Summary

This study follows 118 people who already received a LEGION knee implant during total knee replacement surgery. Researchers will check how well the implants hold up over 10 years by measuring implant survival and patient quality of life using questionnaires. The goal is to confirm the long-term safety and performance of these devices.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: LEGION porous HA tibial baseplate and/or CR femoral component (knee implant device)
What this could lead to: If successful, this study could confirm that these knee implants are safe and work well for many years after surgery.
What could go wrong: This is an observational follow-up study, not a test of a new treatment. Results may not apply to all patients, and some implants may fail over time.
