Background:

Meniscal tears, including tears at the root attachment, have been associated with tears of the anterior cruciate ligament (ACL) in both primary and revision settings. However, there is a paucity of literature reporting the healing rates of meniscal repair during 2-stage revision ACL reconstruction (ACLR).

Purpose:

To evaluate the healing rates of meniscal repairs performed during 2-stage revision ACLR in ACL-deficient knees and to report the incidence of meniscus root tears in patients undergoing primary ACLR as compared with revision ACLR.

Study Design:

Case series; Level of evidence, 4.

Methods:

Patients who underwent primary and revision ACLR by a single surgeon were retrospectively identified. Revision ACLRs were grouped according to 1- or 2-stage ACLR. Meniscal tears were grouped according to laterality (medial, lateral) and location of tears. Meniscal repair technique was recorded, including transtibial or inside-out. Meniscal repair healing was assessed via second-look arthroscopy at the time of second-stage revision ACLR.

Results:

There were 1168 patients identified who underwent ACLR: 851 primary and 317 revision procedures. Sixty-four patients underwent meniscal repair during first-stage bone grafting in ACL-deficient knees, with an overall healing rate of 86%. The healing rates were 82.3% for meniscus root tears via the transtibial repair technique and 92.4% for meniscal peripheral tears via the inside-out repair technique. Meniscus root tears had overall incidences of 15.5% and 26.2% in primary and revision ACLRs, respectively. The incidence of lateral meniscus posterior root tears was approximately 4 times higher than of medial meniscus posterior root tears in both primary (12.2% vs 3.2%) and revision (20.5% vs 5.6%) ACLRs.

Conclusion:

A high incidence of meniscus root tears was found in patients undergoing revision ACLRs as compared with primary ACLRs. Meniscal repairs have a high rate of healing and success when performed during the first stage of revision ACLR in ACL-deficient knees.

在两阶段翻修前交叉韧带重建的第一阶段中接受修复的患者半月板​​眼泪的发生率和愈合率。

背景：

半月板撕裂，包括在根部附着处的撕裂，在主要和翻修部位均与前十字韧带（ACL）的撕裂有关。但是，很少有文献报道两阶段修订ACL重建（ACLR）期间半月板修复的治愈率。

目的：

为了评估在ACL缺陷型膝关节的两阶段修订ACLR中进行的半月板修复的治愈率，并报告与原版ACLR相比接受原发ACLR的患者半月板​​根部撕裂的发生率。

学习规划：

案例系列；证据水平4。

方法：

回顾性地确定由一名外科医生接受原发性和修订性ACLR的患者。修订版ACLR根据1级或2级ACLR分组。半月板眼泪根据眼泪的侧向性（内侧，外侧）和位置进行分组。记录了半月板修复技术，包括胫骨或由内而外。在第二阶段修订版ACLR时，通过透视关节镜评估了半月板修复的愈合情况。

结果：

确认有1168例接受了ACLR的患者：851例初次手术和317例修订程序。在ACL缺陷型膝盖的第一阶段植骨过程中，有64例患者接受了半月板修复，总体治愈率为86％。通过胫骨修复技术，半月板根部撕裂的愈合率为82.3％，通过内而外修复技术，半月板周围部撕裂的愈合率为92.4％。半月板根撕裂在原发性和改版ACLR中的总发生率分别为15.5％和26.2％。在原发性ACLR（12.2％vs. 3.2％）和修订版（修订版）（20.5％vs 5.6％）中，外侧半月板后根撕裂的发生率均比内侧半月板后根撕裂的发生率高4倍。

结论：

与原发性ACLR相比，接受改版ACLR的患者中半月板根部撕裂的发生率较高。当在ACL缺陷型膝关节ACLR翻修的第一阶段进行半月板修复时，治愈率和成功率很高。
