Objective The purpose of this study was to examine differences in self-reported physical functioning via the Modified Disablement in the Physically Active Scale (mDPA) and single-leg hop limb symmetry index (LSI) between individuals with a history of anterior cruciate ligament reconstruction (ACLR) and SRC compared to an ACLR group without history of SRC. Methods Forty participants [24 female; mean age = 24.3 +/− 4.1 years; height (cm) = 169.9 (SD = 9.1); weight (kg) = 73.2 (SD = 15.1)] with a history of ACLR (≥1-year post-operative) were separated into a SRC history group (SRC; n = 11) and no SRC history group (NO SRC; n = 29). Participants completed the mDPA physical summary component (mDPA-PSC) and hop testing (single-leg hop, crossover-hop, and triple-hop all for distance). SRC history was self-reported as yes/no and LSI was calculated using the equation: (mean distance involved limb/mean distance uninvolved limb) x 100. Mann–Whitney U tests (p Results The SRC history group reported worse physical functioning on the mDPA-PSC compared to the no SRC history group [SRC = 10 (IQR = 13), NO SRC = 5 (IQR = 10), p = 0.02, ES = -0.79, 95%CI = -1.49 to −0.08]. No statistical differences were observed for the single-leg hop or triple-hop, but the SRC history group performed worse on the crossover-hop [SRC = 0.96 (IQR = 0.07), NO SRC = 1.02 (IQR = 0.10), p = 0.006, ES = 0.74, 95%CI = 0.03–1.43]. Conclusions These results suggest that SRC history may negatively influence subjective evaluation of physical functioning and objective lower-extremity functional performance in patients after ACLR.
