Abstract

Background. Treatment of chronic ankle instability can currently be performed using various methods. Two popular and frequently used techniques are the Brostrom procedure, performed using the classic open technique, and the arthroscopically assisted Brostrom procedure. The wealth of available data does not provide a clear understanding for traumatologists and orthopedists regarding the criteria for selecting the appropriate surgical treatment strategy.

Aim: To identify the proportion of unsatisfactory outcomes of the two most common surgical treatment methods for patients with chronic lateral ankle instability and the causes of these outcomes, in order to clarify the indications for choosing surgical treatment methods for this group of patients.

Materials and methods. The study was retrospective and included an analysis of archival data and a subsequent in-person examination of 80 patients treated for chronic ankle instability at the R.R. Vreden National Medical Research Center of Traumatology and Orthopedics from January 2021 to February 2024. The average time from surgery to follow-up was 15.5 ± 4.8 months.

Results. A significant reduction in pain severity was observed in both subgroups (p < 0.05). A significant improvement in the KAFS and AOFAS scores was also found after surgery in both groups. Comparisons of different numbers of fixators used did not reveal statistical significance. When comparing the results of using different fixator materials, a correlation was found between the use of plastic fixators and their migration with instability recurrence. We also identified a number of complications after using these techniques: fixator migration, instability recurrence, neuropathy of the cutaneous branch of the peroneal nerve, and marginal skin necrosis.

Conclusion. A number of unsatisfactory results were identified that require further study to develop an algorithm for the traumatologist-orthopedist when choosing a surgical treatment strategy for patients in this profile.
