Dr. Wassaf and KristiAdvancements in technology for orthopedic surgery has reduced complications and enhanced the recovery experience for patients. Kristi Wicker knows this all too well. She had knee replacement surgery 12 years ago at the MemorialCare Joint Replacement Center at Long Beach Medical Center. When pain in her other knee became unbearable, she chose to return to the MemorialCare Joint Replacement Center because of its expert physicians and use of the most advanced technologies.

In fact, Kristi was the 1,000 patient to have a joint replacement performed by Andrew Wassef, M.D., medical director, MemorialCare Joint Replacement Center at Long Beach Medical Center. This milestone procedure performed by Dr. Wassef puts him in the top 3% for number of Mako knee replacement surgeries performed in the nation, according to Stryker, the manufacturer of Mako™ SmartRobotics.

Mako SmartRoboticsTM is a unique technology that provides a 3D model of a patient’s unique anatomy to assist surgeons in pre-planning and precise placement of a patient’s joint implants. For Kristi, her left leg was beginning to bow out, away from her right knee due to the pain she was experiencing. This formation was unique to Kristi, and by using this technology Dr. Wassef was able to see the formation and keep an eye on it when they went into surgery.

Being able to see how the knee is sitting before and during surgery allows for the precise placement of Kristi’s new joint. This ensured that when Kristi recovered, it matched her anatomy and rectified the bowing that was happening.

Because of the 3D image that Dr. Wassef captured before surgery, he knew exactly where to remove the damaged joint and used Mako SmartRoboticsTM to help guide him. When it came time to insert the replacement, he was able to easily place it accurately forming to her unique anatomy.

Just a few hours after surgery, Kristi was up and walking the halls of the Joint Replacement Center and went home the next day – virtually pain free.

When I had my knee replacement done 12 years ago it was amazing. I have not felt pain on my right knee since. So, when it was time for me to get my left knee done, I knew I had to come back to Long Beach Medical Center. And Dr. Wassef is the best. He and his team walked me through the process and my new knee feels spectacular! I am so happy I had it replaced.

Kristi is an incredible patient, and she has been doing really well in recovery. When she and I met, she was sharing how she and her husband are planning to travel once she has her new knee. Now, that she has it, I don’t think anyone will be able to stop her from all the adventures she’s planning. I’m just happy I was able to help her.
