Am I a Candidate

Not everyone with knee pain requires surgery, and understanding when surgical intervention may be beneficial is an important part of your decision-making process.

This section helps you understand when knee symptoms may benefit from specialist assessment. You’ll find a simple guide to the signs that may suggest a review is appropriate, along with the factors Dr Jonathan Negus considers when discussing whether surgery or non-surgical care may be suitable for you.

Signs You May Benefit From a Specialist Review

You may consider seeing a knee specialist if you experience:

  • Knee pain during walking or everyday activities
  • Pain that limits how far you can walk
  • Symptoms that continue despite rest or medications
  • Swelling that recurs or does not fully settle
  • Stiffness or reduced range of motion
  • Pain when climbing or descending stairs
  • Night-time pain or discomfort that affects sleep
  • Difficulty rising from a chair
  • Trouble putting on socks or shoes due to limited knee motion
  • A feeling of instability or the knee giving way
  • Catching, clicking, or locking sensations
  • Needing railings, a cane, or crutches for confidence
  • Difficulty walking longer distances without stopping

These symptoms can occur with osteoarthritis, meniscal tears, ligament injuries, cartilage damage, or patellar instability. An assessment helps clarify the cause, but it does not automatically mean that surgery is required.

When Surgery May Be Considered

Knee surgery may be discussed if symptoms:

  • Persist despite physiotherapy or exercise-based treatment
  • Interfere with daily function or confidence
  • Limit walking distance or activity levels
  • Cause ongoing swelling or stiffness
  • Are linked to mechanical locking or instability
  • Are associated with advanced degenerative changes on imaging

Any recommendation is based on your symptoms, examination findings, imaging, general health, and personal goals.

If you would like guidance about whether knee surgery may be appropriate for your situation, you can arrange a consultation with Dr Jonathan Negus, a specialist knee surgeon in Sydney.
