“…Using one hand, the examiner palpated the greater trochanter until it was positioned laterally and maximally during passive internal rotation of the hip joint. The examiner then used a handheld goniometer with his other hand to measure the angle between the tibial lines, a line bisecting the medial and lateral malleoli, and an imaginary vertical line extending from the table 13 , 14 ) .…”

[Purpose] The purpose of this study was to determine the inter- and intra-examiner reliability of measurement methods for femoral anterversion during Craig’s test. [Subjects and Methods] The study included 37 healthy participants (20 males and 17 females). Two novice examiners (Department of Physical Therapy students at Silla University) used three different methods to measure the femoral anterversion during Craig’s test: a goniometer, a goniometer with a laser beam, and an inclinometer. [Results] The intra-examiner reliability was high for both examiners with all three measurement methods, with scores of 0.82, 0.86, and 0.73 for examiner 1 and 0.74, 0.78, and 0.72 for examiner 2 for the goniometer, goniometer with the laser beam, and inclinometer, respectively. The inter-examiner reliability during Craig’s test was below moderate for both the goniometer (0.25) and inclinometer (0.27) and moderate for the goniometer with the laser beam (0.62). [Conclusion] This study found that Craig’s test using a goniometer with a laser beam had high intra-examiner reliability and moderate inter-examiner reliability. Clinically, these findings may supplement existing measurement skills and reduce the difficulty of locating the goniometer axis during Craig’s test.

“…Previous authors have proposed an association between increased femoral antetorsion and a higher risk of noncontact ACL injuries, 2,3,19 possibly explained through an increase in the Q angle. Shultz et al suggested that greater hip antetorsion and associated intoeing could lead to excessive internal rotation of the tibia and greater rotatory stress on the knee.…”

“…12 In a more recent study, Kaneko and Sakuraba showed that increased femoral antetorsion leads to anterior tibial displacement upon single-leg landing through a combination of lower hip flexion angle, higher knee valgus alignment, and greater rectus femoris muscle activity. 3 In a cadaveric experiment designed to study the effect of femoral torsion on knee kinematics during flexion, Sobczak et al showed that medial femoral torsion decreased medial tibiofemoral translation, whereas lateral femoral torsion increased medial translation. 13 In this study, we aimed to investigate how increased or decreased femoral antetorsion would affect the biomechanics of the knee in an ACL-deficient cadaveric model.…”

Effect of Femoral Antetorsion on Tibiofemoral Translation and Rotation in the Anterior Cruciate Ligament Deficient Knee

We aimed to investigate how increased or decreased femoral antetorsion would affect the biomechanics of the knee in an anterior cruciate ligament (ACL)-deficient cadaveric model. We hypothesized that external or internal rotation of the distal femur, achieved through a femoral osteotomy, would affect the magnitude of tibiofemoral translation and rotation. Navigated measurements of tibiofemoral translation and rotation during the anterior drawer, Lachman, and pivot shift tests were performed on six whole-body cadaveric specimens in each of the following four conditions: native, ACL-deficient knee, ACL-deficient knee and 20-degree internal distal femur rotation, and ACL-deficient knee and 20-degree external distal femur rotation. Increased femoral antetorsion significantly reduced anterior tibial translation in the ACL-deficient knee during the anterior drawer, Lachman, and pivot shift tests (p < 0.05). Conversely, decreasing femoral antetorsion resulted in an increase in anterior tibial translation in the anterior drawer (nonsignificant), Lachman (p < 0.05), and pivot shift (p < 0.05) tests. Internally rotating the distal femur significantly reduced the magnitude of tibial rotation during the pivot shift test in the ACL-deficient knee (p < 0.05), whereas external rotation of the distal femur significantly increased tibial rotation (p < 0.05). The magnitude of femoral antetorsion affects tibiofemoral translation in an ACL-deficient cadaveric mode. Internally rotating the distal femur 20 degrees reduced the magnitude of tibial translation and rotation similar to that of the native knee, whereas externally rotating the distal femur aggravated translational and rotational instability.

Purpose: Changes in lower extremity alignment in individuals with abnormality of this segments are unclear. The present study aimed to compare lower extremity alignment in subjects with genu valgum and genu varum deformities and healthy subjects in order to understand the lower extremity alignment changes in this group. Methods: This was a causal-comparative study. The sample comprised 120 males selected by convenience sampling method. In total, 40 subjects were assigned to genu valgum group, 40 to genu varum group, and 40 to healthy subject group. Lower extremity alignment was evaluated in anteversion of hip, Q angle, internal and external rotation of hip, knee hyperextension, tibial torsion, tibia vara, and foot arch index, at the laboratory of Tehran University, Tehran, Iran. To compare the mean score of variables between the groups, 1-way Analysis of Variance (ANOVA) was used. The obtained data were analyzed by SPSS. Results: The internal rotation of hip, Q angle, anteversion of hip, knee hyperextension and plantar arch index were significantly higher in the subjects with genu valgum deformity, compared to the subjects with genu varum deformity. The tibia vara value was significantly higher in the subjects with genu varum deformity than those with genu valgum deformity. However, no significant differences was found between the tibial torsion and external rotation of hip in the study groups. Conclusion: The lower extremity alignment changes in the subjects with genu valgum deformity included increased anteversion, Q angle, flatfoot, knee hyperextension, and internal rotation of the hip. Also, the changes in the subjects with genu varum deformity included decreased Q angle, internal rotation of hip, knee hyperextension, but increased tibia vara, and foot arch.
