Make It or Break It? Injury Impacts More Than Half of Deselected Athletes Who Dropped Out of the High-Performance Pathway System. A 4-Year Retrospective Cohort Study.

To investigate: (1) the injury epidemiology in an Australian academy; (2) how athletes transition through the high-performance sport (HPS) pathway; and (3) why athletes leave this HPS program. This retrospective cohort study was conducted at an Australian HPS academy over a 4-year period. Medical attention injuries were prospectively recorded. Injury incidence rates (IIR) and burden were calculated per 365 athlete-days, according to sport, sex, and pathway level. Athlete pathway levels were mapped to the Foundations, Talent, Elite, and Mastery (FTEM) framework. Reasons for athletes transitioning out were reported. Four hundred and eighty-one injuries were reported across 124 athletes at an IIR of 2.09 injuries per 365 athlete-days (95% CI = 1.91-2.29). Most athletes (103, 83.1%) were injured at least once over the 4-year period. IIRs increased (IRR = 1.17, 95% CI = 1.06-1.29, p = 0.001) as athletes progressed through the pathway. The most common reason for athlete attrition was deselection due to performance (n = 18), with 55.6% of these athletes sustaining an injury in the season prior to deselection. Injury burden was highest at E2 (119.5 days absence per 365 athlete-days (95% CI = 62.18-229.67)) and lowest at T4 (30.47 days absence per 365 athlete-days (95% CI = 21.98-42.24)). Injury occurrence is common across HPS, with IIRs increasing as athletes progressed to higher talent levels. Deselection due to poor performance was the main attrition factor, with more than half the deselected athletes impacted by injury prior to deselection. This study highlights an increased risk of deselection, following injury, and indicates the need for further development of prevention strategies targeting pathway athletes.

Prospective cohort study identifying risk factors for sports injuries in adolescent athletes: the Healthy Injury-Free Adolescent Athletes (HIFAA) study

A high incidence of injuries has been reported in young athletes. Several factors have been associated with athletes’ sports injuries. However, scientific evidence is lacking, particularly for adolescent athletes. Hence,...

Return to Play at Preinjury Level After Anterior Cruciate Ligament Reconstruction in Divisions II and III National Collegiate Athletic Association Student-Athletes.

The rates of return to play (RTP) after anterior cruciate ligament (ACL) reconstruction among professional and National Collegiate Athletic Association (NCAA) Division I athletes are well described in the orthopaedic literature. Less is known about these rates and risk factors for failure to RTP in Division II and III collegiate athletes. To determine the RTP rate after ACL reconstruction among Division II and III collegiate athletes and to explore the factors associated with RTP. Case series; Level of evidence, 4. Demographic and RTP data were retrospectively reviewed for collegiate athletes who underwent ACL reconstructions across high-risk sports over 6 years (2015/16 to 2021/22 seasons) at 5 northeastern NCAA Division II and III institutions. Clinical data collected included Patient Acceptable Symptom State (PASS) on the Knee injury and Osteoarthritis Outcome Score (KOOS) Sport and Recreation questionnaire, graft type, concomitant reparative surgery, reinjury, need for reoperation, and time to RTP and return to preinjury level. Participants completed the survey using a secure web-based questionnaire sent via email or over the telephone at a minimum 6-month follow-up. Descriptive frequencies were calculated for all documented variables, with chi-square and analysis of variance statistics used to assess for associations and significant differences between variables. A total of 61 eligible student-athletes with primary ACL reconstructions were identified in this study period, and 40 knees were enrolled for analysis with a mean time from surgery to survey completion of 45.0 months. The overall RTP rate was 77.5% (31/40) at a mean of 10.1 months. However, only 50.0% (20/40) returned to their preinjury level of competitive play. There was a graft failure rate of 20% (8/40). Of the 32 athletes who did not reinjure their ACL, 81.25% (26/32) demonstrated a PASS on KOOS Sports and Recreation. Graft rerupture (P < .001) and reoperation (P = .007) had significant effects on rates of RTP. Concomitant procedures (P = .010) influenced return to preinjury level of sports. Injury during the active season versus the off-season significantly influenced KOOS PASS status (P = .038). This study demonstrated that the rate of RTP after ACL reconstruction in this patient population of Division II and III collegiate athletes was 77.5%, with only 50% returning to their preinjury level of competitive play. The graft failure rate in this population was 20%. Surgical factors, such as concomitant surgeries and reinjury of ACL graft, as well as athlete-specific data, such as injury in the off-season, were statistically significant negative influences on patient outcomes. Further research is needed to evaluate other potential factors that may play a role in RTP after ACL reconstruction.

The Use of a Suture Bridge Technique for Arthroscopic Rotator Cuff Repair in Patients Under 40 Years of Age Resulted in Successful Tendon Healing, Pain Relief, Improved Shoulder Function, and High Patient Satisfaction at a Minimum of 5-Year Follow-Up

PurposeThe purpose of this study was to evaluate the long-term clinical and imaging outcomes after arthroscopic repair of rotator cuff tear (RCT) using a suture bridge technique in patients under 40 years of age. MethodA consecutive series of patients who were treated arthroscopically for RCT by a single surgeon between 2016 and 2018 were retrospectively identified. Both full thickness tears and partial tears were included. Arthroscopic cuff repair employed a knotless double-row suture bridge technique, utilizing braided suture tapes. To assess clinical outcomes, we employed the Constant score, the American Shoulder and Elbow Surgeons score (ASES), a strength score, and a visual analog scale (VAS). Tendon healing was evaluated at 12 months using the Sugaya MRI classification. ResultsA total of 63 patients were included in the study. The mean age at the time of the surgery was 33.6 years (range, 21 to 40) and minimum follow up duration was 5 years. Thirty-nine patients reported occasional sports, eight were professional athletes, while sixteen reported no sportive activity prior to first symptoms. Mean follow-up duration was 66.8 months (range, 62.4 to 88.6 months). A significant improvement was observed in both the Constant score and ASES score. The mean Constant score increased significantly from 39.8 (range, 29 to 52) points to 88.9 (range, 34 to 100) points postoperatively (p < 0.001). Similarly, the ASES score improved significantly from 41.8 (range, 30 to 64) to 90.2 (range, 35 to 100, p < 0.001). Anterior flexion mean improved from 86° (range: 60° to 110°) to 137° (range, 90° to 180°, p < 0.001). Pain significantly decreased after the surgery, VAS descending from 6.3 (range, 3 to 10) to 1.3 (range, 0 to 9) postoperatively. The overall rate of return to previous activities in the cohort was 84% at an average of 10.1 months (range, 6 to 12 months) after surgery. Among the included patients, 85% engaging in occasional sports activities and 67% of elite athletes similarly returned to their pre-injury sports levels after 9.8 (range, 6 to 12) months and 10.7 months (range, 6 to 12) respectively. Two patients (3%) experienced cuff re-rupture, and tendon non-healing (Sugaya stage 3 and stage 4) was observed in five (7%) patients. At the final follow-up, 95% of patients were very satisfied or satisfied with their functional results. ConclusionThe use of a suture bridge technique in arthroscopic RCT repair for patients under 40 years of age resulted in excellent long-term outcomes, including successful tendon healing, pain relief, improved shoulder function, and high patient satisfaction.

Isokinetic Strength and Balance Analyses for Predicting Return to Sports After the Latarjet Procedure: A Prospective Cross-sectional Study

Background: Isokinetic torque in shoulder internal rotation (IR) and external rotation (ER) can be considered as potential indicators for dynamic stability of the glenohumeral joint. Purpose: To assess the efficacy of 4-month isokinetic testing in predicting the 6-month return-to-sports (RTS) status after Latarjet surgery, explore its correlations with testing parameters, and identify optimal thresholds to ensure a safe RTS. Study Design: Cohort study; Level of evidence, 2. Methods: The study assessed athletes who underwent the Latarjet stabilization procedure between January 2022 and June 2023. The primary outcome was RTS at 6 months after surgery. The primary examined predictors were isokinetic testing metrics at 4 months postoperatively. Secondary outcomes comprised the modified Closed Kinetic Chain Upper Extremity Stability Test (mCKCUEST) and several patient-reported outcome measures, including the Walch-Duplay score, the Western Ontario Shoulder Instability Index (WOSI), and the Shoulder Instability–Return to Sports after Injury scale. To assess the predictors, patients were divided into those who returned to any level of sports compared with those who did not return to sports. The correlation between isokinetic testing results and other outcome scores was also analyzed. Results: A total of 71 patients (mean age, 27.43 ± 9.09 years) were included in the study. Of these, 23.61% did not return to sports, 38.89% returned at a lower level, and 37.50% returned to the same level. Significant rotational strength disparities were noted. Patients who did not return to sports at 6 months demonstrated inferior strength in concentric ER at 60 deg/s, concentric ER at 240 deg/s, concentric IR at 240 deg/s, and eccentric IR at 30 deg/s (P < .05). Similar trends appeared for all studied patient-reported outcome measures and the mCKCUEST (P < .05). Receiver operating characteristic analysis emphasized the significance of isokinetic testing in concentric ER at 240 deg/s (area under the curve = 0.759; P = .001; cutoff = 0.32 N·m/kg; sensitivity = 100.0%; specificity = 49.1%) and eccentric ER at 30 deg/s (area under the curve = 0.760; P = .001; cutoff = 0.51 N·m/kg; sensitivity = 94.1%; specificity = 49.1%) for RTS prediction. Additionally, ER strength moderately correlated with the Walch-Duplay score across all examined velocities (r = 0.26-0.34; P < .05). The modified WOSI score was weakly linked to ER strength at 240 deg/s and 30 deg/s (r = 0.24-0.25; P < .05) as well as moderately linked to the limb symmetry index in ER at 60 deg/s and 30 deg/s (r = 0.30-0.38; P < .05). Conclusion: Isokinetic testing can act as an independent predictor of successful RTS after Latarjet surgery, with concentric ER at 240 deg/s, concentric IR at 240 deg/s, eccentric ER at 30 deg/s, and eccentric IR at 30 deg/s showing the most accuracy. Strength recovery in ER was associated with better Walch-Duplay and modified WOSI scores.

A meta-analysis of performance advantages on athletes in multiple object tracking tasks

This study compared the multiple object tracking (MOT) performance of athletes vs. non-athletes and expert athletes vs. novice athletes by systematically reviewing and meta-analyzing the literature. A systematic literature search was conducted using five databases for articles published until July 2024. Healthy people were included, specifically classified as athletes and non-athletes, or experts and novices. Potential sources of heterogeneity were selected using a random-effects model. Moderator analyses were also performed. A total of 23 studies were included in this review. Regarding the overall effect, athletes were significantly better at MOT tasks than non-athletes, and experts performed better than novices. Subgroup analyses showed that expert athletes had a significantly larger effect than novices, and that the type of sport significantly moderated the difference in MOT performance between the two groups. Meta-regression revealed that the number of targets and duration of tracking moderated the differences in performance between experts and novices, but did not affect the differences between athletes and non-athletes. This meta-analysis provides evidence of performance advantages for athletes compared with nonathletes, and experts compared with novices in MOT tasks. Moreover, the two effects were moderated by different factors; therefore, future studies should classify participants more specifically according to sports levels.

Relation between Mindfulness and Post-Earthquake Trauma Levels of Students Who Take and Don’t Take Folk Dance Lesson

The aim of this study is to examine the relationship between mindfulness and post-earthquake trauma levels of sports sciences faculty students who take and don’t take folk dance lesson. Mixed models was used both qualitative and quantitative approaches. A total of 94 students, 35 women and 59 men, studying at the faculty of sports sciences, participated in this study. Data were collected using the Mindfulness Scale and the Post-Earthquake Trauma Level Determination Scale. Descriptive statistics, independent samples t-test and Pearson correlation analysis were applied to analyze the data. According to the research results, it was seen that the students were traumatized at a "high" level according to the scores they received from the PETLDS. A significant difference was observed in favor of the students who took folk dance lessons in the affective dimension, one of the sub-dimensions of the post-earthquake trauma scale, in terms of whether the students took folk dance lessons or not and gender variables. It was determined that there was a significant negative relationship between mindfulness scores and post-earthquake trauma scores. Accordingly, it can be said that if university students' mindfulness scores increase, their post-earthquake trauma scores will decrease.

Protracted exercise tolerance post-coronavirus disease 2019 in endurance athletes: A survey.

The global coronavirus disease 2019 (COVID-19) pandemic irrevocably influenced our lives, yet research in a diversity of countries is lacking. Cardiorespiratory fitness may be impaired for up to a year post-COVID-19 infection. Our study aimed to compare acute and exertional symptoms, fatigue, and exercise performance in masters-age endurance athletes according to their return-to-sport status. A cross-sectional survey-based observational study of long-distance runners and cyclists was conducted. Data were stratified into two groups: those who returned to their pre-illness level of sport and those who did not and were compared statistically. A total of 308 survey responses were included in the analysis. The mean age of the athletes was 44.9 + 10.2 years, with 55.2% being male. The group that did not return to their pre-illness level of sport (31.5%) had more post-COVID sequelae, worse illness severity, with a higher frequency of resting and exertional symptoms, notably fatigue and dyspnoea. Decreased exercise capacity was correlated with increased physical fatigue scores. Almost one-third of endurance athletes suffered protracted exercise tolerance post-COVID-19. Long-term symptoms may be more consequential in this athlete population. Symptoms that may indicate cardiopulmonary consequences in recreational athletes should be investigated in order to facilitate return to sport and the important mental and physical benefits thereof. This will augment outcomes after respiratory tract infections and management of return to sport and expectations of endurance athletes.

Outdoor education program reduces anxiety levels in Indonesian sports college students

This study aims to evaluate the impact of the Outdoor Education Program on the anxiety levels of sports students in Indonesia. Using a quantitative approach with an experimental pretest-posttest design, the research included 120 participants, both male and female, aged 18 to 20 years, from sports faculties at the State University of Surabaya, the State University of Yogyakarta, and the Indonesian University of Education. Data collection to assess anxiety levels was conducted through a questionnaire. Validity testing showed all statements were valid, with Pearson Correlation values greater than 0.05, and reliability testing indicated that all items were reliable, with Cronbach's Alpha values exceeding 0.6. Questionnaires were administered via Google Forms before and after the outdoor education program. Data analysis was carried out using SPSS 25. The Wilcoxon test results showed a Sig value greater than 0.05, and the mean posttest score (34.58) was lower than the pretest score (55.66). The study concluded that the Outdoor Education Program significantly reduces anxiety levels in sports students in Indonesia. Further research is recommended to explore the program's effects on students' self-confidence, motivation, responsibility, and discipline.

Returning to pre-injury level of sports before 9 months after medial patellofemoral ligament reconstruction increases the incidence of anterior knee pain in young patients.

This study aimed to identify the risk factors for anterior knee pain (AKP) after medial patellofemoral ligament reconstruction (MPFLR). Patients aged 15-35 years who underwent isolated MPFLR between 2012 and 2022 were included in the study. These patients were divided into two groups (AKP and control group). Patient demographics and preoperativeand postoperative clinical outcomes between the two groups were assessed and compared. Univariate logistic regression analysis was performed to explore the potential risk factors associated with postoperative AKP. Subgroup analysis stratified the results based on the time to return to sports (RTS) (>9 and ≤9 months). Furthermore, Spearman correlation analysis was performed to investigate the association between Kujala score and time to RTS. A total of 206 patients were included (AKP, n = 59; control, n = 147). At the 2-year follow-up, patients with AKP demonstrated a shorter duration in returning to their pre-injury activity level compared to those without AKP (9.0 ± 3.6 vs. 10.3 ± 2.7 months, p < 0.05). RTS earlier than 9 months after MPFLR was the only significant risk factor associated with postoperative AKP (odds ratio, 2.13, 95% confidence interval, 1.03-4.39; p < 0.05). Further subgroup analysis revealed that patientRTS earlier than 9 months exhibited worse patient-reported outcomes in both the total cohort and control group (p < 0.05). Furthermore, among patientRTS within 9 months, a longer recovery duration before RTS strongly correlated with a higher Kujala score (R = 0.670, p < 0.001). Young patients who RTS at their pre-injury levels before 9 months after MPFLR have a higher incidence of postoperative AKP and poorer functional outcomes compared to those who delay their return. Specifically, within the first 9 months after MPFLR, the earlier the RTS, the more severe the AKP symptoms. Careful consideration of the timing for RTS may help reduce the incidence of postoperative AKP. Level III.

Rheological and Biochemical Properties of Blood in Runners: A Preliminary Report

Purpose: Physical activity induces numerous modifications in the morphological, rheological, and biochemical properties of blood. The purpose of this study was to evaluate changes in blood rheological and biochemical indicators among runners. Also, we assessed how the rheological and biochemical properties of blood in people who practised running characterised the range and direction of exercise modifications and allowed for the diagnosis of transient adaptive effects. Methods: This study included 12 athletes who regularly trained in middle- and long-distance running (6–8 times a week) and presented a high sports level (national and international class). The athletes performed a 30 min warm-up consisting of 15 min of jogging and exercises. After a 10 min rest, they completed a 3 km run with submaximal effort. Blood samples were collected at baseline and after the effort. Results: No statistically significant changes were revealed in erythrocyte, leukocyte, platelet, iron, ferritin, transferrin, erythropoietin, or C-reactive protein concentrations in the examined runners. The same applied to the elongation index at a shear stress within the range of 0.30–60.00 Pa, amplitude and total extent of aggregation, aggregation half-life, and aggregation index. A significant increase (within standard limits) was only observed in fibrinogen concentration after running. Conclusions: The lack of post-exercise changes in blood rheological and biochemical indicators in the investigated runners points at an efficient haemorheological system. This, in turn, reflects well-executed training and remarkably well-trained adaptive systems responsible for regeneration.

Factors That Impact Time to Athletic Trainer Evaluation Following Acute Injury Among Secondary School Athletes: A Report from the Athletic Trainin Practice-Based Research Network.

Immediate athletic trainer (AT) availability for acute injuries is essential as worse long-term outcomes are associated with delays in receiving medical care. Several factors have been found to influence AT availability between secondary schools, but few studies have evaluated how medical coverage varies between athlete groups. The purpose of this project was to identify factors that impact the time to AT evaluation following acute sport-related injury in secondary school setting. Cross-Sectional Study. Retrospective analysis of de-identified patient records via the Athletic Training Practice-Based Research Network. High school athletes diagnosed with an acute sport related injury during in-season play from 2010-2023. Time to AT evaluation was measured as the number of days between injury onset, reported by the patient, to AT evaluation. This report consists of 17,354 patient cases representing 20 different sports. Overall, 46.9% (n=8,138) of patients who sustained an injury during in-season play were evaluated by an AT the same day (range=0-14days). Significant group differences were reported for sex (p <. 001), setting (p <. 001), and sport level (p < .01), with females and in-game injuries associated with longer times to AT evaluation. Freshmen were evaluated sooner than JV (p < .01) and varsity (p < .001) athletes. No difference was observed between JV and varsity athletes (p=0.34). Almost half of patients received medical care within 24 hours following an acute injury during in-season play, highlighting how qualified health care is accessible for many student athletes through ATs in the secondary school setting. Differences in time to AT evaluation may be attributable to sex discrepancies in immediate medical coverage between sports and injury reporting patterns among athletes.

The Impact of Spine Injuries on Amateur Athletes: An Exploratory Analysis of Sport-Related Patient-Reported Outcomes.

There is a lack of information on return to sport and patient-reported outcome measures (PROMs) in amateur athletes after isolated spine injuries. A single-center cohort study in amateur athletes aged 18 to 60 with isolated spine injuries; clinical data collection and follow-up via telephone interview and standardized PROMs (Short-Form 36, Oswestry and Neck Disability Index, Tampa Scale of Kinesiophobia, Hospital Anxiety and Depression Scale, Pain Visual Analog Scale). Bivariate analyses of potential influencing factors on PROMs were conducted using the Wilcoxon Signed-Rank Test. p-values < 0.05 were considered statistically significant. Out of the 80 included participants, 78% (n = 62) were active in sport at follow-up. PROMs were slightly worse than those described for the age-adjusted general population. There were consistent associations of better PROMs with having reached the subjective preinjury level of performance in sport, while injury severity and surgical or conservative therapy did not show consistent associations with PROMs. Most amateur athletes resume their sports activity after a spine injury. Better outcomes are associated with individuals' resumption of sport and subjective level of performance, while injury severity and surgical or conservative therapy do not show consistent associations with PROMs, highlighting the importance of patient education, rehabilitation, and encouragement.

Evaluating Return to Sports After Surgical Treatment of Unstable Osteochondritis Dissecans of the Knee: A Systematic Review.

Although the incidence of osteochondritis dissecans (OCD) of the knee may be low, an overview and comparison of sports-related outcomes with current surgical management techniques are needed. To summarize the available evidence regarding outcomes for different surgical treatment options for unstable OCD of the knee in both skeletally mature and immature patients by calculating the return to sports (RTS) rate, the mean RTS time, and other sports-related postoperative outcome measures. Systematic review; Level of evidence, 4. A systematic review of studies on RTS after surgical correction of unstable OCD within the knee was conducted utilizing PubMed, Embase, and the Cochrane databases. Included were studies discussing the treatment of unstable OCD with minimum 1-year follow-up outcomes. Multivariate analysis was used to compare studies grouped together based on RTS and skeletal maturity. Of 2229 articles, 6 studies (197 patients; 198 knees) met the inclusion criteria and were included in our analysis. The percentage of patients who returned to the previous level of sport ranged from 52% to 100%; those returning to any level of sport ranged from 87% to 100%. Clinical outcomes did not differ between patients with open versus closed physes. Osteochondral Autograft Transfer System (OATS) procedures had a 100% RTS rate across several studies with skeletally mature and mixed cohorts, and microfracture had the lowest overall RTS rate (52%). For skeletally immature patients, all examined studies that utilized either open or arthroscopic reduction and internal fixation, 77% and 78%, respectively, had acceptable RTS rates. Arthroscopic fixation had a higher rate of revision surgery in both skeletally mature and immature patients. Our analysis indicated that the treatment of unstable OCD lesions using the OATS technique demonstrated high RTS rates across several studies, while microfracture alone exhibited the lowest RTS rate. Both arthroscopic and open internal fixation utilizing bioabsorbable screws yielded satisfactory RTS rates for juvenile patients with OCD.

Effect of Different Screw Materials on ACL Reconstruction With the Tape Locking Screw Technique: A Retrospective Study From the FAST Cohort.

Screws for graft fixation are available in 3 different materials for anterior cruciate ligament reconstruction (ACLR) with the Tape Locking Screw (TLS) technique: titanium, poly-l-lactic acid bioabsorbable, and polyetheretherketone (PEEK). To compare the effect of the 3 different fixation materials on graft and implant survival after ACLR with the TLS technique. Cohort study; Level of evidence, 3. Included were 521 patients from the French Prospective ACL Study (FAST) cohort who underwent primary surgical ACLR with the TLS technique. Patients were divided into 3 groups depending on the type of screw material used: titanium (TLS-T group), poly-l-lactic acid bioabsorbable (TLS-B group), or PEEK (TLS-P group). The primary endpoint was a retear within 2 years after ACLR. The secondary endpoints were complication rate, return to sports rate, and functional scores. Objective and subjective functional scores-including the International Knee Documentation Committee, the Knee injury and Osteoarthritis Outcome Score (KOOS), and the Lysholm score-were evaluated preoperatively and at the 2-year follow-up. Pain was assessed with the KOOS-Pain subscore recorded pre- and postoperatively every 6 months up to 2 years. Patient satisfaction was recorded at the 2-year follow-up. No significant differences between the study groups were found in retear rates (4.4%, 4.5%, and 4.3% in the TLS-T, TLS-P, and TLS-B groups 2 years after surgery) or subjective and objective outcomes. The TLS-T group had the lowest rate of intraoperative implant-related complications (0.9%) compared with the TLS-P (4.3%) and TLS-B (7.7%) groups. Young age was a significant risk factor for retear in the TLS-T (P = .03) and TLS-B (P = .0001) groups, while a high level of sports was found to be a significant risk factor in the TLS-P (P = .04) group. All functional scores improved significantly at the 2-year follow-up (P < .0001), with no significant group difference. The KOOS-Pain subscore improved continuously with no significant group difference. The rate of return to preinjury sports was between 43.4% and 58.6%. The rate of highly satisfied patients at the final follow-up was between 86.2% and 91.8%. There was no difference in retear rate or objective and subjective functional scores between implant materials for TLS ACLR in this study.

Safety and Early Return to Sports for Early ACL Reconstruction in Young Athletes: A Retrospective Study.

Background and Objectives: Although previous reports have shown that early anterior cruciate ligament (ACL) reconstruction is associated with an increased risk of stiffness, recommendations for delayed surgery are based on outdated literature. The advent of arthroscopic surgery and accelerated rehabilitation protocols warrants a reexamination of the optimal surgical timing. The purpose of this study was to investigate complications during early ACL reconstruction after injury in young athletes. Materials and Methods: A total of 87 patients (27 males and 60 females) were included in this study. Patients who underwent anatomic ACL reconstruction using hamstring autografts were evaluated. Patients under 25 years of age with a Tegner activity score greater than 6 were included and classified into three groups according to the time from injury to surgical treatment: one week from injury to surgery (early group), three to six weeks from injury to surgery (normal group), and three to six months from injury to surgery (delayed group). We evaluated the rates of various complications such as graft rupture, contralateral injury, the need for manipulation for loss of ROM, infection, and fracture around the knee up to 2 years postoperatively. In addition, we investigated postoperative muscle strength, Lysholm score, Tegner activity score, and period of the return to sport from injury. Results: Patients in the delayed group were younger than those in the other groups (p = 0.009). Patients in the early group had a lower range of motion than those in the other groups preoperationly. However, the 1-month postoperative range of motion was comparable between groups. Patients in the early group had greater postoperative Tegner activity scores than those in the other groups. The period of return to sport from injury in the delayed group was longer than in the other groups. There were no statistically significant differences in the postoperative complication rate, muscle strength, or Lysholm score. Conclusions: ACL reconstruction performed 1 week from injury to surgery in young athletic patients indicated the rate of complications were not significantly different among the groups. Early ACL reconstruction with no postoperative complications may be related to early return to sports and a high level of sports.

Association of combined low physical activity and low dietary diversity with mild cognitive impairment among community-dwelling Japanese older adults.

This study aimed to investigate the potential association between the combination of low physical activity and low dietary diversity with mild cognitive impairment (MCI) in older Japanese adults. Data from 600 older adults (mean age 74.1 ± 6.4 years; 62.0% women) were analyzed. We evaluated dietary variety based on the Food Frequency Score (FFS) (maximum 30 points) by assessing the one-week consumption frequencies of ten foods. An FFS of ≤ 16 indicated low dietary diversity. We assessed MCI using the National Center for Geriatrics and Gerontology (NCGG) Functional Assessment Tool. Physical activity levels was determined based on participant responses to two questions: "Do you engage in moderate levels of physical exercise or sports aimed at health?" and "Do you engage in low levels of physical exercise aimed at health?". Participants who responded "No" to both questions were classified as having low physical activity levels. We classified the participants into robust, low-dietary diversity, low-physical activity, and coexistence groups. The overall prevalence of MCI was 20.7%, with rates in the robust, low dietary diversity, low physical activity, and coexistence groups of 17.7%, 24.7%, 25.0%, and 41.9%, respectively. Multiple logistic regression analysis revealed that low dietary diversity and physical activity were associated with MCI in older adults (odds ratio [OR] 2.80, 95% confidence interval [CI] 1.22-6.28). The results of the present study demonstrated the association of the co-occurrence of low dietary diversity and low physical activity with MCI. Older adults with both risk factors may require early detection, as well as physical activity and dietary interventions.

Ligament augmentation and reconstruction system (LARS) synthetic grafts are safe and effective for medial collateral ligament and posterolateral corner reconstructions in elite athletes.

This study documents the efficacy and safety of using a Ligament Augmentation and Reconstruction System (LARS) ligament graft to augment extra-articular knee ligament reconstructions in elite athletes by reporting return-to-play(RTP) rates and levels, career longevityand complications. A consecutive series of all extra-articular knee ligament reconstructions augmented by LARS ligaments in elite athletes undertaken by three specialist sports knee surgeons between 2013 and 2020 were reviewed. Seventy-six elite athletes, aged over 16 years old, and more than 2 years postsurgery were included. RTPwas defined as competing at professional levelor national/international level in amateur sport. There were 64 medial collateral ligament (MCL) and 12 posterolateral corner (PLC) reconstructions. Fifty-two (68.4%) underwent concomitant autograft cruciate ligament(s) reconstruction. The mean age was 25.1 years (SD ± 4.5). Most were football (35, 46.1%) or rugby players (35, 46.1%). Sixty-seven athletes (88.2%) RTP with 65 (97.0%) of these playing at the same or higher Tegner level. Fifty-six (83.6%) of the athletes that RTP were still playing at 2 years postsurgery. Twenty (57.1%) of those who had RTP and were more than 5 years postsurgery were still playing at 5 years. Six (7.9%) players required further surgery relating to the LARS/metalwork. One case had soft tissue inflammation adjacent to the proximal end of the synthetic graft, but it is unknown if this was mechanical irritation or a biological reaction. One MCL reruptured 4 years after RTP. Utilising LARS to augment extra-articular knee ligament reconstructions allows 88.2% of athletes with a variety of knee ligament injuries to return to elite sport. The low morbidity rates coupled with 57% of athletes still playing 5 years postsurgery demonstrates that the LARS is safe and effective in these cases. Although there are reports of LARS ligaments being used in MCL and PLC reconstructions, there is very little evidence investigating if they are safe and effective. This study demonstrates that LARS synthetic grafts can be safely used for MCL and PLC reconstructions in elite athletes and they permit a high RTP with a low risk of complications. Level IV.

Operative management of chronic isolated rectus femoris rupture with semitendinosus graft and biofiber: A case report

Rectus femoris tear is rare and often overlooked in emergencies. The majority of quadriceps muscle belly injuries can be successfully treated conservatively and for less active, older populations Non-operative management is reasonable. A case report of a 19-year-old male Kabbaddi player who sustained an injury to his rectus femoris muscle belly while playing 5 months back. This young patient did not recover the functional outcome required to get back to running and participating in kabaddi despite 5 months of physiotherapy and non-operative management and had complaints of Pain over midthigh and weakness in quadriceps during hip flexion and knee extension. This leads to Hindrances in Jumping, running, and kicking movements. Tenderness over the midthigh and palpable defect with Pain upon resisted hip flexion or extension was seen.3/5 quadriceps power was noted. Ultrasound and MRI were done to confirm the clinical diagnosis. Operative treatment using the semitendinosus allograft with bio fiber reconstruction system to augment rectus femoris repair allowed immediate full passive flexion of the knee and an early graduated physiotherapy program leading to a return to running and his previous level of sport without any restrictions. Surgical treatment of rectus femoris tear seems to be a good option for Chronic tears.
