While comparing between the NMK and MK groups, no significant difference was observed in improvement of the FJS at 6 months.
Better improvement was observed in the MK group than in the NMK group at 12 months (NMK vs MK group: 61.06 ± 6.65 vs 63.75 ± 6.31), 24 months (NMK vs MK group: 80.02 ± 5.75 vs 82.13 ± 5.85), and 60 months (NMK vs MK group: 81.12 ± 5.17 vs 85.67 ± 5.68) (P-value < .05).
