Patient Specific Instrumentation in TKR

Status Completed

Clinical Trial Summary

Clinical Trial Description

This is a randomised control trial to assess the benefits of using patient specific instrumentation in total knee replacement surgery. Patient specific instrumentation is an individualised system for total knee replacement surgery. The system has been marketed and is already in use in some centres. The process is similar to traditional knee replacement surgery but approximately 6 weeks prior to the operation patients will undergo an MRI scan of their knee, hip and ankle. From this data the dimensions and rotation of the knee can be accurately measured, and a custom made jig can be made specific to that patients anatomy. The jig is used intra-operatively to make accurate bone cuts according to this pre-operative plan, the type of implant used remains the same but the sizing of the components, and alignment of the implant is expected to improve. This study assesses any improvement in implant alignment in using the patient specific instrumentation, any improved intra-operative outcomes and any long term clinical outcome improvements for patients. ;
