How effective is knee arthroscopy for plica syndrome?

A plica is a fold of joint lining that can become irritated and rub as the knee bends. Similar pain can come from the kneecap, meniscus, tendon or joint surface, so symptoms alone do not prove plica syndrome. Arthroscopy allows the surgeon to inspect the joint and, when appropriate, remove or smooth an irritated plica. Relief is less predictable if another source of pain has not been addressed.

Before considering surgery, review the diagnosis and a focused rehabilitation plan. This may include reducing repeated deep bending for a period, restoring knee motion, and strengthening the thigh and hip while gradually rebuilding activity. If arthroscopy is proposed, ask what finding supports it, what other causes were excluded, and how the operation would change your rehabilitation. Follow skin and wound instructions carefully after any procedure.

Arrange prompt assessment for a hot or swollen knee, fever, inability to bear weight, a locked joint, or severe pain after a twist. Following arthroscopy, report increasing wound redness, discharge, fever, new calf swelling, breathlessness or a sudden loss of movement. Persistent clicking without functional limitation is different from a knee that truly locks and needs separate evaluation.

Ask how confident the diagnosis is, what rehabilitation has been tried, and whether imaging or examination suggests another pain source. Clarify the intended arthroscopic procedure, likely restrictions, physiotherapy milestones, and which symptoms should prompt an earlier review.
