[m 作者 ntu6655 () 看板 Jeremy_Lin 标题 [闲聊] Epidemiology of Isolated Meniscal Inju 时间 Sun Apr 1 09:26:52 2012 ─────────────────────────────────────── http://ajs.sagepub.com/content/early/2011/11/30/0363546511428601.abstract Abstract Background: The current incidence and outcomes of meniscal injury have not been quantified in professional athletes. Purpose: To describe the incidence, risk, amount of time lost, and effect on performance for isolated meniscal injury in athletes from the National Basketball Association (NBA). Demographic factors predicting the risk of meniscal tears and the effect of injury in return to play were also investigated. Study Design: Descriptive epidemiology study. Methods: A centralized database was queried to identify meniscal injuries occurring in the NBA over 21 seasons. The frequency of injury, time lost, game exposures, and incidence, rate, and risk were calculated. The preinjury and postinjury player efficiency rating (PER) was used to identify changes in Results: We identified 129 isolated meniscal tears in NBA athletes during a 21-season span. From this number, 77 (59.7%) involved the lateral meniscus and 52 (40.3%) the medial meniscus. Injuries occurred more frequently in games. The lateral meniscus had a statistically significant higher injury rate. Both left and right knees were equally affected. The number of days missed for lateral meniscal tears and medial meniscal tears was 43.8 ± 35.7 days and 40.9 ± 29.7 days, respectively, and was not statistically different. There was a significant inverse relationship between age and rate of lateral meniscal tears, with lateral meniscal tears more likely to occur up to age 30 years; beyond that medial meniscal tears were more common. Players with a body mass index (BMI) greater than 25 had a significantly increased risk of meniscal tears compared with players with a BMI less than 25, specifically with an increased risk of lateral meniscal tears. Twenty-five players (19.4%) did not return to play. For those who did, upon returning to competition, there was no statistical change in PER from their preinjury status, and the mean number of seasons completed was 4.1 ± 3.7 seasons. Conclusion: The lateral meniscus is more frequently torn than the medial meniscus, but there was no difference in the amount of playing time lost. Both right and left knees were equally affected. There was an inverse relationship between age and the rate of lateral meniscal tears. Risk of tears was increased in players having a BMI greater than 25. Injury did not negatively affect playing performance. -- 书豪有可能成为19.4%吗? 事由：我所谓的唱衰， 第一、原文最後之评论,且外电消息没有附上翻译。 第二、再故意转录简易翻译并在推文试图挑起板面争端。 依据推文试图引起板面争端，原判三个月。 该判只判其推文内文引战，故依据犯行判定，水桶两周。 --
