Knee Replacement
What is Knee Replacement?
Knee replacement is a surgical procedure that involves removing damaged or diseased parts of the knee joint and replacing them with artificial components, often made of metal, plastic, or ceramic. This surgery is typically performed to relieve pain and restore function in individuals with severe knee damage, particularly due to arthritis or injury.
How to diagnose Knee Replacement? When to consult a doctor?
Diagnosing the need for knee replacement surgery typically involves a comprehensive evaluation that includes a medical history review, physical examination, and diagnostic tests. The goal is to assess the severity of knee problems and determine if conservative treatments have been ineffective.
You should consult a doctor if:
- Persistent pain in the knee that does not improve with conservative treatments (like rest, ice, compression, or over-the-counter pain relievers) is a common indication for surgery.
- Ongoing swelling in the knee that is not responsive to treatment may indicate joint damage.
- A feeling of instability or the knee "giving out" during activities can be a sign of significant joint deterioration.
- If knee pain worsens at night, interfering with sleep, it may indicate that the joint is severely damaged.
