High Tibial Osteotomy
Joint-preserving high tibia osteotomy plays a major role in the treatment of unicompartmental knee arthrosis.
HTO Features
- Simple, image-free registration of the leg alignment
- Dynamic goniometry in frontal and sagital plane
- Control of changes of tibia slope, rotation and leg length
- Optional registration of ligament stability
- Documentation of results
- Modular, calibrated instruments
- Use of state-of-the art passive infrared sensor technology, for simple intraoperative handling
Software Elements
Innovation
OrthoPilot® allows the precise execution of axis-correcting maneuvers in the opening-wedge HTO technique. This is established by continuous monitoring of the leg alignment by means of infrared position tracking. The final HKA angle can be navigated and adjusted by degree with high precision. The passive infrared sensor technology allows for wireless operation without artifacts in intraoperative radiography.
Perfection
The navigational fine-tuning of the leg alignment provides utmost reproducible accuaracy in HTO. The OrthoPilot® HTO procedure is independent from the osteosynthesis implant system being used. The intraoperative, dynamic goniometry of the current leg alignment is displayed, including the actual femorotibial angle for checking the present deformity and its correction. In frontal plane, stability of the collateral ligaments can be assessed through varus and valgus stress.
