20 UCL injuries in 177,000 athlete exposures
Incidence 1.12 / 10,000 AE
85% during throwing, 71% late (4th inning or later)
MLB players spent 117 days on DL, minor league 93.9
Rates of subsequent injuries (shoulder, elbow, forearm) significantly higher in both leagues
26 (19.4%) MLB and 56 (8.9%) minor league players required an UCL reconstruction
Passive knee extension range of motion (hazard ratio [HR], 0.97 [95% CI, 0.95-0.99]; P = .008) and ankle dorsiflexion range of motion (HR, 0.93 [95% CI, 0.88-0.99]; P = .02) were independently associated with the injury risk.
Among recreational runners, women sustain injuries at a higher rate than men
Greater knee stiffness, more common in runners with higher body weights (≥80 kg), significantly increases the odds of sustaining an overuse running injury
Contrary to several long-held beliefs, flexibility, arch height, quadriceps angle, rearfoot motion, lower extremity strength, weekly mileage, footwear, and previous injury are not significant etiologic factors across all overuse running injuries.
Overall clinical incidence for all sports was 1.9 (95% CI, 1.8-2.0) for male sports and 1.5 (95% CI, 1.4-1.6) for female sports.
Female athletes were at a 1.9 (95% CI, 1.8-2.2) times greater risk for enduring SRCs than male athletes in sex-comparable sports, with a greater risk in baseball/softball (RR, 2.7 [95% CI, 1.9-3.8]), basketball (RR, 2.5 [95% CI, 2.1-2.9]), and soccer (RR, 1.6 [95% CI, 1.4-1.9]).
Female student-athletes had significantly longer time loss than male student-athletes ( P < .001).
The mean number of missed school days did not differ between sexes ( P = .70).
British Journal of Sports Medicine (July 2018)
Psychological interventions demonstrate small (0.2) to large (1.21) effects on sports injury rates.
The research area demonstrates a cumulative moderate risk in reporting bias (52%).
Limited to moderate evidence that one in four athletes did not return to their previous level of sport participation after surgery for FAI syndrome.
Only 37% of the included studies clearly distinguished RTS from RTS-PRE.
Thus, if a player asks a surgeon ‘Will I get back to my previous level of performance?’ there are presently little to no published data from which to base an answer.
Sports Medicine (July 2018)
“based on the empirical evidence currently available, active cool-downs are largely ineffective for improving most psychophysiological markers of post-exercise recovery, but may nevertheless offer some benefits compared with a passive cool-down”
A great majority of patients RTS and RTW after THA within a timeframe of 28 and 17 weeks, respectively
Sports Health (July 2018)
Physicians have changed their preferred techniques for ACLR, anterior shoulder stabilization, and PCL reconstruction.
Physicians have also become more conservative with pregame Toradol injections.
Clinical Journal of Sports Medicine (July 2018)
“All 15 injuries were identified on MRI and CEUS, whereas 10 injuries showed abnormalities in conventional ultrasound. “
“Because the number and quality of studies was low, the effects of marijuana on athletic performance remain unclear.”
