Abstract:
Focal early osteoarthritis (OA) or degenerative lesions account for 60% of treated cartilage defects each year. The current cell-based regenerative treatments have an increased failure rate for treating degenerative lesions compared to traumatic defects. Mesenchymal stem cells (MSCs) are an alternative cell source for treating early OA defects, due to their greater chondrogenic potential, compared to early OA chondrocytes. Low oxygen tension or physioxia has been shown to enhance MSC chondrogenic matrix content and could improve functional outcomes of regenerative therapies. The present invest

Abstract:
AbstractFocal chondral or osteochondral lesions of the knee are common lesions involving either the cartilage layers or the cartilage layers and the subchondral bone. Despite their heterogeneous clinical presentation, they are important risk factors for the premature development of osteoarthritis. Therefore, early detection of osteochondral lesions and focal cartilage defects is crucial. In symptomatic (osteo-)chondral lesions, numerous therapeutic strategies, ranging from conservative treatment to surgical procedures such as marrow stimulation, osteochondral autograft transplantation, or auto

Abstract:
Osteochondritis dissecans of the knee is an idiopathic, focal, subchondral-bone abnormality that can cause instability or detachment of a bone fragment and overlying articular cartilage, with subsequent progression to osteoarthritis. The degree of lesion instability is best assessed by magnetic resonance imaging. Unstable lesions require operative management with fragment fixation. Level of evidence: V.

Abstract:
Focal chondral defects are common lesions of the articular cartilage. They are predominantly found on the medial femoral condyle and often progress to osteoarthritis of the knee. Various conservative treatment options are available. The conservative treatment might reduce pain and delay the progress of degenerative processes. However, restoration of the articular cartilage cannot be accomplished. If the conservative treatment fails unicompartmental arthroplasty, patellofemoral joint replacement or focal resurfacing are reasonable options to postpone total knee arthroplasty.

Hyaline cartilage’s inability to self-repair can lead to osteoarthritis and joint replacement. Various treatments, including cell therapy, have been developed for cartilage damage. Autologous chondrocyte implantation (ACI) is considered the best option for focal chondral lesions.

Abstract:
Cartilage defects represent a common problem in orthopaedic practice. Predisposing factors include traumas, inflammatory conditions, and biomechanics alterations. Conservative management of cartilage defects often fails, and patients with this lesions may need surgical intervention. Several treatment strategies have been proposed, although only surgery has been proved to be predictably effective. Usually, in focal cartilage defects without a stable fibrocartilaginous repair tissue formed, surgeons try to promote a natural fibrocartilaginous response by using marrow stimulating techniques, such

This chapter examines the bone conditions of osteonecrosis, osteochondrosis, and osteochondritis dissecans. Osteonecrosis is ischaemia of bone caused by a range of conditions, including trauma, which cause intravascular or extravascular obstruction of blood flow to bone. Many cases are associated with pro-thrombotic conditions. Osteonecrosis can be asymptomatic, but if progressive often leads to secondary (adjacent) joint destruction. Diagnosis is made by magnetic resonance imaging. Aside from treatment of any underlying cause, treatment options include analgesics, vasodilators, and surgery. T

Over the past several decades, Magnetic Resonance Imagining has become a standard in cartilage thickness analysis (Gray 2008, Potter 2006). However, MRI analysis has not been used to indicate patients with early osteoarthritic (OA) cartilage changes for early intervention procedures (EIP) such as grafts or minimally-invasive unicondylar knee replacements.

Abstract:
Articular cartilage exhibits a poor healing response to injury that necessitates surgical intervention to repair or replace damaged tissue. Treatment options, however, are dependent on the location and size of the defect site. For small focal defects (<2 cm 2), microfracture is the primary method of treatment [8] despite the production of biologically inferior cartilage. For lesions greater than 10 cm 2 where the articular cartilage loss and morphology of the condyle is distorted, a fresh osteoarticular allograft is most likely to succeed [3], while posing a significant surgical challenge r

Damage to articular cartilage is a common condition affecting the joints of millions of people. This is a major problem considering the poor regenerative capacity of adult articular cartilage and the disability and pain that accompanies these injuries [13].
