What percentage of old people have hip replacements? Age-based statistics

According to a 2015 study, the prevalence of total hip replacement in the U.S. population increased with age, reaching 5.26% among people 80 years old and 5.87% among those 90 years old in 2010. This reflects the increasing likelihood of older adults needing the surgery due to age-related conditions like advanced osteoarthritis.
