Abstract
Objective: To examine gender differences in self-reported pain and function before and after hip replacement surgery and the extent to which overweight, comorbidities and muscular status impact pain and function in adults with disabling end-stage hip joint osteoarthritis. 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.
Highlights
Hip joint osteoarthritis, a prevalent medical condition, causes considerable distress and chronic disability among community-dwelling adults aged 55 years and older in all countries
A debilitating condition that increases in prevalence with age, presents an enormous challenge to the health care system worldwide due to its chronicity
The goal was to identify new perspectives or to further support current perspectives about what may be most appropriate for purposes of reducing the disability and handicap of hip joint osteoarthritis
Summary
A prevalent medical condition, causes considerable distress and chronic disability among community-dwelling adults aged 55 years and older in all countries. Associated with substantial direct as well as indirect costs, a number of factors other than aging may influence its impact These factors include the presence of one or more comorbid health conditions [1] varying degrees of pain [2], variations in the disease itself [3], gender [4], high body weights [5], as well as proprioceptive, muscle strength and hip flexion range of motion deficits. It was felt that if further evidence for important subsets in the expression of the disease could be identified, more targeted efforts to reduce the significant social and economic burden of the disease might be forthcoming in the future Factors such as prevailing mental and physical impairments, other than hip osteoarthritis and their interaction with pain and functional capacity have received limited attention in the related literature [3]
