What Are The Causes Of Knee Pain During Pregnancy?

Knee pain occurs in most women, but there are different reasons for knee pain during pregnancy.

  1. Hormonal changes: In your third trimester, the secretion of relaxiniXA hormone produced by the ovaries that help relax the muscles and joints during pregnancy and prepare the body for childbirth hormone loosens up the pelvic ligaments and tendons to prepare for childbirth. They will not only affect the ligaments of the pelvic region but also loosen the ligaments and tendons of the knees (1).
  1. Weight gain: The gradual increase in weight during pregnancy will exert strain on the knees, leading to knee pain. This is intense if it is your first pregnancy, as the body may not be able to bear the extra weight (2).

  1. Falls and injuries: Sudden falls, strain, or knee injuries as a result of the changing body will also result in knee pain (4).
  1. Walking or standing: Knee pain will also develop due to the extended periods of walking or standing when the knees are forced to carry excess weight for longer (5).
  1. Deficiency of calcium: The need for calcium increases during pregnancy (6), and might result in a deficiency if the body does not take the right amounts. It, therefore, raises the risk of knee pains.

Are There Any Complications Associated With Pregnancy Knee Pain?

If knee pain is not treated on time, it might lead to certain complications in the future.

  • Osteoarthritis, a degenerative joint disease, will develop in the later stages. According to data from the National Institutes of Health, it has been found that around 3.3 to 3.6% of the world’s population is affected by osteoarthritis. As a consequence, you may experience joint stiffness, pain, and locking of knee joints (7).
  • Damage in the protective cartilage and ligament around the knee joints could lead to difficulties in walking, running, and bending in the future (8).

Managing knee pain becomes essential to make pregnancy a comfortable time for the mom-to-be.

How To Manage Knee Pain During Pregnancy?

Here are a few ways in which you can try to alleviate knee pain during pregnancy (9).

  • Exercise: Low-impact exercises such as moderate walking and swimming will strengthen your quadriceps and offer support to your knees. They might, therefore, prevent knee pain.
  • Give some rest to your feet: Do not strain your feet too much and rest more as you start to gain weight while pregnant. It will help ease your knee pain.
  • Get the right shoes: Use shoes that are well-cushioned for proper arch support. The cushions act as shock absorbers and prevent knee pain during early pregnancy.
  • Manage your body weight: Try maintaining your weight as gaining weight too quickly is bad for the joints. On average, you can put around 15 to 25 pounds throughout pregnancy.
  • Use knee braces: Wear a knee brace that comes with a doughnut hole in the center when you are walking or indulging in other physical activities. They offer support to the loose ligaments and tendons around the knee and help to control the pain.

  • Massage therapy: Getting massage therapy will help in relieving joint pains and stiffness. They also help in improving the range of motion.
  • Improve your diet: Include a balanced diet of all essential nutrients. Increase the intake of omega-3 fatty acids, calcium, and vitamin D to relieve joint pains and stiffness.
  • Rest well: Take enough rest as it helps ease joint or knee pains.

If the above measures do not work and the pain worsens, you need to visit your obstetrician for proper medical treatment.
