When the side-to-side muscle strength ratio were evaluated, the strength of the quadriceps and hamstring muscle was not different between the two groups preoperatively (Quad.: 75.4 ± 19% in the C-BTB vs. 84.6 ± 21% in the I-BTB; p = 0.194, Ham.: 92.5 ± 18.7% in the C-BTB vs. 86.9 ± 17.8% in the I-BTB; p = 0.49). However, quadriceps muscle strength in the C-BTB group was significantly higher than that in the I-BTB group at 5 months (Quad.: 120.6 ± 24.5% in the C-BTB vs. 70.0 ± 12.3% in the I-BTB; p < 0.001, Ham.: 95.6 ± 17.2% in the C-BTB vs. 97.4 ± 23.9% in the I-BTB; p = 0.055) and 12 months (Quad.: 96.9 ± 12.4% in the C-BTB vs. 76.0 ± 17.6% in the I-BTB; p = 0.018, Ham.: 95.3 ± 13.3% in the C-BTB vs. 97.9 ± 12.8% in the I-BTB; p = 0.74) postoperatively
