June 2021 Sports Medicine Journal Roundup

This month, we review all of June’s Sports Medicine Journals all in one place here on the sports medicine review.

  • Clinical symptoms in early tendinopathy improved with physical rehabilitation, but this improvement was not augmented with the addition of NSAID treatment.
  • Furthermore, this clinical recovery occurred in the absence of any measurable structural alterations.
  • Finally, clinical improvements after a physical rehabilitation program were greater in patients with very short symptom duration compared with patients who had longer symptom duration.
  • Pertrochanteric calcifications were common radiographic findings in patients with Greater Trochanteric Pain Syndrome and can help guide management in these patients.
  • Proximally and distally directed enthesophytes were strong predictors for the presence of a hip abductor tendon tear, and specifically a full-thickness tear, and increasing size of the findings was associated with more severe tendon injuries.
  • The incidence of Septic Arthritis (SA) after anterior cruciate ligament reconstruction (ACLR) in this nationwide cohort was 1.1%.
  • Male sex, hamstring tendon autografts, and a longer operating time were all independent risk factors for SA.
  • The use of clindamycin as perioperative antibiotic prophylaxis was a risk factor compared with the use of cloxacillin.
  • Some high-volume units had a very low infection rate (0.2%).
  • Patients with severe glenohumeral osteoarthritis who failed previous comprehensive arthroscopic management (CAM) benefited similarly from total shoulder arthroplasty (TSA) compared with patients who opted directly for TSA.
  • At the long-term follow-up of 90 months, ultrasonic percutaneous tenotomy of the brevis and the common extensor tendon, previously shown to enhance recovery of lateral elbow tendinopathy, demonstrated good durability of pain relief and functional recovery that was previously achieved.
  • This was accompanied by sustained sonographic tissue healing with no significant deterioration.
  • Greater exercise volume was associated with lower symptom burden after 1 month of study, and an exercise volume >160 min/wk in the first month of the study was the threshold associated with symptom resolution after the first month of the study.
  • Because our observation on the association between exercise volume and symptom level is a retrospective and secondary outcome, it is possible that participants who were feeling better were more likely to exercise more, rather than the exercise itself driving the reduction in symptom severity.
  • The literature appears to support that blood flow restriction (BFR) can lead to improvements in strength, muscle size, and markers of sports performance in healthy athletes.
  • Combining traditional resistance training with BFR may allow athletes to maximize athletic performance and remain in good health.
  • Additional studies should be conducted to find an optimal occlusive pressure to maximize training improvements.
  • Our results showed that Latarjet had less risk of recurrence and redislocation with longer follow-up time.
  • Both procedures were comparable in terms of Rowe score, the need for revision, and postoperative hematoma formation, whereas Bankart repair was associated with a lower risk of infection.
  • The incidence of acute on-snow severe injury events (SIE) in World Cup alpine ski racing was higher than previously reported.
  • Despite various prevention efforts, the average seasonal incidence of SIE in World and European Cup alpine ski racers has grown from approximately 11 in 1997 to 23 in 2019; thus with roughly one more injured athlete every second season.
  • Low back pain (LBP) in sport is common but estimates vary.
  • Current evidence is insufficient to identify which sports are at highest risk.
  • A previous episode of LBP, high training volume, periods of load increase and years of exposure are common risk factors.
  • Our outcomes highlight the importance of the eye service at the polyclinic as it may represent the only opportunity for many individuals involved with the Olympic and Paralympic Games to receive ocular evaluation.
  • Our description of clinic structure, delivery of service and clinical results will be useful in the organization not only for the Olympic and Paralympic Games Tokyo 2020 but also for any other large sporting events that involves medical attention in a polyclinic format.
  • Injuries incurred while tackling were exclusively the result of suboptimal tackle mechanics.
  • A majority of injuries incurred while being tackled involved a posterior tackle, which often resulted in a posterior collapse of the injured player’s centre of mass over a fixed externally rotated foot.
  • Among patients with knee or hip OA using analgesics, more than half either discontinued analgesic use or shifted to lower risk analgesics following an 8-week structured exercise therapy and patient education program .
  • These data encourage randomized controlled trial evaluation of whether supervised exercise therapy, combined with patient education, can reduce analgesic use, including opioids, among patients with knee and hip OA pain.
  • While several treatments for low back pain (LBP) in athletes improved pain and function, it was unclear what the most effective treatments were, and for whom.
  • Exercise approaches generally reduced pain and improved function in athletes with LBP, but the effect on RTS is unknown.
  • No conclusions regarding the value of manual therapy (massage, spinal manipulation) or biomechanical modifications alone could be drawn because of insufficient evidence.
  • High-quality RCTs are urgently needed to determine the effect of commonly used interventions in treating LBP in athletes.
  • A high-protein (~ 1.6 g kg−1 day−1), exclusively plant-based diet (plant-based whole foods + soy protein isolate supplementation) is not different than a protein-matched mixed diet (mixed whole foods + whey protein supplementation) in supporting muscle strength and mass accrual.
  • This suggests that protein source does not affect resistance training-induced adaptations in untrained young men consuming adequate amounts of protein.
  • This review highlights the effect ACL injury has on lower limb muscle size.
  • Regardless of whether an individual chooses a conservative or surgical approach, the quadriceps of the injured limb appear to have lesser muscle size compared to an uninjured limb.
  • When undertaking reconstructive surgery with a semitendinosus/gracilis tendon graft, the harvested muscle shows lesser muscle size compared to the uninjured limb.
  • This review provides the largest systematic review and meta-analysis of short-sprint performance development methods and the only one to assess football code athletes exclusively.
  • Practitioners can apply combined, secondary and tertiary training methods to improve short-sprint performance within football code athletes.
  • The application of sport only and primary methods does not appear to improve short-sprint performance.
  • Regardless of the population characteristics, short-sprint performance can be enhanced by increasing either or both the magnitude and the orientation of force an athlete can generate in the sprinting action.


  • While the prevalence of high sport specialization was low among Little League baseball players, other behaviors associated with specialization such as year-round play and the receiving of private coaching were more common.
  • Highly specialized Little League players demonstrated worse throwing arm health compared with low-specialization players.
  • For adolescent baseball players, arm care injury prevention programs focusing on important musculoskeletal impairments are effective at reducing injury incidence rates.
  • Multimodal injury prevention programs that improve multiple musculoskeletal impairments are more comprehensive and may result in better injury reduction than programs focusing on a singular impairment.
  • Percutaneous Ultrasonic Tenotomy (PUT) is a minimally invasive treatment technique that can be considered in patients with tendinopathy refractory to conservative treatment measures.
  • Further higher quality studies are necessary to accurately assess the comparative effectiveness of this treatment modality.
  • Interventions focused on addressing a greater degree of plantarflexion range of motion, body mass index, and body mass and their load on the force-absorbing plantar surface structures may be a good starting point in the prevention and treatment of active individuals with Plantar Fasciitis.
