The management of acute acromioclavicular dislocation. A randomised prospective controlled trial. Conservative versus surgical treatment for repair of the medial patellofemoral ligament in acute dislocations of the patella.
In a prospective study, 60 patients with acute acromioclavicular dislocation were randomly allocated to treatment with a broad arm sling or to reduction and fixation with a coracoclavicular screw. Of these 54 were followed for four years. Conservatively-treated patients regained movement significantly more quickly and fully, returned to work and sport earlier and had fewer unsatisfactory results than those having early operation. For severe dislocations, with acromioclavicular displacement of 2 cm or more, early surgery produced better results. Conservative management is best for most acute dislocations, but younger patients with severe displacement may benefit from early reduction and stabilisation. The objective of this study was to analyze and compare the results obtained after 2 types of treatment, surgical and conservative, for acute patellar dislocations.
                We divided 33 patients with acute patellar dislocations into 2 groups. One group with 16 patients underwent conservative treatment (immobilization and subsequent physiotherapy), and the other group with 17 patients underwent surgical treatment. A radiographic examination was performed in the evaluation of the patients to verify predisposing factors for patellofemoral instability, and the Kujala questionnaire was applied with the intention of analyzing the improvement of pain and quality of life. The chi(2) test, t test, and Fisher test were used in the statistical evaluation. A significance level of P < .05 was adopted.
                The groups were considered parametric in relation to age and sex. The conservative treatment group exhibited a higher number of recurrent dislocations (8 patients) than the surgical treatment group, which did not have any relapses. In addition, the surgical treatment group obtained a better mean score on the Kujala test (92) than the conservative treatment group (69).
                We conclude that surgical treatment afforded better results. There were no recurrences in the surgical treatment group, but there were 8 recurrences in the conservative treatment group. The mean Kujala score was 92 in the surgical treatment group and 69 in the conservative treatment group.
                Level II, lesser-quality therapeutic randomized controlled trial.
There is insufficient evidence from randomised controlled trials to determine when surgical treatment is indicated for acromioclavicular dislocation in adults in current practice. Sufficiently powered, good quality, well-reported randomised trials of currently-used surgical interventions versus conservative treatment for well-defined injuries are required.
