Muscle strength recovery of the non-reconstructed knees in relation to the preoperative normal knees was investigated. Quadriceps muscle strength was significantly weaker in the C-BTB group at 5 months after surgery (Quad.: 74.5 ± 14.4% in the C-BTB vs. 118.7 ± 27.4% in the I-BTB; p = 0.0021, Ham.: 127.6 ± 20.4% in the C-BTB vs. 134.6 ± 26.3% in the I-BTB; p = 0.60). Moreover, the quadriceps muscle weakness continued at 12 months (Quad.: 103.4 ± 11.5% in the C-BTB vs. 134.2 ± 22.9% in the I-BTB; p = 0.023, Ham.: 121.0 ± 24.9% in the C-BTB vs. 133.8 ± 25.7% in the I-BTB; p = 0.40)
