ROSA Knee Robotic Replacement Surgery at Asklepios Clinic Barmbek

At the Asklepios Clinic Barmbek in Hamburg, we specialize in high-precision knee restoration using the ROSA Knee System, a state-of-the-art robotic assistant that enables surgical personalization and accuracy that exceeds traditional manual methods. A key advantage of our clinic is the ability to perform not only total joint replacements but also partial knee replacements, often referred to as unicompartmental knee arthroplasty or "sled prostheses" (Schlittenprothese). This approach is designed to preserve as much of your healthy bone, cartilage, and ligaments as possible by replacing only the specific damaged compartments of the joint. The ROSA (Robotic Surgical Assistant) technology functions as a high-tech GPS for the surgeon. Before the procedure, the system uses specialized X-rays to create a 3D digital model of your knee. During surgery, the robotic arm provides real-time data to the surgeon, accounting for the tension of your ligaments and the specific geometry of your joint. This is particularly vital for partial "sled" replacements, where the transition between the natural bone and the implant must be seamless. The robot enables ultra-precise bone cuts and optimal implant positioning, which are critical for the long-term stability and "natural feel" of the new knee. The operation is performed under general or regional anesthesia by our specialized orthopedic team. Unlike conventional surgery, the ROSA system enables a minimally invasive approach that better protects the surrounding soft tissues, tendons, and nerves. Because the robot ensures the bone is prepared with sub-millimeter precision, the fit of the prosthesis, whether it is a partial sled or a full replacement, is exceptionally secure. The procedure typically lasts between 60 and 90 minutes, during which the surgeon maintains full control, using the robot’s data-driven insights to refine the alignment to your specific gait and movement patterns. Post-operative care begins immediately in our specialized recovery area, where we prioritize effective pain management. A key advantage of the ROSA robotic system, especially when combined with partial joint preservation, is the potential for faster functional recovery. Because robotic assistance enables better ligament balancing and less tissue trauma, many patients experience less postoperative swelling. Mobilization starts on the very day of surgery or the first morning after, supported by our experienced physiotherapy team. You will begin with guided walking exercises, gradually increasing your range of motion and transitioning from walking aids to independent movement and stair climbing by the time of discharge. For robotic knee replacement at Asklepios Barmbek, we utilize premium-grade biocompatible materials designed for longevity:Femoral and Tibial components: High-performance cobalt-chromium or titanium alloys;Articulating surface: Advanced, highly cross-linked polyethylene (XLPE) for minimal wear and tear;Fixation: Highly stable bone cement or cementless "press-fit" options, depending on bone quality. Patients typically remain in our inpatient care for approximately five to seven days. During this period, we conduct regular clinical checks and intensive physical therapy to ensure the joint functions properly. The surgical wound usually heals within 14 days, at which point sutures are removed. While any surgery carries minor risks, such as infection or thrombosis, the robotic precision of the ROSA system is designed to minimize complications, including implant misalignment or instability. At Asklepios Barmbek, our goal is to return you to an active, pain-free life using the most advanced robotic tools available in modern medicine.
