How to manage a swollen knee in the hemophilic patient?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello Doctor,

I am a patient with hemophilia and experienced a swollen knee after a minor bump yesterday. The swelling has now increased to the size of a grapefruit, and I am unable to bend the knee at all. I administered a double dose of Factor VIII – Antihemophilic factor class, but the pain remains severe at eight out of ten.

I have also tried ice application, elevation, and compression, but nothing seems to help. I am supposed to start a new job on Monday, and at this point, I cannot even walk.

I urgently need a solution. Should I go to the Emergency Room tonight?

Kindly help.

Hello,

Welcome to icliniq.com.

I have read your query and can understand your concern.

1) Why is this urgent?

A swollen knee the size of a grapefruit likely indicates a joint bleed (hemarthrosis), which is a medical emergency in patients with hemophilia.

A double dose of Factor VIII – antihemophilic factor (coagulation factor replacement therapy) did not help, which may mean a repeat or higher dose is needed, or the bleeding is still ongoing.

Severe pain rated eight out of ten, along with immobility, increases the risk of permanent joint damage if not treated promptly.

2) Why you should not wait:

Delayed treatment can result in:

Permanent joint damage.

Compartment syndrome, a serious complication due to increased pressure inside the joint

3) The emergency room can provide:

Additional factor VIII (antihemophilic factor) with monitoring of blood levels.

Joint aspiration, if necessary, is performed by a trained hematologist or orthopedic specialist.

Stronger pain control measures.

Imaging such as ultrasound or MRI to confirm whether it is a bleed or another type of injury.

4) What to do now:

Go to the Emergency Room immediately and inform the staff that:

You are a patient with Hemophilia.

You suspect an acute joint bleed.

You have already taken a dose of Factor VIII, but it was not effective

Bring the following with you:

The name and dosage details of your Factor VIII (antihemophilic factor) product.

Your hemophilia treatment card or any letter from your hematologist, if available.

I hope this helps.

Thank you.
