“…Our findings support reports in the literature describing an association between the presence of the labral lesions and the degeneration of the adjacent articular surface, mainly proven in arthroscopy [7,14,15]. However, all of these studies have in common that they fail to provide a satisfactory explanation for the cause of articular damage.…”

“…Several theories explain the preponderance of lesions involving the anterior labral-cartilage junction. These include inferior intrinsic mechanical properties compared to other portions of the labrum or a relative hypovascularity making the anterior labrum more vulnerable to wear and degeneration because of resultant compromised remodeling and healing capacity [14,15]. However, according to our data, it is more likely chondrolabral lesions occur at the site of highest probability of femoroacetabular impact and thus are more exposed to higher mechanical stress.…”

“…The anterosuperior location of the delaminated articular cartilage and the delamination cysts correlates with the location of damage to the hip previously reported for camtype femoroacetabular impingement [18,19,21,29,33,35,45]. This region of the acetabulum is best seen on the frog lateral view of the hip and explains why the delamination cyst was seen on this view in 92% of the cases.…”

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 cartilage at the time of hip arthroscopy. We reviewed the preoperative radiographs of 125 consecutive hips that had a labral tear at hip arthroscopy for the presence of a delamination cyst. A delamination cyst was defined as an acetabular subchondral cyst either directly adjacent to a lateral acetabular cyst or in relation to a subchondral crack in the anterosuperior portion of the acetabulum. All patients with acetabular cartilage delamination at arthroscopy were identified. There were 16 patients with delamination cysts on radiographs and 15 patients with cartilage delamination at arthroscopy.

“…While acetabular labral tears have been commonly associated with acetabular dysplasia [22] or a traumatic event [29], our study as well as others [13,22] illustrate the important prevalence of abnormality of the waist of the femoral head and neck in association with labral pathology. This is especially important when one considers joint preserving procedures such as hip arthroscopy [4] and the potential to intervene in the development of hip arthritis, where tears of the labrum have long been suspected of being within the continuum leading to arthritis [2,12,24,39].…”

Femoroacetabular impingement secondary to the cam effect is thought to be associated with an insufficient anterior concavity in the sagittallaxial plane of the femoral head-neck junction. Using three-dimensional computed tomography the anterior and posterior concavity of the femoral head-neck junction was assessed in 36 painful non-dysplastic hips (30 patients). The mean age of the symptomatic hips was 40.7 with 13 females and 17 males. Eighteen out of the 36 hips had a pistol grip deformity. Magnetic resonance gadolinium arthrography was performed to assess for labral and cartilage lesions. Alpha and beta angles measuring the anterior and posterior femoral head-neck junction concavities were also determined in 20 asymptomatic hips (12 patients; mean age 37, 5 females and 7 males) using three-dimensional computed tomography. The mean alpha angle for the symptomatic and the control group were: 66.4 versus 43.8 0, = 0.001), and for the beta angle 40.2 versus 43.8 0, = 0.01 l), respectively. All but one of the symptomatic hips had a labral tear with 61% of these hips having associated cartilage damage. Three-dimensional computed tomography represents an accurate tool to quantify the femoral head-neck concavity providing a non-invasive assessment of hips at risk of femoroacetabular impingement.
