“…As conservative treatment of habitual patellar dislocation in young children is ineffective [21], the only possible treatment is surgical correction. However, the typical surgical methods used in adults are unfavorable in children, as they possess far more risks such as possible growth plate arrest and progressive genu recurvatum.…”

“…The treatment of habitual patellar dislocation in children is a complicated issue. The underlying anatomical pathology is complex and treatment should address patellar realignment, as well as extensors biomechanics [ 2 , 9 , 12 , 21 , 23 ]. In the pediatric population, this condition should be treated early, because it may progress to patellofemoral joint deformation, permanent pain, and osteoarthritis [ 23 ].…”

Purpose In this study, the functional mid-term outcomes of the modified Grammont and Langenskiöld technique was assessed in skeletally immature patients with habitual patellar dislocation, with emphasis on knee function, pain, and other possible post-surgical complications. This is the first study concerning the application of the modified Grammont and Langenskiöld technique in habitual patellar dislocations. Methods This retrospective cohort study considered 10 patients (15 knees), ranging from 7 to 11 years old, who underwent the modified Grammont and Langenskiold procedure between 2015 and 2018. History of dislocation, patellar stability and range of motion (ROM) were analysed. To assess functional improvement and knee pain, the Kujala Anterior Knee Pain Scale and KOOS-Child Knee Survey were used before and after surgical treatment. Results No history of dislocation was noted after surgical treatment. All 15 knees showed full ROM. There were no signs of genu recurvatum and no length discrepancies were found. The subjective assessment revealed significant improvement in the scores of the KOOS-Child questionnaire in all five sections (p < 0.001), as well as in The Kujala Anterior Knee Pain Scale (p = 0.001). Conclusion The modified Grammont and Langenskiöld technique yields remarkable results in terms of knee stability and knee function, while decreasing recurrence risk and intensity of pain in patients with challenging cases of patellofemoral joint dislocation. This surgical technique is most effective in cases where the patella remains dislocated continuously; however, it may also be used in immature patients with recurrent instability. Level of evidence IV.

“…Following approval from our Institutional Review Board, a retrospective study was conducted from September 2016 to March 2019. The patients met the following inclusion criteria: (1) a diagnosis of congenital patella dislocation, (2) no history of knee surgery, and (3) received modi ed Langenskiöld procedure. The patients were excluded if their follow-up period was less than 2 year.…”

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

“…Several techniques have been described to reconstruct the dislocated extensor apparatus, including the Elmslie-Trillat procedure, proximal patellar quadricepsplasty, and medial patellofemoral ligament reconstruction [11], [12], [13], [14]. When severe knee osteoarthritis is present, total knee arthroplasty is a treatment option, which may or may not be associated with realignment of the extensor apparatus to achieve an adequate valgus correction and obtain a correct soft tissue balance [15], [16].…”

Total knee replacement in patients with osteoarthritis and concomitant inveterate patellar dislocation

The inveterate patellar dislocation is an uncommon entity. The most frequent findings correspond to a misaligned valgus associated with lateral patellar dislocation. When severe knee osteoarthritis is present, total knee arthroplasty is an option, whether it is associated or not with realignment of the extensor apparatus. We present a review of published literature on correction of inveterate patellar dislocation associated with knee arthritis and our surgical technique with a case of inveterate patellar dislocation associated with tricompartmental knee osteoarthritis, in which a total knee arthroplasty was performed associated with proximal and distal realignment of the extensor apparatus. Total knee arthroplasty is a useful procedure in knee osteoarthritis associated with inveterate patellar dislocation, which can be associated with techniques on the extensor apparatus to achieve an adequate patellar alignment.
