No fluff. No fads. Deep-dive investigative reports from the surgeon who actually sees the inside of the joints.
A knee replacement in 2026 is not your parents' knee replacement. The implant your neighbor got in 2006 is still a good design — but how it is sized, rotated, aligned, and balanced has been rewritten twice over.
Replacement is not decided by an X-ray. It is decided by how your knee limits your life. Bone-on-bone imaging without nightly pain is not an indication. Nightly pain with preserved cartilage is not an indication either. Both have to line up.
The best knee replacement is the one that waits until your life says it is time — and the one planned with the precision your anatomy deserves.
Dr. Sameh Elguizaoui, M.D. — Board-Certified Orthopedic SurgeonA robotic-arm-assisted knee replacement is not a robot operating on you. It is a CT-based 3D plan of your knee loaded into a haptic guidance arm that physically prevents the surgeon from cutting outside the planned envelope. Translation: the cuts land where we planned to millimeter precision, every single time.
A low-dose CT of your knee and landmarks becomes a segmented 3D model. Implant size, position, and rotation are planned before we ever touch you.
Small optical trackers pinned to the femur and tibia let the system know where your leg is in space at 0.1 mm accuracy.
Before any bone is cut, we dynamically tension the knee through its full range and watch the software quantify medial and lateral gaps in millimeters — then tweak the plan.
The robotic arm holds the cutting saw inside a virtual fence. Step outside the plan and the arm stops. It is boring when it works — which is exactly what you want.
Every knee replacement has to decide: do we line up the implant with the mechanical axis (a straight line from hip to ankle) or with the kinematic axis (the knee's natural asymmetric flexion axis)?
Tradition
Anatomy-respecting
The pragmatic answer in our practice is restricted kinematic alignment — a hybrid that respects your anatomy within safe limits but never lets varus or valgus push beyond evidence-backed boundaries.
"Too young" used to mean under 60. Modern implants and alignment techniques now let active patients in their 50s — even late 40s with severe disease — have replacements that are likely to outlast them. The right answer is individualized, not age-based.
Most patients can kneel comfortably by 6 months. It feels different — there is a prosthetic kneecap under the skin — but it is safe.
For isolated medial or lateral compartment arthritis with intact ligaments, partial replacement is a better operation than a total — smaller incision, faster recovery, more native feel. Robotic planning has made unis more reliable.
Yes — typically aspirin for 3–4 weeks in standard-risk patients. Higher-risk patients get a low-molecular-weight heparin or DOAC. Protocols are individualized.
Infection (<1%), blood clot (<1%), persistent stiffness requiring manipulation (2–5%), and unhappy but well-aligned knees (<5%). The last is the biggest long-term concern and is exactly what modern alignment work is designed to prevent.
