Fig 2.

(A) Arthroscopic view of the central compartment of the right hip with the 70° arthroscope inserted through the mid-trochanteric portal, aimed at the pulvinar. The ligamentum teres (LT) stump (black asterisk) is seen, indicating complete tear. (B) Anteroposterior fluoroscopic image of the right hip showing drilling of the femoral tunnel. The white asterisk denotes a 5.0-mm cannulated reamer, exiting at the level of the fovea. (C) Anteroposterior fluoroscopic view of the right hip showing proper placement of an all-suture anchor (2.3 mm Iconix, No. 5 ultrastrength wire; Stryker) in the cotyloid fossa. The inserter must breach the pelvic brim by approximately 6 to 8 mm to allow for intrapelvic placement of the all-suture anchor, with aperture fixation against the strong medial wall cortical bone (yellow arrow). The previously drilled femoral head tunnel is visible (black asterisk) with the two black arrows delineating the point of entry at the femoral head-neck junction and exit at the fovea. (D) Arthroscopic view of the peripheral compartment of the right hip with the 70° arthroscope inserted through the mid-trochanteric portal, visualizing the anterior femoral head-neck junction. The ligamentum teres graft (black asterisk) may be seen during passage into the femoral tunnel. (E) Arthroscopic view of the peripheral compartment of the right hip with the 70° arthroscope inserted through the mid-trochanteric portal, visualizing the anterior femoral head-neck junction. A 4.75-mm biotenodesis screw (Arthrex) is seen advancing over a guidewire to secure the ligamentum teres graft distally within the femoral tunnel. The hip is positioned in extension and external rotation during distal graft fixation. (F) Arthroscopic view of the central compartment of the right hip with the 70° arthroscope inserted through the mid-trochanteric portal, visualizing the contents of the pulvinar. The new ligamentum teres graft is seen in anatomic position with good tension. (FH, femoral head; HNJ, head neck junction.)
