Treatment of patellar dislocation at terminal knee extension
2018
Purpose
Evaluate efficacy of the technique offered for the treatment of patellar dislocation at terminal knee extension.
Material and methods
The review included 67 patients (84 knee joints) with patellar dislocation at terminal knee extension. Surgical planning with the use of Ilizarov module was based on radiological assessment, CT scans and patients’ age. Outcomes of surgical treatment of patients with patellar dislocation at terminal knee extension were followed from 1 to 13 years.
Results
Evaluation criteria of efficient treatment included absence of patellar dislocation, improved knee function and supportability of the limb, relief of knee pain, and the patella being fully engaged with the femoral trochlea on radiographs and CT scans of the knee joint.
Conclusion
The approach to the treatment of patellar dislocation at terminal knee extension facilitated excellent and good results in 97.6 % of the cases. Reoperation was required for two patients to ensure good outcome. Preoperative calculations and accurate technical performance are important for patellar tendon transfer to avoid adverse effects.
