Revision Joint Replacement – Knee & Hip

What Is Revision Joint Replacement?

A Revision Joint Replacement is a surgical procedure performed to remove and replace a previously implanted artificial joint that has failed or is causing problems.

Why Is Revision Joint Replacement Needed?

You may require a revision hip or knee replacement if you are experiencing:

• Persistent joint pain even months or years after your first surgery
• Loosening of the joint implant
• Implant Dislocation
• Joint stiffness or reduced mobility
• Periprosthetic joint infection (PJI)
• Fractures around the implant(periprosthetic fractures)
• Implant wear and tearafter 10–20 years of use
• Technical failure or implant malpositionin primary surgery

Early detection and timely revision surgery can prevent further damage and help restore your quality of life.

• 1. 3D Robotics & Navigation TechnologyWe use advanced 3D robotic-assisted systems to plan and execute revision procedures with sub-millimetric accuracy, especially when previous implants have altered the anatomy.
• 2. Preoperative Imaging & Bone AssessmentHigh-resolution X-rays, CT scans, and infection markers help us assess implant positioning, bone loss, and soft tissue integrity.
• 3. Specialized Revision ImplantsWe use modular implants, longer stems, sleeves, cones, and constrained designs to restore joint function, even in complex cases with severe bone defects.
• 4. Infection controls
  One-Stage vs Two-Stage Revision for Periprosthetic Joint Infection (PJI)Periprosthetic Joint Infection (PJI) is one of the most serious complications after knee or hip replacement surgery. Managing it requires expert surgical planning and a multidisciplinary approach. At Phoenix Orthopaedic Centre, Dr. Darshan Shah offers both one-stage and two-stage revision surgeries, depending on the infection type, severity, and patient condition.✅ One-Stage Revision SurgeryIn a one-stage revision, the infected implant is removed and a new prosthesis is inserted during the same surgery. The joint is thoroughly cleaned, and targeted antibiotics are administered.When is it preferred?
  • Infection is caused by a known, low-virulence organism
  • Good soft tissue condition and minimal bone loss
  • Patient is immunologically stable and fit for single-stage reconstruction

  Benefits:

  • Only one surgery and hospital admission
  • Faster recovery and reduced treatment time
  • Lower total treatment cost

  ✅ Two-Stage Revision Surgery

  A two-stage revision is the gold standard for treating chronic or complex joint infections. It involves two separate surgeries:

  • First Stage: Removal of the infected implant, aggressive debridement, and placement of an antibiotic-impregnated cement spacer
  • Antibiotic Therapy 2. 6–8 weeks of tailored intravenous antibiotics
  • Second Stage: 3.Once infection markers normalize, a new prosthesis is implanted

  When is it preferred?

  • Infection caused by high-virulence or unknown organisms
  • Presence of sinus tracts, bone defects, or poor soft tissue quality
  • Failed previous infection control attempts

  Benefits:

  • Higher infection eradication rates in chronic or severe cases
  • Custom antibiotic therapy ensures deep infection control
  • Allows better soft tissue healing before final reimplantation

  ✅ Expert Decision-Making for Best Results

  Dr. Darshan Shah personally evaluates each case to determine the most appropriate strategy—one-stage vs two-stage—based on:

  • Microbiological culture reports
  • Blood markers (CRP, ESR, WBC)
  • Imaging (X-rays, MRI, nuclear scans)
  • Overall patient health and surgical history

  Our goal is to eradicate infection, restore function, and prevent recurrence, all while minimizing risks and downtime.:

  Dr Darshan Shah is a pioneer in infection control and eradication in cases of PJI following Knee and Hip Joint Replacement. He has successfully published various techniques for creating mobile spacers for hip and knee replacement infection control.

• 5. Minimally Invasive TechniquesWhere feasible, MIS (Minimally Invasive Surgery) techniques are used to reduce blood loss, pain, and hospital stay.
• 6. Customized Rehabilitation ProgramsPost-surgery, we design tailored physiotherapy and strengthening protocols to maximize range of motion, joint function, and independence.
