Clinical Trial Summary

A study to compare the accuracy of achieving the planned correction between personalised (TOKA) high tibial osteotomy (HTO) procedure and standard generic HTO procedure.


Clinical Trial Description

The trial design is a multi-centre, blinded, superiority two arm, parallel group design randomised controlled trial (RCT) of personalised (TOKA) versus standard high tibial osteotomy (HTO). The aim of the PASHiOn trial is to establish whether digitally planned personalised HTO surgery (TOKA) increases the accuracy of bone correction in comparison to conventional HTO surgery. Embedded within the trial is a non-randomised pre-RCT technology check and safety assessment of 5 patients (Phase 1), followed by a randomised controlled trial of 88 patients (Phase 2). During phase 1 of the clinical investigation, 5 patients fulfilling the inclusion criteria will be recruited and assessed in an identical way to the 88 patients recruited in the main trial, but without randomisation. Recruitment of the remaining patients (Phase 2) will take place after the six-week assessment on the fifth patient is complete and the oversight committee supports progression to Phase 2. Patients will be randomised to Phase 2 in a 1:1 ratio and patients will be blinded as to which treatment arm they receive. ;
