“Although Knee Replacement surgery has established itself as a safe and common procedure with excellent and predictable results, there is still a lot of confusion and doubts among the general population”, says Dr Firoz Ahmed, a leading Knee Replacement surgeon in Guwahati.

In this post, he tries to clear away the common myths surrounding the surgery.

❌ Myth 1: Knee replacement is only for very old people

✅ Fact: Age is not the most important factor…

❌ Myth 2: You have to wait until the pain becomes unbearable

✅ Fact: Waiting for too long can result in worsening of the deformities as well as muscle wasting. These can hamper full results after operation. Secondly, patients have to unnecessarily endure pain and disability till the time they actually undergo the procedure leading to loss of productive time.

❌ Myth 3: Knee replacement is very risky

✅ Fact: With advancement in modern medicine, anaesthesia and rehab procedures, Knee Replacement has become very safe and have predictable results.

❌ Myth 9: Knee replacement means you can’t sit or bend at all

✅ Fact: You can sit, bend, and perform most daily activities. Deep squatting or sitting cross-legged may be limited.

❌ Myth 10: Surgery is the only solution for knee pain

✅ Fact: Knee replacement is done only when non-surgical treatments like medications, injections, physiotherapy etc fail. Dr Firoz Ahmed believes that surgery should be done as the last resort and all other therapies should be given due chance in all patients.
