A 29-year-old man from Zurich, Switzerland, has made history by undergoing a double hand transplant, a procedure that has been described as a “medical marvel six years in the making.” Luka Krizanac was just 12 years old when a life-threatening infection led to the amputation of parts of his arms and legs after doctors incorrectly treated the condition. Despite relying on prosthetic legs over the years, Krizanac struggled with prosthetic hands that couldn’t replicate the movements of real hands. Speaking to Penn Medicine, he expressed the challenges of not being able to fully develop as a person without hands and constantly needing assistance for even the most basic tasks.

In 2016, Krizanac was connected with Dr. L. Scott Levin and Dr. Benjamin Chang from Penn Medicine’s hand transplant program to explore the possibility of a double hand transplant. A team of skilled medical professionals was assembled to prepare for and carry out the intricate surgery. Despite facing challenges due to the COVID-19 pandemic, the team persevered, and in fall 2024, Krizanac traveled to Philadelphia to await a suitable donor. Matching for blood and tissue type, as well as gender, skin color, and size, were crucial factors in finding a compatible donor for the transplant.
After eight weeks on the waiting list, Krizanac received the life-changing news that a donor was available through the Gift of Life Donor Program. The emotional significance of this gesture was not lost on Krizanac, who expressed deep gratitude for the donor’s selfless act. In a 10-hour surgery, nearly 17 years after his initial amputation, Krizanac received new hands in what was deemed a “medical marvel” by the hospital staff. Dr. Levin highlighted the profound impact the surgery had on Krizanac’s life, emphasizing the meticulous care taken by the surgical team throughout the process.
Following the surgery, Krizanac embarked on a journey of recovery back in Switzerland. After six months, he has regained the ability to perform tasks that were previously impossible for him, such as typing on his phone, picking up food, and holding objects. The progress in his nerve healing and regaining sensation in his new hands has been nothing short of miraculous for Krizanac. He will continue with regular physical therapy sessions over the next few years to support his ongoing recovery.
Reflecting on his transformative experience, Krizanac shared a poignant moment from his post-operative period when he marveled at his new hands and felt a profound sense of completeness. Despite the challenges and hurdles he has faced, Krizanac’s journey exemplifies resilience, hope, and the incredible advancements in medical science. His story serves as an inspiration to many, showcasing the power of human kindness, perseverance, and the remarkable possibilities that modern medicine can offer to improve lives.
