Technique

1. Median parapatellar incision
- Possible intra-articular exploration by arthroscopy or short arthrotomy.
- Release of medial tibial metaphysis,
- Insertion of a posterior retractor protecting neurovascular tissues and an anterior retractor under the patellar tendon at its insertion on the tibial tuberosity.


2. The trial implant indicates the precise position and direction of the osteotomy :
- Perpendicular to the tibial diaphysis.
- Oblique superiorly and laterally, passing through the superior edge of the tibial tuberosity and directed towards the superior extremity of the heads of the fibula.
- A pin is placed according to these landmarks and its correct position is confirmed on a x-ray.






3. The medial osteotomy is performed by absolutely preserving the lateral aspect.
- The implant, pre-adjusted on the basis of preoperative radiographic calculations, is positioned in the opening.
- Clinical and radiological assessment of the correction obtained.
- The opening can be increased or decreased at any time during the operation by simply removing the plate and reajusting the separation.
- Screwing of the plate.





4. Postoperative course
- No postoperative immobilization.
- Immediate rehabilitation.
