During each step, arthroscopy was maintained in the anterolateral (AL) portal and was focused on the articular side of the necrotic area to ensure that the subchondral bone
and articular cartilage were not violated.
4,5] In addition, subchondral bone
pathology may cause neuropathy after destruction of the chondral structure, because the subchondral bone
is densely innervated.
The disease involves cartilage degeneration, intraarticular synovial inflammation, and subchondral bone
The goal of the procedure is to improve the structural integrity of the subchondral bone
in an attempt to promote subchondral bone
remodelling to relieve pain and associated symptoms and potentially prevent or limit the progression to osteoarthritis.
On the ventrodorsal view, that fracture appeared to extend through the cranial cortex of the humerus at 2 sites, just distal to the subchondral bone
of the humeral head, and to the level of the proximal diaphysis.
A subchondral drill is included for use in arthrodesis joint preparation; the instrument provides approximately 10 mm of controlled drilling of subchondral bone
with a stop to help prevent deeper penetration.
In a late stage of OA, cartilage thickness decreases to an extent that subchondral bone
is exposed, leading to joint damage and causing severe pain (Setton et al.
Further fixed angle locking distal radius plates have distinct advantage over conventional plates providing stability by fixed angle locking and supporting the subchondral bone
and resisting the axial forces across the wrist that lead to settling and loss of reduction.
Articular cartilage lesions are a debilitating disease resulting in fibrillation and subsequent degradation which can also involve the subchondral bone
and lead to the development of OA [16, 17].
2) The matrix environment of hyaline cartilage is different from that of subchondral bone
in biological, physical and chemical characteristics.
Examination revealed a swollen and tender elbow, with plain x-ray confirming a subchondral bone
disorder (osteochondral defect) of the capitellum.
9,11] In our case, the MRI of hip and knees that was taken a few weeks after the onset of symptoms was determined BME, despite joint space and subchondral bone
, was normal in accordance with TO.
