Interferes with ADL more than the patient is willing to accept
ADL means Activities of Daily Living: the everyday activities that matter to a patient's independence, comfort, and quality of life.
Examples of affected activities
- Walking
- Working
- Leisure activities
- Sleeping
When symptoms become unacceptable
Many people can accept some level of aches and pains. Total knee replacement is not indicated in such individuals.
If, on the other hand, the pain significantly interferes with day-to-day activities (such as walking, working, leisure activities, sleeping etc.) beyond what the affected person can tolerate, then total knee replacement, if successful, may allow the patient to return to such activities.
