When Should I Worry About Swelling After Knee Surgery?
Undergoing a knee surgery, whether a total knee replacement, partial knee replacement, or another procedure, is a significant event for your body. During the surgery, your surgeon has to cut through skin, soft tissue, and bone to access and repair the joint.
This controlled trauma triggers a natural inflammatory response from your body, which can lead to significant swelling and pain after the operation.
When should I worry about swelling after knee surgery? It’s important to monitor your symptoms and consult your surgeon if you experience excessive or prolonged swelling, as this could indicate complications. Always follow your surgeon’s post-operative care instructions to ensure the best recovery.
Causes of Swelling After Knee Surgery
After any surgery, your body releases chemicals that cause changes to your blood vessels, usually widening them. This allows more white blood cells, fluids, and other healing components to reach the surgical site and begin the repair process.
In the case of knee surgery, the excess fluids that accumulate around the joint are the primary cause of the swelling. During the procedure, your surgeon has to cut into the joint capsule, which is the protective lining around the knee joint. This disruption allows fluids to build up in the area, leading to inflammation and swelling.
When should I worry about swelling after knee surgery? It’s crucial to monitor the extent and duration of swelling. If you experience severe, persistent, or increasing swelling, it could be a sign of a complication. Similarly, when should I worry about swelling after surgery in general, it’s important to consult your healthcare provider to ensure that the swelling is within expected limits and to address any potential concerns promptly.
The duration and severity of the swelling can vary depending on several factors:
Age – Recovery may be slower for older patients.
Underlying conditions – Conditions like diabetes or obesity can prolong swelling and healing.
Extent of surgery – More complex or invasive procedures usually result in more swelling.
Physical therapy – Staying active with PT exercises can help reduce swelling.
Use of compression stockings – Wearing compression socks/sleeves can minimize fluid buildup.
How Long Should the Swelling Last?
Moderate to severe swelling is expected in the first few days and weeks after knee replacement surgery. Most patients will experience significant swelling up to 3 months following the procedure.
During this initial recovery period, swelling may fluctuate in severity. Factors like activity level, use of ice/compression, and medication can all impact the swelling. Patients should expect mild to moderate swelling up to a year after surgery as the joint continues to heal.
Gradual improvement in swelling is a good sign that the body is progressing through the natural healing process. However, if you notice sudden or worsening swelling, especially in the lower leg or foot, you must contact your surgeon immediately.
When Should I Worry About Swelling After Knee Surgery?
Mild to moderate swelling around the incision site and the knee joint is typical after knee surgery.
However, in some cases, swelling may signify a more serious underlying condition that necessitates immediate medical evaluation. When should I worry about swelling after knee surgery? Here are key signs to look for:
Sudden, severe swelling – Any abrupt increase in swelling, especially if it’s accompanied by pain, redness, or warmth, may signify a complication like an infection or blood clot. Your surgeon should evaluate this immediately.
Swelling in the lower leg or foot – Swelling that develops in the calf, ankle, or foot could be a sign of a blood clot, also known as deep vein thrombosis (DVT).
Symptoms of DVT include:
- Leg or calf pain unrelated to the surgical site.
- Observe any tenderness or redness near the knee.
- Monitor for swelling in the calf, ankle, or foot.
In rare cases, a blood clot can travel to the lungs, causing sudden chest pain, shortness of breath, and coughing.
Ongoing, significant swelling: If the swelling in your knee and surrounding area remains severe or worsens over several weeks, it could be a sign of an infection or other complication. Your surgeon may need to examine the joint and order imaging tests.
Swelling that doesn’t gradually improve over time – While some levels of swelling may persist for up to a year, you should see steady progress in reducing the inflammation. Lack of improvement or worsening swelling is a reason to contact your doctor.
