DEPENDENCE OF THE DURATION OF SURGICAL INTERVENTION AND FUNCTIONAL ACTIVITY OF THE PATIENT IN THE POSTOPERATIVE PERIOD ON THE TECHNICAL PARAMETERS FOR PARTIAL RESECTION OF THE MEDIAL MENISCUS OF THE KNEE JOINT

Introduction. The study of the duration of surgery and the course of the postoperative period in 38 patients with damage to the medial meniscus of the knee joint who underwent partial meniscus resection in the traditional way was conducted and the analysis of the dependence of the duration of surgery and patient activity in the postoperative period on such technical parameters as the number of resection cycles and the frequency of intraoperative instrument change was performed. The aim of the study. To determine the dependence of the duration of surgery and functional activity of the patient in the postoperative period on the technical parameters of partial resection of the knee meniscus. Materials and methods. The study involved 38 patients aged 21 to 53 years with unstable damage to the medial meniscus of the knee joint of III or IV degree according to Stoller, who underwent partial meniscus resection. To assess functional activity, patients underwent periodic clinical examination and questionnaires using the Tegner activity scale from the first day to 6 weeks after surgery. Statistical processing of the study data was performed using the licensed software IBM SPSS Statistics Base v 22. MedCalc (Healthcare Technology, USA). Results. A direct strong correlation (ρ=0.857) was found between the number of meniscus resection cycles performed during surgery and the number of intraoperative instrument change (p<0.05). A direct strong correlation (ρ=0.725) was found between the number of meniscus resection cycles performed during surgery and the duration of surgery (p<0.05), as well as a direct strong correlation (ρ=0.723) between the number of intraoperative instrument changes and the duration of surgery (p<0.05). There was no correlation between the duration of surgery and the subjective assessment of activity according to the Tegner scale in the period from 0 to 6 weeks postoperatively (ρ is not statistically significantly different from zero, p>0.05). Conclusions. The need for intraoperative instrument change is directly related to the number of resection cycles required to perform partial resection of the medial meniscus. The duration of the surgical intervention is related to the need for intraoperative instrument change and the number of resection cycles required for partial resection of the medial meniscus. However, the functional activity of the patient in the early and medium-term postoperative period is not directly related to the duration of the operation.
