Knee Stiffness: A Symptom of Osteoarthritis
Imagine waking up to a knee that feels like it’s been encased in ice – creaky, immovable, and protesting against even the simplest bends. Knee stiffness is a common symptom associated with osteoarthritis (OA) of the knee, a degenerative joint disease that primarily affects the cartilage in the knee joint. This gradual wearing down of the protective cartilage in the joint disrupts the smooth gliding motion we take for granted, leaving behind a sense of constraint and discomfort. Whether it’s morning stiffness or the initial struggle to rise from a chair, knee stiffness can impact everyday life and your mobility. Understanding the link between knee stiffness and OA is important for early detection and effective management.
Knee Stiffness Symptoms
One of the most common early symptoms of knee stiffness is morning stiffness, where your knee feels stiff and achy for the first 30 minutes to an hour after waking up. You might also experience a feeling of tightness or difficulty bending your knee, especially after sitting for a prolonged period. Other common symptoms may include:
- Creaking or grinding sounds
- A feeling of instability or weakness in the knee
- Difficulty bending or straightening the knee
- Pain in the knee, which may be worse with movement
- Reduced range of motion
- Swelling and inflammation
Knee Stiffness Causes
One of the most common causes of knee stiffness is osteoarthritis of the knee, which causes the breakdown of cartilage and bone in the knee joint. However, knee stiffness can also be caused by a variety of factors, ranging from minor muscle strain to injuries Here are some of the other common causes of stiffness in the knee:
- Bursitis
- Fractures
- Gout
- Knee ligament injuries
- Meniscus Injuries
- Rheumatoid arthritis
- Tendonitis
How Does Osteoarthritis Cause Knee Stiffness?
Osteoarthritis can cause knee stiffness in several ways. The primary cause of knee stiffness in osteoarthritis is the breakdown of cartilage, the smooth, slippery cushion that lines the ends of your bones in the knee joint. This gradual wear and tear reduces the cushioning and gliding effect, leading to friction and stiffness when you move your knee. As the cartilage deteriorates, the underlying bone is exposed, triggering an inflammatory response. This inflammation causes swelling and thickening of the joint tissues, making it harder for the bones to move freely and contributing to stiffness.
OA can also cause the joint capsule, a fibrous membrane that surrounds and protects the knee joint, to become stiff over time. This tightening restricts the range of motion in your knee, making the stiffness in your knee even worse. The pain and discomfort associated with osteoarthritis can also lead to decreased use of the muscles around the knee. This muscle weakness and imbalance can make it harder to stabilize and move the joint, contributing to stiffness and difficulty initiating movement. In response to the damage and instability in the joint, your body may try to compensate by forming bony outgrowths called osteophytes, also known as bone spurs. These bony bumps can impinge on surrounding tissues and limit the range of motion in your knee, leading to increased stiffness. The severity and specific pattern of knee stiffness in osteoarthritis can vary depending on the extent of cartilage damage, the location of the affected joint area, and individual factors like age and activity level.
Stiff Knee Treatment
A stiff knee due to osteoarthritis can be quite uncomfortable and limit your mobility. Thankfully, there are a variety of treatment options available to help manage your symptoms and improve your quality of life. Our affiliated interventional radiologists at American Knee Pain Centers perform genicular artery embolization, a minimally invasive procedure that offers relief from knee pain and stiffness. Alongside this treatment, our affiliated physicians offer recommendations for lifestyle changes to improve flexibility and the overall health of your joints.
Lifestyle Changes
If you’re experiencing knee stiffness due to osteoarthritis, your doctor may suggest lifestyle modifications to help manage your symptoms. Some common lifestyle changes are maintaining a healthy weight to put less stress on your knees, avoiding activities that could cause more pain and stiffness, stretching and strengthening your muscles, applying ice or heat to your knees to help reduce inflammation, and wearing supportive shoes to help protect your knees from impact.
GAE: Knee Replacement Alternative
Genicular artery embolization (GAE) is a minimally invasive treatment that is an alternative to knee replacement surgery. It involves blocking the blood flow to the genicular arteries, which play a crucial role in supplying blood to the knee joint. Our experienced medical team utilizes advanced imaging technology to precisely identify the genicular arteries contributing to your knee pain and stiffness. A small catheter is then inserted and guided down to the arteries that supply blood to the tissue that lines the knee. Tiny particles are then injected into the arteries to slow the blood supply to the joint, resulting in relief from knee pain and stiffness, and enhancing your mobility.
