“…The best screening method for lower extremity injury risk in military personnel is still unknown, although there is increasing evidence in an athletic population that decreased knee flexion and increased abduction during landing from a jump may contribute to increased ACL injury risk [18]. Moreover, the factors associated with dangerous knee kinematics among the military have not been identified.…”

Musculoskeletal injuries are prevalent among active individuals, such as military personnel, which may lead to high health costs. The injuries, specifically in lower extremity joints, are mostly taking place during movements such as jumping. This study investigates the correlation between trunk muscle endurance and three-dimensional knee kinematics during jump-landing among military personnel. Materials and Methods: Thirty commandoes (Mean±SD age: 29.45±4.76) participated in the study. The researchers performed McGill standardized testing battery (core muscle endurance tests). Our subjects underwent jump-landing maneuver and 3D motion analysis of knee joint kinematics. Then the investigators analyzed the obtained data using the Pearson correlation test (P<0.05). The main outcome measures were trunk muscles' endurance and knee joint angles of flexion-extension, abduction-adduction, and internal rotation-external rotation estimated using MATLAB scripts for three trials during peak angle of knee flexion just before the rebound. We also calculated the average value for the aforementioned motions from initial contact to the takeoff phase. Results: The Pearson correlation test indicated a statistically significant correlation between the peak and average value of knee flexion angle and right (r peak =0.511, r average =0.505/ P peak =0.021, P average =0.023) and left (r peak =0.486, r average =0.445/ P peak =0.030, P average =0.049) side bridge tests. Moreover, we observed a significant negative correlation between average knee internal rotation and trunk flexors' endurance test value (r=-0.496, P=0.026). Discussion: The trunk muscles provide knee stability in dynamic tasks. Particularly, strengthening abdominal and lateral muscles of the trunk high shown to decrease knee rotation and flexion, respectively, during landing from a jump. Consequently, the authorities should emphasize this fact while designing conditioning or rehabilitation programs.

“…We learned in this CAT that movements that occur in the knee are controlled by the musculature in the hip, and therefore, alterations to knee kinetics and kinematics are the result of muscular imbalances in the hip. [2][3][4][5]12 DKV is an alteration caused by decreases in HABD, HEXT, and HER strength. 1,2,6,7,12 When overall neuromuscular control of the hip is decreased or altered, it leads to compensations that force the DKV to increase, which can make the athlete more predisposed to an injury in the entire lower extremity.…”

“…[2][3][4][5][6][7][8][9][10][11] These alterations increase abnormal stresses on the tibiofemoral joint and increase the risk of injury, such as anterior cruciate ligament injuries, patellofemoral pain, iliotibial band syndrome, acute lateral ankle sprains, chronic ankle instability, and alterations to balance. [2][3][4][5][6][7][8][9][10][11] The improper movement pattern associated with DKV is further emphasized during dynamic movements, especially in single-leg tasks when balance is incorporated into the movement, such as in single-leg landing and single-leg jumping maneuvers. 2 The most recent literature on injuries associated with DKV have focused on the clinical utility of hip strengthening.…”

“…11 DKV is a direct compensation made by individuals with weakness of hip musculature in hip abduction (HABD), hip extension (HEXT), and hip external rotation (HER). [2][3][4]12 These weaknesses lead to increased valgus at the tibiofemoral joint, and this compensation has been associated with an increased predisposition of injury. 5,11 Therefore, the purpose of this critical appraisal topic was to summarize current evidence regarding the effects of how weaknesses in HABD, HEXT, and HER are associated with an increase in the DKV angle during single-leg landing tasks.…”

Clinical Scenario: Dynamic knee valgus (DKV) is a mechanical alteration in the knee that leads to increased risk of injury. Weakness of hip musculature in hip abduction (HABD), extension (HEXT), and external rotation (HER) may contribute to increased DKV in single-leg landing tasks. Focused Clinical Question: Is decreased hip strength associated with an increase in DKV during a single-leg landing task in collegiate female athletes? Summary of Key Findings: Three studies were included: One randomized control trial (RCT), one cohort study, and one case-control. All three studies found that decreases in HABD and HER strength contributed to increased DKV during single-leg landing tasks. One study also found that the hip extensors contribute to controlling hip adduction, a common factor in many mechanisms of injuries. These three studies recommended strengthening HABD, HEXT, and HER to decrease DKV and reduce the risk of injury at the knee. Clinical Bottom Line: Weak HABD, HEXT, and HER contribute to increased DKV in college female athletes, but strengthening HABD, HEXT, and HER can lead to decreases in DKV and, overall, reduce the risk of injury at the knee. Strength of Recommendation: These articles were graded with a level of evidence of III or higher, giving a grade of B strength of recommendation that weak HABD, HEXT, and HER are associated with increased DKV in collegiate female athletes.

Background Participation of children and youth in sporting activities, among others in training and football competitions, is an optimistic manifestation of activation in the current trend of computerization. Unfortunately, this is also often associated with musculoskeletal injuries. An example is the association of dynamic valgus and disturbed dynamic balance with lower limb injuries. The main purpose of the studies is to determine the impact of three strengthening exercises on the parameters of dynamic knee valgus and balance of lower limbs. The secondary objectives are to investigate the dominant influence and the length of lower limb on the valgus values and to determine risk of injury to young football players. Methods 134 young footballers training at the Arka Gdynia SI club were invited to first stage of the research in order to examine anthropometric features and kinematics of the lower limb. Single Leg Squat Test was used, which was recorded. The samples were analyzed video to determine exact knee angle of valgus. During the second stage, to which players with valgus knee were qualified (≥15˚), the Y-Balance Test was additionally used. Intervention group underwent an exercise program to strengthen gluteus medius, popliteal and tibialis posterior muscles for 6 weeks to repeat tests in the third stage. Results Statistical methods used at the assumed level of significance allow to conclude that there are no differences in results of dynamic valgus (≥15˚) and dynamic balance between the intervention group and control group during the 6 week period between stages. In addition, there were results confirming the lack of influence of length and dominant lower limb on valgus. Results of composite direction in the Y-Balance Test test determine the low risk of injury in both intervention and control groups. Conclusions Intervention did not affect the dynamic valgus and knee balance in young football players. Both the length and the dominant limb did not affect the results. The "low risk" occurrence of injuries among the examined participants with valgus knee due to the values of dynamic balance was determined.
