Do runners with anatomical quirks get more injuries than symmetrical and aligned runners? This study was another attempt to settle an old question that just won’t die.
It was the right kind of study (prospective), but perhaps a bit underpowered with only 89 subjects and just 12 weeks of monitoring for new injuries. I wish I could see the same data for a couple hundred runners over six months. Subtle vulnerabilities might take quite a while to crop up, particularly in runners who have already gotten through at least six months without any injury. Still, 24 of these runners did get injured in those twelve weeks — which is a lot! — and “we did not find significant associations between lower limb length discrepancy, Q-angle, subtalar angle and plantar arch index and injury occurrence.”
Surprise surprise. And so, as we’ve known for years, either there’s no relationship between running injuries and anatomical imperfections at all … or it’s too subtle to detect easily, in which case who really cares? These things are mostly impossible to fix anyway.

There is conflicting evidence on the association between lower limb alignment characteristics and the incidence of running-related injury (RRI). Therefore, the primary aim of this study was to investigate the association between lower limb alignment characteristics and the incidence proportion of running-related injury in a convenience sample of recreational runners. A total of 89 recreational runners were included in this prospective cohort study. These participants had been running for at least six months and were injury-free at baseline. Lower limb alignment measurements were conducted in order to calculate lower limb discrepancy, Q-angle, subtalar angle and plantar index. All participants also answered a baseline and biweekly online surveys about their running routine, history of RRI and newly developed RRI over a period of 12 weeks. The prevalence of previous RRI and the 12-week incidence proportion of new RRI were calculated. Logistic regression analysis was performed to estimate the association between lower limb length discrepancy, Q-angle, subtalar angle and plantar ach index with the incidence proportion of RRI. The prevalence of previous RRI was 55.1% (n = 49). The 12-week incidence proportion of new RRI was 27.0% (n = 24). Muscle injuries and tendinopathies were the main types of RRI identified. The lower leg and the knee were the main anatomical regions affected. We did not find significant associations between lower limb length discrepancy, Q-angle, subtalar angle and plantar arch index and injury occurrence.
