Objectives: The disruption of the abductor muscles of the hip after hip revision surgery, often causes limping, pain and instability of the implant. The purpose of our work is to describe a mesh technique to repair hip abductor mechanism injuries after hip revision.

Methods: Forty-six patients with hip abductor damage after prosthetic revision were treated. All patients presented prosthetic loosening, complained of pain, and had Trendelenburg sign positive, due to deficient abductor muscle mechanisms. Thirty-one were women (67.39%). The average age was 64 years old (34-82). The number of previous revision surgeries was 3 (2-7). The Merle d ' Aubigne' Score and variants before and after treatment were also reported.

Results and Conclusion: In the postoperative follow-up after hip revision with the mesh technique the Merle d' Aubigné score improved postoperatively and the Trendelenburg sign was negative in 78.3% of the patients (p<0.001). Also, the Trendelenburg test with the knee flexed was negative in 60.9% (p<0.001) and stair-climbing test was negative in 60.9% of cases (p<0.001). The gluteus medius test in lateral position was negative in 52.2% of patients, and in lateral position with the knee flexed was negative in 47.8% of patients (p<0.001). Conclusion: Repair of the abductor mechanism with the mesh technique has proven effective for both partial and total lesions.
