Major lower limb amputation in elderly patients is a dreaded event with high mortality and morbidity. Peripheral arterial disease is the nearly exclusive etiology. The aim of this retrospective study was to assess the feasibility of through-knee amputation, and the morbidity and mortality risk in the elderly (>65 years).
From January 2000 to October 2010, 65 Gritti-Stokes through-knee amputations were performed in 58 patients (30 women, 28 men; mean age 79 years). Acute limb ischemia was the most common cause (40%). The others indications were: severe peripheral arterial disease with extensive necrotic lesions (19%), diabetic foot ulcers (15%), non-healing below-knee amputation (10%) and vascular graft infection after prosthetic lower extremity bypass surgery (6%).
Overall 30-day mortality was 24% (n=14/58). Vascular morbidity was 9% (n=6/65). The mean hospital stay was 31 days (range 3 to 96). The overall healing rate was 78% (n=51/65). Conversion to above-knee amputation for failed Gritti-Stokes amputation was performed in one patient.
Gritti-Stokes amputation is feasible in the elderly with an acceptable one-month mortality and a satisfactory overall healing rate. Most amputations are necessitated by complications of acute limb ischemia. For this subpopulation, Gritti-Stokes amputation should be the standard amputation level. The data collected in this study provide important information that can be useful before amputation for this population, their families and primary care physicians. Ambulation is an important postoperative goal and a multidisciplinary approach in specialized centers is required to achieve good wound healing rates.
