Treatments

Revision joint replacement surgery is a specialized procedure performed to replace or repair a previous hip, knee, or shoulder implant that has failed, worn out, or caused complications. Unlike primary joint replacement, revision surgeries are more complex because they deal with scar tissue, bone loss, or implant loosening. These procedures aim to restore function, relieve pain, and improve the longevity of the joint.

Indications for Revision Surgery

• Implant Loosening – The original prosthesis becomes unstable over time.
• Wear and Tear – Natural wear of joint components leading to pain and restricted movement.
• Infection – Deep infection around the joint requiring removal and replacement of the implant.
• Fractures Around Implant – Bone fractures affecting the stability of the prosthesis.
• Instability or Dislocation – The joint becomes unstable or dislocates frequently.
• Pain or Functional Loss – Persistent pain or limited mobility despite initial replacement.
• Allergic Reactions – Rare reactions to implant materials necessitating replacement.

Types of Revision Surgeries

• Revision Total Hip Replacement – Replacing a failed hip prosthesis with a new implant.
• Revision Total Knee Replacement – Correcting or replacing a previously implanted knee prosthesis.
• Revision Shoulder Replacement – Replacing or repairing a previous shoulder implant.
• Complex or Multi-stage Revision – Sometimes performed in cases of severe infection or major bone loss.

Surgical Procedure

• Preoperative Planning: Detailed imaging (X-rays, CT scans) to assess bone and implant condition.
• Anesthesia: General or spinal anesthesia.
• Incision and Exposure: Accessing the previous joint while managing scar tissue.
• Removal of Old Implant: Carefully extracting the old prosthesis and any cement.
• Bone Preparation: Restoring bone stock using grafts if needed.
• Implantation of New Prosthesis: Using modern implants, sometimes customized for complex cases.
• Closure and Stabilization: Muscles and skin are sutured, and the joint is stabilized.
