Epidemiology of Isolated Meniscal Injury and Its Effect on Performance in Athletes From the National Basketball Association 半月板單獨損傷之流行病學及其在美國國家籃球協會運動員表現之影響 Peter C. Yeh, MD*,＋, Chad Starkey, PhD‡, Stephen Lombardo, MD＋, Gary Vitti, MS, ATC§ and F. Daniel Kharrazi, MD＋ ─────────────────────────────────────── Author Affiliation: ＋ Kerlan-Jobe Orthopaedic Clinic, Los Angeles, California ‡ Ohio University, Athens, Ohio § Los Angeles Lakers, El Segundo, California Investigation performed at Kerlan-Jobe Orthopaedic Clinic, Los Angeles, California * Peter C. Yeh, MD, Kerlan-Jobe Orthopaedic Clinic, 6801 Park Terrace, Los Angeles, CA 90045 (e-mail: pda@aya.yale.edu). ─────────────────────────────────────── Background: The current incidence and outcomes of meniscal injury have not been quantified in professional athletes. 背景：目前半月板損傷的發生率和結果在職業運動員中還沒有被量化。 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：描述發生率、危險率、損失時間和對美國國家籃球協會（NBA）運動員表現的影響。 Study Design: Descriptive epidemiology study. 研究設計：描述性流行病學研究。 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：為了鑑定發生在NBA、超過21個球季的半月板損傷，查詢一個集中式資料庫。計算受傷、損失時間、比賽曝光的頻率，以及發生率、比率和危險率。受傷前和受傷後的球員效率值 (PER) 被用來鑑定球員表現的改變。 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. 結果：一、我們鑑定在21個球季期間、129例NBA運動員的半月板單獨撕裂傷，其中77例 (59.7%) 是發生在外側半月板，52例 (40.3%) 是發生在內側半月板。二、損傷在比賽中較常發生。三、外側半月板有較高的受傷率，在統計學有顯著差異。四、左膝和右膝都同樣被影響。五、外側半月板撕裂傷和內側半月板撕裂傷缺席天數分別是43.8±35.7天和40.9±29.7 天，兩者沒有顯著差異。六、年齡和外側半月板撕裂傷的比率成反比。外側半月板撕裂傷在30歲前更容易發生；超過30歲以內側半月板撕裂傷比較普遍。七、身體質量指數 (BMI) 大於25的球員和BMI小於25的球員相比，半月板撕裂傷的危險性有顯著增加。八、25位球員 (19.4%) 並未回到賽場上打球。九、對於那些傷後立即回來比賽的球員，和受傷前的狀態比較，PER在統計學上並無變化，完整球季的平均數是4.1±3.7個球季。 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. 結論：一、外側半月板比內側半月板更常發生撕裂傷，但是在總上場損失時間並沒有什麼不同。二、右膝和左膝都同樣被影響。三、年齡和外側半月板撕裂傷的比率成反比。四、半月板撕裂傷的危險率在BMI大於25的球員中是增加的。五、半月板損傷對打球表現沒有負面影響。 ─────────────────────────────────────── 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 -- 相關報導林來瘋粉絲福音！復元機率高達80％ http://www.libertytimes.com.tw/2012/new/apr/2/today-fo7.htm?Slots=TPhoto -- 補充膝關節的半月板是纖維軟骨組織，半月板充填於股骨髁與脛骨髁之間，有增強膝關節穩定的作用。正是由於半月板所起到的穩定載荷作用，才保證了膝關節長年負重運動而不致損傷。它是膝關節內最易損傷的組織之一。對於半月板損傷最理想的治療方法應該是破裂處縫合，使其癒合。半月板縫合術是所有手術方式中遠期療效最肯定的治療方法，是對人體損傷最小、最符合人體正常生物力學的方法。 http://news.chinatimes.com/wantdaily/11052101/112012040200170.html -- 我的心得一、半月板損傷的平均休息天數有40多天，在時間上需要耐心等待。二、用NBA官方登錄資料計算，林書豪的BMI小於25，在統計上屬於危險率較低的一群。三、半月板損傷對未來在球場上的表現影響不大，這統計結果令人感到安心。因為從新聞看到相關的paper，所以就上來分享一下。不過自己只有看摘要，加上自己不是學醫的，所以很多理解的內容都只是片面的而已，如果有明顯錯誤的地方麻煩幫忙更正。 -- 祝福書豪早日痊癒 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.41.216.97
