BACKGROUND: More than 100,000 major lower extremity amputations -- amputations at the metatarsal, below-knee or above-knee level -- are performed yearly in the United States. Despite improvements in long-term outcome, operative mortality following such amputations has remained stable at 9% to 10% over the last 20 years. Several predictors for functional outcome of amputee patients are mentioned in the literature. OBJECTIVES: The current study was planned to assess the impact of comorbidities on functional status after lower extremity amputations. MATERIALS AND METHODS: It was a prospective comparative study held at the Department of Orthopaedics and Traumatology, Punjab Medical College, Faisalabad, and affiliated hospitals. The study included 104 patients regardless of age and gender. Patients were allocated into trans-metatarsal (TM) group, below-knee (BK) amputation group and above-knee (AK) amputation group. Comorbidities before amputation included diabetes mellitus (70.7%), coronary heart disease (57.1%), chronic kidney disease (53.6%), and/or congestive heart failure (52.1%). RESULTS: Mortality within 30 days of hospital discharge was 9%, and hospital readmission was 27.7%. Stroke, end-stage renal disease (ESRD) and poor baseline cognitive function were associated with the poorest functional outcome after amputation. Patients undergoing BK or AK amputation failed to return to their functional baseline within 6 months. CONCLUSIONS: Higher amputation level, history of stroke, ESRD, poor baseline cognitive scores, and female gender are factors associated with inferior functional status after amputation.
