The literature article entitled, "preliminary report of clinical experience with metal-on-highly-crosslinked polyethylene hip resurfacing" written by r.B.C.Treacy, j.P.Holland, j.Daniel, h.Ziaee, and d.J.W.Mcminn published by bone and joint research october 2019 was reviewed.The article's purpose was to report early performance of hra (hip resurfacing arthroplasty) using a direct-to-bone cementless mono-block xlpe component (non de-puy) with a cobalt-chrome femoral head (non-depuy).The article's focus is on non-depuy component performances.However, the article mentions one of the cases includes a revision case where the non-depuy components replaced a failed depuy asr hra and the reason for revision was for adverse reaction to metal debris.This complaint captures this one revision case.Figure 7a provides radiographic image of the asr component that was revised to a non-depuy product (7b and 7c) in a (b)(6) year old very active male patient.Depuy products: asr head, asr cup.Adverse event: revision for armd (attributed to bearing wear).
