Anterior Cruciate

  The Anterior cruciate ligament (ACL) plays an important role in maintaining knee-joint stability. Most ACL injures (approximately 65%) are due to a non-contact mechanism during physical activities, particularly in sports involving a landing from a jump, pivoting on the leg, rapid deceleration and cutting maneuvers. The average injury of ACL rates is still high for both professional and recreational athletes in particular between the group ages of 15 to 25 year old. The purpose of this article was to review and analysis the causes and potential risk factors for the ACL injury. Several anatomic and neuromuscular risk factors are associated with increased risk of suffering ACL injury, such as shoe-surface interaction, quadriceps angle, knee-joint laxity, genu varum of knee, and body composition. These risk factors most likely act in combination to influence the risk of ACL injury. Therefore, these factors should be considered when designing training programs, competitions, and implementing ACL injury prevention programs.

Restricted hip movement along with femoroacetabular impingement (FAI) has been reported to be an important risk factor in anterior cruciate ligament (ACL) injury. We performed a literature review assessing the evidence that FAI, or restricted hip movement, contributes to the likelihood of sustaining an ACL injury to provide an evidence-based and comprehensive update on the relationship between these pathologies. Studies were divided into three categories: clinical studies, radiological studies and cadaveric studies. Clinical studies primarily assessed the limitations to hip movement in patients with ACL injury, and numerous studies of this kind have demonstrated a relationship between restricted movement and ACL injury. Radiological studies have been able to demonstrate a higher number of bony hip abnormalities in patients with ACL injury. However, due to variable results within these studies, it is unclear which kinds of bony abnormality are specifically associated with an increased risk of ACL injury. Cadaveric studies have demonstrated that peak ACL relative strain was inversely related to the range of internal rotation of the femur, thus providing a potential mechanism for this relationship. In conclusion, clinical and radiological studies have established a correlation between restricted hip and ACL injury, but have been unable to demonstrate an increased risk of future ACL injury in individuals with restricted hip movement. Future prospective cohort studies are necessary to confirm this. Additionally, these findings highlight the need for a thorough clinical assessment of the hip when assessing patients with an ACL injury.

Non-contact anterior cruciate ligament (ACL) injury can occur in many sports. It is interrelated with gender, anatomy, biomechanics, and neuromuscular control. Taekwondo athletes have a higher incidence of ACL injury than athletes from other sports. Objective: This study aimed to determine the biomechanical gender differences and mechanism of taekwondo athletes with ACL injury. Methods: A total of 28 taekwondo athletes (aged 14–19 years) were randomly selected and grouped by gender. Feet high floor, one foot high floor, and single leg squat were analyzed by a Vicon motion analysis system and Kistler 3D force platform for action. The knee joint angle and ground force were evaluated. Results: Results demonstrated biomechanical differences in knee joint between male and female athletes. Conclusion: ACL injury in taekwondo female athletes indicated the biomechanical mechanism of the knee joint, and it can be prevented by neuromuscular control training.

The geometry of the tibial plateau and the femoral condyles are emerging as key parameters to be studied as anterior cruciate ligament (ACL) injury risk factors. In this paper, we study the role of curved profile of the medial compartment of the tibia in a sagittal plane as a critical risk factor for the anterior cruciate ligament (ACL) injuries. The curvature of the mid-medial compartment of Tibia in 40 uninjured controls (21 women and 19 men) and 44 anterior cruciate ligament-injured cases (23 women and 21 men) were measured using magnetic resonance images and in-house matlab programming. We hypothesized that the Individuals with a less curved profile in the medial compartment of the tibia are at increased risk of suffering an anterior cruciate ligament injury compared to those with larger curved profiles. Based on t-tests, we established that the uninjured controls had larger curvature (p<0.05) compared to the injured cases. Biomechanically speaking a larger curvature of the tibia could prevent excessive sliding movement of femur with respect to the tibia, and thus could reduce the ACL strain. We suggest that future studies are needed to confirm this relationship and to evaluate the potential role of this curved profile of tibia in the risk of ACL injury.

Background: The incidence of contralateral anterior cruciate ligament (CACL) injuries after recovery from a first-time anterior cruciate ligament (ACL) disruption is high in women; however, little is known about the risk factors associated with this trauma. Hypothesis: Patient characteristics, strength, anatomic alignment, and neuromuscular characteristics of the contralateral uninjured leg at the time of the first ACL trauma are associated with risk of subsequent CACL injury, and these risk factors are distinct from those for a first-time ACL injury. Study Design: Case-control study; Level of evidence, 3. Methods: Sixty-one women who suffered a first-time noncontact ACL injury while participating in high school or college sports and underwent measurement of potential risk factors on their contralateral limb soon after the initial ACL injury and before reconstruction were followed until either a CACL injury or an ACL graft injury occurred, or until the last date of contact. Results: Follow-up information was available for 55 (90.0%) of the 61 athletes and 11 (20.0%) suffered a CACL injury. Younger age, decreased participation in sport before the first ACL disruption, decreased anterior stiffness of the contralateral knee, and increased hip anteversion were associated with increases in the risk of suffering a CACL injury. Conclusion: A portion of CACL injury risk factors were modifiable (time spent participating in sport and increasing anterior knee stiffness with bracing), while others were nonmodifiable (younger age and increased hip anteversion). The relationship between younger age at the time of an initial ACL injury and increased risk of subsequent CACL trauma may be explained by younger athletes having more years available to be exposed to at-risk activities compared with older athletes. A decrease of anterior stiffness of the knee is linked to decreased material properties and width of the ACL, and this may explain why some women are predisposed to bilateral ACL trauma while others only suffer the index injury. The risk factors for CACL injury are unique to women who suffer bilateral ACL trauma compared with those who suffer unilateral ACL trauma. This information is important for the identification of athletes who may benefit from risk reduction interventions.

Introduction: Nowadays, the use of artificial turf fields has become widespread. Given the high prevalence of noncontact injuries among female soccer players and high contribution of the Anterior Cruciate Ligament (ACL) injury, this research was conducted to compare biomechanical risk factors in the incidence of ACL injury for elite female soccer players during shearing maneuver and header on the natural grass and artificial turf fields. Methods: Sixteen players were selected from U-14 women’s national team by the convenience sampling method and started to perform the skills. Knee joint information was calculated by a 3D imaging system and a force plate. Statistical differences were reported using the dependent t-test at a significant level of 0.05. Results: The findings showed that the biomechanical behavior of the lower extremity while performing soccer skills on the natural grass was affected differently from that on the artificial turf. Results also demonstrated that the torque applied to the knee joint on the natural grass was higher than that on the artificial turf (P=0.039). Angular velocity on the artificial turf was also higher than that on the natural grass (P=0.006). Conclusion: The higher knee joint torque and the lower angular velocity on natural grass may result in a higher risk of ACL injury on the natural grass than on the artificial turf. Therefore, the use of prevention programs for ACL injury is crucial to minimize the incidence of lower extremity injuries.

ABSTRACT Introduction: ACL injury of the knee joint is common in sports. Due to the special characteristics of strong physical confrontation and high speed, basketball has a high risk of ACL injury. Objective: To investigate the stability of anterior cruciate ligament (ACL) reconstruction on knee injury in athletes. Methods: In the south, medical research selected 3 cases of unilateral injuries in men's basketball athletes with arthroscopic anterior cruciate ligament autogenous tendon revascularization. We started collecting and recording data of three players three days after rehabilitation training, at various stages in the process Results: At the end of rehabilitation training, 10 weeks after operation, the pain disappeared, the range of motion of the knee joint increased significantly, muscle atrophy of bilateral lower limbs diminished, knee joint stability improved, knee joint muscle strength of the affected leg strengthened, and the rehabilitation goal was basically accomplished. Conclusions: Early rehabilitation training can effectively restore the movement function of the patient's knee joint, improve the efficiency of rehabilitation and shorten the rehabilitation period, thus helping the injured individual recover from the injury and return to the game rapidly. Level of evidence II; Therapeutic studies - investigation of treatment results.

Anterior Cruciate

High incidences of non-contact anterior cruciate ligament (ACL) injury, frequent requirements for ACL reconstruction, and limited understanding of ACL mechanics have engendered considerable interest in quantifying the ACL loading mechanisms. Although some progress has been made to better understand non-contact ACL injuries, information on how and why non-contact ACL injuries occur is still largely unavailable. In other words, research is yet to yield consensus on injury mechanisms and risk factors. Biomechanics, video analysis, and related study approaches have elucidated to some extent how ACL injuries occur. However, these approaches are limited because they provide estimates, rather than precise measurements of knee - and more specifically ACL - kinematics at the time of injury. These study approaches are also limited in their inability to simultaneously capture many of the contributing factors to injury. This paper aims at elucidating and summarizing the key challenges that confound our understanding in predicting the mechanisms and subsequently identifying risk factors of non-contact ACL injury. This work also appraise the methodological rigor of existing study approaches, review testing protocols employed in published studies, as well as presents a possible coupled approach to better understand injury mechanisms and risk factors of non-contact ACL injury. Three comprehensive electronic databases and hand search of journal papers, covering numerous full text published English articles were utilized to find studies on the association between ACL and injury mechanisms, ACL and risk factors, as well as, ACL and investigative approaches. This review unveils that new research modalities and/or coupled research methods are required to better understand how and why the ACL gets injured. Only by achieving a better understanding of ACL loading mechanisms and the associated contributing factors, one will be able to develop robust prevention strategies and exercise regimens to mitigate non-contact ACL injuries.

The geometry of the tibial plateau as well as the femoral condyles are emerging as key parameters to be studied as anterior cruciate ligament (ACL) injury risk factors. In this paper, we study the role of tibial eminence size as a potentially important characteristic of the tibial plateau in loading and or protecting the ACL from injury. The volume of Tibial eminence in 52 uninjured controls (32 women and 20 men) and 44 anterior cruciate ligament-injured cases (23 women and 21 men) were measured using magnetic resonance images and 3-d image reconstruction using commercial software Analyze 9.0. We hypothesized that the Individuals with a small tibial eminence are at increased risk of suffering an anterior cruciate ligament injury compared with those with larger tibial eminences. Based on t-tests, we established that the uninjured controls had larger tibial eminences (p<0.05) compared with the injured cases. Biomechanically speaking a larger tibial eminence could prevent excessive medio-lateral movement of femur with respect to the tibia. A larger eminence could also protect the knee from large magnitude rotational movements. We suggest that future studies are needed to confirm this relationship and to evaluate the potential role of the tibial eminence size in the risk of ACL injury.

The Relationship

Anterior cruciate ligament (ACL) tears are a common injury, particularly in the athletic and youth populations. The known association between ACL injury and subsequent osteoarthritis (OA) of the knee merits a more in-depth understanding of the relationship between the ACL-injured knee and osteoarthritis. ACL injury, especially with concomitant meniscal or other ligamentous pathology, predisposes the knee to an increased risk of osteoarthritis. ACL insufficiency results in deterioration of the normal physiologic knee bending culminating in increased anterior tibial translation and increased internal tibial rotation. This leads to increased mean contact stresses in the posterior medial and lateral compartments under anterior and rotational loading. However, surgical reconstruction of the ACL has not been shown to reduce the risk of future OA development back to baseline and has variability based on operative factors of graft choice, timing of surgery, presence of meniscal and chondral abnormalities, and surgical technique. Known strategies to prevent OA development are applicable to patients with ACL deficiency or after ACL reconstruction and include weight management, avoidance of excessive musculoskeletal loading, and strength training. Reconstruction of the ACL does not necessarily prevent osteoarthritis in many of these patients and may depend on several external variables.
