Medial knee arthrosis degenerates faster if articular damage is associated with tibial varum and lateral ligament insufficiency. In such cases, a metaphyseal realignment through tibial osteotomy can relieve pain and reduce effusion. If performed in an early stage of deterioration, the surgery will greatly reduce the inevitable course of osteoarthritis and improve patient quality of life.
The dedicated PTA external fixation system is used for the correction of tibial varus through gradual distraction.
Using the PTA, surgery is simple, quick, and non-invasive with minimal rehab postop and rare but easily manageable complications.
