  • These findings suggest that partial tears introduce a spectrum of instability from functionally intact to completely torn.

  • As a result, some may be biomechanically amenable to nonoperative treatment, while others would be indicated for early reconstruction.

  • Further research into the biological and biomechanical determinants of nonoperative treatment failure will assist with more precise treatment recommendations.

  • Anchor repair demonstrated a significant decrease in rerupture rate when compared with transosseous repair.

  • There was no difference in reoperation rate, infection rate, or time to release from medical care.

  • Intra-articular use of APS for mild to moderate knee OA was safe, and significant pain improvement was documented 3 years after a single injection.

  • Patients with better cartilage status seem to respond better than patients with more cartilage loss, with more clinical improvement even when starting from more painful conditions.

  • Patients required a minimal number of opioids after knee arthroscopic surgery with partial meniscectomy.

  • There was no difference in the number of tablets utilized whether the opioid prescription was included in a multimodal pain control regimen or patients were given an option to fill the prescription.

  • Offering optional opioid prescriptions in the setting of a multimodal approach to pain control can significantly reduce the number of unused opioids circulating in the community.

  • Pericapsular injection provides equivalent analgesia when compared with lumbar plexus blockade.

  • It is a safe intervention that allows for efficient postoperative analgesia for patients undergoing hip arthroscopy.

  • Functional rehabilitation with early weightbearing is a safe alternative to traditional immobilizing treatment for ATR, giving better early functional outcomes, albeit with a higher incidence of transient minor skin complications

  • Lumbar pars defects were a common cause of low back pain in American professional baseball players.

  • The vast majority of affected athletes were able to return to competition without demonstrating a significant decline in baseball performance.

  • Of the currently available imaging modalities, MRA provides the best combination of sensitivity and specificity of the evaluation of the UCL. Further research comparing ultrasound with MRA is needed.

  • Intra-articular injection of culture-expanded MSCs without adjuvant surgery can improve pain for patients experiencing knee osteoarthritis at short-term follow-up (6-12 months).

  • However, evidence regarding function and cartilage repair remains limited.

  • Preseason screening of shoulder external rotation ROM may identify professional baseball pitchers and swimmers at risk of injury.

  • Shoulder ROM screening may not be effective to identify handball, softball, volleyball and tennis players at risk of injuries.

  • The results of this systematic review and meta-analysis should be interpreted with caution due to the limited number of studies and their high degree of heterogeneity.

  • The Knee Control injury prevention programme reduced acute injuries in youth floorball players; there was no effect on overuse injuries.

  • Participating in an exercise intervention increased the relative risk of non-serious adverse events, but not of serious adverse events. Exercise therapy may therefore be recommended as a relatively safe intervention.

  • Older age and a history of HSI are the strongest risk factors for HSI.

  • Future research may be directed towards exploring the interaction of risk factors and how these relationships fluctuate over time given the occurrence of index and recurrent HSI in sport is multifactorial.

  • In women’s football, there is low-level evidence that multicomponent, exercise-based programmes reduce overall and ACL injuries by 27% and 45%, respectively.

  • Findings from the review suggest a higher risk of lung cancer among men reporting high-level occupational physical activity.

  • Further prospective studies incorporating rigorous measures of domain-specific physical activity, detailed smoking status and intensity, and other occupational exposures are needed to elucidate this association.

  • We found limited scientific evidence to support exercise-based strategies to prevent muscle injury in elite footballers.

  • Intrinsic factors, previous injury, range of motion (lack or excess), and rotator cuff weakness (isometric and isokinetic) highly increase the risk of future injuries.

  • Years of athletic practice, body mass index, sex, age, and level of play seem to have modest influence.

  • As for the effect of scapular dysfunction on shoulder injuries, it is still controversial, though these are typically linked.

  • Extrinsic factors, field position, condition of practice (match/training), time of season, and training load also have influence on the occurrence of shoulder injuries.

  • There was no significant difference in ER after throwing at underloaded weights. The overload condition showed a statistically significant increase of 3.3° in external rotation. The extreme overload condition showed a statistically significant increase in ER of 8.4°. There were no differences in internal rotation for any group.

  • A significant increase in shoulder ER was observed immediately after throwing overload weighted balls. This effect increased as the weights of the balls increased.

  • The handgrip test and vertical jump were associated with midshaft tibia speed of sound (T-SoS) in boys and girls independent of sport status. These results suggest that physical fitness is associated with bone health in adolescents, particularly boys, and that the relationship between physical fitness and bone may differ depending on sex and athletic status.

  • Low intensity hand grip exercises (LI-IHE) seem to lower SBP, DBP, and MAP values in prehypertensive and hypertensive adults. It appears that LI-IHE reduces, in greater magnitude, blood pressure levels in hypertensive patients, specifically in patients aged <45 years, those who are overweight, and those on medications.

  • Substantial heterogeneity in the main results and in the analyses by subgroups generated uncertainty about the real reduction magnitude that LI-IHE can produce on blood pressure.
