Survivorship and relative risk of revision in computer-navigated versus conventional total knee replacement at 8-year follow-up.

abstract：:Background and purpose - Radiostereometric analysis (RSA) is the gold standard to study micromotion of joint replacements. RSA requires the acquisition of additional radiographs increasing the radiation dose of patients included in RSA studies. It is important to keep this dose as low as possible. Effective radiation ...
