[Below-knee amputation according to Robb-Persson. Technique and clinical results].

The successful rehabilitation and the quality of life of below-knee amputees depend to a great extent on the load-bearing capacity of the amputation stump. Robb and Persson's operating method, utilizing a sagittal cut was used in 154 be low-knee amputations in the period 1982-1992 that were retrospectively analysed. In 91% of the cases, advanced vascular disorders related to diabetes mellitus were the main cause for the loss of a limb. Postoperative mortality amounted to 31.8%, the re-amputation rate was 4.5%. Rehabilitation up to full walking capability was achieved by 75% of the surviving patients. 46 patients were re-examined between 1 and 6 years after amputation. In 85% of the cases the condition of the stump was found to be good to very good. The functional rehabilitation results are comparable to those of other operating methods. The advantages of the Robb-Persson below-knee amputation method are the simplicity of the technique and a secure and longlasting effective stump cover, resulting in favourable long-term results.
