Summary

This study addresses questions about four developments in knee replacement surgery:
• Is a metal backing plate for the tibial component of the total knee replacement better than a single high density polyethylene component?
• Is it better to resurface the patella as part of a knee replacement or not?
• Does a polyethylene moving component (bearing) between the tibia and femur have a better outcome than standard designs without a moving bearing?
• Is it better to replace a single component of the knee or to replace the whole knee joint?

The assessment of outcome for each of the comparisons is based on:
• Patient-assessed function and health status
• Reoperation rates
• The 'worth' of any additional cost to the NHS
