Using ceramic heads with titanium sleeves on retained femoral stems in revision THA appears safe with no observed head-neck junction failures at mid-term, though all-cause re-revision rates vary significantly based on the indication for revision and femoral head size.

First-time revision THA for instability has a concerningly high re-revision rate within 10 years, particularly when addressing instability with modular component exchange alone or when using constrained liners.
