Minimally Invasive Knee Surgery Available at Unity Hospital
Total knee replacement surgery is typically not recommended for people younger than 60 years old, because of the high probability that knee replacements wear out in younger patients’ lifetimes. Often, people younger than 60 years old with knee damage will live with chronic pain and limited movement of the knee for many years.
Partial knee replacement, also called a unicompartmental knee arthroplasty, is an option that is growing in popularity for people with severe arthritis of the knee who have tried non-surgical treatments such as pain management, cortisone injections, strengthening exercises and weight loss. Patients with only limited knee arthritis may choose to have partial knee replacement. Unlike total knee replacement that removes all the knee joint surfaces, a partial knee replacement replaces only one side of the knee joint.
In 2004, Mark Stenclik, M.D., an orthopaedic surgeon affiliated with the Joint Replacement Center at Unity Hospital, was one of the first surgeons in the United States to be trained to perform partial knee replacement surgery utilizing the Oxford® Unicompartmental Knee System. Dr. Stenclik is performing the partial knee replacements at The Joint Replacement Center at Unity Hospital to qualifying patients as young as fifty years old.
“The Oxford® Knee System had demonstrated excellent clinical results,” said Mark Stenclik, M.D. “Surgeons with access to this system report clinical results that equal that of the most successful total knee replacements.”
More Natural Motion
Unlike total knee replacement involving removal of all the knee joint surfaces, a unicompartmental 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 unicompartmental 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 unicompartmental 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.
Published long-term clinical results on the Oxford® Knee demonstrated a 98% success rate at 10 years and 95% at 15 years and beyond, equaling the results of the most successful total knee replacements. Not all patients are candidates for Oxford® partial knee replacement.
Only an orthopaedic surgeon can determine what treatment is appropriate. Individual results of total joint replacement may vary. The life of any implant will depend on your weight, age, activity level, and other factors.
The Joint Replacement Center at Unity Hospital will host a free seminar for those who want to learn more about minimally invasive knee replacement surgery. The seminar will be held on Wednesday, January 16, 2008 from 6:30 p.m. - 7:30 p.m. at Sweden Senior Center,133 State St., Brockport. Presented by Mark Stenclik, M.D., the seminar will provide details about partial knee surgery, the advantages and disadvantages of partial knee replacement, , and who is a candidate for the surgery. The seminar is free and open to the public. It is highly recommended for those who have severe arthritis of the knee and have tried non-surgical treatments such as pain management, cortisone injections, strengthening exercises and weight loss.
