Abstract

Background: Recurrent patellar instability is a difficult condition that frequently necessitates surgical treatment for effective management. Reconstruction of the medial patellofemoral ligament (MPFL) has become the standard surgical approach for restoring patellofemoral stability and enhancing functional results. Introduction In orthopaedic practise, patellar instability, characterised by the displacement of the patella from its normal location inside the patellofemoral joint, is a major problem. After anterior cruciate ligament tears, acute traumatic patellar dislocation is the second most prevalent cause of traumatic hemarthrosis of the knee. Objective: The purpose of this research is to assess the early outcomes of MPFL reconstruction using hamstring autograft using the dual patella docking technique for the treatment of recurrent patellar instability. Conclusions: In the surgical treatment of recurrent patellar instability, MPFL reconstruction with hamstring autograft via the dual patella docking technique shows promise. The use of hamstring autograft provides sufficient strength and anatomical resemblance to the native MPFL while limiting morbidity at the donor location. The twin patella docking approach offers benefits in terms of graft attachment and tensioning, which contribute to superior outcomes.
