What knee arthroscopy means

Knee arthroscopy is a keyhole procedure where a small camera and instruments are used to inspect and treat selected knee problems through small incisions. It is commonly discussed for ACL injury, meniscus tear, loose bodies, cartilage problems and selected sports injuries.

It is not required for every knee pain patient. The decision depends on symptoms, examination findings, MRI or X-ray reports and whether non-surgical care is likely to help.

Why patients choose specialist assessment

Knee pain after twisting injury, sports trauma, locking, giving way, recurrent swelling or inability to return to activity should be assessed by an orthopaedic surgeon. Early diagnosis helps avoid repeated instability and long-term joint damage in selected injuries.

At Jayam Hospital, knee arthroscopy assessment may include clinical tests, imaging review, treatment planning and rehabilitation discussion.

Recovery depends on the procedure

Simple diagnostic arthroscopy, meniscus trimming, meniscus repair and ACL reconstruction all have different recovery timelines. Patients should not compare recovery with another person unless the same condition and procedure were involved.

This article is for patient education only. Diagnosis, treatment choice and surgery suitability must be decided after consultation, examination and required investigations.

FAQs

Common questions

Is knee arthroscopy major surgery?

It is a minimally invasive keyhole procedure, but it is still surgery and requires proper evaluation, anaesthesia planning and rehabilitation.

Will every meniscus tear need surgery?

No. Some tears may be treated without surgery, while others may need arthroscopic repair or trimming based on symptoms and tear pattern.

How many days rest is needed?

Rest and return-to-activity vary by diagnosis and procedure. ACL reconstruction and meniscus repair usually need structured rehabilitation.
