FRONTAL STABILITY OF THE KNEE JOINT AFTER TKA USING A COMPUTER NAVIGATION SYSTEM

The article provides a comparative analysis of the functional results of total knee arthroplasty and knee postoperative stability in the frontal plane in 124 patients (22 men and 102 women) suffering from gonarthrosis, aged 51 to 83 years (average 69.8 years), operated on with using a standard technique (n = 62) or using a computer navigation system (n = 62), observed for 12 months from the moment of surgery. The use of the navigation system made it possible in a number of cases to achieve more accurate resection of the femur and tibia (deviations from the anatomical axis in 6.5 % of cases versus 19.4 % in the control group), as well as to provide the necessary soft tissue tension to achieve the most accurate balance of the knee joint during the entire range of motion after arthroplasty (stress tests founded frontal plain knee instability of the operated knee in 3.2 % cases in navigation group versus 8.1% cases in control group), however, no data on the reliable superiority of the functional results at the indicated follow-up time were found.

Endoscopic sinus surgery using a computer navigation system

According to world statistics, of ENT pathology (throat, ear and nose) is among the most common diseases. About 30% of the world’s population constantly suffers from ENT pathology, which leads to a deterioration in the quality of life and disability. One of the most common pathologies of the upper respiratory tract is diseases of the paranasal sinuses (PNS). To date, maximum functionality and minimal trauma to the surgical treatment of ENT diseases, can achieve a functional minimally invasive surgery (Functional Endosocopic Sinus Surgery, FESS), in which the restoration of the natural ventilation and drainage pathways occurs with minimal trauma to the mucous membrane and the anatomy of the structures of the nose and PNS with local surgeries under constant endoscopic control. Endoscopic sinus surgery is a widely used method of surgical treatment of diseases of the nose and paranasal sinuses.The article analyzes the various methods of endoscopic surgery of the paranasal sinuses, describes their positive and negative sides, including the use of a computer navigation system. Data search was carried out in the database PubMed, CRD, Cochrane etc. by keywords. The search for modern solutions of endoscopic sinus surgery determines the relevance of the navigation system in sinus surgery.
