The treatment and prognosis of labral tears of the hip depend primarily on whether there is concomitant injury of the adjacent acetabular articular cartilage. We asked whether a delamination cyst on the preoperative plain radiographs correlated with delamination of the acetabular articular ...

Background: Treatment of hip dysplasia has focused on corrective osteotomy surgery, while hip arthroscopy remains controversial. Improved understanding of intra-articular disease patterns associated with hip dysplasia will help delineate the role of arthroscopy as an adjunct to osteotomy surgery for dysplastic hips. Purpose: The authors set out to describe the ...

The relatively thin cartilage of the hip joint, as well as its complex geometry, poses challenges for standardized, reproducible assessment of cartilage and the acetabular labrum. With appropriate pulse sequence parameters, however, accurate, reproducible assessment of cartilage and the labrum is feasible. More ...

Articular cartilage lesions and osteochondral defects remain a difficult problem for the patient and physician. A variety of procedures and treatments have been proposed to lessen symptoms and restore the articular surface. The knee joint has been the focus of the vast majority of these cartilage restoration ...

Quantification of the hip cartilages is clinically important. In this study, we propose an automatic technique for segmentation and visualization of the acetabular and femoral head cartilages based on clinically obtained multi-slice T1-weighted MR data and a hybrid approach. We follow a knowledge based approach by employing several ...

INTRODUCTIONExtensive bone loss associated with revision hip surgery is a significant orthopaedic challenge. Acetabular reconstruction with the use of impaction bone grafting and a cemented polyethylene cup is a reliable and durable technique in revision situations with cavitatory acetabular bone defects. Some use cancellous graft alone whilst others ...

A model of synovial fluid (SF) filtration by articular cartilage (AC) in a step-loaded spherical synovial joint at rest is presented. The effects of joint pathology (such as a depleted acetabular labrum, a depleted cartilage superficial zone consistent with early osteoarthritis and an inflammatory SF) on the ...

The past decade has seen unprecedented growth in the number of hip arthroscopies. Acetabular labral tears are the leading indication for arthroscopy of this joint. However, labral anatomy and function, as well as the effects of labral tears and surgical outcomes, have only recently been studied. Labral tears may cause pain and microinstability of the hip joint. They also may ...

There have been considerable recent advances in the understanding and management of femoroacetabular impingement and associated labral and chondral pathology. We have developed a classification system for acetabular chondral lesions. In our system, we use the six acetabular zones previously described by Ilizaliturri et al. The ...

The aim of this study was to evaluate the role of multidetector CT (MDCT) arthrography in the diagnosis of intra-articular hip pathology. A retrospective review of 96 patients who had undergone CT hip arthrography was performed. Data regarding the presence of a labral tear, paralabral cyst, chondral loss, acetabular version, femoral morphology and ...

Pathology of the acetabular labrum plays an increasing role in the treatment of hip pain. Hip arthroscopy has proven its clinical value as a useful procedure for successful treatment of labral tears. Until today, only a few studies have investigated the influence of articular cartilage defects on the clinical outcome of partial ...

Slipped capital femoral epiphysis is usually treated with in situ fixation to prevent progression of deformity. However, slipped capital femoral epiphysis always is associated with structural risk factors for hip dysfunction in addition to the risk of slip progression. Femoro-acetabular impingement causes some mechanical abnormality in every hip affected by slipped capital ...

Acetabular labral tears are usually seen in individuals in whom the hip is exposed to elevated axial and torsional forces. In our experience we have encountered a series of female patients in whom symptom onset was during pregnancy or obstetric labour. We reviewed our patient database to identify all patients who had undergone hip arthroscopy in our hospital. The records of ...

Lesions to articular cartilage can be difficult to treat and directly impact surgical outcome in hip arthroscopy. This article describes a direct cartilage suture repair technique for a young, active individual with full-thickness acetabular cartilage delamination. Lesions of this type are ...

This book contains six parts, each consisting of several papers. The part titles are: Cartilage Matrix Components; Biosynthesis and Characterization of Cartilage--Specific Matrix Components and Events; Cartilage Metabolism; In Vitro Studies of Articular Cartilage Metabolism; Normal and ...

The purpose of the study was to demonstrate the prevalence of communication between the hip joint and the obturator externus bursa on hip MR arthrography. Following institutional review board approval, 200 hip MR arthrograms in 196 subjects were independently reviewed by two musculoskeletal radiologists. Discrepancies were resolved by adjudication. The presence or absence of communication between ...

Articular cartilage is a heterogeneous tissue, with cell density and organization varying with depth

Regeneration of destroyed articular cartilage can be induced by transplantation of cartilage cells into a defect.

Magnetic resonance (MR) imaging plays an integral role in the assessment of articular cartilage. This article discusses the role of MR imaging in the evaluation of articular cartilage, the appearance of cartilage lesions on MR imaging, and the currently available MR imaging techniques for ...

Chondrolysis of the hip is a rare disorder, characterized by progressive and rapid destruction of articular cartilage from both joint surfaces resulting in secondary joint space narrowing and stiffness. The authors report an unusual case of chondrolysis of the hip following mini open excision of a symptomatic acetabular labral tear. ...

Cartilage matrix is damaged in diseased states such as osteoarthritis, while adult articular cartilage does not have the capacity to repair structural damage. A least invasive mean to diagnose these diseased states of human articular cartilage with a high spatial resolution is thus highly ...

Osteoarthritis (OA) is a major clinical and scientific challenge. The degradation of articular cartilage in the joints is a common manifestation of painful arthritis. The regeneration of articular cartilage in OA is an unmet clinical need. The assembly of articular ...

Because articular cartilage is avascular and has no intrinsic capacity to heal itself, physical damage to cartilage poses a serious clinical problem for orthopedic surgeons and rheumatologists. No medication exists to treat or reconstitute physical defects in articular cartilage, and ...
