Snow in Moscow, Sparks on the Podium: Keynote Reflections from the Russian Veterinary Congress
Back in December 2024, I traveled across Eurasia to the snow-blanketed capital of Russia with a focused academic mission: presenting seven years of clinical breakthroughs in canine knee reconstruction to our international colleagues. At the Partners Science Forum Annual Veterinary Congress in Moscow, I shared our Chinese surgical protocols and biological total knee arthroplasty (TKA) data with hundreds of Russian practitioners. The congress concluded with an unexpected and humbling honor: being presented with the Professional Excellence Award for surgical breakthroughs—an accolade I joked that I hadn't even achieved back home in China. But beyond the standing ovations and heated biomechanical debates, what anchored this journey in my heart was something purely personal: as a surgeon born and raised in subtropical Guangzhou, this trip was the very first time in my entire life that I saw falling snow.
Custom 3D-Printed Biological Total Knee Arthroplasty (TKA) in a Dog: Clinical Case and 2.5-Month Outcome
In this case, I document what was the first reported biological canine total knee arthroplasty (TKA) using custom 3D-printed implants and disposable patient-matched instrumentation in China. The patient, a 25 kg Husky, suffered from end-stage osteoarthritis and severe meniscal damage triggered by chronic cranial cruciate ligament rupture. Facing a complete lack of off-the-shelf knee prostheses suited to this dog, my surgical team at Guangzhou Boss Animal Hospital collaborated with Associate Professor Zhang Jun and the materials engineering team at the Guangdong Academy of Sciences. Together, we designed and 3D-printed a cementless CoCrMo/porous titanium/Vitamin E-stabilized polyethylene implant system. Following 1:1 benchtop simulation, we successfully placed the prosthesis. By day one post-op, the dog was weight-bearing without pain; at 2.5 months, he was galloping freely off-leash across the grass.
