“…Strategies of treating labral tears continue to evolve with our understanding of labrum physiology and function. Recent studies imply that the labrum performs an important role in hip stability and decreasing contact stresses across the hip joint [5–8]. The biomechanical case for labral preservation can be made, and outcomes studies are beginning to suggest the same [9–11].…”

The purpose of this article is to determine normative values for the length of the acetabular rim and detect differences between gender, age, ethnicity, height and leg length. Six measurements were taken on the acetabular rim of 143 cadaveric skeleton specimens (286 acetabula) using a coordinate-measuring device: circumferential (excluding acetabular notch), anterior inferior iliac spine (AIIS)-anterior, AIIS-posterior, 12–3 o’clock, 12–9 o’clock and 11–5 o’clock. Museum specimen height data and leg length data from a previous study were recorded for 109 of 143 specimens. Intraclass correlation coefficients were calculated. Student t-tests compared mean values. Multiple regression analysis was used to determine the relationship between acetabular rim length and gender, age, ethnicity, height and leg length. The average acetabular rim length in males for circumferential, AIIS-anterior, AIIS-posterior, 12–3, 12–9 and 11–5 o’clock were 15.8, 4.2, 11.7, 4.9, 4.7 and 9.5 cm, respectively; and for females: 13.7, 3.7, 10.0, 4.3, 4.1 and 8.3 cm, respectively. Intraclass correlation coefficients were 0.953, 0.930, 0.958, 0.857, 0.913 and 0.951, respectively, for each measurement. All six measurements were significantly larger for males (P < 0.001). Multiple regression analysis demonstrated a significant relationship between gender and rim length for all six measurements (P < 0.001) and between height and leg length and acetabular rim length for five of the six measurements exclusive of AIIS-anterior (P < 0.001). No significant trends between age or ethnicity and rim length were found. Average acetabular rim lengths were established. The acetabular rim is significantly longer in males and correlates with height and leg length. Age and ethnicity do not appear to be significant predictors of acetabular rim length. Normative values for acetabular rim lengths may assist in hip preservation surgery.

“…15 In a previous study, ITB, gracilis, anterior tibialis, and semitendinosus autografts were found to have similar biomechanical properties to the native labrum. 16 However, there is a lack of literature on the intrinsic biomechanical characteristics of commonly used allografts 17 or the surrounding soft tissues (indirect head of rectus femoris and capsule) when used for labral restoration techniques. At our institution, ITB autografts have been used for labral reconstruction with good results at short-term and midterm follow-up.…”

The importance of the acetabular labrum has been well documented for the function and overall health of the hip joint. Several biomechanical studies have shown the sealing effect of the acetabular labrum. In the past decade, labral repair procedures have gained increased attention, with the literature suggesting that the outcomes after hip arthroscopy are directly related to labral preservation. However, a primary labral repair can be challenging in cases of hypoplastic, ossified, or complex and irreparable labral tears in which there is insufficient tissue to perform a primary repair. For these cases, labral reconstruction becomes a viable option with good outcomes at short-term and midterm follow-up. A subset of these patients may show viable remnants of the labral circumferential fibers but, because of the low tissue volume, these remnant fibers are unable to maintain the suction seal. In this situation, a labral augmentation may be a viable alternative to labral reconstruction while preserving as much native labral tissue as possible. The purpose of this Technical Note is to describe an arthroscopic hip labral augmentation technique using iliotibial band autograft or allograft.

“…11 Nepple and colleagues 8 reported a significant increase in hip distractive stability with a partial labral resection state as compared with labral reconstruction. Furthermore, recently published cadaveric biomechanical studies have reported improvements in the joint contact area, intra-articular pressures, 12 and pressurization with both labral repairs and labral reconstructions. 5 Likewise, good results have been reported for labrum reconstruction using ligamentum teres capitis or fascia lata autograft in patients undergoing open surgical hip dislocation.…”

The dynamic function of the acetabular labrum makes it an important structure for both hip stability and motion. Because of this, injuries to the labrum can cause significant dysfunction, leading to altered hip kinematics. Labral repair is the gold standard for symptomatic labral tears to keep as much labral tissue as possible; however, in cases where the labrum has been injured to such a degree that it is either deficient or repair is not possible, arthroscopic labral reconstruction is preferred. This article describes our preferred approach for reconstruction of the acetabular labrum using iliotibial band autograft.

Labral Reconstruction With Iliotibial Band Autografts and Semitendinosus Allografts Improves Hip Joint Contact Area and Contact Pressure

Abstract: Labral reconstruction appears to improve femoroacetabular joint biomechanics as compared with the labrum-resected state; these improved biomechanics may translate into increased joint function clinically.
