Complications of Knee Revision

Complications of Knee Revision


Despite the long-term clinical success of total knee arthroplasty with reported survivorship of greater than 95 % at 15 years and improvements in implant design, as small percentage of patients will experience clinical failure presenting with pain and impaired function. The revision rate has been established to be less than 3% within the first two years of index arthroplasty. A systematic approach to patient requiring revision knee surgery can optimize the chance of a successful outcome. The etiologies of dysfunction and pain after total knee replacement can be numerous and are usually grouped into two large categories:

  • Extrinsic (extra-articular)

    • Hip Pathology
    • Lumber Spine
      • Stenosis
      • Radiculopathy
    • Neuroma
    • Complex regional pain syndrome
    • Vascular Claudication
    • Soft tissue inflammation
      • Pes Bursitis
      • Patellar tendonitis
      • Quadriceps Tendinitis
    • Periprosthetic Fractures
      • Tibial Stress Fractures
      • Patellar Stress Factures
  • Intrinsic (intra-articular)

    • Infection
    • Instability
      • Axial
      • Flexion
      • Global
    • Malalignment
      • Axial
      • Flexion
      • Global
    • Aseptic loosening
    • Polyethylene wear
    • Osteolysis
    • Arthrofibrosis
    • Soft Tissue Impingement
    • Patellar Clunk
    • Popliteus Tendon Impingement
    • Component overhang / Excess cement
    • Extensor Mechanism Dysfunction
      • Patellar Instability
      • Patellar Fracture
      • Patellar Pain
        • Unresurfaced Patella
        • Lateral Facet Impingement
        • Excessive Composite Thickness
        • Quad/ Patellar Tendon Rupture
