Knee pain is most commonly caused by ligament injuries (ACL tears), meniscus damage, and overuse. Medical conditions such as osteoarthritis, rheumatoid arthritis, and bursitis are also major causes. Muscle weakness and excess weight can worsen or trigger knee pain over time.
Direct Answer
Knee pain is most commonly caused by injuries such as ligament tears, meniscus damage, or overuse. Medical conditions like osteoarthritis, rheumatoid arthritis, gout, and bursitis also frequently cause knee pain. Poor posture, muscle weakness, and excess body weight can contribute to ongoing discomfort.

Summary
Knee pain can stem from acute injuries or long-term degenerative conditions. The most common causes include ligament tears, cartilage damage, and arthritis. Identifying the underlying cause is the first step toward effective treatment.
Understanding Knee Pain
The knee is the largest joint in the body. It is made up of bones, cartilage, ligaments, and tendons that work together to provide stability and mobility. Because of this complexity, the knee is vulnerable to a wide variety of injuries and conditions.
Most Common Causes
- ACL Injury: A tear of the anterior cruciate ligament, often occurring during sports involving sudden stops or direction changes.
- Meniscus Tear: Damage to the cartilage that cushions the knee, often from twisting movements.
- Osteoarthritis: Gradual wear and tear of knee cartilage, most common in older adults.
- Bursitis: Inflammation of the fluid-filled sacs that cushion the knee joint.
When to See a Physiotherapist
Seek assessment if your knee pain persists beyond 2 weeks, is associated with swelling or instability, or is limiting your daily activities. A physiotherapist can identify the cause and create a personalised treatment plan.
