Knee joint osteoarthritis is one of the most common joint problems experienced by adults, especially older individuals. This condition occurs when the cartilage that cushions the knee joint gradually wears down, leading to pain, stiffness, and difficulty walking. Hip & Knee Consultant Orthopedic Specialist at Mandaya Royal Hospital Puri, dr. William Chandra, Sp.OT (K) Hip & Knee, explains what actually happens inside an arthritic knee and what causes the condition.

Causes of Knee Joint Osteoarthritis According to dr. William Chandra

In his explanation, dr. William states that osteoarthritis of the knee begins with damage to the cartilage inside the joint.
“Knee osteoarthritis occurs when the cartilage or soft tissue inside the knee joint becomes thinner, causing the joint space to narrow,” said dr. William. “This narrowing leads to pain, cracking sounds, deformities such as O-shaped or X-shaped legs, and eventually difficulty walking.”
Furthermore, dr. William emphasizes that knee osteoarthritis is not caused by a single factor. Instead, it results from a combination of several contributing aspects, including:
- Genetic factors: Family history can increase the risk of osteoarthritis.
- Age: Cartilage naturally thins as a person gets older.
- Previous injuries or accidents: Trauma to the knee can accelerate cartilage damage.
- Excess body weight: Extra weight increases pressure on the knees, speeding up joint wear.
This explanation highlights that knee osteoarthritis is a complex condition influenced by various aspects of a patient’s health.
