Good | Union + any two of the following: absence of infection, deformity < 7°, and limb length discrepancy of 2.5 cm | Active with one or two of the following: limp, stiffness, RSD, and significant pain |
Fair | Union + one of the following: absence of infection, deformity < 7°, and limb length discrepancy of 2.5 cm | Active with three or all of the following: limp, stiffness, RSD, and significant pain |
