( https:\/\/doi.org\/10.33137\/cpoj.v8i2.45823  ).\nReal-world Dutch resource use data from Bosman et al. demonstrated lower non-prosthesis healthcare costs for microprocessor-controlled knee users compared with non-microprocessor-controlled knees, although the reported incremental cost per QALY (\u20ac457,063) appears unexpectedly high. This estimate likely overstates cost per QALY because prosthesis-related expenses were inconsistently prorated and implicitly assumed a 6-month replacement cycle, which is not clinically plausible. Recalculation assuming a conservative 5-year prosthesis replacement cycle resulted in an ICUR of \u20ac19,603 per QALY, consistent with accepted health technology assessment thresholds.\nArticle PDF Link: https:\/\/jps.library.utoronto.ca\/index.php\/cpoj\/article\/view\/46339\/34632\nHow To Cite: Br\u00fcggenj\u00fcrgen B, Riemer A, Gapp M.
