Fig. 3From: Impact of five different medial patellofemoral ligament-reconstruction strategies and three different graft pre-tensioning states on the mean patellofemoral contact pressure: a biomechanical study on human cadaver kneesA: Representative X-ray indicating the Schoettle-Point (Schottle et al. 2007); Pa: Anatomical double-bundle MPFL reconstruction using the anatomical, Schoettle-Point and both the proximal and distal patellar fixation points; Pp: Non-anatomical single-bundle MPFL reconstruction using the anatomical, Schoettle-Point and the proximal patellar fixation point; Pd: Non-anatomical single-bundle MPFL reconstruction using the anatomical, Schoettle-Point and the distal patellar fixation point; Fp: Non-anatomical double-bundle MPFL reconstruction using a insertion 1Â cm proximal to the Schoettle-Point and both the proximal and distal patellar fixation points; Fv: Non-anatomical double-bundle MPFL reconstruction using a insertion 1Â cm ventral to the Schoettle-Point and both the proximal and distal patellar fixation points. The yellow dotted lines indicate the reconstruction lines for the Schoettle-PointBack to article page
