Is Fatigue Normal After Knee Replacement Surgery?
Fatigue is one of the common problems people experience following total knee replacement (TKR). It is also linked to heart and respiratory issues. Fatigue can occur at any point throughout the recovery period. However, it is most common in the first few days following surgery, depending on how well a patient responds to anesthesia and pain medication.
Moreover, daily activities such as work, physical treatment, and chores can leave you fatigued at the end of the day. It’s normal to feel tired on occasion, but if weariness becomes a serious issue in your everyday life, there may be more to the matter than you know.
You should expect to be fatigued following surgery, but if you are completely exhausted, you should go to your surgeon for more guidance.
What Are the Causes of Fatigue After Total Knee Replacement?
Some people don’t feel tired after the operation, but most TKR patients feel it. Typically, people believe that postoperative fatigue results from anesthesia. However, it is not a matter of fact, as most patients feel lethargic even months after surgery. It is generally due to lack of physical activity or carelessness after post-operation.
Anyhow, the following are the few main factors that can result in postoperative fatigue.
- Anemia—Blood loss during the operation
- Lack of proper sleep
- Irritable pre-surgery nerves (aggression, stress, depression)
- Pain killers and other prescribed medicines during or after surgery
- Lack of nutrition during or after the surgery
- Lack of physical movement and exercise
- Lack of muscle strength
- Physiological changes in the blood vessels and blood
Apart from these, physical and psychological stress, as well some allergic reactions, may result in extreme fatigue after total or partial knee replacement.
How Long Does Post-Surgical Fatigue Last?
It is natural to feel weary following surgery, but this should improve as your body recovers over time. Typically, 5 to 7 days in the hospital is required for a person to feel better. However, some people may require more time to recover.
It depends significantly on age, general health, and operation type. Anyhow, if you follow after-surgery precautions and take your medicines properly, you are more likely to assemble energy and build up muscle strength.
However, if you suffer from dreadful fatigue that hinders you from doing your daily life activities or is getting worse day by day, it is not normal TKR fatigue.
Treatment for Fatigue After Total Knee Replacement
Normally, postoperative fatigue gets normal day by day. Still, if the condition continues or worsens with time, it may indicate a knee infection, drug interaction, iron deficiency anemia, or stress. Whatever the situation causes you to feel tired, you should let your surgeon know your condition to avoid any worse condition.
Here are some treatment options for quick relief of fatigue after TKR.
- Try to stay hydrated after surgery. For this, you should drink plain water. Moreover, fresh fruit juices can also help you in gaining energy. However, don’t consume tea, coffee, or alcohol after surgery. Although these fluids can improve fatigue, they may result in a crash. Therefore, say a clear no to caffeine or alcoholic beverages.
- Don’t overdose on your medicines. Ask your doctor for only painkillers, as medications can cause fatigue.
- After surgery, exercising too soon will most likely set you back rather than improve your condition. Instead, consult with your physician about your recovery strategy and work together to set reasonable goals.
- Eat well, nutritious food, mainly focusing on iron. Food such as leafy green vegetables, fish, chicken, nuts, and fortified cereals are rich in iron. The iron-rich diet helps increase the hemoglobin level, which prevents iron deficiency and related fatigue.
- Mostly, fatigue and restlessness after surgery are due to lack of sleep, either due to pain, irritation, or stress. However, quality sleep has an influential role in the recovery of your knee replacement wound. Therefore, improve your sleep quality to reduce surgery-related fatigue.

What Not to Do After Knee Replacement?
Many people do not follow the surgeon’s instructions properly, and the consequences result in knee dislocation or severe pain that may turn into chronic pain.

After that, your knee is more likely to be fixed in place; thus, it has minimal chances of displacement.

What to Expect 5 Months After Knee Replacement?
Three to 5 months after knee replacement is quite challenging and rewarding. Indeed, every day, you will feel better. Most people see a reduction in pain and exhaustion as the weeks pass.
With each passing week, you should be able to walk more freely and farther, but it could be two months or more before you can walk properly again. You may still need a cane or crutches, but your doctor works with you to get you off those aids.
Anyhow, in some cases, you may get joint infection months after knee replacement due to a lack of post-operative precautions. In these cases, antibiotics and anti-inflammatory drugs can help. However, first, consider an appointment with your doctor to avoid consequences.
Why do I feel so tired after my knee replacement surgery?
