Objectives: Paediatric patellofemoral instability (PFI) is a wide spectrum of disorder from mild anterior knee pain to patellar dislocation with degenerative arthritis. Many anatomic and biomechanical factors contribute for this and assessing and addressing each factor is a himalayan task and gives suboptimal results. In this procedure we can address all the etiological factors and approach in a a la cart manner with excellent results and no relapse at all.

Materials and Methods: It’s a retrospective study done between 2019 and 2024 in a rural hospital, 12 knees (9 female and 3 male, 8 right and 4 left). All were having trochlear dysplasia with various degrees with ligamentous laxity in 5 cases.4 steps are 1) Q tube plasty 2) Lateral sagittal z plasty 3) Lateral hemi transfer of patellar tendon 4) Tenodesis with semitendinosus.

Pre and post of evaluation done with kujala scoring and radiological assessment.

Discussion and Conclusion: Many bony and soft tissue factors contribute for the patellar dislocation. To avoid relapse and obtain excellent results, all the etiological factors need to be addressed especially in children as early as possible. Though many stabilization procedures are tried like MPFL reconstruction, it has its own drawbacks like stiffness, physeal damage with suboptimal results and high unsatisfactory results from 20 to 80%. In our technique relapse rate was nil and excellent outcome and high satisfactory results from children and parents with many advantages like no implants, no radiation hazards and near normal range of motion.
