This Mayo Clinic case series reviews outcomes of cemented condylar TKA in patients with a prior tibial plateau fracture. It asks whether these post-traumatic knees achieve durable pain relief and function, and how their complication burden compares with routine primary TKA.
When a patient with a healed tibial plateau fracture presents with end-stage arthritis, TKA works, but counsel them that this is not a routine replacement. Expect a reoperation rate near 21% and a postoperative complication rate around 26%. The dominant problems are soft-tissue healing, stiffness, and intraoperative extensor mechanism disruption, not implant loosening.
The decisive lesson: every patient who had alignment restored and components positioned ideally had no pain, no revision, and no loosening. Suboptimal position or residual deformity tracked with poorer outcomes.
Plan these cases like complex revisions. Rule out occult infection with serology, bone scan, and aspiration. Anticipate the need for long-stem components, defect augmentation, hardware removal, and extensile exposure such as the quadriceps snip.
Useful mental model: the original fracture treatment (ORIF vs nonoperative) does not predict difficulty. The residual deformity and soft-tissue scarring do.
