December 2020 Sports Medicine Journal Roundup

This month we bring you all of the sports medicine literature from around the world and summarize it here on the sports medicine review.

The American Journal of Sports Medicine (DEC 2020)

  • A majority of patients achieved minimal clinically important difference (MCID) by 6 months after surgery.
  • Dominant-sided surgery and concomitant distal clavicle excision resulted in faster clinically significant outcomes (CSO) achievement, while workers’ compensation status, concomitant biceps tenodesis, current smoking, partial-thickness rotator cuff tears, and higher preoperative PROMs resulted in delayed CSO achievement.
  • This study provides clinical evidence from patients who underwent ACLR and from complementary modeling that functional postoperative knee mechanics are sensitive to graft tunnel locations and graft angle.
  • Of the factors studied, the sagittal angle of the ACL was particularly influential on knee mechanics.
  • Revision surgery for medial patellofemoral ligament reconstruction (MPFLR) failure, including the correction of major anatomic risk factors, yielded a significant improvement in patient-reported quality-of-life outcome measures.
  • Patients with failed MPFLR, however, were significantly more restricted before revision surgery than patients without previous interventions when evaluated with the BPII 2.0.
  • Chronic sesamoid pain is difficult to treat, but this study confirms that with a meticulous surgical technique and a dedicated postoperative rehabilitation program, encouraging patient-reported outcomes can be expected with a minimal risk of complications.
  • Moreover, in the current study, 80% of competitive athletes were able to return to sports at a mean of 4.62 months after surgery.

British Journal of Sports Medicine (DEC 2020)

  • Physiotherapist-led interventions might improve pain and function in young and middle-aged adults with hip-related pain, however full-scale high-quality RCT studies are required.
  • Based on empirical evidence, we provide a call to re-evaluate clinical guidelines related to medical disorders that have previously been considered contraindications to prenatal exercise.
  • Removing barriers to physical activity during pregnancy for women with certain medical conditions may in fact be beneficial for maternal–fetal health outcomes.
  • We found favourable associations for most health-related outcomes with high occupational physical activity (OPA) levels, but we also found some evidence for unfavourable associations due to high OPA levels.
  • At this point, there is a need for better quality evidence to provide a unequivocal statement on the health effects of OPA.
  • Increasing physical activity in the population would lead to reduction in working-age mortality and morbidity and an increase in productivity, particularly through lower presenteeism, leading to substantial economic gains for the global economy.

Sports Medicine (DEC 2020)

  • Active commuting defined as walking, cycling
  • Active commuting decreases mainly all-cause and cardiovascular mortality, with a dose–response relationship, especially for walking.
  • Preventive strategies should focus on the benefits of active commuting.
  • Plyometric jump training (PJT) is effective in improving jumping and sprinting performance among young male soccer players.

Sports Health Journal (DEC 2020)

  • Most studies centered around the football athlete, either professional or collegiate.
  • Professional football game day use of intramuscular ketorolac declined from 93.3% in 2002 to 48% in 2016.
  • Collegiate football game day use of intramuscular ketorolac declined from 62% in 2008 to 26% in 2016.
  • Game day corticosteroid injection was far lower than ketorolac usage.
  • Both medications were reported to be effective with few adverse events.
  • A total of 340 participants were included and the mean LSI (limb symmetry index was >95% for each single leg hop test (SLHT).
  • When analyzed as a test battery, only 45% of participants achieved this standard. Significantly weak to moderate correlations existed among hop tests
  • Participant performance across all SLHT components varied, such that less than half of healthy athletes could achieve ≥90% LSI across all hops.
  • Current guidelines require ≥90% LSI on SLHTs.
  • The majority of healthy youth athletes could not achieve this standard, which questions the validity of this LSI threshold in youth athletes after ACLR.

Current Sports Medicine Reports (DEC 2020)

Journal of Science and Medicine in Sport (DEC 2020)

  • This study provides a novel and current insight of the incidence and details of HNF injuries among cricket participants in Victoria over a decade.
  • It is evident that males and younger participants, regardless of gender, have a higher risk of sustaining a HNF injury.
  • This study provides a solid evidence base for stakeholders in developing strategies to minimise head, neck and facial injuries to make cricket a safe sport for all.
  • We validated the HR index (HRindex)/ VO2 relationship in professional soccer players.
  • HR Index = activity/ sporting HR / resting HR
  • HRindex showed better agreement with metabolism than actual HR and similar agreement to the other HR parameters.
  • HRindex allowed to estimate VO2, but at very high-intensity HRindex underestimated VO2.
  • Future studies should test this in real game conditions.
  • HRindex could offer a time-efficient and easy-to-use “field” method to monitor aerobic metabolism in soccer.
