Background: The prevalence of youth athletes specializing in 1 sport has been increasing over the past decade. Subsequently, the rate of youth athlete injury has also been increasing. It is possible that an association exists between youth specialization and sports injury rate. Purpose: To determine if sport sampling is associated with a lower sports injury rate in youths compared with youths who specialize in 1 sport. Study Design: Systematic review and meta-analysis. Methods: A systematic review was conducted following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines using PubMed, Embase, and the Cochrane library. Inclusion criteria included studies written in the English language, studies with athletes between 7 and 18 years of age, studies that report injury rates, and studies that specify if athletes were sport samplers or specialized in a sport. Data relevant to this study, including injuries and patient characteristics, were extracted and statistically analyzed. Results: The initial search identified 324 studies, 6 of which met inclusion criteria. From these 6 studies, the total participant number was 5736. Of those, 2451 (42.7%) were “sport samplers,” 1628 (28.4%) were “sport specializers,” and 1657 (28.9%) were considered “others” (ie, could not be classified as true samplers or true specializers). The average age of all the athletes was 14.6 years (range, 7-18 years). Sport specializers had a significantly higher injury risk than the sport samplers (RR, 1.37; 95% CI, 1.19-1.57; P < .0001). There was a higher risk of injury in the “others” group when compared with the “sport sampler” group (RR, 1.21; 95% CI, 1.14-1.29; P < .0001). There was a higher risk of injury in the “sport specializer” group over the “others” group (RR, 1.09; 95% CI, 1.04-1.14; P < .005). Conclusion: Sport sampling is associated with a decreased risk of sports injury in youth athletes when compared with those who specialize in 1 sport. Injury rates increase as a youth athlete becomes increasingly specialized. Youth athletes would benefit substantially from participating in sport sampling.

Background: The prevalence of adolescent athletes who specialize in sports has increased in recent years. Substantial literature on youth sports has linked early sport specialization to negative consequences, such as burnout and injury. However, empirical evidence directly comparing burnout rates in sport specialization versus sport sampling is very limited. Purpose: To conduct a systematic review and meta-analysis to evaluate psychological burnout in adolescent athletes who sport specialize compared with adolescent athletes who sport sample. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review was performed through use of the PubMed, SportDiscus, PsychInfo, and CINAHL databases (between inception and May 2019) according to PRISMA-IPD (Preferred Reporting Items for Systematic Reviews and Meta-Analyses of individual participant data) guidelines. Results from the 3 measures of the Athlete Burnout Questionnaire and athlete specialization status were recorded and analyzed. An athlete was determined to be a “sport specializer” if he or she met the following 3 criteria: (1) athletic participation limited to 1 sport, (2) which is competed in > 8 months in 1 year, and (3) to the exclusion of all other sports. Results: Of 3578 studies, 8 met criteria for final meta-analysis, which included 1429 athletes (mean age, 15.59 years; range, 12.5-17.2 years). Of these, 1371 (95.9%) were sport specializers, whereas 58 (4.1%) were sport samplers. A total of 1422 (99.5%) athletes completed the Athlete Burnout Questionnaire. Athletes who specialized reported higher levels of burnout than athletes who did not specialize. Specializers had a greater sense of reduced accomplishment (difference of means [△], 0.87; 95% CI, 0.67-1.08; P < .01). Specializers also reported greater exhaustion (△, 0.46; 95% CI, 0.24-0.68; P < .01) and sport devaluation (△, 0.41; 95% CI, 0.22-0.60; P < .01) than athletes who were samplers. Conclusion: Adolescent sport specialization was associated with greater levels of burnout in all 3 aspects (reduced sense of accomplishment, sport devaluation, and exhaustion) compared with sport sampling.

Purpose: To compare publicly available rehabilitation protocols designated for meniscal repairs published online to determine the variability in meniscus repair protocols including different types of tears (radial vs nonradial repairs). Methods: From the Fellowship and Residency Electronic Interactive Database Access System (FREIDA), a list of publicly available academic residency programs and orthopaedic sports medicine fellowships was obtained. With this list, an electronic search using Google was performed looking for meniscal repair rehabilitation protocols. In addition to academic institutions, private practice organizations with published meniscus repair rehabilitation protocols found during the search also were examined. Results: Of 189 academic institutions, a total of 30 academic institutions had protocols that were included. Another 29 private practice programs were subsequently found and included. In total, 59 rehabilitation protocols fit the inclusion criteria. Six of the 59 specified radial repair and 53 did not. For return to full range of motion, nonradial protocols averaged 6.7 weeks and radial protocols averaged 7.3 weeks. For return to full weight-bearing, nonradial protocols averaged 6.2 weeks and radial protocols averaged 7.5 weeks. For return to sport, nonradial protocols averaged 17.8 weeks and radial protocols averaged 23.3 weeks. For time spent in a brace, nonradial protocols averaged 5.7 weeks and radial protocols averaged 6.7 weeks. Conclusions: Of publicly available meniscal repair rehabilitation protocols, a small percentage (10.2%) changed their protocol in relation to tear type and there was a wide range of timeframes for each rehabilitation component. Protocols for radial tears tended to brace patients longer, limit their range of motion longer, delay full weight-bearing, and delay return to sport. However, it is recognized that some surgeons could be modifying their protocols in relation to tear type without publishing that information online. Clinical Relevance: As stated in the purpose, the point of this study was to access only the protocols that would be available to the public. If anything, awareness should be raised for surgeons to look at their existing protocols and update them if they are truly incomplete and outdated. More research needs to be done to structure a rehabilitation protocol that is specific to the meniscal tear type, as the current protocols have a wide range of variance.

Introduction. The prevalence of athletes who specialize in sports has increased in recent years. Substantial literature on youth sports has linked early sport specialization to negative consequences, such as burnout and injury. However, empirical evidence comparing rates of burnout and specialization in NCAA athletes is limited. The purpose of this study was to survey current NCAA Division I student-athletes to compare levels of burnout to sex, year of NCAA eligibility, and age at the beginning of sport specialization. Methods. A self-reported survey was distributed to student-athletes at two NCAA Division I institutions, which included demographics, sport specialization history, injury history, and the Athlete Burnout Questionnaire. Results from the three measures of the Athlete Burnout Questionnaire (reduced sense of accomplishment, exhaustion, sport devaluation) were compared to sex, year of NCAA eligibility, age of beginning sport specialization, and injury history. Results. A total of 267 athletes (95 males and 172 females) completed the survey. Of those, 156 (58.4%) were in their first or second year of NCAA eligibility, and 111 (41.6%) were in their third, fourth, or fifth year. Of the total, 121 (46.4%) reported specializing before the age of 15, and 140 (53.6%) specialized at age 16 or older. Females reported significantly higher levels of exhaustion than males (Difference of means (M) = 0.43, 95% confidence interval (CI) = [0.20, 0.66], p < 0.01). Athletes in their third, fourth, or fifth year of eligibility reported significantly higher levels of sport devaluation (M = 0.27, 95% CI = [0.05, 0.48], p < 0.05) than athletes in their first or second year. Athletes who specialized before age 15 did not report significantly higher levels of burnout than athletes who specialized at age 16 or later. In total, 203 athletes (77.2%) reported experiencing any injury. Athletes who reported a history of experiencing any injury demonstrated significantly higher feelings of reduced sense of accomplishment than athletes with no injury history (Difference of means (M) = 0.24, 95% confidence interval (CI) = [0.03, 0.45], p < 0.05). Conclusions. Athletes were more likely to experience elevated levels of burnout if they reported female sex, older NCAA eligibility, or a past injury history. However, athletes were not more likely to experience increased burnout based on age of beginning specialization. The results demonstrated a need to address burnout in athletes following injury and to be aware that females and older athletes are more prone to burnout.
