Driving after hip and knee replacement — when is it safe?

Returning to driving is one of the milestones patients look forward to most after joint replacement, because it marks a return to independence. The timing is not fixed by a calendar — it depends on which side was operated on, the type of vehicle, and most importantly whether you can control the car safely in an emergency.

The safety test that matters

The key question is not how many weeks have passed, but whether you could perform an emergency stop without hesitation or pain. You must have enough strength, range of movement and reaction speed in the operated limb to brake hard and quickly. Until that is true, driving is not safe — for you or others on the road.

Left versus right

In an automatic vehicle, the left leg is not used for driving. So for surgery on the left hip or knee in an automatic car, return to driving can be relatively early — sometimes within a couple of weeks — provided you are off strong pain medication and comfortable getting in and out.

Surgery on the right leg, or driving a manual car after either leg, requires more recovery because the operated limb controls the brake or clutch. For these patients, returning to driving is commonly discussed at around four weeks after a hip replacement and four to six weeks after a knee replacement, but these are guides rather than rules. The criteria matter more than the calendar.

Pain medication

You must not drive while taking opioid pain medication or anything else that causes drowsiness or slows reaction time. Dr Mooney’s guidance is that you should not drive within eight hours of taking an opioid pain medicine. Being clear of these medications is a non-negotiable prerequisite, regardless of which leg was operated on.

Insurance and the law

There is no single legislated waiting period, but you have a responsibility to be in control of the vehicle. If you drive before you are safely able to, your insurer may decline a claim in the event of an accident. It is sensible to confirm you are ready with your surgeon, and some patients choose to check with their insurer.

Easing back in

When you do return, start with short, familiar trips in quiet conditions before longer or busier drives. Make sure you can comfortably get in and out of the car, reach the pedals, and turn to check blind spots. If anything causes pain or hesitation, it is too soon.

Your surgeon will give you advice tailored to your operation and progress at your follow-up review. Always confirm before getting back behind the wheel.
