It is a totally different experience when you feel “weak in the knees” when you think of someone you like in the romantic sense.
But, if your body is showing actual signs of weakness in your knees, it cannot be a good sign. The knee is the largest joint in the human body and probably the most complex one, too.
Your knees take the weight of your entire body but, at the same time, make movements like bending and turning possible with ease.
A pain in your knees can be quite a hard thing to face irrespective your age. Osteoarthritis – a degenerative joint disease that occurs due to the wearing out of protective tissues at the ends of the bones – causes pain in the knees.
The good news is that there are several things you can do to reduce the effects of osteoarthritis of the knees like managing weight, exercising, reducing strain on the knees, etc.
Most patients with knee pain caused due to osteoarthritis can benefit from the knee exercises if done regularly and correctly. Let’s examine the types of exercises osteoarthritis (of the knee) patients should consider doing on a regular basis.
Of Exercises For Knee Osteoarthritis
Most people with knee osteoarthritis may be under the impression that exercising can only worsen the pain than provide them relief.
However, this is not true. Exercises that are not too intense can help strengthen the knees and the areas around the knees.
There are different kinds of exercises that an individual with osteoarthritis knee can perform to manage the pain. Some of these exercises include the following:
- Knee stretches: These are stretching exercises that improve the flexibility in the knee joint and its surrounding muscles. This can help reduce pain and stiffness too.
- Knee strengthening exercises: As the health condition causes pain and weakens the knee joint, knee strengthening exercising help build the muscles around the knee, thereby, restoring strength in and around the knees.
- Aerobic workouts: Aerobic exercises improve your heart health and increase your lung capacity. Depending on the severity of the knee condition, patients are recommended to perform 150 minutes of moderate-intensity aerobic exercises per week or 75 minutes of high-intensity aerobic workouts per week.1
