Physical therapy & exercise
Stronger muscles. A joint with more support.
Who might it suit?
For: Knee or hip arthritis, at any stage you can participate.
Not for: A compulsory delay once replacement is indicated.
Limits and important cautions
PT treats symptoms and function; it does not replace worn cartilage. A knee trial should not be read as proof that every PT program is equivalent.
What happens, how long, and what could it cost?
- What happens
- Assessment of movement and goals, followed by a tailored exercise plan and instruction.
- When might I notice a change?
- Progress is assessed over repeated practice, not a single session.
- How long might benefit last?
- An ongoing movement plan is usually part of maintaining function.
- Repeat treatment
- Review progress and adjust exercises rather than repeat an unchanged plan indefinitely.
- Activity and recovery
- The exercise dose and any activity modifications should fit your symptoms and ability.
- Ask for a complete estimate
- Assessment, number of sessions, home program, and any equipment.
