Aberrant anatomy, such as patella alta, can be a risk factor for recurrent patellar instability or inferior clinical outcomes after medial patellofemoral ligament reconstruction. In patients with significant patella alta (Caton Deschamps Index >1.2), tibial tubercle distalization may be considered to improve outcomes. However, despite patellar instability commonly affecting pediatric patients, a distalization osteotomy is not feasible in this patient population due to the presence of open physes. Our article presents a technique describing an alternative soft-tissue distalization approach whereby patellar height is decreased by shortening the patellar tendon.
异常解剖结构，如高位髌骨，可能是髌骨复发性不稳定或髌股内侧韧带重建术后临床效果不佳的危险因素。对于高位髌骨明显（Caton Deschamps指数>1.2）的患者，可考虑进行胫骨结节远端化以改善预后。然而，尽管髌骨不稳定常见于儿科患者，但由于存在开放骨骺，这种患者群体无法进行远端化截骨术。我们的文章介绍了一种技术，描述了一种替代性的软组织远端化方法，即通过缩短髌腱来降低髌骨高度。
