Who is HTO for?

Patient groups that may benefit

Bow legs with wear on the inner side

Medial knee osteoarthritis with bow legs, when the wear is limited mainly to the inner side of the knee. Often active people who want to keep their own knee.

After loss of the inner meniscus

Without the cushioning meniscus, bow legs concentrate the load on the unprotected cartilage.

After a fracture or injury

When a bone has healed in a bowed position and now overloads the knee.

Together with cartilage or meniscus treatment

To take load off a repaired area so that it can heal and last.

Bow legs with loose ligaments

Sometimes combined with a ligament reconstruction to make the knee more stable.

Bowing since childhood

For example after Blount disease or rickets, in adolescents at the end of growth and in adults.

What usually speaks for an HTO

• The bowing lies mainly in the upper shinbone (tibia).
• The wear is limited mainly to the inner side of the knee.
• The outer side of the knee and the kneecap joint are in good condition.
• The knee moves well and is stable, or stability can be restored.
• You are motivated for rehabilitation and want to stay active.

When other options may fit better

When the wear affects the whole knee, when the knee is very stiff or with an inflammatory joint disease, a partial or total knee replacement or another treatment may be more suitable. General health, smoking and body weight also influence bone healing and are part of the assessment.

Where UniPlasty fits in

UniPlasty is a gradual opening-wedge HTO. Whether a gradual correction with a temporary external fixator or a single-step correction with a plate suits you is decided by your surgeon after the assessment.
