Plain-English summary
A 12-month-old Golden Retriever was brought in after her hip replacement surgery failed due to loosening of the prosthesis, which happened six months after the operation. The dog had been diagnosed with hip arthritis caused by hip dysplasia before the surgery. When the prosthesis was removed, tests showed inflammation and tiny particles made of metals like cobalt and chromium, likely from the worn-out implant. This situation raises concerns about potential health issues in dogs with hip replacements, similar to those seen in humans.

Abstract
A 12-month-old Golden Retriever bitch underwent unilateral hip arthroplasty following a diagnosis of coxofemoral osteoarthritis secondary to hip dysplasia. The hip prosthesis underwent aseptic loosening and was removed 6 months after implantation. Synovial biopsies taken at that time revealed scattered foci of granulomatous inflammation associated with intra-cytoplasmic and extracellular particulate material. Electron microscopical analyses demonstrated that this material contained cobalt, chromium, titanium and zirconium, which was probably wear debris from the loosened prosthesis. In human patients with hip arthroplasty, widespread dissemination of wear debris from loosened prostheses occasionally occurs, with an increased prevalence of neoplasia. A similar phenomenon may be predicted to occur with the increasing use of hip arthroplasty in the dog.
