Knee injury limiting what you can do at work? A GP can assess your capacity and, if clinically appropriate, issue a medical certificate for knee injury, including restrictions.

Weight Bearing Capacity and What It Means for Your Role
How much weight you can put through the knee shapes what work you can do. A fitness for work certificate can record what you can manage, not just that you need time off.
Restrictions are clearest when they name the task. "No kneeling", "limit standing to short periods" or "no ladders" tells a supervisor exactly what to change. A general "light duties" note leaves too much to guesswork.
- How the injury happened
- Swelling, locking or giving way
- How long you can stand or walk
- Whether your job involves kneeling or ladders
How a Knee Consult Runs
Your consult starts by phone, and the GP may switch to video to see how you move. A consult for someone under 18 is by phone or video, as the GP decides, with a parent or guardian present.
Common Knee Injuries
Healthdirect's knee injuries page lists common injuries, including torn ligaments, a torn meniscus and damage to the cartilage lining the knee. Each can affect weight-bearing differently, which is why the GP asks what happened and what you can do now.
When an In-Person Exam or Imaging Comes First
Healthdirect says that describing what happened and doing a physical examination can be enough to diagnose a knee injury. A doctor may also order an X-ray, CT or MRI scan.
Describing Your Knee Before the Consult
Start with how it happened. Healthdirect says knee injuries are particularly common when you twist your knee while bearing weight.
A Twist or a Slow Ache
A planted foot and a turning body tell a GP something different from an ache that crept up over months.
What You've Noticed
Next, list what you've noticed. Healthdirect's knee pain page names swelling, bruising, giving way, locking, clicking and trouble straightening the leg.
Front or Back of the Knee
It says pain at the front of the knee can mean bursitis or arthritis, and pain at the back can mean arthritis or cysts.
Not a Self-Diagnosis
You can't diagnose yourself from that list, but the details help the GP decide what to ask next.
When Swelling, Heat or Colour Changes Mean Go Back for Care
A phone consult can't check these signs by touch. If they appear, an in-person exam comes first, and the certificate waits.
Go to an Emergency Department
Healthdirect advises going to an emergency department if your knee is badly swollen or has changed shape. The same applies if you have a fever with a red, hot knee, or the pain follows a major injury.
See a Doctor
See a doctor if you can't put weight on it, can't move it, or it locks or gives way.
Signs to Get Help
The NSW Emergency Care Institute's knee fact sheet lists signs that mean you should see your doctor. They include worsening pain, being unable to bear weight, increasing swelling, changes in sensation or colour, and a hot, red knee or fever. If you can't see a doctor, it says to return to the emergency department. Queensland Health lists constant tingling and numbness, or colour change in the leg, as signs to get help.

Wear and Tear Versus a Sudden Injury
Not every sore knee comes from one bad moment. Healthdirect's osteoarthritis page names knees among the joints most often affected. It lists physically demanding jobs, such as heavy lifting or manual labour, as risk factors.
It suggests talking to your doctor or physiotherapist about adjusting your usual activities so they don't worsen the condition.
A Different Plan
That matters for restrictions. A sudden twist may call for a short, defined period of limits, while a long-standing joint problem may need a different plan. Your regular GP is better placed to build that kind of plan, because they hold your history.
How Long a Knee Injury Takes
Nobody can promise a date. Australian health services give ranges.
| Source | What it says | Applies to |
|---|---|---|
| NSW Emergency Care Institute | Three to six weeks to heal properly | Minor knee soft tissue injuries |
| Queensland Health physiotherapy handout | A typical window of 1 to 8 weeks, varying with age, overall health and severity | Acute knee injuries |
| Healthdirect | A long period of rehabilitation, and possibly surgery | ACL rupture |
Healing Is Not Capacity
Those figures describe healing. They don't tell you when you can safely kneel on concrete or climb a ladder all day.
Swelling Takes Time
Queensland Health adds that swelling and bruising can take a few weeks to settle, so a puffy knee at week two isn't unusual. Your job may need a longer or shorter window than the general ranges suggest.
Wording Restrictions an Employer Can Act On
A GP can only write what the assessment supports. Within that, specific wording gives your supervisor something to roster around.
Graduated Return for Physically Demanding Work
Healthdirect advises letting your body guide you as you return to normal activities, and avoiding vigorous exercise while the knee heals. A serious injury may need physiotherapy and a guided rehabilitation program.
A Stepped Return
For physical jobs, that often means a stepped return: start with reduced hours or lighter tasks, then return to full duties as the knee improves. If the injury happened at work, your employer may need a WorkCover certificate of capacity instead.
A Ladder Injury
A tradesperson twists a knee while stepping off a ladder and is told to see an in-person clinician. Once they've been assessed, the GP can set restrictions around the tasks the injury rules out, and add a review date.
| Task at work | What the knee has to do | Wording a certificate might use |
|---|---|---|
| Shelf stacking from low racks | Bend and squat | No squatting or kneeling for the period |
| Delivery or site work | Climb steps and ladders | No ladders; stairs only with a handrail |
| Retail or reception | Stand in one spot | Standing limited to short periods, with seated breaks |
| Driving a work vehicle | Operate pedals | Discuss with the GP before returning |

Frequently asked questions
View all FAQsA telehealth GP can't physically examine your knee during the consult. If you haven't seen anyone yet, an in-person assessment is usually the first step. Once you know what's wrong, or while you wait for results, the GP can assess what you can manage at work and document it.
If you can't work at all, a sick leave certificate covers the time off. If you can do some work with limits, a fitness for work certificate records those restrictions for your employer. The GP recommends the right document after hearing about your injury and your duties.
Ask the GP during the consult. It depends on which knee is hurt, the type of vehicle and whether you can brake safely in an emergency. If your job involves driving, say so, because it may affect the restrictions. Some people need a lift or public transport for a while.
Stop the task that's aggravating it and tell your supervisor. Note what you were doing and when the pain increased, then book a review so the GP can reassess your restrictions. If any of the urgent signs described above appear, get emergency care instead of waiting for a consult.
It can. If a physiotherapist is treating you, share their recommendations with the GP at your next consult. The GP considers that advice alongside your own report of what you can manage. Restrictions usually change in steps, so expect updates as your knee improves.

A knee injury can limit standing, walking, climbing and kneeling at work. A GP can assess what you can safely do and, where appropriate, certify time off or restrictions. A badly swollen or misshapen knee, or a red, hot knee with fever, needs an emergency department.
