Revision Joint Replacement

---

Revision Joint Replacement refers to a second surgery performed to replace one or more components of a previously implanted total knee or total hip replacement. These procedures are significantly more complex than primary joint replacement surgeries and have evolved into a specialized subspecialty within orthopaedics. Revision surgeries may range from replacing a single worn-out component to removing and reconstructing the entire joint with specialized implants.

Revision joint replacement is usually required when the original implant loosens, wears out, or fails. Common reasons include implant aging (often after 10–20 years), recurrent dislocation, infection, fracture around the implant, ligament instability, leg length discrepancy, or persistent pain. In some cases, a combination of implant wear and poor soft tissue support may require the use of custom-made or highly constrained prostheses.

Due to the technical difficulty involved, these surgeries are best performed by experienced joint replacement surgeons with specific expertise in revision procedures. General orthopaedic surgeons often refer such cases to specialists trained in complex hip and knee reconstructions.

Surgical Complexity and Hospital Care

Revision joint replacement may involve:

• Removal of the old prosthesis and bone cement
• Clearing of scar tissue and dead bone
• Reconstruction of bone loss using bone grafts from a bone bank
• Use of custom-designed implants when standard prostheses are not suitable

Hospital stay is often longer than for primary joint replacement, depending on the extent of bone damage and surgical complexity. Postoperative rehabilitation usually includes physiotherapy, occupational therapy, and home-based care, similar to primary replacement but often more prolonged.

Risks and Outcomes

Revision joint replacement carries higher risks than first-time surgery due to weaker bone quality and scar tissue. While primary joint replacement has a success rate of about 95%, revision surgery typically has a success rate of around 85%.

Possible complications include:

• Infection (2–4%)
• Loosening of the new implant (10–15%)
• Bone fractures during or after surgery
• Dislocation (twice as common as primary surgery)
• Leg length discrepancy
• Bone loss around the joint

Patient Perspective and Importance of Expertise

Patients undergoing revision surgery often approach treatment with greater awareness and caution than first-time patients. Many actively research surgeons and institutions, and are willing to travel long distances to find a highly experienced revision joint replacement team. While the risks are higher, a large number of patients achieve excellent pain relief and functional improvement when surgery is performed by skilled specialists.

With meticulous planning, advanced implants, and expert surgical care, revision joint replacement can successfully restore mobility, stability, and quality of life even after a failed joint replacement.
