Understanding 'S/P Revision Left TKR': Revision Total Knee Arthroplasty

"S/P revision left TKR" is medical shorthand for:

• S/P = Status Post (after)
• Revision = Reoperation to replace/modify a failed implant
• Left = Left knee
• TKR = Total Knee Replacement (Arthroplasty)

Meaning: The patient has undergone a revision surgery on a previously implanted left total knee prosthesis.

Common Reasons for Revision

• Aseptic loosening (most common)
• Infection (periprosthetic joint infection)
• Instability (ligament insufficiency)
• Malalignment/Component malposition
• Polyethylene wear/osteolysis
• Periprosthetic fracture
• Stiffness/arthrofibrosis

Procedure Scope

May involve exchanging one component (polyethylene insert only) or all components (femoral, tibial, patellar). Complexity increases with bone loss, requiring augments, cones, stems, or allograft.

Recovery

Longer and more demanding than primary TKR: extended protected weight-bearing, slower rehabilitation, higher complication rate. Outcomes generally good but less predictable than primary.
