march 2021 sports medicine journal roundup review


This month, we review all of March’s Sports Medicine Journals all in one place here on the sports medicine review.
  • Needle aspiration of calcific deposits (NACD) +PRP resulted in worse clinical scores at the 6-week follow-up but better clinical scores at the 6-month follow-up compared with NACD +corticosteroids.
  • At the 1- and 2-year follow-ups, the results were comparable between groups.
  • Furthermore, PRP seemed to reduce the need for additional treatments but was associated with more complications.
  • In conclusion, NACD +corticosteroids had a favorable early effect on pain and function combined with low comorbidity. Thus, it remains the treatment of choice for patients with RCCT.
  • There was a statistically significant reduction in apprehension after patellofemoral stabilization in the majority of patients.
  • Patients graded their apprehension symptoms significantly higher in both quantity and quality than the surgeon. Persistent patellar apprehension after stabilization was correlated with lower quality-of-life scores.
  • No relationship could be found between persistent apprehension and patellofemoral risk factors.
  • These results suggest that use of the apprehension tests as an outcome is inappropriate until further validation is performed.
  • Less than one-fifth of NCAA athletes surveyed specialized before age 15 years, and neither scholarship attainment nor time-loss injury rate was affected by early specialization.
  • Early specialization is on the rise but is associated with increased burnout.
  • For rehabilitation after ACLR, progressive eccentric cycle training was not more clinically effective than concentric training at a matched perceived intensity dose in male patients. 
  • This can guide exercise prescription for reducing gait and strength deviations of these patients.
  • Patients who underwent open and endoscopic repairs for chronic partial- and full-thickness proximal hamstring tendon tears reported high PROs and satisfaction at a minimum 2-year follow-up with low rates of complications.
  • Despite the frequent occurrence of radiographic changes, long-term functional outcome after Rockwood I and II acromioclavicular joint injuries is good, with only clinically nonrelevant functional differences between the injured and contralateral shoulders.

  • For midportion Achilles tendinopathy, wait-and-see is not recommended as all active treatments seemed superior at 3-month follow-up.
  • There seems to be no clinically relevant difference in effectiveness between different active treatments at either 3-month or 12-month follow-up.
  • As exercise therapy is easy to prescribe, can be of low cost and has few harms, clinicians could consider starting treatment with a calf-muscle exercise program.
  • Evidence suggests that IA hip saline injections performed as well as all other injectable options in the management of hip pain and functional outcomes.
  • This predictive model using only baseline data identified athletes and cadets who would go on to sustain sport-related concussion with comparable accuracy to many existing concussion assessment tools for identifying concussion.
  • Furthermore, this study provides insight into potential concussion risk and protective factors.
  • Because of inconsistent evidence among studies, grade B evidence exists to support the use of NMES to aid in the recovery of quadriceps strength after knee surgery.
  • Based on the parameters utilized by studies demonstrating optimal treatment effects, it is recommended to implement NMES treatment during the first 2 postoperative weeks at a frequency of ≥50 Hz, at maximum tolerable intensity, with a biphasic current, with large electrodes and a duty cycle ratio of 1:2 to 1:3 (2- to 3-second ramp).
  • A 15-year-old male patient volunteered for an 8-week intervention where he performed 30 minutes of treadmill walking, 3 times per week, while wearing a custom-designed knee brace that provided resistance to the thigh muscles of his ACLR leg.
  • A full 8 weeks of FRT that targeted both quadriceps and hamstring muscles lead to improvements in strength and gait, suggesting that FRT may constitute a promising and practical alternative to traditional methods of resistance training.
  • Myocarditis is a known cause of sudden cardiac death in athletes.
  • The currently reported rates of cardiac involvement of COVID-19 makes myocarditis a risk, and physicians who clear athletes for participation in sport as well as sideline personnel should be versed with the diagnosis, management, and clearance of athletes with suspected myocarditis.
  • Given the potentially increased risk of arrhythmias, sideline personnel should practice their emergency action plans and be comfortable using an automated external defibrillator.
