Objective. To investigate the relationship between knee muscle strength and the external knee adduction moment during walking in obese knee osteoarthritis patients and whether disease severity influences this relationship. Methods. This cross-sectional study included 136 elderly obese (BMI>30) adults with predominant medial knee osteoarthritis. Muscle strength, standing radiographic severity as measured by the Kellgren and Lawrence scale, and the peak external knee adduction moment were measured at self-selected walking speed. Results. According to radiographic severity, patients were classified as “less severe” (KL 1-2, N=73) or “severe” (KL 3-4, N=63). A significant positive association was demonstrated between the peak knee adduction moment and hamstring muscle strength in the whole cohort (P=.047). However, disease severity did not influence the relationship between muscle strength and dynamic medial knee joint loading. Severe patients had higher peak knee adduction moment and more varus malalignment (P<.001). Conclusion. Higher hamstring muscle strength relates to higher estimates of dynamic knee joint loading in the medial compartment. No such relationship existed for quadriceps muscle strength. Although cross sectional, the results suggest that hamstrings function should receive increased attention in future studies and treatments that aim at halting disease progression.

Abstract Background High biomechanical loading is believed to be a risk factor to pain in people with knee osteoarthritis (OA), but controversial findings have been reported on the relationship between external knee adduction moment (KAM) and pain. A more comprehensive analysis considering other factor such as external knee flexion moment (KFM) could help better reveal this relationship. This study explored the relationship between external knee adduction moment and pain intensity in participants with knee osteoarthritis (OA) using an integrated path analysis model. Methods This was a cross-sectional study based on laboratory setting. Forty-seven participants with clinical and radiographic medial knee OA were analyzed for their external knee adduction moment (KAM) and knee flexion moment (KFM) during walking using a motion analysis system. Pain intensity was measured by visual analogue scale (VAS) and the pain subscale of the Knee Injury and Osteoarthritis Outcome Score. Varus/valgus alignment was captured and quantified using a bi-planar X-ray system. Using a path analysis model, the relationships between pain intensity, KAM, KFM, OA radiographic severity, knee varus angle and walking speed were examined. Results The proposed path model met the goodness-of-fit criteria. Based on this model, KAM had a negative effect on VAS pain indirectly through the mediation of KFM. The model indicated KAM and KFM were negatively related to one another; and KFM was positively related to VAS. The KAM index, defined as (KAM/ (KAM + KFM)), was negatively related to VAS. Conclusions Path analysis enabled the construction of a more integrated pathokinematic framework for people with knee OA. The KAM index which reflected the load sharing on the frontal and sagittal planes also revealed its relationship with pain. Re-distribution of mechanical loading from frontal to sagittal plane might be a strategy for pain avoidance associated with mechanical irritation.

The Relationship

Small knee flexion motion is a characteristic of gait in individuals with knee osteoarthritis. This study examined the relationship between knee flexion excursion in loading response and knee self-perception in individuals with knee osteoarthritis. Twenty-one individuals with knee osteoarthritis participated in this study. Knee flexion excursions in loading response while walking at a comfortable and a fast-walking speed were measured using an inertial measurement unit-based motion capture system. The degree of knee perceptual impairment was evaluated using the Fremantle Knee Awareness Questionnaire (FreKAQ). The relationships between the FreKAQ score and gait variables and knee function were evaluated by calculating the correlation coefficient. The unique contributions of knee self-perception and muscle strength to knee flexion excursion in loading response were analyzed using hierarchical linear regression. Knee self-perception was significantly correlated with pain during walking, muscle strength and knee flexion excursion at fast speed. In the fast speed condition only, impaired knee self-perception was inversely proportional to knee flexion excursion and accounted for 21.8% of the variance in knee flexion excursion. This result suggests that impaired self-perception of the knee may help to explain the decrease in the knee flexion excursion in the loading response in individuals with knee osteoarthritis.

Objectives. To investigate the relationship between external knee adduction moment (KAM) and knee osteoarthritis (OA) symptoms according to static alignment and pelvic drop. Methods. Ninety-five participants with symptomatic knee OA were included. Radiographic severity was graded by Kellgren and Lawrence (KL) scale. The hip-knee-ankle (HKA) angle was used to assess limb alignment from a full-length lower-limb radiograph. KAM-related variables (peak KAM and KAM impulse) and pelvic drop angle were determined from 3D gait analysis. Symptoms were assessed via visual analog scale (VAS) for pain and hospital for special surgery (HSS) score for physical function. The relationship between KAM and symptoms was evaluated according to radiographic severity and pelvic drop using linear models. Results. According to the more affected knee in the varus group, both the two KAM-related measures (peak KAM and KAM impulse) were positively associated with greater VAS pain and were negatively associated with HSS score. Only peak KAM was correlated with VAS and HSS in the valgus group. VAS pain score of the more affected knee was positively correlated with pelvic drop angle. Stratified by pelvic drop angle, KAM-related variables were more positively associated with VAS pain and negatively associated with HSS score for patients with pelvic drop angle ≤3 degrees. The relationships between KAM and symptoms according to radiographic disease severity remained confusing. Conclusions. Static alignment and pelvic drop angle significantly affected relationships between KAM-related variables and knee OA symptoms, which may explain the confusing results as shown by previous studies.

ObjectivesTo evaluate the relationship between mechanical loading, as indicated by the external knee adduction moment (KAM) during walking, and BML on MRI in people with medial knee osteoarthritis.MethodsMeasures were taken in 91 individuals with medial knee osteoarthritis. Logistic regression analyses were performed with the presence/absence of medial tibial or medial femoral BML as the outcome and either peak KAM or KAM impulse as the independent variable. Analyses were also adjusted for age, gender, body mass index, alignment and walking speed.ResultsIn adjusted analyses, peak KAM was significantly related to medial tibial (OR 2.3; 95%CI 1.07 to 4.7), but not medial femoral (OR 1.85; 95%CI 0.93 to 3.7) BML. KAM impulse was significantly related to both medial tibial (OR 9.4; 95%CI 1.53 to 57.2) and medial femoral (OR 14.4; 95%CI 2.3 to 89.8) BML.ConclusionsThe findings support the hypothesis that greater mechanical loading of the medial compartment plays a role in the pathogenesis of BML in medial tibiofemoral osteoarthritis.

Background: The higher body mass index is a risk factor that associated with onset and progression of knee osteoarthritis by increasing the knee adduction moment. Lateral wedge insoles are used for reducing the knee adduction moment which may prevent the occurrence of knee osteoarthritis in healthy population.Purpose: The purpose of this study was to assess the effectiveness of the lateral wedge insole among normal, overweight, obese I and obese II female while walking.Methods: A cross-sectional experimental design study was used to investigate 80 females who aged between 18 – 40 years using 3-D Motion Analysis. The peak external knee adduction moment was collected in walking shoes and walking shoes with 5-degree lateral wedge insoles conditions. The significant difference was determined using Paired-T test (p = 0.05).Results: The peak external knee adduction moment was significantly decreased by the effect of shoes with lateral wedge insoles in normal, overweight and obese I (22.12%, 18.34% and 24.15%). However, it did not change in the obese II.Conclusion: The peak external knee adduction moment was decreased by the immediate effect of lateral wedge insoles. It may prevent the onset of knee osteoarthritis in normal, overweight, and obese I. Further study should investigate long term effect of lateral wedge insoles on the knee joint load and the effect of dose in higher body mass index.
