Common Causes of Knee Pain
Knee pain can develop for many reasons, from temporary overuse to injuries or age-related joint changes. Some common causes include:
- Runner’s Knee (Patellofemoral Pain Syndrome) – Pain around or behind the kneecap, often caused by repetitive running, squatting, or climbing stairs.
- Arthritis – Osteoarthritis can gradually wear down cartilage, causing pain, stiffness, swelling, and reduced movement.
- Knee Injuries – Sprains, strains, ligament tears (such as ACL injuries), and meniscus tears can cause sudden pain and swelling.
- Tendonitis – Inflammation of a tendon, particularly the patellar tendon, can cause pain below the kneecap.
- Bursitis – Inflammation of small fluid-filled sacs around the knee can lead to tenderness and swelling.
- Gout – A buildup of uric acid crystals can trigger sudden, intense knee pain, redness, and swelling.
- Overuse – Repetitive activities or a sudden increase in exercise can strain the muscles, tendons, and joints.
- Muscle Weakness or Imbalance – Weak thigh or hip muscles can place extra stress on the knee.
- Excess Body Weight – Greater load on the knee joint can increase stress and contribute to pain, particularly over time.
- Other Joint Conditions – Rheumatoid arthritis and other inflammatory or autoimmune conditions can also affect the knee.
Important: Persistent, severe, or rapidly worsening knee pain—especially after an injury or when accompanied by significant swelling, redness, fever, or inability to bear weight—should be evaluated by a healthcare professional.
