  1. FL, Functional Level; TSS, Time since surgery (years); SL, Surgical limb; L, Left; R, Right; FTR, Femur to tibia ratio; SSWS, Self-selected walking speed (m/s); ‘Reason’ indicates why the participant was a candidate for rotationplasty; SACH, Solid ankle cushioned heel.
  2. ’High’ functioning group having a knee dynamic peak range > 40°.
  3. ’Low’ functioning group having a knee dynamic peak range < 40°.
