Background:
Great difficulty and more failures were the descriptions of the treatment of congenital patella dislocation in pediatric patients. This study aims to evaluate the outcomes of patients with congenital patellar dislocations treated with the modified Langenskiöld procedure.
Methods:
The medical records of 16 knees in 11 patients with a diagnosis of congenital patella dislocation were collected from September 2016 to March 2019. They were treated with the modified Langenskiöld procedure. The mean follow-up period was 37.8 months. The outcome measures were the Lysholm score, Kujala score, patellar stability, and knee range of motion.
Results:
Eleven patients, namely, eight girls and three boys, with 16 knees were enrolled. The mean age at the time of operation was 3.1 years. The post-operative mean Lysholm score was 94.8 (SD 5.1; 87-100), whereas the Kujala score was 95 (SD 5.9; 86-100). There were no recurrent dislocations, and all patients had full extension postoperatively.
Conclusion:
The modified Langenskiöld procedure is a promising solution for the treatment of congenital patella dislocations.
Level Of Evidence:
Level IV; Case Series; Treatment Study.
