“…Knee-sprain rates were also higher in competition than in practice at each competition level. This finding is consistent with the results of previous injury-surveillance studies that identified higher competition injury rates in high school athletics, 22 collegiate athletics, [23][24][25] professional football, 26 and professional soccer. 27,28 The observation highlights the increased intensity of game play that may occur within competitions versus practices.…”

Context: Variations in knee-sprain incidence among competition levels are unclear but may help inform prevention strategies in American football players.Objective: To describe the epidemiology of knee sprains in youth, high school, and collegiate football players.Design: Descriptive epidemiology study. Setting: Injury and athlete-exposure (AE) data were collected from 3 injury-surveillance programs at the youth, high school, and collegiate competition levels.Patients or Other Participants: Data from 310 youth, 184 high school, and 71 collegiate football team-seasons were collected during the 2012 through 2014 seasons.Main Outcome Measure(s): Knee-sprain rates and risks were calculated for each competition level. Injury rate ratios (IRRs) and risk ratios (RRs) compared knee-sprain rates by competition level. Injury proportion ratios (IPRs) compared differences in surgery needs, recurrence, injury mechanism, and injury activity by competition level.Results: Knee-sprain rates in youth, high school, and collegiate football were 0.16/1000 AEs, 0.25/1000 AEs, and 0.69/1000 AEs, respectively. Knee-sprain rates increased as the competition level increased (high school versus youth: IRR ¼ Conclusions: Knee-sprain incidence was highest in collegiate football. However, level-specific variations in the distributions of knee sprains by injury activity may highlight the need to develop level-specific policies and prevention strategies that ensure safe sports play.Key Words: knee injuries, injury surveillance, injury prevention Key PointsThe risk of knee sprains increased as the competition level increased, with the highest risk occurring in collegiate football players. Total knee-sprain rates and the proportion due to being blocked were higher in collegiate than in youth or high school football athletes; however, a smaller proportion of collegiate knee sprains were due to tackling. Level-specific variations in the distributions of knee sprains by injury activity may highlight the need to develop policies and prevention strategies that ensure safe sports play.

“…22 Sports such as soccer, football, and skiing have been reported to be high-risk sports and individuals who participate in these sports are 10 times more likely to rupture the ACL when compared to other sport activities. 23 Even though reconstruction is the most common treatment for ACL rupture, there remains debate in the literature regarding the optimal timing of surgery. 24 Smith et al concluded from their systematic review that there were no differences in clinical outcomes between early (less than 3 weeks) and delayed (greater than 6 weeks) ACL reconstruction (ACLR); however, their conclusion is based on present literature that has limitations, such as non-randomization and lack of appropriate blinding.…”

Functional outcome following arthroscopic ACL reconstruction using semitendinosus graft: a prospective observational study

et al. 2017

Background: Anterior cruciate ligament (ACL) injuries remain a common orthopaedic disease, particularly in young adults. The treatment of choice for ACL injuries is ACL reconstruction (ligamentoplasty). The present study was conducted to observe and evaluate the outcome results of arthroscopic ACL reconstruction by hamstring grafts using Endobutton-CL technique for femoral fixation and Bioabsorbable Intrafix Screw technique for tibial fixation in ACL injury.Methods: This prospective comparative observational study related data were captured between January 2014 to December 2015 in a tertiary care teaching hospital, Haldia. About 36 patients with arthroscopic anatomic ACL reconstruction using hamstring tendon graft were evaluated and followed up for functional outcome. Patients were evaluated for pain, functioning and stability of knee using validated knee scoring systems which included tegner activity scale and IKDC score.Results: Out of 36 patients 31 patients (86.11%) were male and 5 patients (13.88%) were females. About 25 patients (69.44%) had right sided ACL injury and remaining 11 patients (30.55%) had left sided ACL injury. The mean of the pre-op IKDC scoring was 42.45 with SD of 9.68 and the mean of the post-operative IKDC scoring was 81.87 with SD of 13.40, so improvement was statistically significant. Conclusions: The technique of arthroscopic ACL reconstruction offers an excellent knee function, knee stability and restoration of preoperative functional status with minimal complications.

Abstract-Motion analysis technologies have been widely used to monitor the potential for injury and enhance athlete performance. However, most of these technologies are expensive, can only be used in laboratory environments and examine only a few trials of each movement action. In this paper, we present a novel ambulatory motion analysis framework using wearable inertial sensors to accurately assess all of an athlete's activities in real training environment. We firstly present a system that automatically classifies a large range of training activities using the Discrete Wavelet Transform (DWT) in conjunction with a Random forest classifier. The classifier is capable of successfully classifying various activities with up to 98% accuracy. Secondly, a computationally efficient gradient descent algorithm is used to estimate the relative orientations of the wearable inertial sensors mounted on the shank, thigh and pelvis of a subject, from which the flexion-extension knee and hip angles are calculated. These angles, along with sacrum impact accelerations, are automatically extracted for each stride during jogging. Finally, normative data is generated and used to determine if a subject's movement technique differed to the normative data in order to identify potential injury related factors. For the joint angle data this is achieved using a curve-shift registration technique. It is envisaged that the proposed framework could be utilized for accurate and automatic sports activity classification and reliable movement technique evaluation in various unconstrained environments for both injury management and performance enhancement.

Incidence and Risk Factors for Injuries to the Anterior Cruciate Ligament in National Collegiate Athletic Association Football

Abstract: Between 2004 and 2009, NCAA football players experienced a greater number of ACL injuries in games compared with practices, in scrimmages compared with regular practices, and when playing on artificial turf surfaces. This latter finding will need to be confirmed by additional studies.
