Three high quality studies (Goosen et al 2011, Repantis et al 2015, and Taunton et al 2014) examined the three most common total hip approaches. Though well designed individually, they did not compare all of the common approaches in each paper. Therefore, the strength of the recommendation was downgraded to moderate.
