One-stage complete eradication and revision hip due to pseudotumor in metal-on-metal hip arthroplasty.

The one-stage strategy of radical excision and revision with non-MOM couplings in pseudotumors due to MOM hip arthroplasty achieved good 3-year outcomes. However, complications were frequent (23%). Recurrences were not rare (14%) and did not require implant re-revision.
