Knee pain can develop for many reasons, from everyday wear and tear to injuries or underlying medical conditions. For some, it starts as a mild discomfort that gradually worsens, while for others, it can appear suddenly after a specific injury. Understanding the cause of your knee pain is the first step in finding the right treatment.

Common causes of knee pain

• Osteoarthritis – The most common cause of knee pain, osteoarthritis occurs when the cartilage cushioning the knee joint wears down over time, leading to stiffness, swelling, and discomfort.
• Rheumatoid arthritis – An autoimmune condition that causes inflammation in the joints, leading to pain, swelling, and eventual joint damage.
• Meniscus tears – The meniscus is a rubbery piece of cartilage that cushions the knee. A sudden twist or injury can cause it to tear, leading to pain, swelling, and difficulty moving.
• Ligament injuries – Damage to the ACL, MCL, PCL, or LCL ligaments can cause instability, swelling, and pain, particularly after sports injuries.
• Patellar tendinitis – Common in people who run, jump, or play sports, this condition occurs when the tendon connecting the kneecap to the shinbone becomes inflamed.
• Bursitis – Inflammation of the fluid-filled sacs (bursae) that cushion the knee joint, often caused by repeated pressure or overuse.

Management strategies vary depending on the underlying cause, individual circumstances, and response to different approaches. Some people find that modifying activities, physiotherapy, or other treatments may help manage symptoms.
