Case report:

46-year-old female who claimed right inguinal pain for about one month, with functional limitation of the extremity and pain during the external rotation of the right hip, C-sign positive, with no radiographic signs of coxofemoral impingement, with articular space conservated; a hip arthroresonance was performed, with the preoperative diagnosis of complete anterosuperior acetabular labral tear Czerny and Hoffman stage IIIa.

Objective:

To share the value and precision that we have for the diagnosis and the treatment of the acetabular labral tears with arthroscopic management.

Results:

A diagnostic and therapeutic right hip arthroscopy was done, with the finding of synovitis of the acetabular rim, an anterosuperior acetabular labrum protrusion, with no detachment; during the hip manipulation there was no impingement with the femoral head. Synovectomy and acetabular labral tear repair was done by debridement and thermoplasty of the lesion, with posterior follow-up.

Conclusions:

We do not find concordance between the stadification of the acetabular labral tear by hip arthroresonance and the arthroscopic findings. We must be cautious when establishing a preoperative diagnosis based on clinical and imaging data.
