There was no evidence to demonstrate a clinically relevant difference in surgical time or shorter length of stay when comparing both groups. One moderate quality study (Boonen 2013) found no difference in hospital length of stay between both groups.
The work group recognizes that there are scenarios where patient specific instrumentation theoretically could be considered but the evidence is insufficient to make a recommendation.
