BYOL: Bring your own ligaments

t’s funny how things change as you age. For instance, we all reach a point where we don’t have to have the newest or best of everything – we just need something that works. You might feel that way about your car or your phone, but what about your ACL and PCL?

The ACL, or anterior cruciate ligament, and PCL, or posterior cruciate ligament, are located in your knee and are essential to natural knee movement and function. That’s why you hear about so many athletes getting a torn ACL repaired – you need those ligaments to function properly.

“These ligaments provide stability for the joint and increase the patient’s ability to perform complex movements, such as dancing, gardening or golfing,” explained Dr. Bill Bryan, a Houston Methodist orthopedic surgeon.

When you are old enough for a knee replacement, your ACL and PCL are certainly a bit worn out, but they still work, which is good enough for you. So why do surgeons remove the ACL and PCL when you have a knee replacement? Until now, they’ve not had an option.

A traditional total knee replacement requires removing the “island” of bone to which the ACL and PCL are attached. A new total knee replacement implant features a shape that protects that island of bone and saves the ligaments.

Dr. Bryan was one of 10 surgeons from across the country and the only surgeon in Houston to be selected as an early evaluator of the XP knee, made by Biomet, which features the new ligament-saving design.

“Most of my knee replacements patients are completely happy with their new knee, but some complain that they are not able to physically do everything they previously could,” Dr. Bryan said. “By saving the ligaments, this knee implant provides an improved range of motion and increases joint stability and natural movement for knee replacement patients,” Dr. Bryan said.

Dr. Bryan believes that another benefit of saving the ACL and PCL for knee replacement patients is that the ligaments will take some of the strain off the metal and plastic components of the knee replacement and help it to last longer. Most artificial knees last approximately 10 years before needing to be replaced.

“For many years, orthopedic surgeons have recognized the need for total knee replacements that save the ligaments,” Dr. Bryan said. “Now that technology and design have caught up with us, patients can now get a total knee replacement that works and feels a lot like a normal knee.”
