A new US Study shows that total knee replacement is cost-effective for patients with severe arthritis.  Review the research results in this article from Health Day.

The results showed that, overall, total knee replacement (arthroplasty) increased quality-adjusted life expectancy among Medicare patients (average age 74) from 6.822 to 7.957 years. The total cost for people receiving total knee replacement was $57,900, compared with $37,100 for those who didn’t undergo knee replacement. That means the cost-effectiveness ratio of total knee replacement was $18,300 per quality-adjusted life year.
