Most people can start driving again about 4 weeks after knee replacement surgery. The exact timing depends on factors such as which knee was replaced, whether the car is automatic or manual, medications taken, pain levels, and individual recovery progress. Specifically:

• If the left knee was replaced and the car is automatic, driving may be possible as early as 2 weeks after surgery since the left leg does not operate the pedals.
• If the right knee was replaced, patients usually need to wait 3 to 4 weeks because the right leg controls the pedals.
• Manual transmission vehicles generally require a longer wait, often 3 to 4 weeks or more, due to more leg movement required.
• Partial knee replacement patients might return to driving sooner than total knee replacement patients.
• Patients should not drive while on strong pain medication.
• It is crucial to feel safe getting in and out of the car and to be able to perform an emergency stop during a test without pain before driving on roads.
• A gradual return to driving is recommended, starting with short drives to build confidence.

Medical clearance, checking with your surgeon or physiotherapist, and insurance advice are important parts of the decision to resume driving.
