Objective:

To report the 5-year results of patients with medial mobile-bearing UKR who developed severe lateral disease and were treated with a Fixed Lateral Oxford (FLO) as a staged bi-UKR procedure, where 'staged bi-UKR' refers to a sequential surgical approach addressing both compartments of the knee.

Key Findings:
  • No intraoperative complications or early mortality were reported.
  • One re-operation occurred due to medial bearing dislocation, successfully treated.
  • Post-operative OKS showed significant improvement at 5 years, with an increase from X to Y (insert specific values).
Interpretation:

The FLO provides a reliable option for patients with lateral compartment osteoarthritis after medial UKR, with favorable clinical outcomes and low complication rates.

Limitations:
  • Retrospective analysis may introduce bias, limiting the strength of causal inferences.
  • Limited sample size may affect generalizability.
Conclusion:

The Fixed Lateral OUKR is a viable treatment option for patients with lateral osteoarthritis following medial UKR, demonstrating promising clinical outcomes over a 5-year period, suggesting its potential as a reliable alternative to TKR.
