Study of patellar kinematics after reconstruction of the medial patellofemoral ligament

Does Medial Patellofemoral Ligament Reconstruction Decrease Patellar Height? A Preliminary Report

“…4,22 It has been found that patella alta results in 19% less contact area and consequently greater patellofemoral stress over the range of 0 to 60 degrees of flexion. 26 Beyond 30 degrees of flexion, the patellar stability depends on the osseous restraints provided by the trochlear groove, and thus the importance of soft-tissue restraints decreases. 3,7,24,25 It has been suggested that this technique would decrease the degree of knee flexion required for patellar engagement in the trochlea.…”

Results of anatomic gracilis MPFL reconstruction with precise tensioning

“…In a recent cadaveric study, Philippot et al [21] confirmed that the ideal graft tension is 10 N. This tension can significantly reduce the tilt angle and avoid hyper-correction. Thaunat and Erasmus [31] reported two cases of excessive tension applied to the graft and having required percutaneous surgical section.…”

“…Optimal graft tensioning is the most critical step in MPFL reconstruction as reported in the literature. In a recent cadaveric study, Philippot et al [21] confirmed that 10 N of graft tension was considered optimal. This tension can significantly reduce patellar tilt and prevent hypercorrection and overconstrained graft on the medial patellofemoral compartment.…”

Reconstruction du ligament patello-fémoral médial : résultats cliniques et radiographiques sur une série de 90 ligamentoplasties

“…Ces études, fondées sur des petites séries, ont rapporté de bons résultats cliniques, notamment à court terme. Aucune technique n'étant supérieure aux autres, de plus grandes séries au recul plus long étaient nécessaires [4][5][6] des impératifs anatomiques et biomécaniques résultants d'études cadavériques réalisées au préalable [7].…”
