multifocal defects where autologous procedures are limited by donor-site morbidity. Osteochondral allograft transplantation is
