When is knee arthroscopy recommended for plica syndrome?

A plica is a fold of joint lining that can become irritated and rub during repeated knee bending. Pain near the kneecap, clicking, or tenderness can also occur with other knee conditions, so the diagnosis is clinical rather than based on one symptom. Rest from aggravating loads, targeted exercises, and treatment of movement factors are commonly considered first. Arthroscopy can allow the surgeon to inspect the joint and remove an irritated plica when the diagnosis and symptoms support that choice.

Track which activities provoke the rubbing or clicking and whether swelling follows. Complete the rehabilitation plan consistently, modify deep bending and repetitive impact as advised, and return gradually. Ask how the diagnosis was established and whether a different source of pain has been excluded. If arthroscopy is discussed, clarify the intended finding, the planned treatment, and the rehabilitation milestones.

Arrange prompt assessment for a knee that suddenly locks, cannot bear weight, becomes hot and swollen, or develops severe pain after an injury. Fever with a hot swollen joint also needs urgent medical attention. Persistent clicking alone does not establish that surgery is needed, but a change in function deserves review.

Ask whether the plica is the confirmed pain source, what non-surgical options remain, what arthroscopy would change, and how long normal walking and exercise may take afterward.
