“…Non-contact mechanism of failure is the most common cause accounting for almost 70% of the ACL injuries, with females reported to have a 2-8-fold greater risk of ACL failure due to the non-contact mechanism. [12,13,24,25] However, in our study of failed primary ACLR, all recorded patients were male. Our study's failure due to contact mechanism accounted for 70%, contrary to the published studies of failure mechanism in native ACL.…”

“…Age, mechanism of failure, delay in surgery, and associated chondral defects are reported to impact the functional outcome of ACLR. [10][11][12] However, it is worth studying if the same holds true for the revision ACLR outcome. We hypothesized that the mechanism of injury, associated chondral defects, and increased time duration between primary and revision surgeries would adversely impact the outcome of revision ACLR.…”

Objectives: The outcome of revision anterior cruciate ligament reconstruction (ACLR) is inferior to that of the primary reconstruction and is influenced by multiple factors. The purpose of this study was to identify the better autograft suited for revision ACLR and to assess the factors influencing the outcome of revision. Methods: A total of 102 patients who underwent revision ACLR were enrolled in this study. The patients were grouped based on the type of autograft used for revision. The mechanism of injury and the cause of the primary ACLR failure, meniscal, and chondral status were noted. All patients’ Tegner Lysholm functional scores were assessed at 2 years of follow-up. Results: Almost 37.3% of the patients underwent revision ACLR with bone-patellar tendon bone, 41.3% with semitendinosus-gracilis, and 21.3% with quadriceps tendon autografts. The mean Tegner-Lysholm score was 85.4 ± 15.8, with the majority achieving good to excellent scores. Chondral defect of Grade 3/4 was associated with an inferior poorer functional outcome (P = 0.03). At a 2-year follow-up, the non-contact mechanism of primary ACLR failure was associated with worse scores compared to the contact mechanism of failure (P = 0.03). On comparison of Lysholm functional score between different autografts using the Kruskal-Wallis test, the p-value was insignificant (P = 0.9). Conclusion: Non-contact mechanism of primary ACLR failure and Grade 3/4 chondral defects was associated with a poorer functional outcome at 2 years post-revision ACLR. The overall functional outcome of revision ACLR was good to excellent in our Middle East Asian population, with no one autograft found to be superior to the other.

“…Dynamic knee valgus is a mechanism that contributes to noncontact injuries (tibial external rotation, knee valgus, and femoral internal rotation). It is believed that inadequate neuromuscular regulation of the hip and trunk muscles is the cause of dynamic knee valgus [3]. In oneleg stance, weak core and hip muscles (external rotators and abductors) can cause dynamic knee valgus, which raises the possibility of noncontact ACL rupture.…”

“…An abrupt alteration in movement results in a significant amount of valgus stress, internal rotation, and anterior tibial displacement [4]. As a result, research showed that having a stable core and hip muscles is essential for preventing ACL injuries [3]. Static and dynamic instability of the knee can result from ligament injuries.…”

Background. Lower extremity muscles weakness occur after the reconstruction of the anterior cruciate ligament (ACLR), specifically the hip muscles. The literature suggests that decreased hip strength which results from ACLR can lead to biomechanical changes in lower extremity. Objective. The aim of the current study was to assess effects of adding hip strengthening exercises with traditional strengthening exercises on early outcomes after ACLR. Materials and methods. Randomized controlled study was conducted on 50 male participants with primary unilateral ACLR, they were tested pre-operative and after 12 weeks postoperative; for pain intensity by visual analog scale (VAS), side to side difference knee extension limitation range of motion (ROM) by goniometer, and lower extremity function tests by side-to-side single-leg hop test and 10-yards test. They were assigned into two groups; group A (hip strengthening exercises with traditional strengthening exercises) and group B (traditional strengthening exercises only). Both groups received the treatment 3 sessions/week for 12 weeks. Results. The results of independent t-test showed that there were significant improvements (p < 0.05) in all variables (pain intensity, side to side difference knee extension limitation ROM, side-to-side single-leg hop test and 10-yards test) in both groups with superiority of group A. Conclusion. Adding of hip strengthening exercises to traditional strengthening exercises were effective on early outcomes post ACLR.

“…However, despite extensive research, the exact role of any of these factors in ACL injury has not been ascertained. As 70% of the ACL injuries are due to noncontact mode of injury [17], it has become important to identify various intrinsic risk factors associated with ACL injury. While previous studies have suggested that steeper posterior tibial slopes and narrow notch width are risk factors for ACL injury [3,37,41,45,55], other reports do not confirm these conclusions [1,15,21,22].…”

Background: The relationship between anterior cruciate ligament (ACL) injury and anatomical structures is still a topic of debate. Purpose: The aim of this study was to compare knee geometry in demographically matched ACL-injured and ACL-intact athletes. Methods: We conducted a case-control study comparing 2 groups, each consisting of 55 professional athletes (44 men and 11 women): 1 group with complete ACL tears (cases) and 1 group with intact ACLs (controls). The groups were compared using magnetic resonance imaging (MRI) in terms of intercondylar notch geometry, tibial plateau characteristics, and ACL volume. Results: Among cases and controls, we found the cases had lower notch width (20.24 ± 2.68 mm vs. 22.04 ± 2.56 mm, respectively) and notch width index (0.29 ± 0.03 vs. 0.31 ± 0.03, respectively). The mean ACL volume in the cases (1181.63 mm3 ± 326 mm3) was also lower than in controls (1352.61 mm3 ± 279.84 mm3). The parameters of tibial slope geometry were comparable between groups. In addition, women had lower ACL volume than men (1254 ± 310 mm3 vs. 890 ± 267 mm3, respectively) and higher medial posterior tibial slope (4.76 ± 2.6 vs. 6.63 ± 1.83, respectively). Among cases, women had narrower notch width than men (16.9 ± 2.42 mm vs. 21.08 ± 2.03 mm). However, notch width index was comparable between male (0.3 ± 0.02) and female (0.28 ± 0.03) cases. Conclusion: Our findings suggest that narrow notch width and low ACL volume may enhance the risk of ACL injury among athletes. There was no association found between posterior tibial slope and ACL injury between athletes with injured ACLs and controls. Further study is indicated.
