The progression and proposed future of WB rehabilitation since the inception of the general ACI procedure; (A) WB gradient proposed by Minas and Peterson14, whereby loading is limited to toe-touch for 6 weeks, one third of BW permitted during weeks 7 and 8, two thirds of BW permitted through weeks 9 and 10, and full WB as tolerated through weeks 11 and 12, (B) WB gradient proposed by Robertson et al.7, whereby a much more graduated increase is permitted, progressing from 20% of patient BW within 2 weeks of the operation, through to full WB at 3–4 months post-surgery, removing the initial 6-week period of non-WB, and (C) proposed accelerated WB gradient following MACI designed to attain full WB at 8 weeks post-surgery.

Summary of gait for both patient groups (accelerated and traditional) and their respective control groups, throughout the stance phase of gait. These included the following: (A) knee flexion angle; (B) vertical GRF; (C) external knee adduction–abduction moment; and (D) external knee flexion–extension moment.
