Abstract

PURPOSE: Adverse local soft tissue reactions can occur in response to wear debris or corrosion products released from total hip arthroplasty (THA). Hip arthroscopy is a useful diagnostic adjunct in the investigation of painful THA.

METHODS: A patient with a painful primary metal-on-highly cross-linked polyethylene THA underwent hip arthroscopy to confirm the diagnosis of trunnion corrosion.

RESULTS: The prosthetic implants were well fixed and aligned with no indication of infection. Hip arthroscopy was used to confirm the presence of corrosion on the trunnion of a titanium stem at its junction with a cobalt-chrome head. Due to persistent symptoms, the patient subsequently underwent arthrotomy, which confirmed the diagnosis, and revision hip arthroplasty to a titanium adapter sleeve, ceramic head and liner exchange, with relief of his symptoms.

CONCLUSION: Hip arthroscopy may prove a useful additional diagnostic tool in the investigation of this emerging clinical entity. LEVEL OF EVIDENCE: IV.
