MD3T

Product catalog summary

Introduction
The Multi-Directional Tibial Tubercle Transfer (MD3T) System is a surgical technique designed to treat patellofemoral disorders by allowing precise and safe tibial tubercle transfers in multiple directions. This system is considered an advancement over the traditional anteromedialization (AMZ) technique.

Historical Context
The practice of medial transfer dates back to 1888, with anterior transfer introduced in 1976. The AMZ technique, combining these transfers, was developed in 1983. The MD3T system builds on these techniques by offering more flexibility and precision.

MD3T Technique

A Primary Wedge of bone containing the Tibial Tubercle and Patellar Tendon is created.
For medialization, a Secondary Wedge is created medial to the Primary Wedge.
The Primary and Secondary Wedges are transposed to achieve medial transfer, with the width of the Secondary Wedge determining the transfer distance.
Bone void filler or grafts are used to fill spaces created by the transfer.
Unidirectional transfers (anterior, distal, proximal) involve repositioning only the Primary Wedge.

Advantages
The MD3T system allows for independent planning of medial and anterior transfer distances, preserves cortical integrity, and reduces the risk of tibial stress fractures.

Multi-Directional Tibial Tubercle Transfer System For Medial, AMZ, Anterior, Distal, and Proximal Transfers Before Transfer After Transfer Faster Recovery A simple set of instruments allows for precise creation of two compound wedges of bone. Transposing these wedges medializes the tubercle. Because of the surgical benefits of the MD3T procedure relative to the AMZ, I have no doubt that this approach will ultimately become the new world standard. The MD3T system will allow the average orthopedic surgeon to safely and reproducibly perform a tubercle transfer. Scott F.

Transferring the tibial tubercle (TT) to treat patellofemoral disorders is a time-tested and well-established surgical technique. Medial transfer has been practiced since 18881, and anterior transfer was introduced by Maquet in 19762. In 1983, Fulkerson combined these two transfers in the antero-medialization (AMZ) technique3. In addition, distal transfer to correct patella alta, and lateral transfer to reconstruct an over-medialized TT, are occasionally indicated. The Multi-Directional Tibial Tubercle Transfer (MD3T) System from Kinamed has unique advantages: it enables the surgeon to move the...
