Abstract Two technics of below the knee amputation-rehabilitation are presented. The results of a standard operative technic are compared with those of amputation with immediate postoperative fitting of a prosthesis. In every parameter of comparison the group receiving an immediate postoperative prosthesis was superior as evidenced by a zero mortality compared to 15 per cent in the standard group, an 85 per cent primary healing rate compared to 53 per cent, and 100 per cent rehabilitation compared to 85 per cent. The time from amputation to fitting of a permanent prosthesis was 32 days in the group with an immediate postoperative prosthesis as compared to 125 days in the standard amputation series. A combination of factors comprising the immediate postoperative prosthesis program, including a long posterior flap, rigid dressing, and immediate ambulation, seems to account for the improved results in this amputation series.
