Rearfoot Eversion

Abnormal motion of the foot has been suggested to be a potential contributor to the medial collapse of the knee seen in individuals with patellofemoral pain syndrome during a one-leg squat. Rearfoot frontal plane range of motion and peak angle were investigated during a one-leg squat in patients with patellofemoral pain syndrome compared with controls. A significant increase in the peak eversion angle was found for the patellofemoral pain syndrome group compared with controls (P = .02). Increased rearfoot eversion may contribute to the knee medial collapse observed in these patients because it may lead to tibial abduction relative to the femur. Nevertheless, further research is required to investigate the causal relationship because it remains unclear whether rearfoot eversion instigates the medial collapse of the knee.

Position Shift

Patellofemoral Pain Syndrome (PFPS) is pain in the front knee joint due to muscle imbalance especially weakness of the vastus medialis oblique muscle and the stiffness of the hamstrings leads to a patellar position shift to the lateral side (maltracking). Selective VMO exercise is one of conservative therapy to restore VMO muscle strength. The purpose of this study was to determine the effect of Selective Vastus Medial Obliquus Exercise on decreasing the degree of pain and attainment of  Range Of Motion patients with PateloFemoral Pain Syndrome. The method of this research used pre experimental design with one group pre-post test design without group control. The number of samples is 13 respondents PFPS who meet the criteria of inclusion and exclusion with purposive sampling. Data were obtained from observation of difference of Visual Analogue Scale (VAS) and ROM (universal goniometer) pain score before (pre-test) and after (post-test) doing exercise therapy. All data were analyzed statistic using Wilcoxon Signed Ranks Test with significance value (p <0,05).. The result of this research shows that there is selective effect of Vastus Medial Obliquus Exercise on the decrease of pain degree with p value = 0.001 (α = 0,05) and attainment of Range Of Motion patient with flexy value p value = 0,039 (α = 0,05) p value = 0.001 (α = 0.05). Decreasing the degree of pain post selective VMO exercise and attainment full ROM showed strengthening of VMO muscle so patella returned to optimal tracking. Suggestion: Measurement of VMO and VL muscle strength can be done with EMG.

The Relationship

The reference posture used in angular motion calculations may play an important role in the relationship found between static posture and rearfoot motion in the frontal plane in a clinical population such as patients with patellofemoral pain syndrome. This study examined the relationship between rearfoot inversion and eversion during the stance phase of walking and the static relaxed standing measurement in women (aged 18 years and older) with patellofemoral pain syndrome and controls and examined the influence of the reference posture used when calculating dynamic motion. Two reference postures were investigated: vertical alignment between the rearfoot and the lower leg and relaxed calcaneal standing. When using the latter reference posture, a significant correlation was found between the static relaxed standing measurement and peak eversion in controls only. When using the vertical alignment reference posture, significant correlation was found only in the patellofemoral pain syndrome group for peak eversion and inversion. The positive relationship found in the patellofemoral pain syndrome group between dynamic angular measures, based on a neutral reference posture, and static relaxed standing indicated that for subjects with patellofemoral pain syndrome, the clinical rearfoot measurement of relaxed standing can be used to explain the pattern of rearfoot motion during walking.

We examined the effects of medially wedged foot orthoses on knee and hip joint mechanics during running in females with and without patellofemoral pain syndrome (PFPS). We also tested if these effects depend on standing calcaneal eversion angle. Twenty female runners with and without PFPS participated. Knee and hip joint transverse and frontal plane peak angle, excursion, and peak internal knee and hip abduction moment were calculated while running with and without a 6° full-length medially wedged foot orthoses. Separate 3-factor mixed ANOVAs (group [PFPS, control] x condition [medial wedge, no medial wedge] x standing calcaneal angle [everted, neutral, inverted]) were used to test the effect of medially wedged orthoses on each dependent variable. Knee abduction moment increased 3% (P= .03) and hip adduction excursion decreased 0.6° (P< .01) using medially wedged foot orthoses. No significant group x condition or calcaneal angle x condition effects were observed. The addition of medially wedged foot orthoses to standardized running shoes had minimal effect on knee and hip joint mechanics during running thought to be associated with the etiology or exacerbation of PFPS symptoms. These effects did not appear to depend on injury status or standing calcaneal posture.

ABSTRACT Objective: To define a profile of the muscle groups affected by patellofemoral pain syndrome (PFPS) to determine a pattern of functional weaknesses around the knee. Methods: Sixty-three female patients were randomly selected, and 17 included in this study, receiving a clinical evaluation with pre-established protocol which evaluated the quadriceps, abductors, range of motion in the internal rotators and ankle dorsiflexors, pelvic tilt, and dynamic valgus. Results: Losses were seen in abductor strength and ankle dorsiflexor range of motion in comparison with the contralateral limb (0.031 and 0.040, respectively). There was a loss of quadriceps strength and decreased amplitude of internal hip rotation when compared to the Kujala score (0.032 and 0.002, respectively). Dynamic valgus and pelvic fall were greater in comparison with the Kujala score (0.668 and 0.567, respectively). Conclusion: Clinical evaluation showed deficits in the quadriceps and abductor muscle groups, as well as decreased range of motion in the internal hip rotators and ankle dorsiflexors and increased dynamic valgus and pelvic drop. Level of Evidence IV; Case series.
