Articular cartilage is a connective tissue overlying the ends of bones that provides smooth joint surfaces. Healthy cartilage is essential to the proper functioning of joints within the body. Cartilage is composed of cells embedded in an extracellular matrix of collagen fibers and proteoglycans.
Bone grafting is a surgical procedure that replaces missing bone in order to repair bone fractures that are extremely complex, pose a significant health risk to the patient, or fail to heal properly. Some small or acute fractures can be cured without bone grafting, but the risk is greater for large fractures like compound fractures.
Arthroscopic anterior cruciate ligament (ACL) reconstruction (right knee). The tendon of the semitendinosus muscle was prelevated, folded and used as an autograft (1). It appears through the remnant of the injured original ACL (3). The autograft then courses upwardly and backwardly in front of the posterior cruciate ligament (2).
Autologous articular cartilage transfer from a non-weight-bearing area to the damaged area, called osteochondral autograft transfer system, is one possible procedure that is being studied. [140] When the missing cartilage is a focal defect, autologous chondrocyte implantation is also an option. [141]
In orthopaedic medicine, a bone graft can be sourced from a patient's own bone in order to fill space and produce an osteogenic response in a bone defect. However, due to the donor-site morbidity associated with autograft, other methods such as bone allograft and bone morphogenetic proteins and synthetic graft materials are often used as alternatives.
An articular cartilage defect that initially may be small still has the potential to have a physical and chemical "domino effect" on the surrounding "normal" articular cartilage. [2] Pitkin et al. (2014) discovered a potential etiology for articular cartilage damage. When the interarticular transmission of pressures is interrupted so that ...
The most common form of arthritis, osteoarthritis (also known as degenerative joint disease), occurs following trauma to the joint, following an infection of the joint or simply as a result of aging and the deterioration of articular cartilage. Furthermore, there is emerging evidence that abnormal anatomy may contribute to early development of ...
Damage can occur to the articular cartilage, or labral cartilage (soft tissue, ring-shaped bumper of the socket), or both. [4] The condition may be symptomatic or asymptomatic. It may cause osteoarthritis of the hip. [1] Treatment options range from conservative management to surgery. [5]
