Yeh, MD, Kerlan-Jobe Orthopaedic Clinic, 6801 Park Terrace, Los Angeles, CA 90045 (e-mail: [email protected]). ─────────────────────────────────────── Background: The current incidence and outcomes of meniscal injury have not been quantified in professional athletes. 背景： 目前半月板损伤的发生率和结果在职业运动员中还没有被量化。 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. 目的： 描述发生率、危险率、损失时间和对美国国家篮球协会（NBA）运动员表现的影响。 Study Design: Descriptive epidemiology study. 研究设计： 描述性流行病学研究。 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 player performance. 方法： 为了监定发生在NBA、超过21个球季的半月板损伤，查询一个集中式资料库。计算受伤、 损失时间、比赛曝光的频率，以及发生率、比率和危险率。受伤前和受伤後的球员效率值 (PER) 被用来监定球员表现的改变。 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. 结果： 一、我们监定在21个球季期间、129例NBA运动员的半月板单独撕裂伤，其中77例 (59.7%) 是发生在外侧半月板，52例 (40.3%) 是发生在内侧半月板。 二、损伤在比赛中较常发生。 三、外侧半月板有较高的受伤率，在统计学有显着差异。 四、左膝和右膝都同样被影响。 五、外侧半月板撕裂伤和内侧半月板撕裂伤缺席天数分别是43.8±35.7天和40.9±29.7 天，两者没有显着差异。 六、年龄和外侧半月板撕裂伤的比率成反比。外侧半月板撕裂伤在30岁前更容易发生；超 过30岁以内侧半月板撕裂伤比较普遍。 七、身体质量指数 (BMI) 大於25的球员和BMI小於25的球员相比，半月板撕裂伤的危险性 有显着增加。 八、25位球员 (19.4%) 并未回到赛场上打球。 九、对於那些伤後立即回来比赛的球员，和受伤前的状态比较，PER在统计学上并无变化， 完整球季的平均数是4.1±3.7个球季。 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. 结论： 一、外侧半月板比内侧半月板更常发生撕裂伤，但是在总上场损失时间并没有什麽不同。 二、右膝和左膝都同样被影响。 三、年龄和外侧半月板撕裂伤的比率成反比。 四、半月板撕裂伤的危险率在BMI大於25的球员中是增加的。 五、半月板损伤对打球表现没有负面影响。 ─────────────────────────────────────── Published online before print November 30, 2011, doi: 10.1177/0363546511428601 Am J Sports Med March 2012 vol. 40 no. 3 589-594 http://tinyurl.com/6v54x6m -- 相关报导 林来疯粉丝福音！复元机率 高达80％ http://www.libertytimes.com.tw/2012/new/apr/2/today-fo7.htm?Slots=TPhoto -- 补充 膝关节的半月板是纤维软骨组织，半月板充填於股骨髁与胫骨髁之间，有增强膝关节稳定 的作用。正是由於半月板所起到的稳定载荷作用，才保证了膝关节长年负重运动而不致损 伤。它是膝关节内最易损伤的组织之一。 对於半月板损伤最理想的治疗方法应该是破裂处缝合，使其癒合。半月板缝合术是所有手 术方式中远期疗效最肯定的治疗方法，是对人体损伤最小、最符合人体正常生物力学的方 法。 http://news.chinatimes.com/wantdaily/11052101/112012040200170.html -- 我的心得 一、半月板损伤的平均休息天数有40多天，在时间上需要耐心等待。 二、用NBA官方登录资料计算，林书豪的BMI小於25，在统计上属於危险率较低的一群。 三、半月板损伤对未来在球场上的表现影响不大，这统计结果令人感到安心。 因为从新闻看到相关的paper，所以就上来分享一下。 不过自己只有看摘要，加上自己不是学医的，所以很多理解的内容都只是片面的而已，如 果有明显错误的地方麻烦帮忙更正。 -- 祝福书豪早日痊癒 --
