The Republican Scientific and Practical Seminar "Modern Approaches to Large Joint Arthroplasty" was held at the Republican Scientific and Practical Centre for Traumatology and Orthopedics. Leading orthopedists from Belarus and Switzerland conducted a unique masterclass for 20 Belarusian specialists. A key feature of the event was the use of innovative instruments. This advanced technique enables implant placement that takes the patient's individual anatomy into account with maximum precision. Belarus became the first country in the CIS to implement this approach, thereby cementing its status as the region's technological leader in the field of orthopedics.
