| Popis: |
Tibial tubercle osteotomies (TTOs) are procedures designed to address patellofemoral (PF) joint disorders including malalignment, instability, and articular cartilage lesions or arthritis through distal realignment of the extensor mechanism. These osteotomies are generally performed to correct excessive lateralization (external rotation) of the tibial tubercle and/or unload portions of the PF joint. Multiple osteotomy techniques have been described, including the Elmslie–Trillat [1] procedure for direct medialization, Maquet procedure for direct anteriorization [2], and the Fulkerson procedure for anteromedialization (AMZ) [3]. The tibial tubercle can also be moved proximally or distally to correct patella infera or patella alta, respectively. |
