VIDEO VIGNETTE: The Surgical Technique for Bicruciate Knees
Conventional total knee arthroplasty (TKA) implant designs have limitations in their ability to recreate the normal motion of the knee, which can result in less-than-satisfied patients.
One of the issues, says Steven B. Haas, MD, MPH, from Hospital for Special Surgery in New York, is the abnormal kinematics caused by the loss of the cruciate ligaments and alterations in the surface anatomy after TKA.
A possible solution is the use of bicruciate knee designs, which Dr. Haas reviewed during ICJR’s instructional course on joint replacement surgery for the 9th Congress of the Chinese Academy of Orthopaedic Surgeons.
Dr. Haas, who has been involved in designing a commercially available bicruciate implant, said the goals of these implants are it to:
- Reproduce the normal anatomic contours of the knee and cruciate function
- Restore kinematic patterns and improve function
Dr. Haas showed a lengthy video of a primary TKA with a bicruciate substituting TKA, offering his tips, tricks, and surgical pearls for the technique involved in using this type of implant.
