The present report is an update at a mean 20 years’ follow-up, addressing 2 issues: (1) implant survival at a mean 20 years; and (2) long-term complications with the metal-on-metal bearing. Twenty-eight millimeters MoM bearings show good survival at 20 years in young active subjects. Two groups of cementless hip prostheses were compared: Metasul™ 28 mm MoM versus 28 mm CoP. The MoM group comprised 30 patients (39 hips), with a mean age of 40 ± 6.7 years [range, 22.6–49 years], and the CoP group comprised 32 patients (39 hips), with a mean age of 40.5 ± 8.7 years [range, 15–50 years]. The groups were matched in 2005 for age, activity level and preoperative Harris score. At a mean 20 ± 5.3 years’ follow-up [range, 5–23 years], in the MoM group 2 hips (5%) showed limited non-progressive acetabular osteolysis, not requiring revision surgery; in the CoP group, there were 21 revision procedures (54%), including 15 for polyethylene wear. In the MoM group, the median total blood cobalt concentration was 1.03 g/L [range, 0.3–3.5] and the median chromium concentration was 1.07 g/L [range, 0.3–3.2]. Twenty-year all-cause survival was 100% in the MoM group, and 46% (95% CI, 37–59%) in the CoP group (p < 0.0001). At long-term follow-up, MoM implants showed better survival than CoP implants in a young active population. Level of evidence: III, matched case series.Show less >
