Patellar dislocation is a multifactorial disorder with high prevalence in young people and, in most cases, leads to recurrent instability and impairment of function. To restore patellofemoral stability, different combined surgical methods are used, but not much comparative evidence has been done on their results. This is a prospective observational study consisting of fifteen patients with patellar dislocation undergoing a surgical intervention within the period of September 2022 and August 2024. The patients were divided into three categories: the reconstruction of the medial patellofemoral ligament (MPFL) using medial patellar retinaculum (MPR) plication, the lateral patellar retinaculum (LPR) release using MPR plication, and the MPFL reconstruction using the LPR release. Due to functional outcomes, the International Knee Documentation Committee (IKDC) and Lysholm scores were used as evaluation instruments, whereas in radiological results, the congruence angle, patellar tilt angle, lateral patellofemoral angle, and lateral patellofemoral index were taken into account. The outcome of all surgical modalities was a great enhancement of radiological alignment and functional score at the follow-up. Intergroup comparison showed that there were greater IKDC and Lysholm scores of the MPFL reconstruction with the LPR release group in comparison with other groups (p < 0.05). The method of combined surgical stabilisation procedures is effective in the treatment of patellar dislocation, and MPFL reconstruction in association with the lateral patellar retinacular release has better functional results.
