QUICK SUMMARY Before knee replacement surgery in Madurai, patients at Muthu Hospital complete six essential pre-operative checks: heart health, infection screening, anaesthesia review, imaging, physiotherapy, and home planning. During surgery, Dr. Mithran follows a seven-step process — from anaesthesia to implant placement — inside a sterile operation theatre. Patients who understand each step beforehand feel more confident and recover faster.

Why Do Patients Feel Anxious Before Knee Replacement Surgery?

Most patients worry more about the process than the surgery itself. The unknown often feels bigger than the procedure. First, understand this: that anxiety is completely normal. In fact, it is one of the most common things Dr. Mithran hears from patients every week.

Dr. Mithran, Orthopaedic Surgeon at Muthu Hospital, Madurai, has performed knee replacement surgery on patients aged 35 to 98. Patients who understand the process beforehand consistently feel more confident and recover better than those who arrive unprepared.

This article explains what happens before and during knee replacement surgery in Madurai, step by step, so you know exactly what to expect.

What Happens Before Knee Replacement Surgery? The 6-Step Pre-Operative Process

Before any knee replacement surgery — partial or total — every patient at Muthu Hospital completes a full pre-operative assessment. Each step is essential for safety.
Good preparation improves recovery. Patients who arrive prepared and with home support recover faster and more smoothly.

Steps

Step	What happens	Why it matters
1	Day-of assessment: vitals, imaging, and fitness confirmed on the morning of surgery.	A final check ensures nothing has changed since the pre-operative assessment.
2	Anaesthesia applied — type confirmed by the anaesthesia team.	The patient is made fully comfortable and pain-free before the procedure begins.
3	Sterile setup: theatre, instruments, and patient all prepared under strict sterile conditions.	Sterile conditions prevent infection from entering the surgical site.
4	Incision: a precise cut opens the knee joint.	The surgeon gains direct access to the joint to work accurately inside it.
5	Cartilage removal: damaged cartilage on the thigh bone and shin bone is carefully removed.	In partial replacement, only the damaged condyle is resurfaced. In total, both are prepared.
6	Implant fitting: metal components fixed to prepared bone surfaces. Plastic spacer inserted between them.	The implant restores smooth joint movement and eliminates the source of pain.
7	Closure: wound closed and dressed. Patient moved to recovery room.	The operation is complete. Recovery and physiotherapy begin immediately.

Why Is Each Pre-Operative Step Necessary?

Why is a cardiac check required?

Knee replacement surgery involves anaesthesia, which places stress on the heart. A cardiac check confirms that the heart is fit for surgery. Blood pressure must be controlled before proceeding.

Why are infections treated before surgery?

Any infection in the body, even dental issues, can spread to the implant. This can cause serious complications. Treating infections beforehand prevents this risk.

Why is pre-operative physiotherapy important?

Strong muscles support the new joint. Patients who do physiotherapy before surgery walk earlier and recover faster.

Why is imaging necessary?

X-rays and scans show the extent of joint damage. This helps decide whether partial or total knee replacement is required.

What Tests Are Done Before Knee Replacement Surgery?

At Muthu Hospital, pre-operative tests include:

Blood tests
ECG (heart check)
Chest X-ray
Knee X-rays
MRI or CT scan (if required)
Blood pressure monitoring
Dental check

These tests ensure the patient is fit for knee replacement surgery in Madurai.

What Is the Best Preparation for Knee Replacement Surgery?

The best preparation combines physiotherapy and home planning.

Physical preparation

Start physiotherapy before surgery. Focus on strengthening thigh muscles. Daily walking also helps. Maintaining a healthy weight reduces stress on the knee.

Home preparation

Arrange help for at least 30 days. Avoid stairs if possible. Remove loose rugs to prevent falls. Keep essential items within easy reach.

Patients who prepare well recover faster and with fewer complications.

What Happens During Knee Replacement Surgery? The 7-Step Surgical Process

Knee replacement surgery at Muthu Hospital is performed in a sterile operation theatre. Dr. Mithran follows a standard process for every patient.

Step	What happens	Why it matters
1	Day-of assessment: vitals, imaging, and fitness confirmed on the morning of surgery.	A final check ensures nothing has changed since the pre-operative assessment.
2	Anaesthesia applied — type confirmed by the anaesthesia team.	The patient is made fully comfortable and pain-free before the procedure begins.
3	Sterile setup: theatre, instruments, and patient all prepared under strict sterile conditions.	Sterile conditions prevent infection from entering the surgical site.
4	Incision: a precise cut opens the knee joint.	The surgeon gains direct access to the joint to work accurately inside it.
5	Cartilage removal: damaged cartilage on the thigh bone and shin bone is carefully removed.	In partial replacement, only the damaged condyle is resurfaced. In total, both are prepared.
6	Implant fitting: metal components fixed to prepared bone surfaces. Plastic spacer inserted between them.	The implant restores smooth joint movement and eliminates the source of pain.
7	Closure: wound closed and dressed. Patient moved to recovery room.	The operation is complete. Recovery and physiotherapy begin immediately.

How Long Does Knee Replacement Surgery Take?

The duration varies. Partial knee replacement usually takes less time than total knee replacement. Patient condition also affects timing. The exact duration is explained during consultation.

What Is the Difference Between Partial and Total Knee Replacement Surgery?

Both procedures follow the same process. The difference is the extent of replacement:

Partial knee replacement: Only the damaged part is replaced. Recovery is faster.
Total knee replacement: The entire joint is replaced. Suitable when arthritis affects the whole knee.

What Happens Immediately After Knee Replacement Surgery?

Recovery begins immediately after surgery.

Day 1: Patients stand and walk with support. Early movement reduces stiffness and improves healing.
Days 1–5: Hospital stay with guided physiotherapy and pain management.
After discharge: Home physiotherapy continues for 30 days.

Recovery timeline

Day 15: Pain reduces
1 month: Daily activities improve
3 months: Return to normal lifestyle
