Ретроспективный анализ результатов оперативного лечения пациентов с остеохондральными повреждениями блока таранной кости

Abstract

Introduction Differences in the reported results lead to the lack of comprehension of whether the size of osteochondral lesion of talar dome is too big for successful usage of arthroscopic microfracturing and osteochondral autologous transplantation would be more preferrable. Aim To elicit the rate and causes of poor results after using two most common methods of operative treatment of patients with osteochondral lesions of the talus (OCLT) for elaboration of indications for surgical method of choice for this category of patients. Materials and methods This was a retrospective study that included analysis of archive data and subsequent examination of 80 patients (80 ankle joints), who underwent treatment for symptomatic OCL of the talus from 2014 to 2020. Mean time from the operation to examination was 20.5 ± 19.8 months. Results A significant increase in the results of FAOS, AOFAS and VAS scales after operative treatment were observed, as well as a significant decrease in lesion sizes (р < 0.05). Overall patient satisfaction and intensity of preoperative pain syndrome showed strong positive correlation with the sizes of lesions on preoperative CT scans, especially with relative sizes. The data analysis revealed the borderline values of relative OCLT sizes, thus allowing us to divide the results of treatment into predictably poor and predictably good. Discussion The elicited borderline values of relative OCLT sizes as well as elicited correlations can be used to specify indications for choosing the method of operative treatment for this group of patients, but further prospective evaluation should be carried out. Conclusion The borderline values of the relative OCLT sizes were found that allow for division into predictably good and poor treatment outcomes.
