N2  -  Summary. Purpose. The present study aimed to compare medial patellofemoral ligament (MPFL) reconstruction associated with lateral retinacular release (LRR) and conservative treatment for patients with first-time acute patellar dislocation in absence of the underlying anatomical high-risk factors for further patellar dislocations. Methods. We enrolled 39 consecutive patients who were treated with MPFL reconstruction associated with LRR for first-time acute patellar dislocation at our institution from August 2018 and August 2021. To compare the treatment results between the MPFL reconstruction associated with LRR and conservative treatment, a consecutive series of 84 first-time acute patellar dislocation patients with conservative treatment without underlying anatomical high-risk factors were included as a control group, and demographics and clinical characteristics of patients in different groups were compared. Results. Notably, nearly all postoperative complications occurred in the control group, and no recurrent instability was found in the MPFL group, compared with 11.9% in the control group (p<0.05). All the patients had functional outcome scores available at a mean of 23.7 ±5.7 months, and there was a statistically significant improvement in the international knee documentation committee (IKDC) score, Lvsholm score and visual analogue scale (VAS) score at the final follow-up (p<0.001, respectively). Furthermore, the IKDC score, Lvsholm score and VAS score were significantly improved in the MPFL group patients than those in the controls group patients (p<0.05, respectively). Conclusions. Based on the available evidence, the surgical MPFL reconstruction associated with LRR of first-time acute patella dislocation in absence of the underlying anatomical high-risk factors are associated with better clinical outcomes and a lower risk of recurrent dislocation compared with non-surgical treatment. Surgery should be considered as the better choice for these specific patients.
