Conservative Care
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 compartment disease. Dr. Kayal is one of only a few orthopaedic surgeons in the state of New Jersey certified to perform both the cemented and cementless Oxford unicompartmental knee replacement.
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. In addition, unlike total knee replacement surgery, the partial knee replacement allows patients to kneel on the knee after surgery.
"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 as outpatients.
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 medication.
Proven Longevity
Oxford survivorship data demonstrates excellent outcomes exceeding 20 years in appropriate patients.
Revision Option
If needed, 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.
