Most people have not returned to their preinjury level of sports participation at 12 months after anterior cruciate ligament (ACL) reconstruction surgery. Twelve months' follow-up may be too early to assess return-to-sport outcomes accurately.
This study was undertaken to evaluate the medium-term return-to-sport outcomes after ACL reconstruction surgery.
Case series; Level of evidence, 3.
A self-report questionnaire was used to collect data at 2 to 7 years after ACL reconstruction surgery regarding preinjury sports participation, postoperative sports participation, and subjective knee function. The main inclusion criteria were participation in regular sports activity before injury and the attendance at routine surgical follow-up appointments.
A total of 314 participants (mean age, 32.5 ± 10.2 years) were included at a mean 39.6 ± 13.8 months after ACL reconstruction surgery. At follow-up, 45% were playing sport at their preinjury level and 29% were playing competitive sport. Ninety-three percent of the study sample had attempted sport at some time after their ACL reconstruction surgery. Those who had not attempted their preinjury level of sport by 12 months after surgery were just as likely to have returned to preinjury level by 39 months after surgery as those who had played sport by 12 months (risk ratio, 1.1; 95% confidence interval, 0.76-1.6).
Less than 50% of the study sample had returned to playing sport at their preinjury level or returned to participating in competitive sport when surveyed at 2 to 7 years after ACL reconstruction surgery. Return to the preinjury level of sport at 12 months after surgery was not predictive of participation at the preinjury level in the medium term, which suggests that people who return to sport within 12 months may not maintain their sports participation.
大多数人在前交叉韧带（ACL）重建手术后 12 个月尚未恢复到受伤前的运动参与水平。12 个月的随访可能为时过早，无法准确评估重返运动的结果。
本研究旨在评估 ACL 重建手术后的中期重返运动结果。
病例系列；证据水平，3 级。
使用自我报告问卷，在 ACL 重建手术后 2 至 7 年收集有关术前运动参与、术后运动参与和主观膝关节功能的数据。主要纳入标准是受伤前参与常规运动活动和常规手术随访预约。
共有 314 名参与者（平均年龄 32.5±10.2 岁）在 ACL 重建手术后平均 39.6±13.8 个月时纳入研究。随访时，45%的人运动水平达到受伤前水平，29%的人参加竞技运动。93%的研究样本在 ACL 重建手术后的某个时间尝试过运动。在手术后 12 个月时仍未尝试达到受伤前运动水平的患者，与在手术后 12 个月时已参加运动的患者一样，在手术后 39 个月时恢复到受伤前运动水平的可能性相同（风险比，1.1；95%置信区间，0.76-1.6）。
在 ACL 重建手术后 2 至 7 年进行调查时，研究样本中不到 50%的人恢复到受伤前的运动水平或恢复到参加竞技运动。手术后 12 个月时恢复到受伤前的运动水平并不能预测中期的运动参与水平，这表明在 12 个月内恢复运动的人可能无法保持其运动参与度。
