Introduction:
We present a case report of a total hip arthroplasty (THA) in a patient with ipsilateral knee arthrodesis. The direct anterior approach (DAA) was used, and to our knowledge, this has never been described previously in the literature. The purpose of this report is to highlight pre-, per-, and post-operative challenges using the DAA in these rare cases.
Case Report:
This case report presents the case of a 77 year old female patient with degenerative hip disease in the presence of an ipsilateral arthrodesis of the knee. The patient was operated using the DAA. No complications were found and the patient had an excellent follow-up with a forgotten joint score of 93.75 at 1 year. The difficulty in this case consists in finding the correct stem anteversion with the altered knee anatomy. Using pre-operative templating on X-rays, intraoperative fluoroscopy and the posterior femoral neck the hip biomechanics could be restored.
Conclusion:
We believe that THA in presence of an ipsilateral knee arthrodesis can be safely performed through a DAA.
