Knee stiffness is a typical symptom of chronic knee pain, defined by reduced mobility and discomfort in the knee joint. It often limits daily activities, making simple tasks like walking, standing, or bending challenging. Recognizing and addressing knee stiffness early can significantly improve quality of life and prevent further joint deterioration.

What is Knee Stiffness?

Knee stiffness refers to the reduced ability to move the knee freely, often accompanied by tightness or resistance. This symptom is particularly common in the morning or after periods of inactivity, such as sitting for long hours. For those with underlying joint conditions such as osteoarthritis, stiffness results from structural changes in the joint and surrounding tissues.

How Joint Conditions Causes Knee Stiffness

Degenerative joint diseases, such as osteoarthritis, can lead to cartilage breakdown and other structural changes, directly contributing to stiffness.

1. Cartilage Loss

When protective cartilage wears away, the bone surface becomes rough and exposed, making joint movement less smooth and increasing friction and resistance.

2. Inflammation

Inflammation causes the tissues around the knee joint to swell, which can compress the nerves and limit the joint’s range of motion. This makes bending or straightening the knee difficult.

3. Joint Effusion (Fluid Buildup)

The excess fluid in the knee, sometimes called “water on the knee,” creates increased pressure, compressing the surrounding tissues, including nerves, tendons, and ligaments.

4. Bone Spurs (Osteophytes)

Bony growths can grow into the knee joint space, physically limiting the knee’s range of motion.

5. Muscle and Ligament Tightness

Chronic pain leads to reduced activity, causing the muscles and ligaments around the knee to weaken and tighten, leading to reduced range of motion and stiffness.

When is Knee Stiffness Most Noticeable?

• Morning Stiffness: Common in joint conditions like osteoarthritis, lasting up to 30 minutes or more upon waking.
• Post-Inactivity Stiffness: Occurs after sitting or lying down for extended periods.

Activity-Related Stiffness: Worsens after prolonged use of the joint.

Diagnosing Knee Stiffness from Underlying Conditions 

A comprehensive evaluation helps identify the root cause of knee stiffness, particularly if degenerative joint conditions like osteoarthritis are suspected.

• Medical History: Evaluation of symptom patterns, lifestyle factors, and any history of joint conditions.
• Physical Examination: The knee’s range of motion, muscle strength, and signs of swelling or tenderness is thoroughly examined.

•  Imaging Tests:  X-rays can detect cartilage loss, joint space narrowing, and bone spurs, while an MRI offers detailed images of the soft tissues, such as ligaments and cartilage.

• Laboratory Tests: Tests like knee joint fluid analysis can rule out infections or inflammatory diseases like rheumatoid arthritis.

Treatment Options for Knee Stiffness

Relieving knee stiffness involves addressing the underlying causes, improving joint mobility, and reducing discomfort.

Non-Surgical Treatments

• Physical Therapy: Focuses on stretching and strengthening the muscles around the knee to enhance mobility.
• Medications: NSAIDs and pain relievers reduce inflammation and ease stiffness.
• Lifestyle Adjustments: Weight management and low-impact exercises, such as swimming or cycling, minimize strain on the knee.

Assistive Devices

• Braces or orthotic inserts provide support and improve joint alignment.

Advanced Procedures: Genicular Artery Embolization (GAE)

Genicular Artery Embolization is a minimally invasive procedure that targets inflammation in the knee, a key contributor to stiffness in conditions like osteoarthritis. GAE alleviates stiffness and pain without surgery by reducing abnormal blood flow in the joint.

Genicular Artery Embolization for Knee Stiffness

GAE is an FDA-approved treatment for chronic knee pain symptoms, including stiffness.

Benefits of GAE:

• Long-Lasting Pain Relief: Reduces inflammation and improves mobility long-term.
• Non-Surgical Solution: Ideal for patients seeking to delay or avoid knee replacement.

Rapid Recovery: Minimal downtime allows patients to resume activities within the first few days after the procedure.
