In the present study, we sought to determine if a comprehensive school physical activity program (CSPAP) delivered using the Be a Champion! (BAC) framework was effective in increasing moderate-to-vigorous physical activity (MVPA) and decreasing sedentary time in elementary school youth.
We implemented a CSPAP in 3 elementary schools to determine its effectiveness to youth behaviors compared to 2 control schools. Youth physical activity was assessed via accelerometry in spring 2015 and spring 2016 during school hours on school days. Implementation of the BAC components and youth behavior was assessed through direct observation from fall 2015 through winter 2016.
In a multilevel, mixed model examining the effects of intervention, we found no statistically significant effect of the intervention on overall MVPA. However, a significant increase in MVPA was observed among girls (but not boys) in the intervention schools relative to controls. No differences in sedentary behaviors were observed by group.
CSPAP implementation may be effective in reducing sedentary time and increasing MVPA in girls, but not boys. Research is necessary to increase implementation dose and fidelity to best practices in physical activity promotion.

Selective androgen receptor modulators (SARMs) have been developed to enhance muscle bulk without the side effects associated with exogenous androgen steroids. We report a case of significant cholestatic liver injury associated with a SARM, ostarine (enobosarm), similar to that associated with anabolic steroids. Liver injury from SARMs has not been reported frequently, and we speculate that this may be seen more often as the consumption of SARMs increases in the athletic market.
Femoral nerve block (FNB) and adductor canal block (ACB) have been used increasingly for pain control during anterior cruciate ligament (ACL) reconstruction in adolescent patients. However, recent evidence suggests that the use of FNB may affect quadriceps strength recovery 6 months after surgery.
To compare postoperative isokinetic strength in adolescents who received FNB, ACB, or no block for perioperative analgesia during ACL reconstruction. We anticipated lower postoperative quadriceps and hamstring isokinetic deficits in adolescents who received FNB as compared with ACB.
Cohort study; Level of evidence, 3.
Patients were included in the study if they had undergone hamstring tendon autograft ACL reconstruction by a single surgeon from July 2008 to January 2018 and if they underwent isokinetic muscle testing at 4 to 8 months postoperatively. The participants were divided into 3 groups (no block, FNB, and ACB), and we compared the deficit in percentages between the affected and unaffected limbs as caroximately 6 months after ACL reconstruction. The only significant strength deficit was seen in the hamstrings of patients receiving ACB at peak flexion as compared with those receiving FNB.
Contrary to previous research, our findings indicate only minimal difference in quadriceps strength among the 3 types of perioperative analgesia in adolescents approximately 6 months after ACL reconstruction. The only significant strength deficit was seen in the hamstrings of patients receiving ACB at peak flexion as compared with those receiving FNB.
Excessively high joint loading during dynamic movements may negatively influence articular cartilage health and contribute to the development of posttraumatic osteoarthritis after anterior cruciate ligament reconstruction (ACLR). Little is known regarding the link between aberrant jump-landing biomechanics and articular cartilage health after ACLR.
The purpose of this study was to determine the associations between jump-landing biomechanics and tibiofemoral articular cartilage composition measured using T1ρ magnetic resonance imaging (MRI) relaxation times 12 months postoperatively. We hypothesized that individuals who demonstrate alterations in jump-landing biomechanics, commonly observed after ACLR, would have longer T1ρ MRI relaxation times (longer T1ρ relaxation times associated with less proteoglycan density).
Cross-sectional study; Level of evidence, 3.
A total of 27 individuals with unilateral ACLR participated in this cross-sectional study. Jump-landing biomechanics (peak vertical ground-react = 0.20;
= .02) and central LFC (Δ
= 0.15;
= .05). Peak KAM was not associated with T1ρ outcomes.
At 12 months postoperatively, lower peak KEM and greater peak vGRF during jump landing were related to longer T1ρ relaxation times, suggesting worse articular cartilage composition.

Nearly 20% of acute ankle sprains progress to chronic lateral ankle instability that requires surgical intervention. Veliparib in vivo In recent years, there has been a growing interest in arthroscopic Broström techniques as an alternative to open surgery.
To review the most up-to-date evidence comparing the outcomes of open and arthroscopic Broström procedures for chronic lateral ankle instability.
Systematic review; Level of evidence, 3.
This review was performed following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Relevant comparative studies in English up to May 2020 were identified. The primary outcomes were (1) functional scores (Karlsson Ankle Function Score and American Orthopaedic Foot & Ankle Society [AOFAS] score) and (2) the 10-point visual analog scale (VAS) score for pain. The secondary outcomes were differences in (1) postoperative anterior drawer and talar tilt, (2) surgical time and complication rate, and (3) time to return to sports and weightbearinGould surgery in postoperative AOFAS scores, VAS pain scores, and time to return to weightbearing. The operative time, complication rate, talar tilt, and anterior drawer tests were excellent and statistically comparable. Long-term clinical trials are required before recommending arthroscopic Broström as the new gold standard.
While technically more demanding, arthroscopic Broström was superior to open Broström-Gould surgery in postoperative AOFAS scores, VAS pain scores, and time to return to weightbearing. The operative time, complication rate, talar tilt, and anterior drawer tests were excellent and statistically comparable. Long-term clinical trials are required before recommending arthroscopic Broström as the new gold standard.
The choice of graft in anterior cruciate ligament (ACL) reconstruction is still under discussion. The hamstrings are currently the most used grafts for primary ACL reconstruction in Europe. However, increased interest has arisen in the quadriceps tendon (QT) as an alternative autologous graft option for primary ACL reconstruction.
To evaluate knee stability and the subjective outcome after ACL reconstruction using either autologous QT graft in implant-free femoral press-fit fixation technique or semitendinosus tendon (ST) graft.
Cohort study; Level of evidence, 2.
We evaluated 50 patients who underwent ACL reconstruction, including 25 patients who received autologous ipsilateral QT graft (QT group) and 25 patients who received the ipsilateral ST graft (ST group). The follow-up for this prospective comparative study was at least 2 years after surgery, comprising KT-1000 arthrometer testing, pivot-shift test, Knee injury and Osteoarthritis Outcome Score (KOOS), Lysholm score, and rerupture rate.
The mean patient age was 31.72 years (9 women, 16 men) in the QT group and 32.08 years (13 women, 12 men) in the ST group. The mean ± standard deviation postoperative side-to-side difference assessed using KT-1000 arthrometer was 1.56 ± 1.56 mm for the QT group and 1.64 ± 1.41 mm for the ST group, with no significant difference. No significant difference was found on any of the KOOS subscale scores (
= .694) or the Lysholm score (
= .682). No rerupture or positive pivot-shift test occurred during follow-up. No difference was found in donor-site morbidity between the study groups.
Clinical outcomes were not significantly different between QT and ST grafts in the current study. Thus, the QT may serve as a good alternative graft for primary ACL reconstruction.

Simulation provides low-risk opportunities for surgical trainees to learn and practice fundamental skills. One simulation tool for orthopaedics is the Arthroscopic Knot (ArK) Trainer, which has been validated as an effective simulation tool across multiple methodologies. Previous studies have investigated the ArK Trainer in its basic form using clear plexiglass, which allows direct visualization of tissue anchors.
Using a mixed-methods approach, we assessed and compared junior and senior trainees' Seoul Medical Center (SMC) knot-tying performance under direct and indirect visualization.
Cross-sectional study.
Fourteen orthopaedic surgery postgraduate trainees at a single medical school were recruited to participate. Trainees tied SMC knots using the Ark Trainer under direct and indirect visualization. A mixed-methods approach was used to evaluate knot-tying proficiency and characterize participants' approach to knot-tying. Knot-tying proficiency was evaluated using validated tools a task-specific checiciency. Trainees recommended progression from direct to indirect visualization configurations for inexperienced learners.
There is a lack of information regarding the reasons why patients do not return to sports after an arthroscopic Bankart repair and whether there is a relationship between return to sports and functional outcomes.
To evaluate the reasons why competitive athletes who underwent arthroscopic Bankart repair did not return to sports and whether there was a relationship between returning to sports and postoperative outcome scores and complications.
Cohort study; Level of evidence, 3.
Of 217 competitive athletes who underwent arthroscopic Bankart repair for isolated anterior glenohumeral instability between June 2014 and December 2017, a total of 208 athletes (96%) were evaluated at minimum 2-year follow-up. Return to sports, the level of sports achieved, and the time between surgery and return to competition were assessed, and patients who did not return to sports were asked to provide the reasons for cessation. The Rowe score and the Athletic Shoulder Outcome Scoring System (ASOSS) were used to assess functses being fear of reinjury and a concern about new rehabilitation process. Neither outcome scores nor complications varied significantly between patients who returned and those who did not return to sports.
Of patients who did not return to sports, 74% left for a reason independent of shoulder function, with the most frequent causes being fear of reinjury and a concern about new rehabilitation process. Neither outcome scores nor complications varied significantly between patients who returned and those who did not return to sports.
