No. 003: September-October 2019

This month, we are honored to feature an interview with Professor Carsten Perka, Medical Director of the Charité in Berlin. His career, shaped in part by a personal experience with osteomyelitis, reflects a sustained commitment to clinical rigor and institutional leadership in German arthroplasty. Through his roles in the DKOU and the national registry, he has contributed to standardizing arthroplasty practice nationally, while his focus on translational medicine continues to bridge regenerative science and surgical decision-making.

The clinical articles address two major domains. In revision acetabular surgery, contributions examine cup-cage reconstruction for severe acetabular bone loss and pelvic discontinuity alongside patient-matched 3D-printed implants for Paprosky 3 acetabular defects guided by bone quality assessment. In primary knee arthroplasty, the issue explores an extension gap first technique applying adjusted mechanical alignment to minimize soft tissue releases, complemented by a systematic approach to total knee arthroplasty in posttraumatic osteoarthritis.
