Use of microfracture in the knees of National Basketball Association (NBA) players is controversial.
(1) There would be a high rate of return to sport (RTS) in NBA players following microfracture, (2) players would RTS the season following surgery, (3) preoperative player performance would not be significantly different on RTS, and (4) there would be no significant difference in RTS rate or postoperative performance in players undergoing microfracture in comparison with an age-, position-, NBA experience-, and performance-matched control group.
Cohort study; Level of evidence, 3.
NBA players undergoing microfracture were evaluated. Age-, body mass index-, position-, NBA experience-, and performance-matched controls were selected from the NBA during the same years as those undergoing microfracture. An index year was selected (controls) to match the number of seasons of NBA experience in microfracture cases. RTS and performance were analyzed and compared between cases and controls. Student t tests were performed for analysis of within- and between-group variables.
A total of 41 NBA players underwent microfracture and were compared with 41 demographic- and performance-matched controls. Rate of RTS after microfracture was 73% in the NBA and 83% in professional basketball (NBA, D-league, and International Basketball Federation [FIBA]). Time to RTS in NBA was 9.20 ± 4.88 months. Seventy-one percent (29/41) of players RTS the season following microfracture. Length of NBA career following microfracture (4.10 ± 3.91 years) was not significantly different from controls. After microfracture, case athletes played fewer games per season and with fewer points and steals per game (relative to premicrofracture; P < .05). Performance was better in control (after index year) versus case players (after microfracture) with regard to points per game, games played per season, and field goal and free throw percentage (P < .05).
Eighty-three percent of NBA players undergoing microfracture returned to professional basketball. Career length was not significantly different between players undergoing microfracture and controls. However, following microfracture, players competed in fewer games per season with fewer points and steals.
在 NBA 球员的膝关节中使用微骨折术存在争议。
（1）微骨折术后 NBA 球员的运动复出率（RTS）很高，（2）球员将在手术后的赛季复出，（3）术前球员的表现与 RTS 无显著差异，以及（4）与年龄、位置、NBA 经验和表现相匹配的对照组相比，接受微骨折术的球员的 RTS 率或术后表现没有显著差异。
队列研究；证据水平，3 级。
评估接受微骨折术的 NBA 球员。在与接受微骨折术的球员相同的年份，从 NBA 中选择年龄、体重指数、位置、NBA 经验和表现相匹配的对照组。选择一个索引年（对照组）以匹配微骨折病例的 NBA 经验季节数。分析和比较病例和对照组之间的 RTS 和表现。使用学生 t 检验进行组内和组间变量的分析。
共有 41 名 NBA 球员接受了微骨折术，并与 41 名具有相似人口统计学和表现的对照组进行了比较。微骨折术后 RTS 的 NBA 率为 73%，职业篮球（NBA、D 联赛和国际篮球联合会[FIBA]）率为 83%。NBA 中 RTS 的时间为 9.20±4.88 个月。71%（29/41）的球员在微骨折术后的赛季复出。微骨折术后 NBA 职业生涯（4.10±3.91 年）与对照组无显著差异。接受微骨折术后，病例运动员每赛季比赛场次和每场比赛得分和抢断次数减少（与微骨折前相比；P<.05）。与接受微骨折术的病例运动员相比（接受微骨折术后），对照组（在索引年后）在每场比赛得分、每赛季比赛场次和投篮命中率和罚球命中率方面表现更好（P<.05）。
83%接受微骨折术的 NBA 球员重返职业篮球。接受微骨折术和对照组的球员之间的职业生涯长度没有显著差异。然而，接受微骨折术后，球员每赛季的比赛场次减少，得分和抢断次数减少。
