Key Points

To compare the biomechanical outcomes, specifically patellar stability, lateralization, and contact pressures, across three surgical techniques for medial patellofemoral complex reconstruction.
Biomechanical comparison of three distinct surgical reconstruction techniques targeting the medial patellofemoral complex.
Measurement of patellar lateralization, medial constraint, and patellofemoral articular contact pressures.
All three surgical techniques restored patellar stability with no significant differences in patella lateralization.
Reconstructions resulted in medial overconstraint but preserved comparable patellofemoral articular contact pressures across techniques.
