Biomechanical Analysis of Tibial Tuberosity Medialization and Medial Patellofemoral Ligament Reconstruction.

摘要: Biomechanical studies are commonly performed to evaluate the influence of medial patellofemoral ligament (MPFL) reconstruction and tibial tuberosity medialization on patellar tracking contact pressures. The most common method is in vitro simulation knee function, but computational function vivo motion can also be utilized. current review biomechanical literature indicates that MPFL reduce lateral tracking. Decreased pressures have been noted. For reconstruction, noted concerns graft overtensioning nonanatomic attachment femur leading overconstraint patella elevated medialization, altered tibiofemoral kinematics postoperative unknown. Future should emphasize inclusion anatomic features patterns related instability, with comparison between surgical approaches for continued development treatment guidelines.
