排除标准: |
1. 需额外手术的多韧带膝关节损伤(如合并III级MCL或PCL损伤需重建)。半月板撕裂等轻微合并损伤不排除(可同期进行半月板修复或清理),但复杂膝关节脱位除外。 2. 中重度膝骨关节炎或可能影响隧道定位的骨畸形(如通常需截骨术的对线不良)。 3. 慢性ACL损伤(受伤>6个月)或组织质量差需考虑原发性修复的撕裂(该年龄段罕见),本研究聚焦急性/新近损伤。 4. 曾接受可能干扰导板放置或混淆结果的患膝手术(如既往ACL重建、胫骨平台骨折内固定)。 5. CT扫描禁忌证(如妊娠期女性因辐射暴露排除;注:本研究CT扫描通常无需造影剂,故造影剂过敏者不适用)。 6. 存在手术/麻醉禁忌的全身性疾病(如未控制糖尿病、活动性感染、凝血障碍)或影响康复的病症(如严重神经功能缺损)。 7. BMI>35(病态肥胖),因过度脂肪可能干扰导板精准贴合或改变手术技术(此阈值具一定主观性,主要考量极端解剖变异)。 8. 拒绝或无法签署知情同意书/遵守随访计划。 |
||||||||||||||||||||||||||||||||||||||||||||
|
Exclusion criteria: |
1. Multi-ligament knee injuries requiring additional surgery (e.g., combined Grade III MCL or PCL injuries requiring reconstruction). Minor combined injuries such as meniscal tears are not excluded (meniscal repair or debridement can be performed at the same time), but complex knee dislocations are excluded. 2. Moderate to severe knee osteoarthritis or bone deformity that may affect tunnel positioning (such as malalignment that usually requires osteotomy). 3. Chronic ACL injuries (injury > 6 months) or poor tissue quality require consideration of primary repair tears (rare in this age group). This study focuses on acute/recent injuries. 4. Previous knee surgery that may interfere with guide plate placement or confound the results (such as previous ACL reconstruction, tibial plateau fracture internal fixation). 5. Contraindications for CT scanning (e.g., pregnant women are excluded due to radiation exposure; Note: CT scanning in this study usually does not require contrast agents, so it is not suitable for those who are allergic to contrast agents). 6. Systemic diseases that are contraindications to surgery/anesthesia (such as uncontrolled diabetes, active infection, coagulation disorders) or conditions that affect recovery (such as severe neurological deficits). 7. BMI > 35 (morbidly obese), as excess fat may interfere with the precise fit of the guide or alter the surgical technique (this threshold is somewhat subjective and primarily considers extreme anatomical variations). 8. Refusal or inability to sign informed consent/comply with follow-up schedule. |

随机方法(请说明由何人用什么方法产生随机序列): |
符合条件且签署同意的患者将通过计算机生成随机序列(采用随机块区组设计,如4或6例/块)按1:1比例分配至3D导板组或对照组。鉴于样本量有限,暂不进行分层随机(若发现慢性损伤或性别等关键混杂因素,可后续补充分层)。独立统计师制备随机序列以确保不可预测性。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Eligible and consenting patients will be assigned in a 1:1 ratio to either the 3D guide group or the control group using a computer-generated random sequence (block randomization design with block sizes of 4 or 6). Given the limited sample size, stratified randomization will not be performed at this stage; however, if key confounding factors such as chronic injury or sex are identified, stratification may be added later. The random sequence will be prepared by an independent statistician to ensure unpredictability. |

|
盲法: |
受试者盲法:不告知具体分组。两组术前流程相似(均行MRI,部分接受CT),术中患者处于麻醉状态无法观察器械,术后切口与护理流程完全相同(导板通过关节镜使用无需额外切口)。要求临床团队及物理治疗师保密导板类型。研究结束时通过问卷调查评估盲法效果。 评估者盲法:结局评估人员不知晓分组情况。 术者盲法:因操作性质无法实施(必须知晓是否使用3D导板)。 |
|
Blinding: |
Blinding of Participants: Participants were not informed of their specific group assignments. Preoperative procedures were similar in both groups (all underwent MRI, with some receiving CT). During surgery, patients were under anesthesia and could not observe the instruments. Postoperative incisions and nursing procedures were identical (the guide was applied arthroscopically without an additional incision). The clinical team and physical therapists were instructed to maintain confidentiality regarding the type of guide. A questionnaire was administered at the end of the study to assess the effectiveness of the blinding. Assessor blinding: Outcome assessors were unaware of group assignment. Operator blinding: Unable to be performed due to the nature of the procedure (operator blinding must be known whether a 3D guide is used). |
