Do Patient Specific Implants Improve Accuracy of Correction With MOWHTO. A Pilot Study for a Definitive Randomised Trial Comparing TOMOFIX and BodyCAD Fine Osteotomy.
Do Patient Specific Implants Improve Accuracy of Correction With MOWHTO. A Pilot Study for a Definitive Randomised Trial Comparing TOMOFIX and BodyCAD Fine Osteotomy.
This is a single centre, randomised, patient blinded pilot study that will assign 40 participants with medial knee osteoarthritis undergoing medial opening wedge high tibial osteotomy (MOWHTO) to either current standard of care with TOMOFIX plating system, or utilise patient specific instrumentation and custom-made plate development, with BodyCAD Fine Osteotomy. If the definitive study is deemed feasible, an additional 110 participants will be randomized, for a total of 150 participants.
The proposed study is a single centre, pilot randomised controlled, patient blinded study that will randomly assign 40 participants with medial knee osteoarthritis undergoing medial opening wedge proximal tibial osteotomy (MOWHTO) to either current standard of care, with TOMOFIX plating system, or utilise patient specific instrumentation and custom-made plate development, with BodyCAD Fine Osteotomy. Participants will follow a standardized rehabilitation protocol. Outcomes will be assessed over two years postoperatively utilising CT assessment for accuracy of correction, bony union and construct stability as well as PROMs including KOOS and EQ5D.
Complications, adverse events, returns to theatre and costs will also be recorded. End of study is defined when the last enrolled subject reaches the 24-month follow-up time point and close-out activities are complete.
If the pilot study demonstrates the feasibility of the definitive trial, an additional 110 participants will be ennrolled, for a total of 150 participants.
