When Knee Replacement Should Be Avoided or Delayed

Introduction

Knee replacement surgery can significantly improve quality of life when done for the right reasons. However, it is not suitable for every patient with knee pain.

Understanding when knee replacement should be avoided or delayed is essential for long-term joint health.

Mild to Moderate Arthritis

Patients with early-stage arthritis often respond well to:

• Physiotherapy

• Weight management

• Activity modification

• Medications or injections

Surgery at this stage may not provide lasting benefit.

Pain Without Functional Limitation

Pain severity alone is not an indication for surgery. If daily activities remain manageable, surgery can often be postponed safely.

Uncontrolled Medical Conditions

Conditions such as uncontrolled diabetes, heart disease, or infections may increase surgical risk and require optimization before considering surgery.

Unrealistic Expectations

Knee replacement improves pain and function, but it does not restore a natural joint. Patients expecting to run or squat extensively may be dissatisfied despite technically successful surgery.

Conclusion

The decision for knee replacement should be individualized, based on symptoms, function, and response to conservative care rather than imaging alone.
