Summary
Dynamic medial patellofemoral ligament (MPFL) reconstruction effectively restores patellar stability. While complication rates are higher than static methods, this technique offers a reproducible and efficient solution for recurrent patellar dislocations.
Area of Science:
- Orthopedic surgery
- Sports medicine
- Biomechanics
Background:
- Medial patellofemoral ligament (MPFL) reconstruction is a standard procedure for managing patellar instability.
- Recurrent lateral patellar dislocation necessitates surgical intervention to restore stability.
- Dynamic MPFL reconstruction offers an alternative surgical technique.
Purpose of the Study:
- To evaluate the outcomes of a dynamic MPFL reconstruction technique.
- To assess the efficacy of this method in a large university hospital setting.
- To analyze patient-reported outcomes and complication rates.
Main Methods:
- A cohort of 213 patients (221 knees) with recurrent lateral patellar dislocation underwent dynamic MPFL reconstruction.
- The procedure involved gracilis tendon transfer with patellar fixation via an oblique transpatellar tunnel.
- Follow-up included Kujala and BANFF scores, pain assessment, and evaluation of recurrent instability over a minimum of 2 years.
Main Results:
- 158 patients (71%) were followed up for a mean of 5.4 years.
- Positive outcomes included a mean VAS pain score of 1.9, Kujala score of 78.4, and BANFF score of 62.4.
- Higher surgeon experience correlated with shorter surgical times. Male patients reported greater satisfaction. Complications occurred in 27.2%, with 9.5% related to recurrent instability.
Conclusions:
- Dynamic MPFL reconstruction is a reproducible technique for restoring patellar stability.
- It demonstrates efficiency in a large-scale setting without requiring intraoperative fluoroscopy.
- Although complication rates are higher compared to static reconstructions, patient satisfaction remains significant, with 78% willing to undergo the procedure again.
