A retrospective study to compare the clinical effects of individualized anatomic single- and double-bundle anterior cruciate ligament reconstruction surgery

Abstract

To evaluate the clinical efficacy of single- and double- bundle individualized anatomic anterior cruciate ligament (ACL) reconstruction, we retrospectively analyzed the data and charts of 920 patients with ACL rupture who received individualized anatomic ACL reconstruction surgery at our center. All of the patients underwent arthroscopic ACL reconstruction with autologous hamstring tendons. The patients were divided into two groups: the single-bundle individualized anatomic reconstruction group (N = 539), and the double-bundle individualized anatomic reconstruction group (N = 381). The IKDC, Lysholm and Tegner scores were used to subjectively evaluate the function of the knee joint during the postoperative follow-up. The Lachman test, pivot shift test and KT-3000 were used to objectively evaluate the stability of the knee. All 920 patients participated in clinical follow-up (average duration: 27.91 ± 3.61 months) achieved satisfied outcomes with few complications. The postoperative IKDC, Lysholm and Tegner scores, and the objective evaluation of knee joint stability were significantly improved compared to the preoperative status in both groups (P < 0.05). No statistically significant difference was observed between the two groups at the final follow-up (P > 0.05). Therefore, no difference in terms of the IKDC, Lysholm and Tegner score, or KT-3000 was observed between the individualized anatomic single- and double-bundle ACL reconstruction techniques. Both techniques can be used to restore the stability and functionality of the knee joint with satisfactory short-term efficacy.

Arthroscopic reconstruction of anterior cruciate ligaments with allograft: single-tunnel single-bundle versus single-tunnel double-bundle techniques

“…2 A). In accordance with our previous publication [ 2 ], both the lateral intercondylar ridge and the lateral bifurcate ridge were important bony landmarks for the femoral attachments of the ACL. The femoral tunnel, which should not surpass the lateral intercondylar ridge, was created in the center of the lateral bifurcate ridge.…”

“…The anterior cruciate ligament (ACL) is the main stabilizing structure of the knee; it resists anterior translation and maintains forward and rotational stability [ 1 ]. The ACL is generally considered to include two functional bundles, i.e., the anteromedial (AM) and posterolateral (PL) bundles, each having a unique function [ 2 , 3 ]. The AM bundle and PL bundle provide anteroposterior and rotational stability to the knee joint [ 4 ].…”

Graft Signal and Clinical Outcomes of Single-bundle Anterior Cruciate Ligament Reconstruction and Double-bundle ACLR: The Different Effects Related with Posterior Tibial Slope

“…Presently, although the number of studies comparing the advantages and disadvantages of SB-ACLR and DB-ACLR is gradually increasing, the results remain controversial. [13][14][15][16]] Some researchers believe that DB-ACLR was better at controlling the rotational stability of knee joints and maintaining the health of cartilage due to the restoration of normal ACL structure. [17][18][19] Moreover, the role of MRI-based predictors in ACLR may vary due to different surgical methods, which requires further research.…”

Arthroscopic reconstruction of anterior cruciate ligaments with allograft: Single-tunnel double-bundle versus single-tunnel single-bundle

“…Anterior cruciate ligament (ACL) is the main stabilizing structure of the knee, which resists to the anterior translation and maintains the forward and rotating stabilities [1,2]. It is generally considered to include two functional bundles; the anteromedial (AM) and the posterolateral (PL) bundles, and each of the two primary ACL bundles has a unique function [3,4].…”
