Simultaneous Acetabular Labrum Reconstruction and Remplissage of the Femoral Head-Neck Junction.

With the recent increase in the use of hip arthroscopy, revision hip arthroscopy also has become more prevalent; nevertheless, it is often complex, and many factors should be considered to achieve a satisfactory clinical outcome. Labral reconstruction or augmentation technique is used in cases of severely deficient acetabular labral tissue to restore the fluid seal mechanism. In cases of previous over-resection of cam impingement, the remplissage technique, used to restore the bony defect of the femoral head-neck junction and preserve the joint seal, is an established technique that has been recently reported in the hip with the use of iliotibial band with the same aim as in the shoulder, filling in of the defect due to healing of the soft tissue to the underlying bony impression.

Suture-on-Screw Technique for Os Acetabuli Fixation and Labral Repair.

The os acetabuli is thought to arise from unfused secondary ossification centers or as rim fractures in the setting of dysplastic hips or hips with femoroacetabular impingement. Resection of a large os acetabuli can lead to structural instability of the joint, and in these cases, osteoplasty of the impingement, reduction and internal fixation of the osseous fragment, and labral repair have been described in the literature. Anchor fixation for labral repair in the surrounding zone of the osteosynthesis might bring some technical problems.
