An acetabular labrum tear or hip labrum tear is a common injury of the acetabular labrum resulting from a number of causes including running, hip dislocation, and deterioration with ageing. Most are thought to result from a gradual tear due to repetitive microtrauma .
More moderate damage responds better to arthroscopic labral repair, a procedure in which surgical anchors are drilled into the bony acetabular rim and sutures are used to reapproximate the damaged labral tissue. The most severe degrees of labral pathology is often unresponsive to labral repair, with damage far too diffuse for focal debridement.
The acetabular labrum (glenoidal labrum of the hip joint or cotyloid ligament in older texts) is a fibrocartilaginous ring [1] [2] [3] which surrounds the circumference of the acetabulum of the hip, deepening the acetabulum. The labrum is attached onto the bony rim and transverse acetabular ligament. It is triangular in cross-section (with the ...
Previous repair procedures, however, always generated fibrocartilage or, at best, a combination of hyaline and fibrocartilage repair tissue. Autologous chondrocyte implantation (ACI) procedures are cell-based repairs that aim to achieve a repair consisting of healthy articular cartilage.
Standard arthroscopic treatment of symptomatic cam FAI involves debridement (resection) or repair of any labral [10] and chondral injuries [11] in the central compartment of the hip, and subsequent reshaping of the head-neck junction of the upper femur (osteochondroplasty) in the peripheral compartment [12] [13] using high-speed motorised burrs ...
[medical citation needed] For example, a hip joint that is affected by osteoarthritis may be replaced entirely (total hip arthroplasty) with a prosthetic hip. This would involve replacing both the acetabulum (hip socket) and the head and neck of the femur. The purpose of this procedure is to relieve pain, to restore range of motion and to ...
