Medial Opening Wedge Proximal Tibial Osteotomy.

Area of Science:

• Orthopedic surgery
• Biomechanics
• Knee joint anatomy

Background:

• Genu varus malalignment can cause medial compartment overload, accelerating knee osteoarthritis.
• Proximal tibial osteotomy (PTO) is a surgical option to correct this alignment.

Purpose of the Study:

• To describe the surgical technique for a medial opening wedge proximal tibial osteotomy (PTO).

Main Methods:

• The procedure involves a medial opening wedge osteotomy of the proximal tibia.
• It can be performed in isolation or combined with ligamentous reconstruction.
• Correction of sagittal and coronal plane deformities is possible.

Main Results:

• This technique aims to reduce stress on the medial compartment of the knee.
• It can prevent graft failure in concurrent ligament reconstructions.
• The procedure is indicated for genu varus with medial compartment osteoarthritis.

Conclusions:

• Medial opening wedge PTO is an effective technique for correcting genu varus malalignment.
• It plays a vital role in managing knee osteoarthritis and improving outcomes of ligamentous reconstruction.
