Indication criterium for a tibial tuberosity transfer is patellar instability with #patella alta (Caton Index higher than 1.3) and/or lateral patella maltrac...
13 kwi 2020 · This video demonstrates the surgical management of patellofemoral instability and a trochlear chondral defect via tibial tubercle osteotomy, medial patellofemoral ligament reconstruction, and a cryopreserved osteochondral allograft.
A tibial tubercle transfer is a procedure in which the tibial tubercle, a small bony prominence below the kneecap, is moved to a new position. This helps to realign the patella and improve joint function. The procedure is typically performed through an incision on the front of the knee.
Video 1. Technique for measured tibial tuberosity distalization and medial patellofemoral ligament reconstruction. The video describes how the 2 procedures may be combined, including dual access to the tuberosity and hamstrings through 1 incision.
Tibial tubercle transfer technique involves realignment of the tibial tubercle (a bump in the front of the shin bone) such that the knee cap (patella) traverses in the center of the femoral groove. The patellar maltracking is corrected by moving the tibial tubercle medially, towards the inside portion of the leg.
In the case of recurrent patella dislocations exacerbated by an abnormally lateral and/or higher position of the anterior tibial tuberosity, the ATT can be repositioned to stabilise the patella. An ATT requires an operation planned during pre-surgery consultations based on knee x-rays and a CT scan.
The decision on tibial tuberosity transfer is made for PF pain/instability after. Clinical examination; Imaging measurement of TT-TG distance and patella height; Arthroscopic assessment of the pattern of articular cartilage damage
