Preoperative Predictors

In this study, we performed a retrospective and prospective study of preoperative predictors of the length of stay (LOS) in three groups of surgical patients and conducted a clinical retrospective study of the current research status of preoperative predictors of LOS prolongation in three groups of patients under ERAS (enhanced recovery after surgery) mode, such as patient characteristics and comorbidities. Information such as patients’ exercise preferences, exercise time, frequency and duration, footwear, location of knee osteoarthritis, whether there is a past history of knee injury, and smoking and drinking history was collected, and the research data of 312 patients undergoing the three operations were analyzed by SPSS. Meniscal injury-knee arthroscopy sample included a total of 104 people. Surgical sample for anterior cruciate ligament reconstruction included a total of 100 subjects. Knee osteoarthritis-knee replacement surgery sample included 148 people who were divided into two groups in a ratio of 1 : 1: one group used Mailuo Shutong pills during hospitalization (intervention group) and the other group did not (control group). The research conclusions are as follows. Meniscal Knee Arthroscopy. (1) Samples from different causes of injury showed significant differences for all injured sites. (2) Samples with different smoking and drinking histories all showed significant differences for the causes of injury. (3) Exercise hobby, exercise frequency, duration of each exercise and duration of exercise, and warm-up time before exercise all showed positive correlation. Anterior Cruciate Ligament Reconstruction Surgery. (4) Samples from different causes of injury showed significant differences for all the injured sites. (5) Age has a significant negative influence on the wearing of shoes at ordinary times. (6) Exercise hobby: the warm-up time before exercise had a significant negative influence on the injured area. (7) Two groups of analysis items of exercise frequency, exercise duration and exercise duration, preexercise warm-up time, and exercise hobby were typically positively correlated. Total Knee Arthroplasty. (8) There was a significant difference of 0.01 between the hospitalization days of the intervention group and the control group ( p < 0.01 ), and the hospitalization days of the intervention group were significantly lower than those of the control group. These results indicated that Mailuo Shutong pills were of great significance for the treatment of orthopedic patients during the operation period in that it could effectively shorten the hospital stay of all orthopedic patients and strengthen the accelerated rehabilitation. (9) There was a significant positive correlation between the history of knee joint surgery and the use time of Mailuo Shutong pills. (10) There was a markable positive correlation between occupation and sports hobbies, sports time, frequency and duration, and footwear. There was a significant negative correlation between occupation and preexercise warm-up. (11) Exercise time, frequency, and duration have significant positive influence on BMI.

Context: There is no evidence regarding the effect of the FIFA 11+ on landing kinematics in male soccer players, and few studies exist regarding the evaluating progress of interventions based on the initial biomechanical profile. Objective: To investigate the effect of the FIFA 11+ program on landing patterns in soccer players classified as at low or high risk for noncontact anterior cruciate ligament injuries. Design: Randomized controlled trial. Setting: Field-based functional movement screening performed at the soccer field. Participants: A total of 24 elite male youth soccer players participated in this study. Intervention: The intervention group performed the FIFA 11+ program 3 times per week for 8 weeks, whereas the control group performed their regular warm-up program. Main Outcome Measures: Before and after the intervention, all participants were assessed for landing mechanics using the Landing Error Scoring System. Pretraining Landing Error Scoring System scores were used to determine risk groups. Results: The FIFA 11+ group had greater improvement than the control group in terms of improving the landing pattern; there was a significant intergroup difference (F1,20 = 28.86, P < .001, ). Soccer players categorized as being at high risk displayed greater improvement from the FIFA 11+ program than those at low risk (P = .03). However, there was no significant difference in the proportion of risk category following the routine warm-up program (P = 1.000). Conclusions: The present study provides evidence of the usefulness of the FIFA 11+ program for reducing risk factors associated with noncontact anterior cruciate ligament injuries. The authors’ results also suggest that soccer players with the higher risk profile would benefit more than those with lower risk profiles and that targeting them may improve the efficacy of the FIFA 11+ program.

Background: Anterior cruciate ligament (ACL) injuries are among the most common and devastating sports-related knee injuries. Neuromuscular training (NMT) has demonstrated efficacy as a preventive intervention for ACL injury and has been associated with improvements in measures of sports performance, but the specific physiologic mechanisms that serve as protective factors and contribute to improved performance haven not been well-defined. Hypothesis/Purpose: The purpose of this study is to investigate the association between NMT and biomechanical efficiency among high school athletes. We hypothesized that the performance of NMT is associated with improved biomechanical efficiency during the performance of fundamental movements and agility tests when compared to a group of untrained control subjects. Methods: Eight high school soccer and basketball teams (111 athletes, 53.1% male, mean age 15.6 years) were recruited and assigned to either an intervention or control group. The intervention group performed NMT as part of their warm-up prior to each practice and competition for 12 weeks. NMT was administered by experienced sports medicine clinicians who provided exercise instruction, technique cues, and performance feedback throughout each training session. The control group performed their customary warm-up under the direction of the team’s coaches. Biomechanical efficiency was assessed through performance of static and dynamic tests using an FDA-approved wireless sensor system. Agility was assessed using a timed three-cone agility test. All tests were administered immediately prior to and following each competitive sports season. Results: Matched pre-/post-season data was collected from 74 athletes (67%). Significant improvements [point estimate (95% CI) p-value] were observed in the intervention group for left lower extremity [0.25 (0.06,0.45) p = 0.01] and right lower extremity [0.21 (0.05,0.37) p = 0.01] loading/landing speed ratios during a single leg hop test, left lower extremity [-136.34 (-225.74,-46.95) p = 0.003] and right lower extremity [-110 (-211.36,-8.64) p = 0.03] ground reaction force, left lower extremity [-1.03, (-.189,-0.18) p = 0.02] and right lower extremity [-0.94 (-1.73,-0.14) p = 0.02] initial peak acceleration, and cadence [-12.12 (-21.60,-2.65) p = 0.01] during a straight-line running acceleration/deceleration test, and time [0.51 (0.24,0.78) p = 0.0003] during a three-cone agility test. Conclusion: Results demonstrate that season-long, sport-specific, age-appropriate NMT administered by sports medicine clinicians can significantly improve biomechanical efficiency during the performance of fundamental movements and agility tests by high school athletes. To achieve similar results, sports coaches should be trained to provide exercise instruction, technique cues, and performance feedback when administering NMT in real-world settings.

Background: The online intervention Runfitcheck was developed to stimulate injury-preventive behaviour among adult novice runners. Objective: The objective of this study was to evaluate the effectiveness of Runfitcheck on injury-preventive behaviour among adult novice runners. Material and methods: A randomised controlled trial was conducted among adult novice runners. The intervention group had access to the Runfitcheck intervention, the control group performed their running activities as usual. One, three, and five months after enrolment, participants reported retrospectively what they had done regarding injury-preventive behaviour (operationalised as (i) using a (personalised) training schedule; (ii) performing strength and technique exercises; and (iii) performing a warm-up routine prior to running). Relative Risks (RR) and 95% Confidence Interval (95%CI) were used to analyse behavioural change. Results: The intervention group (n=715) searched more often for information about a warm-up routine (RR 1.211; 95%CI 1.080-1.357), added more often strength exercises to their warm-up routine ( RR 1.228; 95%CI 1.092-1.380). The intervention group performed more often running technique exercises compared to the control group (n=696) (RR 1.134; 95%CI 1.015-1.267), but less often strength exercises (RR 0.865 (95%CI 0.752-0.995). Within the group of runners that did not perform any warm-up routine at enrolment (n=272), the intervention group performed a regular warm-up routine more often than the control group (RR 1.461; 95%CI 1.084-1.968) No significant results were found for using a training schedule. Discussion and conclusion: The online intervention Runfitcheck was effective in stimulating aspects of injury-preventive behaviour in adult novice runners, mostly related to a warm-up routine.

ObjectiveTo study whether an injury prevention exercise programme would reduce the number of injuries in youth floorball players.Methods 81 youth community level floorball teams (48 clusters=clubs) with female and male players (12–17 years) were cluster-randomised into an intervention or control group. Intervention group coaches were instructed to use the Swedish Knee Control programme and a standard running warm-up before every training session, and the running warm-up before every match, during the season. Control teams continued usual training. Teams were followed during the 2017/2018 competitive season (26 weeks). Player exposure to floorball and occurrence of acute and overuse injuries were reported weekly via a web-based player survey using the Oslo Sports Trauma Research Centre Questionnaire.Results 17 clusters (301 players) in the intervention group and 12 clusters (170 players) in the control group were included for analyses. There were 349 unique injuries in 222 players. The intervention group had a 35% lower incidence of injuries overall than the control group (adjusted incidence rate ratio (IRR) 0.65, 95% CI 0.52 to 0.81). The absolute risk reduction was 6.6% (95% CI 3.2 to 10.0), and the number needed to treat was 152 hours of floorball exposure (95% CI 100 to 316). Intervention group teams had a 45% lower incidence of acute injuries (adjusted IRR 0.55, 95% CI 0.37 to 0.83). There was no difference in the prevalence of overuse injuries (adjusted prevalence rate ratio 0.96, 95% CI 0.73 to 1.26).Conclusion The Knee Control injury prevention programme reduced acute injuries in youth floorball players; there was no effect on overuse injuries.Trial registration numberClinical Trials NCT03309904.

Abstract Background In addition to the beneficial health effects of being active, running is also associated with a risk of sustaining injuries. The online intervention Runfitcheck was developed to stimulate injury-preventive behaviour among adult novice runners. The objective of this study was to evaluate the effectiveness of Runfitcheck on injury-preventive behaviour among adult novice runners. Design Randomised controlled trial Methods A randomised controlled trial with a follow-up period of five months was conducted among adult novice runners. The intervention group had access to the Runfitcheck intervention, while the control group performed their running activities as usual. One, three, and five months after enrolment, participants reported retrospectively what they had done regarding injury-preventive behaviour (operationalised as (i) using a (personalised) training schedule; (ii) performing strength and technique exercises; and (iii) performing a warm-up routine prior to running). Relative Risks ((RR) and 95% Confidence Interval (95%CI)) were used to analyse behavioural change among runners who were not performing the favourable behaviour at enrolment. Results A total of 1,411 novice runners (72.6% female, mean age 38.1 years) were included in this study and assigned to the intervention group (n=715) or control group (n=696). Runners in the intervention group searched more often for information about a warm-up routine (55.6% versus 44.9%; RR 1.211 (95%CI 1.080-1.357); Table 2), and added more often strength exercises to their warm-up routine (49.3% versus 38.2%; RR 1.228 (95%CI 1.092-1.380)). Runners in the intervention group performed more often running technique exercises compared to runners in the control group (58.6% versus 51.5%; RR 1.134 (95%CI 1.015-1.267)), but less often strength exercises (71.9% versus 77.9%; RR 0.865 (95%CI 0.752-0.995)). Within the group of runners that did not perform any warm-up routine at enrolment (n=272; 69.5% female, mean age 35.8 years (SD 9.3), runners in the intervention group performed a regular warm-up routine more often than runners in the control group (47.1% versus 28.4%; n=196; RR 1.461 (95%CI 1.084-1.968)) No significant results were found for using a training schedule. Conclusions The online intervention Runfitcheck was effective in stimulating aspects of injury-preventive behaviour in adult novice runners, mostly related to a warm-up routine.

Background: Prevention of sports injuries is essential in youth, as injuries are associated with less future physical activity and thus greater all-cause morbidity. Purpose: To investigate whether a neuromuscular training warm-up operated by team coaches is effective in preventing acute lower extremity (LE) injuries in competitive U11-U14 soccer players. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Twenty top-level U11 to U14 soccer clubs in Finland were randomized into intervention and control groups and assessed for 20 weeks. Participants included 1403 players (280 female, 1123 male; age range, 9-14 years): 673 players (44 teams) in the intervention group and 730 players (48 teams) in the control group. The intervention group team coaches were introduced to a neuromuscular training warm-up to replace the standard warm-up 2 to 3 times per week. The control teams were asked to perform their standard warm-up. Injury data collection was done via weekly text messages. The primary outcome measure was a soccer-related acute LE injury, and the secondary outcome measure was an acute noncontact LE injury. Results: A total of 656 acute LE injuries occurred: 310 in the intervention group and 346 in the control group. The overall acute LE injury incidence was 4.4 per 1000 hours of exposure in the intervention group and 5.5 per 1000 hours of exposure in the control group, with no significant difference between groups (incidence rate ratio [IRR], 0.82 [95% CI, 0.64-1.04]). There were 302 acute noncontact LE injuries: 129 in the intervention group (incidence, 1.8 per 1000 hours) and 173 in the control group (2.7 per 1000 hours). A significant reduction in acute noncontact LE injuries of 32% (IRR, 0.68 [95% CI, 0.51-0.93]) was observed in the intervention group compared with the control group. Furthermore, significant reductions in injury incidence in favor of the intervention group were seen in the subanalyses of acute noncontact LE injuries, leading to ≤7 days of time loss and fewer ankle and joint/ligament injuries. Conclusion: A neuromuscular training warm-up operated by team coaches was found to be effective in preventing acute noncontact LE injuries in children’s soccer, but this was not seen in all acute LE injuries. Clinical Relevance: We encourage children’s soccer coaches and health care professionals to implement neuromuscular training warm-up in youth sports. Registration: ISRCTN14046021 (ISRCTN registry).

ObjectivesThe psychological and physical recovery after anterior cruciate ligament (ACL) reconstruction (ACLR) may or may not occur in parallel. A common scenario is the uninformed athlete who lacks awareness of physical deficiencies and returns to sport prematurely. There is increasing evidence that most patients do not meet return to play criteria at 6 months and physical deficits may still persist 1 year after surgery. We hypothesise that a Quality of Movement Assessment for Return to Sport (QMA-RTS) testing programme may have a negative impact on athletes’ perception of psychological readiness to return.MethodsA total of 30 athletes who had ACLR and underwent the QMA-RTS 4–10 months after ACLR were recruited. They were randomised to one of two groups that both completed a baseline ACL Return to Sport after Injury (ACL-RSI) scale before their QMA-RTS appointment. In the intervention group, participants completed a second ACL-RSI after the QMA-RTS. In the control group, participants completed their second survey before the session. The mean difference in scores between the two groups was compared using an independent samples t-test.ResultsThe groups were balanced for sex (9/15 female), mean age (16 years) and average time since surgery (6 months). The baseline ACL-RSI scores were not statistically different between groups (4.6 (95% CI −10.6 to 19.8), p=0.54). In the controls, there was an increase in scores (+4.4) between the first and second surveys, while there was a decrease in the intervention group (−3.4). This difference between groups was not statistically significant (7.8 (95% CI −1.7 to 17.3), p=0.10).ConclusionsThe QMA-RTS programme did not significantly reduce patients’ mean scores on the ACL-RSI compared with controls. The limited effect on psychological responses may be due to the athletes’ self-awareness of their physical deficits at 6 months after ACLR.Level of evidenceLevel II, randomised controlled trial.

Background: Preventive training programs (PTPs) reduce injury risk in youth athletes. Corrective verbal feedback is an integral component of PTP implementation; however, too many cues delivered at once may be too complicated for youth athletes. PTPs with simplified cues may be more effective as traditional PTPs to improve athlete injury risk. Hypothesis/Purpose: The purpose of this study was to evaluate changes in movements associated with injury risk youth athletes participating in a season-long PTP: with simplified feedback cues, with traditional feedback cues, or in a warm-up of the coaches’ choosing. Methods: A cluster-randomized controlled trial was utilized. Youth soccer teams were randomized into: simplified or traditional PTP, or the control group. Simplified and traditional PTPs were the same duration (10-15 minutes) with the same exercises, but the simplified PTP only provided sagittal plane feedback cues (e.g., “get low”) and the traditional PTP provided feedback in all planes of motion (e.g., “don’t let your knees cave inward”). Teams in the control group performed their coach’s warm-up. Participants completed two test sessions (PRE-season, POST-season) with three trials of a jump-landing task evaluated using the Landing Error Scoring System (LESS). The LESS is a valid and reliable clinical movement assessment. Participants jumped off a 30-cm high box to a distance half their height and immediately rebounded straight in the air for maximum vertical height. A single, reliable rater graded all trials. Three trials were averaged together for one composite LESS score at each time point. A generalized linear model was used to evaluate differences in composite LESS score between warm-up (Simplified, Traditional, Control) over time (PRE, POST) while controlling for team. All data were analyzed using SPSS Version 21.0 (p<0.05). Results: There were no significant differences between Simplified and Traditional PTPs (P>0.05) so the PTPs were combined into a single group (Intervention) and compared to Control from PRE to POST. Four-hundred and twenty athletes (Intervention n=291 athletes, Control n=129 athletes) participated. The Intervention group improved LESS scores ((Mean±SE [95% CI]) Intervention PRE:6.32±0.17 [5.99,6.67], Intervention POST: 5.36±0.16 [5.05,5.69], Control PRE: 6.58±0.35 [5.94,7.30], Control POST: 6.09±0.34 [5.47,6.79])(P=.04). Conclusion: Regardless of PTP, athletes improved movement technique. These findings suggest that simplified corrective feedback is as effective as more complex feedback. Future studies should look to train coaches to focus on simplified cues and evaluate impact on PTP implementation.

Abstract Background The “FIFA 11 + Shoulder” programme has been reported to reduce the incidence of upper extremity injuries among soccer goalkeepers. It has also been recommended for overhead sports. The purpose of this study was therefore to investigate the effect of an 8-week “FIFA 11 + shoulder” (11 + S) programme on shoulder joint position sense (JPS), threshold to detect passive motion (TTDPM) and upper quarter Y Balance Test in young male volleyball players. Methods Thirty-two healthy young elite male volleyball players (17.49 ± 1.47 years) participated in this quasi-experimental study. Participants, recruited from two clubs participating in Iranian premier league, were randomly assigned into two groups; (1) the intervention group who performed the “FIFA 11 + shoulder” programme as their warm up protocol, three times per week, and (2) the control group who kept their routine warm up protocol meanwhile. Proprioception tests including JPS and TTDPM of internal and external rotator muscles of the dominant shoulder were recorded via the isokinetic system pro 4. The upper quarter Y Balance Test determined the shoulder dynamic stability. Results No statistically significant differences were observed for JPS and TTDPM of shoulder internal and external rotator muscles; shoulder stability however significantly increased only in the intervention group (p = 0.03, ηp2=0.02). Conclusion Upper quarter dynamic stability improvement due to the 11+S programme leads to volleyball players’ performance and may therefore contribute to a reduction in risk of sustaining injury if applied long-term.

BACKGROUND Anterior cruciate ligament reconstruction surgery is one of the most common orthopedic procedures. One of the main factors that influence the outcome is regaining strength in the postoperative phase. Because anterior cruciate ligament reconstruction surgeries are often performed in young patients, we combined the concept of prehabilitation with an app-based serious gaming approach to improve maximal strength postoperatively. OBJECTIVE Our objective was to conduct a prospective randomized trial to evaluate whether an app-based active muscle training program (GenuSport Knee Trainer) can improve postoperative strength by starting rehabilitation immediately after primary anterior cruciate ligament reconstruction surgery. METHODS We designed a pilot study in which we randomly assigned patients receiving primary anterior cruciate ligament reconstruction to either the serious gaming training (intervention) group or a conventional rehabilitation (control) group. Except for the serious gaming-based training, both groups followed the same postoperative treatment protocol. Outcome parameters were absolute and relative change in maximal strength, as well as the International Knee Documentation Committee Subjective Knee evaluation form, Knee Injury and Osteoarthritis Outcome Score, and Lysholm Knee Score. RESULTS In total 26 patients agreed to participate (14 patients in the intervention group and 12 patients in the control group, 1 of whom was lost to follow-up). We noted a difference in absolute maximum strength between the exergaming intervention and the control groups. Mean maximum strength preoperatively was 155.1 (SD 79.2) N in the intervention group (n=14) and 157.0 (SD 40.8) N in the control group (n=11). Postoperative mean maximum strength was 212.8 (SD 78.5) N in the intervention group and 154.5 (SD 27.1) N in the control group. Mean absolute change in maximum strength was 57.7 (SD 95.2) N in the intervention group and –4.8 (22.2) N in the control group. The analysis of covariance model with absolute change as the dependent variable and treatment group and baseline maximum strength as covariates showed a relevant difference in relative change between treatment groups (intervention – control) of 59.7 N (95% CI 10.1-109.3; <i>P</i>=.02). Similarly to the absolute increase, the relative change in maximum strength was relevantly higher in the exergaming group. The mean relative change in maximum strength was 1.7 (SD 1.17) in the intervention group and 1 (SD 0.13) in the control group. No adverse events or problems were reported during the study period. CONCLUSIONS Implementation of an app-based active muscle training program in the early postoperative therapy scheme was associated with an improvement in maximal strength. Therefore, we considered the use of GenuSport training after anterior cruciate ligament reconstruction to be a helpful complement to rehabilitation after anterior cruciate ligament reconstruction surgery to improve strength in the early postoperative phase. To our knowledge this was the first study to analyze immediate postoperative serious gaming-based training with the GenuSport device based on strength improvement.
