Abstract :Purpose:our aim is to reveal the technical errors and rnangular deformities related to the application in MİUCA, using the radiological evaluation criteria rnof the Oxford group, the most common implant application defects.rn Patients and Methods: 14 knee of 13 men and 90 knee of 80 women were included in the study. Average female age; 56.38 insert ignore into journalissuearticles values( range: 46-74 ); and average male age; 57.80 insert ignore into journalissuearticles values( range: 48-66 );. Average age; 57.12 insert ignore into journalissuearticles values( range: 46-74 ); Average follow-up time: 58 months insert ignore into journalissuearticles values( range: 3-104 );, 82 fix-beaing, 22 mobile-bearing MIUCA were applied. In the preoperative period: we evaluated the degree of OA in the medial joint with standard bilateral knee radiography and the flexibility of varus deformity with valgus stress test. In the postoperative evaluation; Radiological measurements recommended by the Oxford knee group were performed by routine two-way knee radiography. The knees applied to MIUCA were evaluated with 17 criteria suggested by the Oxford group as a whole. Results:Tibial component: Varus / Valgus: Two patients were found outside the range of -4 insert ignore into journalissuearticles values(valgus); and 8 insert ignore into journalissuearticles values(varus); degrees. Slope: In two knees insert ignore into journalissuearticles values( 8 and 10 degrees );, slope was measured outside the normal limit. Overflow in the implant: 11 knee posterior, 2 knee anterior and 2 knee overflow from the medial plateau were seen. Femoral component: Valgus-Varus position: Average of 34 knee valgus: 5.41 insert ignore into journalissuearticles values( range: 3-10 degrees );, 19 knee varus. Average: 4.58 insert ignore into journalissuearticles values( range: 4-8 degrees );. Flexion-Esthesion status: 52 knee flexion, mean: 3.95 insert ignore into journalissuearticles values( range: 2-35 degrees ); measured. 21 knees were measured over 5 degrees of flexion. Conclusion:In our patients, where we applied MUCA; Increased error in femoral component: application of the prosthesis in flexion insert ignore into journalissuearticles values( above 21 knee-5 degrees );, the most common error in the tibial component: prosthesis overflow insert ignore into journalissuearticles values( 11 knees );.
