Knee pain becomes increasingly common with age, but pain on the inside of the knee should not automatically be attributed to arthritis.

Osteoarthritis can cause gradual pain, stiffness, reduced mobility, and discomfort during weight-bearing activities. Changes may affect different parts of the knee, including the medial compartment.

Previous injuries can also contribute to later knee problems. A history of meniscus or ligament injury may influence joint health over time.

Another possibility is an ongoing meniscus problem. Degenerative meniscus changes become more common with age and can sometimes produce pain around the joint line.

Pain below the inner knee may instead involve bursae or tendons.

The pattern of symptoms matters. Arthritis often produces stiffness and activity-related discomfort, while an acute meniscus injury may be associated with a specific twisting event, catching, or swelling.

Treatment for arthritis can include exercise, strengthening, weight management when appropriate, physical therapy, and medications or procedures when recommended.

The goal is not necessarily to avoid all activity. Appropriate movement can be an important part of maintaining function.

If inner knee pain interferes with walking, sleeping, exercise, or daily activities, a healthcare professional can help determine whether arthritis or another condition is responsible.
