### Demographics, Outcomes, and Success Rates  
We included 10 studies, which were all in English. The studies involved 546 participants and were published between 1997 and 2020. There were three studies conducted in Finland [22; 23; 24], two in Brazil [25; 26], one in Germany [27], one in Denmark [28], one in Sweden [29], one in China [30], and one in Serbia [31]. The age at the beginning of treatment varied significantly between studies. The youngest participants were 8 years old [24], while the oldest were 74 years old [26].  
[PERSON] et al. did not report on age. Only three studies involved a purely pediatric population: those by [PERSON] et al. [29] (age range 9-14 years), [PERSON] et al. [24] (8-16 years), and [PERSON] et al. [31] (12-16 years). In many of the studies, there was a prevalence of female participants, except for the one by [PERSON] et al. [22], in which there were only three female patients, as the study examined a military population.  
Table 1 shows all the articles that met the inclusion criteria. All studies included were accurately read, and the values of the outcomes are shown in Table 2. In all 10 articles, the re-dislocation rate was observed as an outcome. All studies, except for those by [PERSON] et al. [23] and [PERSON] et al. [31], found a lower re-dislocation rate among patients with surgical treatment.
