Goldring et al. retrieved the bone-cement interface membrane from 20 patients undergoing revision THA for aseptic loosening. The study asked whether this tissue was inert fibrous scar or a biologically active structure driving progressive bone resorption. Histology, histochemistry, cell culture, and organ culture were used to characterize the membrane and quantify its production of PGE2 and collagenase.
For over 20 years before this paper, surgeons discarded the bone-cement interface membrane as unremarkable fibrous tissue and attributed loosening to purely mechanical failure.
Goldring's 1983 study proved the membrane is the driver, not a bystander. It produces PGE2 and collagenase at levels approaching rheumatoid synovium — both potent bone-resorbing agents. Which is why aseptic loosening progresses even after the initial mechanical event.
When you see a progressive radiolucent zone on serial radiographs after THA, you are watching a biologically active membrane at work. Waiting risks compounding bone loss that will complicate revision. This paper underpins the argument for early revision before extensive osteolysis occurs.
This work directly enabled subsequent identification of IL-1, IL-6, TNF, and NALP3 inflammasome activation as additional mediators of particle disease. All downstream consequences of wear debris overwhelming local clearance mechanisms, a concept Goldring et al. Were among the first to articulate.
