What does knee arthroscopy treat?

A surgeon uses a small camera called an Arthroscope through small openings to inspect the knee and guide instruments. Depending on the findings, the procedure may trim or repair damaged tissue, remove an irritating plica, or treat another problem that can be reached inside the joint. It is not suitable for every knee pain problem, and it does not automatically reverse arthritis or replace a structured rehabilitation plan.

The decision considers your symptoms, examination, activity goals, and imaging. A Musculoskeletal MRI may help clarify soft-tissue findings before surgery, but the scan is interpreted alongside your history rather than used alone. Mechanical catching, locking, or persistent symptoms may prompt a more detailed discussion.

Ask what diagnosis the procedure is intended to address, what non-surgical options remain, and what recovery activities are expected. Before surgery, share your medicines, allergies, and medical conditions. Afterward, follow wound, walking, exercise, and follow-up instructions. Swelling and stiffness can occur during recovery; gradual rehabilitation helps restore movement and strength. Contact the surgical team if the plan or expected recovery is unclear.

Seek urgent advice after surgery for increasing redness or drainage, fever, severe calf pain or swelling, chest pain, breathlessness, or a foot that becomes cold, pale, weak, or numb. Before surgery, prompt assessment is needed for a locked knee, major deformity, or inability to bear weight after an injury.

Which structure is causing my symptoms? What would arthroscopy change? Could physiotherapy or another treatment be tried first? What recovery milestones, restrictions, and warning signs should I expect?
