Objective: Techniques for the revision of total hip arthroplasties are usually complex, and surgeons may need to chose from among several options during such surgery. Here we report the short-term outcomes of revision surgeries involving such techniques.
Methods: We reviewed 14 hips in 13 patients (mean age 67 years, range 52-78 years) followed over a mean period of three years (0.5-6.0 years). Acetabular revision surgery involved cementless cup placement in three hips or impaction bone grafting with cement in seven hips. Femoral revision surgery involved the cement-in-cement technique in three hips, impaction bone grafting with cement in nine hips, and allograft-prosthesis composite use in one hip.
Results: No femoral stems required re-revision. Re-revision was required for only one acetabular cup using impaction bone grafting with cement for aseptic loosening and a metal mesh should be placed due to a thin acetabular medial wall.
Conclusion: Techniques for revision of total hip arthroplasties must be selected accounting for the extent of bone deficiency on an individualized basis.
