The anterior tibial tubercleplasty, commonly referred to as a Maquet type procedure, is a surgical intervention aimed at addressing patellar instability. This procedure is particularly relevant for patients experiencing issues with the tracking of the patella, which can lead to pain and functional limitations. During the operation, the surgeon makes a precise incision lateral to the patella, extending across the tibial tuberosity and continuing distally along the anterior ridge of the tibia. This approach allows for the elevation of the muscles that cover the anterior compartment, providing access to the underlying structures. The procedure involves careful exposure of the medial and lateral borders of the patellar tendon and the tibial tuberosity, which is crucial for the subsequent steps. The surgeon then makes an incision through the periosteum, located distal to the tuberosity, to facilitate the repositioning of the tibial tuberosity. K-wires are strategically inserted to guide the osteotomy cuts, ensuring that the tibial tuberosity can be accurately repositioned to achieve optimal patellar alignment within the intercondylar groove. The final assessment of patellar tracking is critical, as it determines whether any adjustments are necessary to prevent under- or overcorrection. Once the desired alignment is confirmed, the tibial tuberosity is secured in place using one or more screws, completing the procedure and aiming to restore proper knee function.
