Abstract:

Objective To explore the effect of arthroscopic lateral retinaculum release(LRR)combined with medial patellofemoral ligament⁃reconstruction(MPFL⁃R)in the treatment of juvenile recurrent dislocation of patellar(RDP). Methods The clinical data of 56 adolescent RDP patients treated with open medial retinaculum constriction(group A)and 78 adolescent RDP patients treated with arthroscopic LRR combined with MPFL ⁃ R (group B)were analyzed retrospectively. The operative indexes and complications were compared. Results There were fewer intraoperative blood loss and shorter operation time and length of stay in group B(P < 0.05)(P < 0.05). The suitable angles and lateral patellofemoral angles,Lysholm scores and Kujala scores in the two groups were higher than those before treatment(P < 0.05),particularly in group B(P < 0.05). The total incidence of complica⁃ tions in group B was lower than that in group A(P < 0.05). Conclusion Arthroscopic LRR combined with MPFL⁃R for the treatment of RDP in adolescents has good effect and less complications.
