Right Knee Pain During Pregnancy: Causes and Solutions

Sharp pain on the right side behind the right knee?

Hello Doctor, when I was in the third and fourth grade of elementary school, I strained four ligaments in my right knee.
At that time, my family only took me to see a traditional Chinese medicine practitioner for herbal treatment and medication.
After I was able to walk again, I would experience knee pain whenever the weather changed.
I am currently 18 weeks, almost 19 weeks pregnant, and I work in the food service industry.
On the night of October 8th, I suddenly experienced severe stabbing pain on the right side of the back of my right knee, with a high frequency of pain.
I did not seek medical attention and rested at home for three days, after which it improved.
However, on the morning of October 20th, I was suddenly awakened by pain, which this time was very rhythmic, occurring approximately every hour, preventing me from sleeping all night.
I visited an orthopedic doctor, but since I am pregnant, the doctor only prescribed pain relief medication.
However, after taking it, I still experienced the same rhythmic stabbing pain.
I would like to ask the doctor if an X-ray can help identify the cause and provide treatment, or if this is related to my pregnancy.
Thank you, Doctor.

Dr. Wang Zhaomin reply Rehabilitation

Pregnant women are advised against undergoing X-ray examinations.
Due to the increased likelihood of musculoskeletal pain during pregnancy, unless there is an emergency or severe condition, conservative treatment should be prioritized.
It is recommended to consult with an orthopedic or rehabilitation specialist and discuss with an obstetrician-gynecologist to receive appropriate care.

More Info

Understanding knee pain during pregnancy can be complex, especially when there is a history of previous injuries, such as ligament strains. In your case, the sudden onset of sharp pain in the right knee, particularly after a period of rest, could be attributed to several factors, including the physiological changes that occur during pregnancy, as well as the residual effects of your earlier knee injury.

Firstly, during pregnancy, a woman's body undergoes significant hormonal changes, particularly the increase in relaxin, which helps prepare the body for childbirth. This hormone causes ligaments to become more lax, which can lead to instability in the joints, including the knees. The added weight and changes in posture that come with pregnancy can also place additional stress on the knees, leading to pain and discomfort. This is particularly relevant for someone in the service industry, where prolonged standing and physical activity can exacerbate knee issues.

The sharp, recurrent pain you are experiencing could also be related to the previous ligament injury you sustained in childhood. If the ligaments were not fully rehabilitated, they might be more susceptible to strain during pregnancy, especially with the added weight and changes in your body mechanics. The pain you describe, occurring in a regular pattern, could suggest that certain movements or positions are aggravating the knee, possibly due to the altered biomechanics during pregnancy.

Regarding your question about imaging, it is generally advised that pregnant women avoid X-rays unless absolutely necessary due to the potential risks to the developing fetus. Instead, conservative management is often recommended. This may include physical therapy, which can help strengthen the muscles around the knee, improve stability, and alleviate pain. A physical therapist can provide tailored exercises that are safe during pregnancy and can help address any biomechanical issues contributing to your pain.

In addition to physical therapy, other conservative treatments may include:
1. Rest and Ice: Taking breaks from activities that exacerbate your pain and applying ice to the affected area can help reduce inflammation and discomfort.

2. Compression and Elevation: Using a knee brace or wrap can provide support, while elevating the leg can help reduce swelling.

3. Heat Therapy: After the initial inflammation has subsided, applying heat can help relax and soothe the muscles around the knee.

4. Gentle Stretching and Strengthening Exercises: Engaging in low-impact exercises, such as swimming or prenatal yoga, can help maintain overall fitness without putting undue stress on your knees.

5. Posture and Body Mechanics: Being mindful of your posture and how you move can significantly impact knee pain. Ergonomic adjustments at work, such as using supportive footwear and taking breaks to stretch, can be beneficial.

6. Consultation with Specialists: If the pain persists, consider consulting with a physical therapist or a specialist in maternal-fetal medicine who can provide more specific guidance tailored to your situation.

In summary, while pregnancy can certainly contribute to knee pain due to hormonal changes and increased physical demands, your history of knee injury may also play a significant role. A conservative approach focusing on physical therapy and lifestyle modifications is typically recommended, and imaging studies like X-rays should be avoided unless absolutely necessary. Always consult with your healthcare provider before starting any new treatment or exercise regimen, especially during pregnancy.
