Orthopedic Surgeon Using Recently Approved Partial Knee Implant
William “Bill” D. Lawrence, D.O., is one of a few surgeons in the Metro area to perform partial knee replacement surgery utilizing the Oxford® Partial Knee System.
Leading surgeons in Oxford, England, along with engineers at Biomet, headquartered in Warsaw, Indiana, developed the partial knee system, which until last year was not available in the U.S. The Oxford® Knee is the only FDA-approved Free Floating Meniscal Partial knee system available in the United States and has been utilized throughout Europe for more than two decades.
Often recognized as the most widely used and clinically proven partial knee system in the world, the Oxford® Knee System has demonstrated excellent clinical results. Surgeons in the U.S. now have access to this system whose clinical results have equalled that of the most successful total knee replacements.1 Unlike total knee replacement involving removal of all the knee joint surfaces, a partial knee replacement replaces only one side of the knee joint. Knee osteoarthritis usually occurs first in the medial (inside) compartment, as this side of the knee bears most of the weight. In knees that are otherwise healthy, a partial approach allows the outer compartment and all ligaments to remain intact. By retaining all of the undamaged parts, the joint may function more naturally.
In a healthy knee, the meniscal cartilage serves as a shock absorber between the ends of the bones. The Oxford® Knee is the first partial implant with an artificial meniscal bearing designed to glide freely throughout the knee’s range of motion to more closely replicate normal movement. The free floating nature of the device also greatly improves durability of the implant.
The Oxford® System offers a precisely instrumented system designed to balance the soft tissues and to accurately reproduce normal knee motion. The Oxford® Knee may also allow for a more rapid recovery due to the use of minimally-invasive instrumentation and technique. With proper use of the Oxford® instruments, the operation can be performed through a small incision with great precision.
Surgeons in the U.S. who wish to use the Oxford® System are required by the FDA to attend an advanced instructional course on the device.
