Outcomes of Below-the-Knee Amputations for Chronic Lower Extremity Pain.

The study evaluated the physical,mental, and functional outcomes following below-the-knee amputation (BKA) for management of chronic, debilitating lower extremity pain. The hypothesis was that patients who undergo a BKA to alleviate chronic pain achieve a greater level of function, experience decreased pain, and benefit from improved health-related quality of life. Patients who received a BKA attended an orthopaedic clinic and completed questionnaires examining their overall health, functional status, mental health, and pain. Thirty-seven patients were identified as eligible for study participation; 15 agreed to participate. Although most participants continued to experience pain in their residual limb after BKA, they reported their pain decreased to a manageable level. Participants experienced a statistically significant improvement in their perceived physical health. The authors believe a BKA for chronic pain is a reasonable treatment option for patients who continue to experience lower extremity pain after failed medical and surgical management of chronic pain.
