Genesys conducts new FDA-approved minimally invasive partial knee replacement surgery

Editor's note: Dr. Schreiber and Dr. Sorscher are available for an interview. Two patients who successfully had the procedure also are available for an interview. Photos of Dr. Schreiber conducting the surgery also are available.
(GRAND BLANC, MI) Orthopedic surgeons at Genesys now can offer patients an alternative to a full knee replacement with the FDA approval of the "Oxford knee," the only FDA-approved fully mobile-bearing partial knee system in the country.

Only a handful of orthopedic surgeons in the entire state and about 200 in the US have obtained the necessary training the FDA requires to conduct the minimally invasive technique. Two of these surgeons practice at Genesys and have conducted many procedures - Frederick Schreiber, DO; and Michael Sorscher, MD. A third - Todd Sandrock, DO; recently completed the training.

The new partial knee has shown a 98 percent success rate at 10 years, equaling the results of the most successful total knee replacements, studies have revealed. Unlike total knee replacement that removes all knee joint surfaces, a unicompartmental knee replaces only one side of the knee joint, explains Dr. Schreiber. Knee osteoarthritis usually occurs first in the medial (inside) compartment because this side of the knee bears most of the weight. If the knee is otherwise healthy, a unicompartmental approach allows the outer compartment and all ligaments to remain intact. By retaining all of the undamaged parts of the knee, the joint may bend better and function more naturally, he adds. This new knee system is intended to preserve the healthy knee structures and restore normal knee motion and function.

The new system includes a special artifical bearing not fixed to the tibial component, allowing it to glide freely throughout the knee's range of motion to more closely replicate normal movement. Patients report that the partial knee feels more like their own knee, Dr. Schreiber finds.

Other improved benefits when comparied to traditional full knee replacement surgery include:
  • less tissue removed (only damaged cartilage is removed)
  • faster recovery
  • shorter hospital stay
  • less invasive
  • small incision
  • less pain
  • return to daily activities sooner (usually four to six weeks after surgery)

Traditional knee replacement usually involves resurfacing the damaged cartilage at the end of the thighbone, the top of the shinbone and sometimes the back of the kneecap.
