Tibiale laterale Open-wedge-Osteotomie bei posttraumatischer Deformität

Objective

Correction of pseudoinstability and tibial malalignment by re-establishment of the pretraumatic tibial axis.

Indications

Posttraumatic valgus malalignment accompanied by pseudoinstability.

Contraindications

Infections, significant inhibition of movement and multidirectional ligament instability.

Surgical technique

Standard anterolateral approach to the proximal tibial head. Lateral open wedge high tibial osteotomy above (supra) the tibiofibular joint and opening until the pseudoinstability of the lateral collateral ligament is levelled.

Postoperative management

Partial weight bearing for 4 weeks, after radiological control full body weight loading is allowed. Implant removal after full bony consolidation.

Results

There is limited evidence in the current literature but the available results show good results in 70% of the cases in long-term follow-up.
