The economic impact of minimally invasive total hip arthroplasty.
We compared hospital length of stay (LOS) and costs between (1) minimally invasive total hip surgery (MIS) combined with an active hip pathway (AHP) and (2) long incision total hip surgery (LIS) with a passive hip pathway (PHP). A prospective consecutive cohort of 214 MIS/AHP patients was compared to a concurrent cohort of 265 LIS/PHP patients. The MIS/AHP cohort had significantly decreased LOS (1.5 days vs. 3.8 days, P < .001) and hospital costs ($12.8 thousand vs. $16.7 thousand, P < .001). The complication rates were similar for MIS/AHP and LIS/PHP. We conclude that, compared to LIS/PHP, MIS/AHP significantly shortened LOS by an average of 2.3 days, and significantly reduced hospital costs by an average of $3.9 thousand per patient.
