Surgical Technique: Abductor Reconstruction With Gluteus Maximus and Tensor Fascia Lata in Revision Total Hip Arthroplasty.

BACKGROUND: Abductor deficiency in revision total hip arthroplasty (THA) is a common problem that can lead to pain, limping, and instability. Repair and reconstruction of the abductors is challenging, with a high rate of failure reported in the literature. The purpose of this study is to describe a simplified technique of abductor repair augmented with the transfer of gluteus maximus (Gmax) and the tensor fascia lata (TFL). METHODS: We describe a novel abductor reconstruction with transfer of the anterior 30% of Gmax and the posterior 70% of TFL to the vastus lateralis origin. These transfers can be used in isolation or to augment repair of torn abductors to the greater trochanter. The technique is simple and quick to perform via a lateral approach, requiring dissection of only two muscle slips and minimal additional soft tissue dissection. RESULTS: We describe the use and outcomes of this technique on three patients undergoing revision THA with severe and irreparable abductor deficiency. Although these patients reported improved function after the reconstruction, there was persistence of mild to moderate limping. CONCLUSION: Abductor reconstruction with partial transfers of Gmax and TFL is a promising approach to manage abductor deficiency in revision THA. Larger series are required to determine the efficacy of this technique for restoring abductor function and improving patient reported outcomes.
