Determinants of patient satisfaction 5 years after dual-mobility trapeziometacarpal joint implant arthroplasty.

Of the 125 patients who underwent surgery, 108 were available for the 5 year analysis and 94 completed the satisfaction questionnaire.

Lower pain levels and higher brief MHQ scores at 5 years were significantly associated with being 'very satisfied'.

Baseline pain, brief MHQ and key pinch strength improved significantly by 5 years.

Five revision surgeries occurred, resulting in an estimated 5 year implant survival of 96% (95% CI 92 to100).
