纳入标准:

1: 接受过关节镜下前交叉韧带重建术,包含单纯ACLR以及其它合并术式; 2: 关于“前叉小助手”微信小程序完成术后膝关节屈曲角度自报随访; 3: 至少完成1次术后屈曲角度记录,且若只存在一次术后屈曲角度记录,此次角度值不为180度; 4: 术后屈曲角度测量日期应等于或晚于手术日期。若出现“测量日期 - 手术日期 < 0 天”的记录,视为时间逻辑错误,予以排除。 5: 在总体膝关节屈曲角度轨迹分析集的纳入基础上,规范填写性别、年龄、损伤时间、手术时间、手术类型等信息。

Inclusion criteria

1: Undergone anterior cruciate ligament reconstruction under arthroscopy, including isolated ACLR and other combined surgical procedures; 2: Regarding the completion of postoperative knee flexion angle self-reported follow-up through the 'Fork Little Helper' WeChat Mini Program; 3: At least one postoperative flexion angle record must be completed, and if there is only one postoperative flexion angle record, this angle value should not be 180 degrees. 4: Based on the inclusion of the overall knee flexion angle trajectory analysis set, standardly fill in information such as gender, age, injury duration, surgery time, and type of surgery. 5: On the basis of inclusion in the overall knee flexion angle trajectory analysis set, standardly fill in information such as gender, age, injury duration, surgical time, and type of surgery.

排除标准:

1: 进行其它膝关节术式,没有进行ACLR; 2: 其他膝关节疾病:如有其他膝关节疾病,如严重的骨性关节炎、膝关节感染等; 3: 严重全身性疾病:如心血管疾病、糖尿病等不稳定的慢性疾病; 4: 基线填写信息无法识别,不纳入统计分析。 5: 在总体膝关节屈曲角度轨迹分析集的纳入基础上,未规范填写性别、年龄、损伤时间、手术时间、手术类型等信息。

Exclusion criteria:

1: Undergo other knee surgical procedures without ACLR; 2: Other knee joint diseases: If there are other knee joint diseases, such as severe osteoarthritis, knee joint infection, etc. 3: Severe systemic diseases: such as unstable chronic diseases like cardiovascular diseases and diabetes; 4: Baseline information cannot be recognized and is not included in the statistical analysis. 5: Based on the inclusion of the overall knee joint flexion angle trajectory analysis set, information such as gender, age, injury duration, surgical time, and surgical type was not filled out in a standardized manner.

测量指标:

Outcomes:

指标中文名:

膝关节屈曲角度

指标类型:

主要指标

Outcome:

Knee flexion angle

Type:

Primary indicator

测量时间点:

前交叉韧带重建术后一年时间内,具体时间点不做限制。

测量方法:

采用以下标准化流程进行膝关节屈曲角度测量:患者将手术侧膝关节置于最大屈曲位置,使用智能手机拍摄或上传相应照片;随后,在程序界面中手动以膝关节为中心点,画出两条与大腿及小腿相平行的线,程序以预估的膝关节旋转中心为原点,自动计算两线夹角,并输出膝关节屈曲内角度数。

Measure time point of outcome:

Within one year after anterior cruciate ligament reconstruction, with no specific time points restricted.

Measure method:

The following standardized procedure is used to measure the knee flexion angle: The patient places the surgical side knee in maximum flexion. A smartphone is used to take or upload a corresponding photo. Subsequently, in the program interface, two lines are manually drawn with the knee joint as the center point, parallel to the thigh and the leg respectively. The program calculates the angle between the two lines automatically, using the pre-estimated knee joint rotation center as the origin, an
