Transfemoral Amputation

The mean follow-up after Stage 2 was 13.2 years, and more than half of the cohort had at least 10 years of follow-up. Osteoarthritis prevalence was likely underestimated in this study because radiographs and standard OA symptom screening were not routinely performed. People with lower-limb amputations are known to have an increased long-term risk of contralateral hip and knee osteoarthritis and ipsilateral osteopenia or osteoporosis. Increased fall risk after lower-limb amputation may contribute to the elevated fracture rates observed in amputees. Patients with transfemoral BAPs may have higher risks of femur fracture and arthroplasty surgery than the general population, but larger comparative studies are needed to confirm this. Trauma was the most common cause of transfemoral amputation in this cohort, accounting for 70% of patients.
