Avoidance of Soccer Injuries with Preseason Conditioning

Abstract: The effect of a preseason conditioning program was studied to evaluate its influence on the occurrence and severity of soccer injuries. Three hundred female soccer players (ages 14 to 18 years) were studied over a 1-year period. Forty-two of these players participated in a 7-week training program before the start of the season. The type, mechanism, and severity of the injury, when the injury occurred, the number of games or practices missed, and type of shoe worn were recorded. All injuries occurred in the lower extremities, with 61.2% occurring at the knee and ankle. Student's t-test evaluations revealed that the trained group experienced a significantly lower incidence of injury than the untrained group (P = 0.0085). Although not statistically significant, the trained group also had a lower percentage (2.4%) of anterior cruciate ligament injuries compared with the untrained group (3.1%). These results suggest that this type of conditioning has a significant influence on lowering the incidence of injury in female adolescent soccer players.

Revision Anterior Cruciate Ligament Reconstruction with a Reharvested Ipsilateral Patellar Tendon

Abstract: The patellar tendon remains the most popular graft choice for anterior cruciate ligament reconstruction and has been proven to be the strongest substitute. Between 1991 and 1998, we performed revision anterior cruciate ligament reconstruction using the reharvested central third of the ipsilateral patellar tendon in 15 patients. Adequate follow-up was obtained in 13 of these 15 patients. The results in these 13 patients (mean age, 27.2 years) were reviewed. At an average postoperative follow-up of 39.4 months (range, 24 to 65), 11 patients had good or excellent results and 2 patients had fair results. Clinical examination revealed an average Tegner knee score of 5.8 (range, 3 to 9) and an average Lysholm knee score of 77.6 (range, 61 to 98). Postoperative KT-1000 arthrometer results showed an average side-to-side difference of 1.92 mm (range, -2.0 to 4.0). No patient demonstrated any loss of range of motion and only one reported patellofemoral problems, which were moderate. These favorable results demonstrate that, with appropriate patient selection, the use of a reharvested central third patellar tendon is a viable option for revision of a failed anterior cruciate ligament reconstruction.

Arthroscopic Laser-Assisted Capsular Shift in the Treatment of Patients with Multidirectional Shoulder Instability

Abstract: BackgroundIn recent years, various investigators have begun using lasers in the treatment of shoulder instability.HypothesisArthroscopic laser-assisted capsular shift is an effective treatment for patients with multidirectional shoulder instability.Study DesignRetrospective cohort study.MethodsWe retrospectively identified 28 patients (30 shoulders) with multidirectional shoulder instability who were unresponsive to nonoperative management and who had undergone the laser-assisted capsular shift procedure. Twenty-five patients (27 shoulders) with an average follow-up of 28 months were available for review. All patients underwent a physical examination and completed a general questionnaire; the University of California, Los Angeles, shoulder rating scale; the Western Ontario Shoulder Instability Index; and the Short-Form 36 quality of life index.ResultsIn 22 shoulders, results of the procedure were considered a success because the patients had no recurrent symptoms and at latest follow-up had required no fu...

Acute traumatic first-rib fracture in the contact athlete: a case report.

Abstract: are a rare entity. Isolated first-rib fracture in the trauma patient is well described in trauma and thoracic literature, and there is much literature on stress fracture of the first rib in association with baseball, rowing, weight lifting, dance, tennis, surfing, basketball, and gymnastics. However, there have been only 2 published reports in the past 14 years of acute first-rib fracture in contact athletes. Both cases were secondary to football injuries and were reported by Barrett et al, who described their management of the 2 cases in 1988. Fracture of the first rib sustained during contact sports differs significantly from the more widely reported stress fracture, which occurs as a result of repetitive microtrauma in weakened bone. In contact athletes, the first-rib fracture occurs as a single, acute event in normal bone, the most common area of fracture being in the shallow depression for the subclavian artery, a well-described area of anatomical weakness. In this article, we present another case of a traumatic first-rib fracture sustained by a football player after a collision injury. We also review the pertinent anatomy, biomechanics, and complications associated with the injury.

Simultaneous ACL and PCL reconstruction.

Abstract: The results of 11 patients who underwent simultaneous arthroscopically assisted anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) reconstruction for acute (n=7) or chronic (n=4) multiligamentous knee injuries were reviewed. Seven patients were treated with a bone-patellar tendon-bone (BPTB) autograft for the ACL reconstruction and an Achilles allograft for the PCL reconstruction, three patients with ipsilateral/contralateral BPTB autografts, and one patient with BPTB allograft for ACL and Achilles allograft for PCL. Seven patients were operated on acutely (<3 months postinjury), and 4 were treated for chronic conditions. At follow-up, all patients were subjectively and functionally evaluated with a Lysholm Knee Scoring Scale. Average patient age at surgery was 29 years, and average postoperative follow-up was 28.4 months. Average postoperative Lysholm score was 87.7 (range: 49-100). Four of 11 patients reported occasional mild pain, 2 occasional swelling, and 4 infrequent instability. No patient required a postoperative manipulation to regain his or her range of motion and 10 of the 11 returned to their previous activity level postoperatively. Of the 10 patients able to return for clinical examination, 2 demonstrated a loss of flexion <5 degrees compared to the other side, 7 demonstrated a mild postoperative posterior drawer at 90 degrees (6 at 1+, 1 at 2+), 3 demonstrated a positive Lachman (grade 1), whereas no patient demonstrated any posterior lateral corner instability. The average anterior active difference on KT-1000 was 2.6 (range: 0-6). Simultaneous reconstruction of the ACL and PCL, although technically difficult, is feasible and yields good to excellent functional results.

Descriptive epidemiology of collegiate men's football injuries: National Collegiate Athletic Association Injury Surveillance System, 1988-1989 through 2003-2004

Abstract: Objective: To review 16 years of National Collegiate Athletic Association injury surveillance data for women’s lacrosse and identify potential areas for injury prevention initiatives. Background: Women’s lacrosse is a fast-paced, primarily noncontact sport. Participation in collegiate women’s lacrosse almost doubled between the 1988–1989 and 2003–2004 seasons. Lacrosse equipment consists of sticks made of wood or a synthetic material and a hard rubber ball. Until recently, mouth guards were the only required protective equipment. Main Results: Collegiate women’s lacrosse game injury rates increased over the 16-year study period. More than 60% of all severe game injuries were lower extremity sprains and strains and knee internal derangements, most frequently the result of noncontact incidents. The most common injury scenarios by injury mechanism and player activity were no contact while ball handling (16.4%) and contact from a stick while ball handling (10.5%). Contact from a stick or a ball accounted for 5.6% and 5.2% of injuries sustained during shooting activities, respectively. Approximately 22% of all game and 12% of all practice injuries involved the head and neck. Contact from a stick accounted for the majority (56.0%) of above-the-neck injuries in games; contact from the ball accounted for 20.0% of these injuries. Participants had 5 times the risk of sustaining a concussion in a game as in a practice (0.70 versus 0.15 injuries per 1000 athletic-exposures, rate ratio 4.7, 95% confidence interval 3.8, 6.5). Recommendations: To reduce the lower extremity injuries that comprise the greatest injury burden in women’s lacrosse, future researchers should evaluate proprioceptive, plyometric, and balance training interventions designed specifically for female players. Other research areas of great interest involve determining whether protective eyewear (mandated in 2004) reduces injuries to the eye, orbit, and nasal area and identifying any unintended consequences of the mandate, such as increased risk of injuries to other areas of the face or more aggressive play.

Effectiveness of a Neuromuscular and Proprioceptive Training Program in Preventing Anterior Cruciate Ligament Injuries in Female Athletes 2-Year Follow-up

Abstract: Background: Among female athletes it has not been established whether a neuromuscular and proprioceptive sports-specific training program will consistently reduce the incidence of anterior cruciate ligament injuries.Purpose: To determine whether a neuromuscular and proprioceptive performance program was effective in decreasing the incidence of anterior cruciate ligament injury within a select population of competitive female youth soccer players.Study Design: Cohort study; Level of evidence, 2.Methods: In 2000, 1041 female subjects from 52 teams received a sports-specific training intervention in a prospective non-randomized trial. The control group consisted of the remaining 1905 female soccer players from 95 teams participating in the same league who were age and skill matched. In the 2001 season, 844 female athletes from 45 teams were enrolled in the study, with 1913 female athletes (from 112 teams) serving as the age- and skill-matched controls. All subjects were female soccer players between the ages...

Understanding and Preventing Noncontact Anterior Cruciate Ligament Injuries A Review of the Hunt Valley II Meeting, January 2005

Abstract: The incidence of noncontact anterior cruciate ligament injuries in young to middle-aged athletes remains high. Despite early diagnosis and appropriate operative and nonoperative treatments, posttraumatic degenerative arthritis may develop. In a meeting in Atlanta, Georgia (January 2005), sponsored by the American Orthopaedic Society for Sports Medicine, a group of physicians, physical therapists, athletic trainers, biomechanists, epidemiologists, and other scientists interested in this area of research met to review current knowledge on risk factors associated with noncontact anterior cruciate ligament injuries, anterior cruciate ligament injury biomechanics, and existing anterior cruciate ligament prevention programs. This article reports on the presentations, discussions, and recommendations of this group.

Understanding injury mechanisms: a key component of preventing injuries in sport

Abstract: Anterior cruciate ligament (ACL) injuries are a growing cause of concern, as these injuries can have serious consequences for the athlete with a greatly increased risk of early osteoarthrosis. Using specific training programmes, it may be possible to reduce the incidence of knee and ankle injuries. However, it is not known which programme components are the key to preventing knee and ankle injuries or how the exercises work to reduce injury risk. Our ability to design specific prevention programmes, whether through training or other preventive measures, is currently limited by an incomplete understanding of the causes of injuries. A multifactorial approach should be used to account for all the factors involved-that is, the internal and external risk factors as well as the inciting event (the injury mechanism). Although such models have been presented previously, we emphasise the need to use a comprehensive model, which accounts for the events leading to the injury situation (playing situation, player and opponent behaviour), as well as to include a description of whole body and joint biomechanics at the time of injury.

Youth resistance training: updated position statement paper from the national strength and conditioning association.

Abstract: Faigenbaum, AD, Kraemer, WJ, Blimkie, CJR, Jeffreys, I, Micheli, LJ, Nitka, M, and Rowland, TW. Youth resistance training: Updated position statement paper from the National Strength and Conditioning Association. J Strength Cond Res 23(5): S60-S79, 2009-Current recommendations suggest that school-aged youth should participate daily in 60 minutes or more of moderate to vigorous physical activity that is developmentally appropriate and enjoyable and involves a variety of activities (). Not only is regular physical activity essential for normal growth and development, but also a physically active lifestyle during the pediatric years may help to reduce the risk of developing some chronic diseases later in life (). In addition to aerobic activities such as swimming and bicycling, research increasingly indicates that resistance training can offer unique benefits for children and adolescents when appropriately prescribed and supervised (). The qualified acceptance of youth resistance training by medical, fitness, and sport organizations is becoming universal ().Nowadays, comprehensive school-based programs are specifically designed to enhance health-related components of physical fitness, which include muscular strength (). In addition, the health club and sport conditioning industry is getting more involved in the youth fitness market. In the U.S.A., the number of health club members between the ages of 6 and 17 years continues to increase () and a growing number of private sport conditioning centers now cater to young athletes. Thus, as more children and adolescents resistance train in schools, health clubs, and sport training centers, it is imperative to determine safe, effective, and enjoyable practices by which resistance training can improve the health, fitness, and sports performance of younger populations.The National Strength and Conditioning Association (NSCA) recognizes and supports the premise that many of the benefits associated with adult resistance training programs are attainable by children and adolescents who follow age-specific resistance training guidelines. The NSCA published the first position statement paper on youth resistance training in 1985 () and revised this statement in 1996 (). The purpose of the present report is to update and clarify the 1996 recommendations on 4 major areas of importance. These topics include (a) the potential risks and concerns associated with youth resistance training, (b) the potential health and fitness benefits of youth resistance training, (c) the types and amount of resistance training needed by healthy children and adolescents, and (d) program design considerations for optimizing long-term training adaptations. The NSCA based this position statement paper on a comprehensive analysis of the pertinent scientific evidence regarding the anatomical, physiological, and psychosocial effects of youth resistance training. An expert panel of exercise scientists, physicians, and health/physical education teachers with clinical, practical, and research expertise regarding issues related to pediatric exercise science, sports medicine, and resistance training contributed to this statement. The NSCA Research Committee reviewed this report before the formal endorsement by the NSCA.For the purpose of this article, the term children refers to boys and girls who have not yet developed secondary sex characteristics (approximately up to the age of 11 years in girls and 13 years in boys; Tanner stages 1 and 2 of sexual maturation). This period of development is referred to as preadolescence. The term adolescence refers to a period between childhood and adulthood and includes girls aged 12-18 years and boys aged 14-18 years (Tanner stages 3 and 4 of sexual maturation). The terms youth and young athletes are broadly defined in this report to include both children and adolescents.By definition, the term resistance training refers to a specialized method of conditioning, which involves the progressive use of a wide range of resistive loads and a variety of training modalities designed to enhance health, fitness, and sports performance. Although the term resistance training, strength training, and weight training are sometimes used synonymously, the term resistance training encompasses a broader range of training modalities and a wider variety of training goals. The term weightlifting refers to a competitive sport that involves the performance of the snatch and clean and jerk lifts.This article builds on previous recommendations from the NSCA and should serve as the prevailing statement regarding youth resistance training. It is the current position of the NSCA that:
