| 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 |
 |
No
postoperative immobilization.
Immediate
rehabilitation. |
