However, little is known about whether the functions of the hip abductor and rear-foot increase dynamic knee valgus. A two-dimensional（2D） video-based screening test focused on hip abductor and rear-foot functions among factors involved in dynamic knee valgus. The present study determined associations between hip and rear-foot dynamic alignment and dynamic knee valgus.Methods： This cross-sectional study recruited 130 female basketball players（258 legs） from nine high-school teams. The players performed single-leg squats and single-leg drop landings to provide knee-in（KID） and hip-out（HOD） distances on 2D video images. Hip and rear-foot dynamic alignment was evaluated using a dynamic Trendelenburg test（DTT） and a dynamic heel-floor test（HFT）.Results： The Chi-square test revealed no significant difference in the prevalence of DTT-positivity between single-leg squats（28.7%） and singleleg drop landings（23.3%）. The prevalence of HFT-positivity was significantly greater during landings（51.4%） than during single-leg squats（31.0%, p 〈 0.01）. The KID values for both single-leg squats and single-leg drop landings were greater in the DTT-positive than in the DTTnegative group（15.1 5.4 cm and 20.2 7.5 cm, p 〈 0.001）. The HOD values were similarly greater in the DTT-positive group（15.2 1.9 cm and 17.6 2.8 cm, p 〈 0.001）. The KID values for both single-leg squats and single-leg drop landings were greater in the HFT-positive than in the HFT-negative group（12.2 5.1 cm, p 〈 0.01; 14.7 7.2 cm, p 〈 0.001）, whereas HOD values for these tasks did not significantly differ between the two groups.Conclusion： Dynamic hip mal-alignment might be associated with both greater KID and HOD, whereas rear-foot eversion is associated only with greater KID. Hip abductor and rear-foot dysfunction are important factors for dynamic knee valgus and thus evaluating DTT and HFT will help to prevent dynamic knee valgus.展开更多

Setting: Orthopedic Hospital Setting on the East Coast of the United States. Study Design: Cross-sectional retrospective chart review. Methods: The desired demographic, physical and psychological attributes of 1040 adults with end-stage hip osteoarthritis hospitalized for hip surgery were recorded and subjected to comparison and correlational analyses. These data included gender, self-reported weight, height, numbers and nature of physical and psychological comorbidities, pain intensity, ambulatory capacity and discharge destination. Sub-group analyses of 808 candidates hospitalized for primary unilateral surgery were also conducted using SPSS 16. Results: There were significant (p 【0.05) associations between gender, pain scores, comorbidity numbers and ambulatory capacity. Specifically, women who exhibited higher comorbid disease rates than men, exhibited higher pre-surgery pain levels and greater functional limitations in walking ability before and after surgery than men with the same condition. In sub-group analyses of men and women with the same mean age, comorbid prevalence rates, and body mass indices, women were found to have significantly higher ideal weights on average than men, and those with higher ideal weights recovered more slowly after surgery (p 【0.05). Conclusion: The presentation of hip joint osteoarthritis is not uniform, and may be impacted differentially by gender. Women with high ideal body weights, may be specifically impacted. Whether genetic or other factors account for gender differences in pain and function among adults with disabling hip osteoarthritis observation needs to be examined.展开更多
