AI Article Synopsis
- Secondary hip osteoarthritis with acetabular bone defects is a complex issue in hip replacement surgeries, with a revision rate of about 10% to 15% over a decade.
- A 54-year-old woman who had total hip arthroplasty (THA) 10 years prior due to a bone defect experienced loosening and dislocation of her prosthesis, prompting a revision surgery that successfully used a cementless acetabular cup.
- This case highlights the importance of using bone grafts during initial THA, as it showed significant bone healing and formation at the acetabulum after a decade, leading to improved outcomes.
Article Abstract
Background: Secondary hip osteoarthritis with acetabular bone defect is still a challenging case in hip arthroplasty surgery. The incidence of revision total hip arthroplasty is estimated to be between 10% and 15% in 10 years. Simple revision cementless acetabular cup after a prior complex cemented-THA rarely performed.
Case Presentation: A case of aseptic loosening with prosthesis dislocation after THA was reported in a 54 year-old female patient. The patient had prior surgery of THA 10 years ago due to secondary post-traumatic hip osteoarthritis with acetabular bone defect. At the first surgery, cemented acetabular cup with acetabular bone grafting was performed to fill the defect. A complete new acetabulum bone formation was encountered at 10 years after the surgery which lead to simple revision THA with primary cementless acetabular cup. Excellent functional outcome was also reported at the final follow-up after revision THA.
Conclusion: This case showed that the potential of bone healing of the acetabulum cannot be underestimated. Therefore, it is suggested to always put an adequate bone graft to manage acetabular bone defect in THA surgery and a new acetabulum bone formation can be expected.
