Objective: To report the clinical characteristics, surgical management, and medium-term outcomes of total hip replacement (THR) performed in dogs with previous contralateral pelvic limb amputation.

Animals: Thirteen client-owned dogs.

Study design: Multi-institutional retrospective clinical study.

Methods: Data recorded from medical records included signalment, indication for amputation and THR, and surgical complications. Implant positioning and complications were assessed on radiographs. Clinical outcomes were evaluated during follow-up examinations by one of the authors and through a mobility- and lifestyle-based questionnaire completed by owners.

Results: All 13 dogs had satisfactory clinical results at follow-up a median of 3 months (range, 2-36) after THR. No postoperative luxation was recorded. Four dogs had minor complications that did not require additional treatment. The only major complication was one failure of osseointegration of a cementless acetabular cup, and it was successfully revised.

Conclusion: Total hip replacement resulted in satisfactory clinical results and acceptable morbidity in this population.

Clinical significance: Total hip replacement should be considered in dogs with severe coxofemoral joint disease and contralateral pelvic limb amputation.
