KAYAL ORTHOPAEDIC CENTER · BERGEN COUNTY, NJ
Your Knee. Your Anatomy.Your Life.
Advanced knee replacement surgery designed around you — not a mechanical average. Experience the difference of personalized, anatomic alignment.
A NEW STANDARD OF CARE
Not Every Knee Is Built the Same
Traditional "mechanical alignment" forces every knee into the same straight-line geometry. But your knee was never straight to begin with. We restore your natural anatomy — and the results speak for themselves.
CONVENTIONAL APPROACH
Mechanical Alignment
THE KAYAL APPROACH
Functional & Kinematic Alignment
The Advantages of Anatomic Alignment
Every detail of your implant positioning is guided by your anatomy, your CPAK classification, and your individual joint line — not a textbook average.
Natural Feel
Implants positioned to mimic your pre-arthritic anatomy produce a knee that moves, bends, and feels like your own — not a foreign device.
Optimized Range of Motion
Restoring your native joint line and tibial slope allows for fuller flexion, smoother extension, and more natural gait mechanics.
Balanced Ligament Tension
Kinematic alignment preserves the natural length and tension of the collateral and cruciate ligaments — eliminating unnatural forces that cause pain and stiffness.
Superior Patient Satisfaction
Studies consistently demonstrate higher satisfaction scores when the knee is aligned to the patient's native anatomy rather than a mechanical axis.
Reduced Pain & Faster Recovery
With the Quiet Knee perioperative protocol and anatomically balanced components, patients experience less post-operative pain and return to activity sooner.
Personalized Using CPAK Classification
Your unique Constitutional Phenotype of the Arthritic Knee (CPAK) drives implant selection and positioning — truly individualized surgical planning.
Implant Longevity
Physiologic load distribution across anatomically aligned components reduces wear, stress concentration, and risk of long-term failure.
Activity Without Compromise
Whether you want to walk, golf, cycle, or play with grandchildren — functional alignment gives you back the activities that make life worth living.
Evidence-Based Innovation
Dr. Kayal integrates the most current peer-reviewed science and leading-edge implant technology to ensure you receive care that is both proven and progressive.
PRECISION TECHNOLOGY
Robotic-Assisted Total Knee Replacement
Achieving true anatomic alignment requires sub-millimeter accuracy. Dr. Kayal performs robotic-assisted total knee replacement, combining his expertise in functional alignment with the precision of advanced robotic guidance systems.
The robot doesn't operate — Dr. Kayal does. Robotics simply ensures that every bone cut, every component angle, and every alignment parameter is executed exactly as planned, specific to your anatomy.
NOT EVERY KNEE NEEDS FULL REPLACEMENT
The Oxford Partial Knee Replacement
When arthritis is confined to one compartment of your knee, a partial replacement preserves everything that's still healthy — and delivers remarkable outcomes with far less surgical impact.
OXFORD UNICOMPARTMENTAL SYSTEM
The Oxford Unicompartmental Knee Replacement is one of the most studied and proven partial knee systems in the world, with over 40 years of clinical data. Dr. Kayal offers this minimally invasive solution for patients with isolated medial or lateral compartment disease.
Unlike total knee replacement, the Oxford system preserves your cruciate ligaments, your natural joint surfaces, and your bone stock — creating a knee that moves more naturally because it is more natural.
"The most natural-feeling knee replacement available — because most of your knee is still your own."
Robert A. Kayal, MD, FAAOS, FAAHKS, FACS
ADVANTAGES OF PARTIAL KNEE REPLACEMENT
Bone Preservation
Only the damaged surface is resurfaced — healthy bone and cartilage are left completely intact.
Minimally Invasive
Smaller incision, less muscle disruption, reduced blood loss compared to total knee replacement.
Faster Recovery
Most patients walk the same day and return home within 24 hours — often with an outpatient procedure.
Ligaments Preserved
Both cruciate ligaments remain intact, contributing to a more natural, stable, proprioceptive knee.
Natural Motion
Preserving the healthy compartments maintains your natural kinematics and roll-glide mechanics.
Less Pain
Smaller surgical footprint translates directly to less post-operative pain and reduced need for pain medication.
Proven Longevity
Oxford survivorship data demonstrates excellent outcomes exceeding 20 years in appropriately selected patients.
Revision Option
If needed in the future, conversion to total knee replacement remains fully possible with preserved bone stock.
Higher Activity Level
Patients return to higher-impact activities sooner and report better function than matched TKA patients.
Patient Satisfaction
Consistently higher satisfaction scores — a partial knee often feels indistinguishable from a normal knee.
THE KAYAL DIFFERENCE
The Quiet Knee Protocol
Most of the discomfort patients associate with knee replacement surgery isn't inevitable — it's the result of inadequate perioperative management. The Quiet Knee Protocol is Dr. Kayal's evidence-based, multimodal approach to eliminating unnecessary pain, swelling, and inflammation before, during, and after surgery — so that your recovery is as fast, comfortable, and effective as possible.
The name says it all: a quiet knee is a healing knee. By aggressively controlling the inflammatory cascade from the moment you enter care, we create the optimal biological environment for your new joint to integrate, move freely, and feel natural — from the very first days after surgery.
Silence Inflammation
Targeted anti-inflammatory agents suppress the inflammatory cascade at multiple pathways simultaneously.
Multimodal Pain Control
Layered analgesic strategies minimize opioid requirements while maintaining superior comfort.
Rapid Mobilization
Patients are up and moving the same day — early motion is medicine for the healing joint.
Optimized Recovery
Structured post-operative rehabilitation guided by protocol milestones, not guesswork.
WHAT TO EXPECT
Your Path to a Better Knee
Personalized Consultation
A comprehensive evaluation of your knee, your imaging, and your goals. Dr. Kayal reviews your CPAK classification, alignment profile, and determines whether partial or total knee replacement — and which approach — is right for you.
3D Surgical Planning
Using advanced imaging and robotic planning software, every component angle, joint line, and tibial slope is mapped to your unique anatomy before a single incision is made.
Precision Surgery
Dr. Kayal performs your robotic-assisted procedure with the plan executed to within half a degree of accuracy — restoring the anatomy your knee was born with.
The Quiet Knee Recovery Protocol
A structured, evidence-based perioperative program including optimized pain management, early mobilization, and targeted rehabilitation designed for the fastest, most comfortable recovery possible.
Back to Your Life
Most patients return to full activity within weeks — walking, exercising, traveling — with a knee that feels natural because it was built around their natural anatomy.

THE KAYAL DIFFERENCE
Bergen County's Leader in Advanced Knee Surgery
Dr. Robert A. Kayal is the Founder and CEO of Kayal Orthopaedic Center, one of Bergen County's most respected multi-specialty orthopaedic practices. A board-certified, fellowship-trained orthopaedic surgeon with subspecialty expertise in total joint replacement, Dr. Kayal has dedicated his career to advancing the science and art of knee surgery.
An early adopter of functional and kinematic alignment techniques, Dr. Kayal integrates CPAK-guided surgical planning with robotic assistance to deliver outcomes that go far beyond what conventional mechanical alignment can achieve. His philosophy is simple: a successful knee replacement isn't just one that's technically correct — it's one the patient doesn't think about.
Dr. Kayal treats each patient as an individual, investing the time to understand their anatomy, their lifestyle, and their goals before recommending any surgical approach.
Ready for a Knee That Feels Like Your Own?
Schedule a consultation with Dr. Kayal and discover whether functional alignment, robotic-assisted total knee replacement, or the Oxford partial knee replacement is right for you — and experience the Quiet Knee Protocol from day one.
