[Purpose] This study aimed to assess the correlation between lateral thrust and clinical symptoms after high tibial osteotomy and determine lower limb alignments that may decrease lateral thrust. [Participants and Methods] We included 54 patients (73 knees) who underwent high tibial osteotomy. Clinical symptoms, including the Japanese Orthopaedic Association score and the hip–knee–ankle angle measured via radiography, were assessed 12 months postoperatively. Lateral thrust was measured using three-dimensional motion analyses. Logistic regression was used to calculate the cut-off values with good Japanese Orthopaedic Association score and lateral thrust as dependent variables and both lateral thrust and hip–knee–ankle angle as independent variables. [Results] The lateral thrust cut-off was 3.1° (sensitivity: 0.83; specificity: 0.74; area under the curve: 0.76), while that of the hip–knee–ankle angle was 1.9° of valgus (sensitivity: 0.71; specificity: 0.81; area under the curve: 0.72). [Conclusion] Good clinical outcomes after high tibial osteotomy can be expected with a lateral thrust of ≤3.0°, indicating that the target hip–knee–ankle angle should be 2.0° valgus. In cases where valgus alignment is insufficient, lateral thrust may develop, which should be assessed using gait analysis.
