Bryn Mawr Hospital is First on East Coast to Offer ``Custom Fit'' Total Knee Replacement with OtisKnee

Groundbreaking New Technology Allows Surgeons to Customize Implant Size and Fit for Each Individual Patient

BRYN MAWR, Pa.--(BUSINESS WIRE)--As part of its ongoing commitment to bring breakthrough medical advancements to residents of the greater Philadelphia area, Bryn Mawr Hospital has become the first institution on the East Coast to offer custom fit total knee replacement with OtisKnee. Using OtisKnee, orthopedic surgeons can for the first time precisely match the size and placement of the implant to the patients unique and normal (non-arthritic) knee anatomy.

“I did a deep knee bend at my niece’s wedding just six weeks after surgery”

Developed by California-based OtisMed Corporation, this new custom fit approach with OtisKnee enables surgeons to preserve more bone and ligaments, allowing for better implant fit and alignment. OtisKnee physicians and patients have reported a quicker and less painful recovery, increased range of motion, a more natural feeling knee, and greater ease in performing normal living activities such as golfing, biking and gardening.

In my experience performing more than 100 OtisKnee procedures at the Bryn Mawr Hospital Orthopedic Center, patient satisfaction is higher than Ive seen in my previous 19 years of practice, said Joseph Vernace, M.D., the first local orthopedic surgeon to use the OtisKnee technique. Ive seen recovery times reduced significantly, with most patients walking up and down stairs in just six weeks. Also, my patients tell me their knees feel much more natural and normal.

The custom fit total knee replacement with OtisKnee is achieved in a few steps, before and during surgery. Prior to surgery, an MRI is performed to take very precise measurements of the patients arthritic knee. Second, proprietary computer software creates a 3-D image of that knee, and then virtually corrects the deformity to return the knee to its pre-arthritic state. Third, a computerized 3-D image of the implant to be used in the patients surgery is then Shape-Matched to the anatomically correct virtual knee model. This helps determine the correct implant size and placement, based on the patients own normal (non-arthritic) knee anatomy. Last, using all of this information, special cutting guides are created for the surgeon to use during the procedure. These patient-specific cutting guides, which are accurate to within a few millimeters, indicate to the surgeon exactly where to make bone cuts so that the knee replacement is customized for the individual patient.

I did a deep knee bend at my nieces wedding just six weeks after surgery, said Terry Gibbs of King of Prussia, Penn., who received a custom fit knee replacement on his left knee in September 2006 after undergoing traditional knee replacement on his right knee in 2001. In my opinion, theres no comparison between OtisKnee and the old technique. The custom fit approach is a great step forward.
