Eugene Jacob, MD, orthopedic surgery, performed Baptist Hospital Northeast’s first OtisKnee® replacement surgery on Roy Lyons of Shelby County on April 21. Dr. Jacob is now one of only a handful of physicians in Kentucky doing the OtisKnee.
OtisKnee is a technique that, for the first time, allows surgeons to offer knee replacements that are custom fit to the individual. An MRI is done on the patient’s knee, then the images are sent to OtisMed in California, where a three-dimensional model of the knee is created. Using the model, surgical instruments are created to guide and assist the surgeon during the operation. This helps the surgeon better restore three rotational axes in the patient’s reconstructed knee. Because the fit is perfect for the individual, the patient’s knee joint is brought back into alignment, no soft tissue releases are required for balance, and there is less bone loss and faster healing.
According to John Whitsett of Stryker Orthopedics, the local distributor of the OtisKnee, the procedure has been performed nationwide since January 2006 and in Kentucky for about a year and a half. Results are better three months after surgery with the OtisKnee than after six months with conventional knee replacement surgery. The procedure usually takes less than an hour.
“Every time I do one of these, when I straighten the knee, it is stable and I have more confidence that the patient will do well,” said Dr. Jacob. “Patients rehab quickly, have less pain, regain range of motion quicker and have less bleeding.
“The important thing post-op is getting the proper balance for proper wear (of the joint),” Dr. Jacob explained.
Most patients stop using a cane or walker as early as two to three weeks after surgery and are able to return to activities such as driving as early as three to four weeks; gardening and golfing in six to eight weeks. With traditional knee replacement surgery, most patients are walking without a cane or walker by six weeks and return to normal activities by 12 weeks after surgery.
