What are the Causes of Knees Stiffness after Sitting?
Knee Stiffness after Sitting Caused By Osteoarthritis of the Knee:
There are some people who can experience knees stiffness even after sitting for a couple of minutes. And then there are some people who have knees stiffness after sitting for prolonged periods of time. This should not be taken lightly, as this can be a sign of osteoarthritis.2 In the initial stages, the knee stiffness will subside in a couple of minutes and the person will be able to go about his/her daily activities without any further stiffness or pain. However, as the damage to the knee joint increases, the knee stiffness also worsens and needs medical attention.
Osteoarthritis of the knee joint is characterized by damage to the cartilage which covers the bones. This leads to rubbing of the bones of knees against each other upon movement resulting in pain. As the Knee Osteoarthritis worsens, patient starts to experience knee stiffness after sitting, pain in the knees with walking and limited knee movements. Osteoarthritis of the knee gradually progresses and it takes some years for the cartilage of the knee joint to get damaged. Elderly people are commonly diagnosed with Knee Osteoarthritis.
Knee Stiffness after Sitting Caused By Chondromalacia Patellae:
Chondromalacia patella is a medical condition where there is damage to the cartilage present just below the kneecap. As the patient moves, the kneecap does not sit in its proper position and rubs against the cartilage causing inflammation, pain and damage of the knee joint and also resulting in knee stiffness. There are some individuals who are at an increased risk for developing chondromalacia patellae and these people include soccer players, runners, jumpers etc. People who have suffered from trauma or accident which causes damage to their kneecap have an increased likelihood for developing chondromalacia patellae.
Knee Stiffness after Sitting Caused By Knee Bursitis:
Knee stiffness after sitting which is also accompanied with swelling can be an indication of knee bursitis. Bursitis is a condition where there is inflammation of the bursae, which are the small fluid-filled sacs that act as shock absorbers for the knee joint. Bursitis is commonly caused by trauma, repetitive motion injuries and infection
Knee Stiffness after Sitting Caused By Excess Synovial Fluid:
Synovial fluid is present in all the joints of the body and its function is lubricating the cartilage and reducing friction and providing resiliency against damage. If there is insufficient amount of synovial fluid present, then it causes unnecessary stress or wear and tear on the knee joint which leads to knee stiffness and restriction of movement.
If there is excessive synovial fluid present due to some imbalances; or if inflammation is causing accumulation of synovial fluid, then it also causes knee stiffness after sitting and swelling in the knee. Some of the causes of excessive synovial fluid include arthritis, gout, injury and infection.
How is the Cause for Knee Stiffness after Sitting Diagnosed?
The treatment of knees stiffness normally depends on the underlying cause. For diagnosis of what is causing knee stiffness after sitting, the tests and examinations which are done include: blood tests, x-ray, MRI scan and arthroscopy.

It is important to partake in moderate physical activities or exercises to help strengthen the muscles around the knee joint. However, before starting on any exercise regime, it is important to consult your doctor to get the go-ahead.
