In the NMK group, there was a significant improvement in patients' Kujala score from preoperative to different stages of follow-up, and a similar trend was also observed in the MK group (P-value < .05).
While comparing between the NMK and MK groups, no significant difference was observed in improvement of the score at 6 months.
Better improvement was observed in the MK group than in the NMK group at 12 months (NMK vs MK group: 51.7 ± 2.5 vs 55.8 ± 2.7), 24 months (NMK vs MK group: 58.4 ± 2.1 vs 64.8 ± 2.8), and 60 months (NMK vs MK group: 57.6 ± 2.0 vs 68.1 ± 2.2) (P-value < .05).
