LETTER TO THE EDITOR REGARDING "HEALTH ECONOMIC EVALUATION OF MICROPROCESSOR AND NON-MICROPROCESSOR-CONTROLLED PROSTHETIC KNEES"

This Letter to the Editor responds to the article by Bosman et al. ( https://doi.org/10.33137/cpoj.v8i2.45823 ). Real-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 (€457,063) 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 €19,603 per QALY, consistent with accepted health technology assessment thresholds.
