Different Modalities in Management of Recurrent Patellar Dislocation

Abstract

Background Patellar instability is a complex pathoanatomical phenomenon that requires an intricate understanding in order to properly treat patients. Often, the etiology of this entity is multifactorial, and can be the result of a combination of coronal limb malalignment, patella alta, malrotation secondary to internal femoral or external tibial torsion, a dysplastic trochlea, or disrupted and weakened medial soft tissue, including the medial patellofemoral ligament (MPFL) and the vastus medialis obliquus. Objective To review the currently available different modalities for management of recurrent patellar dislocation. This Review will analyze results concerned with Patellar instability to reach the most efficient modality that gives the best results. Material and Methods This systematic review study based on inclusion and exclusion criteria conducted to evaluate the outcome of different techniques of medial patellofemoral ligament reconstruction analyzing their efficacy and possible complications. This systematic review demonstrates that MPFL surgery for recurrent patellar dislocation isolated or in combination with other procedures results in a significant improvement in Kujala scores, a low redislocation rate, and an acceptable complication rate. Despite this, there is no consensus on indications for MPFL reconstruction, graft type, surgical technique, and rehabilitation program. The inclusion criteria for future studies were highly important, and consensus agreement within an expert panel should be sought prior to undertaking such a study. Data Sources Medline databases (PubMed, Medscape, ScienceDirect. EMF-Portal) and all materials available in the Internet till 2021. Data Extraction If the studies did not fulfill the inclusion criteria, they were excluded. Study quality assessment included whether ethical approval was gained, eligibility criteria specified, appropriate controls, and adequate information and defined assessment measures. Results Several fixation methods have been introduced in medial patellofemoral ligament (MPFL) reconstruction. However, the optimal management of patients with recurrent patellar dislocation remains controversial. This short-term study showed that after MPFL reconstruction (suture anchors or transosseous sutures), patellar stability could be restored. And no significant differences in outcome scores were observed between patients in the transosseous suture and suture anchor groups. Conclusion Evaluate the outcome of different techniques of medial patellofemoral ligament reconstruction analyzing their efficacy and possible complications.
