Product Description
The specialized contour is designed to precisely buttress the large medial osteotomy gap, distributing stresses effectively while providing a low-profile interface under the pes anserinus tendons.
The proximal head uses large 5.0mm locking screws, creating a strong fixed-angle construct that rigidly resists the high compressive forces across the knee, preventing the opening wedge from collapsing (loss of correction).
The plate acts as a tension band, holding the correction angle stable. The locking technology ensures that stability is achieved independently of the bone graft or bone quality.
Shaft holes accommodate both 5.0mm locking screws and standard 4.5mm cortical screws, allowing the surgeon flexibility in fixing the shaft, including achieving initial compression.
Primary indication for opening wedge osteotomy to correct varus malalignment associated with medial compartment osteoarthritis of the knee.
Used to stabilize the corrective osteotomy required to fix rotational or angular deformities in the proximal tibia.
Indicated where the osteotomy gap requires bone graft or substitutes, providing mechanical stability while the graft incorporates.

This is a specialized titanium plate used in a surgery called High Tibial Osteotomy (HTO), a procedure to treat bow-legged (varus) knees affected by medial compartment arthritis. The surgeon cuts the tibia just below the knee, opens a wedge on the medial (inner) side, and uses this plate to hold the wedge open at the precise correction angle. The plate uses large 5.0mm locking screws to create a rigid internal buttress, ensuring the correction is maintained against the patient's body weight.
Its primary application is to stabilize the corrective osteotomy. Unlike trauma plates used for broken bones, the osteotomy plate must withstand prolonged cyclical loading (walking) while the bone heals across the gap. The plate's fixed-angle strength is non-negotiable for preventing the loss of the carefully planned limb alignment correction.
The major advantage is the stability against collapse. Without rigid fixation, the wedge opening can collapse, losing the correction and compromising the surgical outcome. The 5.0mm locking screws ensure the plate acts as a fixed-angle device, preventing varus collapse and allowing the surgeon to implement early, functional rehabilitation protocols.
Biomechanically, the plate converts the high compressive forces of the knee joint into tensile forces acting on the plate itself. The plate works as a stable buttress that holds the gap open. The fixed angle of the 5.0mm locking screws makes the entire construct exceptionally rigid, enabling the bone to heal with the correct mechanical axis.
After the osteotomy cut is made and the wedge is opened to the predetermined angle, the plate is positioned on the medial side. The surgeon uses K-wires for temporary fixation. The first screws inserted are often the 4.5mm cortical screws for initial positioning, followed by the insertion of the powerful 5.0mm locking screws into the proximal and distal segments to secure the final correction.
The stability of the locking plate construct allows for early initiation of range of motion and weight-bearing (usually partial weight-bearing immediately). Early mobilization is vital for knee health and successful bone healing across the osteotomy gap.
The Proximal Medial Tibial Osteotomy Locking Plate with its 5.0mm screw capacity is a specialized, high-rigidity implant that is indispensable for successful High Tibial Osteotomy. It provides the necessary mechanical stability to maintain precise limb alignment, ensuring effective offloading of the medial compartment and improving patient function.
The proximal tibia bears the full weight of the body. The large 5.0mm locking screws provide much greater purchase and resistance to pull-out and bending, which is necessary to maintain the HTO correction angle under high, prolonged loads.
The plate can be left permanently, but because it is used in younger, active patients and is located subcutaneously, it is often removed approximately 12–18 months after surgery once the osteotomy gap has completely healed and consolidated.
While similar in shape, the Osteotomy Plate is thicker, stronger, and specifically contoured to act as a buttress against the high tensile forces of the opened wedge. It is designed for planned, non-acute stability, not necessarily fracture compression.
Varus deformity, or "bow-leggedness," is a condition where the mechanical axis of the leg shifts inward, concentrating excessive stress and wear on the medial (inner) compartment of the knee, leading to arthritis.
No, this plate is specifically designed for opening wedge osteotomies. Closing wedge osteotomies typically require different fixation methods, such as external fixation or staples, as there is no gap to buttress.
