In the Original Investigation titled “Effect of Early Surgery vs Physical Therapy on Knee Function Among Patients With Nonobstructive Meniscal Tears: The ESCAPE Randomized Clinical Trial,”1 published in the October 2, 2018, issue, the number of available participants for primary analysis for the physical therapy group should have been listed as 148 instead of 141. In addition, the upper limits of 95% CIs were incorrectly reported as positive rather than negative numbers in Table 3. The between-group differences for the arthroscopic partial meniscectomy vs physical therapy groups overall, at 6 months, and at 24 months should have been reported as −5.9 (95% CI, −10.3 to −1.4), −8.2 (95% CI, −14.1 to −2.3), and −7.7 (95% CI, −14.0 to −1.3) points, respectively. Also, the P values for the between-group difference for the delayed arthroscopic partial meniscectomy vs physical therapy group at 6 months and 24 months should have been .009 and .01, respectively. This article was corrected online.
