“…Hip RoM in the sagittal plane was reduced in almost all studies compared to healthy controls (Beaulieu et al, 2010;Bennett et al, 2008;Foucher et al, 2007;Kiss and Illyes, 2012;Madsen et al, 2004;Perron et al, 2000;Varin et al, 2013) as well as compared to the nonoperated limb (Benedetti et al, 2010;Kiss and Illyes, 2012). Peak hip extension was consistently reduced compared to controls (Beaulieu et al, 2010;Bennett et al, 2008;Perron et al, 2000;Sander et al, 2011;Tanaka, 1998;Varin et al, 2013). Peak hip flexion was most often similar to controls (Bennett et al, 2008;Kiss and Illyes, 2012;Tanaka, 1998;Tateuchi et al, 2011), but was reduced in some studies (Beaulieu et al, 2010;Kiss and Illyes, 2012 (anterolateral group)).…”
