PURPOSE: According to the severity of knee valgus, different operative approaches were applied in total knee replacement. Hence, we assessed the safety and efficacy of different operative approaches in the level IV study. METHODS: From May 2011 to March 2014, a retrospectively analysis was conducted among 31 patients with knee valgus (mild in 10 cases, moderate in 8 cases and severe in 13 cases based on Keblish grade). Medial approach trip knee replacement was performed in mild and moderate patients, which were assigned as medial approach group. Lateral approach was performed in severe patients, which was assigned as lateral approach group. Relevant results were compared between medial approach group and lateral approach group, including valgus corrected angle, postoperative knee joint activity and Kss score. Furthermore, operative time, postoperative blood loss, patellar trajectory and anterior knee pain were also compared between the two groups. RESULTS: All operations were successful without obvious complications. In medial approach group, postoperative knee valgus angle was (7 ± 1)°. Three months after operation, degree of knee joint activity was (85.2 ± 5.2)°, and KSS score of knee joint was (80.1 ± 5.2). Significant differences were detected in these compared with preoperative data (all P < .05). Moreover, similar results were found in lateral approach group with postoperative knee valgus angle as (8.2 ± 2.3)°, degree of knee joint activity three months after operation ...
