Revision Knee Replacement: Second Opinion

WHAT IS REVISION KNEE REPLACEMENT?

Understanding Why Reconstructive Surgery is Needed

Most modern knee replacements last 15–20 years or longer when correctly performed and properly looked after. But implants are not permanent. Over time, mechanical forces, biological changes, or complications can cause a previously functioning replacement to fail — resulting in pain, instability, or loss of function that requires surgical correction.

Revision knee replacement reconstructs a failed primary knee replacement. It is significantly more complex than primary surgery and is required when implants loosen, become infected, or otherwise fail to function correctly.

WHY DO KNEE REPLACEMENTS FAIL?

The Two Most Common Causes for Revision Surgery

1. Implant Loosening (Aseptic)

Over time, the bond between the implant and the bone can weaken. This is called aseptic loosening — loosening without infection.

The patient experiences a return of knee pain, often described as a deep ache that worsens with activity, sometimes with a feeling of instability or movement in the knee. X-rays show the implant shifting position relative to the bone.

Why Loosening Occurs: More likely with higher activity levels, higher body weight, and implants placed with suboptimal alignment. Robotic precision in primary surgery significantly reduces this risk.

2. Deep Infection

Periprosthetic joint infection — infection around the knee implant — is one of the most serious complications in joint replacement surgery and one of the most complex problems to treat.

Deep infection does not resolve with antibiotics alone. It typically requires surgical intervention — sometimes in two stages, where the infected implant is removed, an antibiotic spacer is placed for several weeks, and then a new implant is inserted once the infection has been eradicated.

Important Warning: Any patient with a joint replacement who develops unexplained fever, knee pain, swelling, or wound changes should seek immediate assessment.

HOW COMPLEX IS REVISION KNEE REPLACEMENT?

Challenging Reconstructions Require Specific Surgical Expertise

The complexity of revision surgery is highly variable — and I am always transparent with patients about this before we proceed.

A straightforward loosening case in a patient with good bone stock and no infection can be a relatively contained revision — replacing the worn components with new ones of appropriate size. Challenging but manageable.

An infected implant case is a completely different proposition. It may require two separate surgical procedures separated by weeks of antibiotic treatment. The bone may be damaged by infection, the soft tissues may be compromised, and specialised implants — often with stems that extend further into the bone for better fixation — may be required. Operating time is significantly longer, and recovery is more prolonged.

This is why the surgeon performing revision knee replacement must have specific experience in this type of surgery — it is not an extension of primary replacement. It is a different operation requiring different skills, different implants, and a different approach to planning.

What Revision Knee Replacement Involves

Phase 1

Removal of the Failed Implant

Careful explantation of failed primary components to preserve as much healthy bone as possible.

Phase 2

Assessment & Bone Preparation

Measuring bone defects. Addressing bone loss using bone grafts, metal augments, or specialized sleeves.

Phase 3

Specialised Revision Implants

Inserting revision implants with longer stems and higher constraint to achieve stable fixation in compromised bone.

Phase 4

Rehabilitation (Prolonged)

Carefully paced physiotherapy recovery, tailored to the extent of bone and soft tissue reconstruction.

Revision Knee Surgery Cost Punjab

Revision knee replacement is more expensive than primary replacement — reflecting the greater complexity, longer operating time, and more specialised implants required.

Estimated Cost: ₹5–7 Lakhs This includes specialized implants, longer OT time, and multi-disciplinary care. Two-stage revisions for infection typically fall at the higher end of this range.

* Every patient is assessed individually, and a specific cost estimate is provided after the initial consultation and imaging review.

Second Opinion Before Revision Surgery

If you have been told you need revision knee replacement — by any surgeon, anywhere — I strongly encourage a second opinion before proceeding. Revision surgery is a major undertaking, and the decision should be made with complete confidence.

At NHS Hospital Jalandhar, I offer dedicated second opinion consultations. We analyze the root cause of your joint issue before proposing any intervention.

What to bring: Bring all available X-rays, MRI scans, operation notes from the original surgery, and any recent lab results.

FREQUENTLY ASKED QUESTIONS

Common Questions Regarding Revision Knee Surgery

What is revision knee replacement?

Revision knee replacement is a surgical procedure to replace or reconstruct a previously failed primary knee replacement. It is a highly complex reconstructive procedure performed when primary implants loosen, become infected, or otherwise fail to function correctly.

Why do knee replacements fail?

The two most common causes of failure are aseptic loosening (where the bond between the implant and the bone weakens over time without infection) and deep periprosthetic joint infection (infection around the implant).

How complex is revision knee replacement surgery?

Complexity ranges from a straightforward component exchange in aseptic loosening cases to highly complex two-stage procedures for deep infections. Infection revisions require removing the infected implant, placing an antibiotic spacer, and later inserting a new revision implant.

What is the cost of revision knee replacement at NHS Jalandhar?

Revision knee replacement is priced at approximately ₹5–7 lakhs, depending on the complexity of the reconstruction and the specialized implants required. Infection cases needing two-stage revision fall at the higher end.

Should I seek a second opinion before revision surgery?

Yes, seeking a second opinion is strongly encouraged because revision surgery is a major undertaking. Dr. Shubhang Aggarwal offers dedicated second opinion consultations for patients advised revision knee replacement.

Revision Knee Replacement — When a Previous Surgery Needs to be Redone

Revision knee replacement is the surgical procedure to replace or reconstruct a knee replacement that has failed. It is one of the most complex operations in orthopaedic surgery — more demanding than the original replacement in almost every respect. Get an honest second opinion at NHS Jalandhar.
