We present an update of a randomized controlled trial on 71 patients (< 65 years) who received either a resurfacing hip arthroplasty (RHA) (n = 38) or cementless 28-mm metal-on-metal (MoM) total hip arthroplasty (THA) (n = 33). Metal ion levels and functional outcome scores were analyzed with a mean follow-up of 58 months (SD 8.1). No clear shifts in relatively good outcome was encountered between RHA and THA. Metal ion levels appear to equalize between groups after 3 years. Median cobalt and chromium remained below 1.3 μg/L throughout follow-up in both groups. Six revisions were performed, of which three for pseudotumor formation (one THA, two RHA). In conclusion there were no clinical differences between the two groups and metal ion levels were lower than other series remained low, however, pseudotumor formation was not eliminated.
