Calipered Kinematically aligned Total Knee Arthroplasty E-Book

G. Daxton Steele, Stefano A. Bini, Stephen M. Howell

Description

Calipered kinematic alignment was proposed by Dr. Stephen M. Howell to enable the accurate and individualized placement of total knee components coincident within ± 0.5 mm of the patient’s pre-arthritic alignment. The aim was to restore the patient's native joint kinematics and thereby address the well documented 20% dissatisfaction when total knee replacement is performed using traditional, or mechanical alignment techniques.

With Dr. Stefano A. Bini and Dr. G. Daxton Steele as co-editors, Dr. Howell has curated an international team of expert surgeons and engineers to discuss various aspects of the calipered knee alignment technique in short, concise, and well-illustrated chapters. Each author provides clear, practical guidance for adopting and implementing calipered kinematic alignment covering manual, patient-specific, navigated, and robotic techniques. Chapters on component design tailored explicitly for kinematic alignment and showing the close relationship between knee biomechanics and the kinematically aligned TKA help the surgeon manage complex challenges associated with deformity and post-operative complications.

Following the introduction of the calipered kinematic alignment technique for total knee arthroplasty, many international studies have shown consistently better patient satisfaction than the traditional mechanical alignment technique. Better function and high long-term implant survival have catalyzed a paradigm shift in total knee replacement philosophy that is being embraced by orthopedic surgeons and innovative implant companies around the world with excellent results.

Calipered Kinematically Aligned Knee Arthroplasty is the definitive textbook on the subject and features:

• Thorough explanations of how the calipered kinematic alignment technique for total knee arthroplasty accurately sets total knee components coincident with the patient’s pre-arthritic alignment and coaligned with the three rotational axes of the native knee.
• A personalized approach to total knee surgery designed to reconstitute the patient’s native biomechanics in contrast with mechanical alignment that place all patients in the same standard alignment regardless of their constitutional anatomy.
• Detailed and well-illustrated descriptions of manual, navigated, robotic and patient-specific guide techniques that confirm kinematic alignment with a caliper.
• Clinical photos, radiographs, and line art throughout the book as well as helpful online technique videos.
• Key focus topics such as managing complex deformities, the expected post-operative recovery, and future trends in kinematic alignment.
• The shared experience and knowledge of international pioneers in the field.
• An emphasis on a personalized surgical philosophy which enables same-day discharge, reduces pain and opioid use, and promotes quicker recovery, better function, and a more natural feeling knee.

Preface
“Through the looking-glass” refers to the Lewis Carroll novel (i.e., the sequel to Alice in Wonderland ) where Alice crosses over into a “bizarre universe” when she enters the flipped world on the other side of a mirror. The phrase implies unpredictable and strange happenings, a poignant metaphor for the mechanical alignment (MA) total knee arthroplasty (TKA) surgeon’s initial confrontation with kinematic alignment (KA)!
Interest in calipered KA TKA is justifiably growing because most randomized trials show clinical outcomes are better, and registry and case series analyses show implant survival is comparable or better than MA, with a negligible risk of varus tibial component failure and comparable risk of patellofemoral complications at 7 to 10 years. KA is “personalized” and three-dimensional; MA is “one approach fits all” in the coronal plane.
Calipered KA is defined as the setting of the femoral and tibial components to restore the patient’s prearthritic joint lines without the release of ligaments, including the posterior cruciate ligament. Resurfacing the knee closely coaligns the components’ axes with the three kinematic axes of the native (i.e., healthy) knee, thereby preserving the posterior cruciate, collateral, and retinacular ligaments’ resting lengths, which reduces the risk of kinematic conflict between the components and soft tissues.
The surgeon uses caliper measurements of bone resections to confirm that the varus-valgus and internal-external orientations and proximal-distal and anterior-posterior positions of the femoral component are coincident within ± 0.5 mm of the prearthritic joint lines. The fine-tuning of the varus-valgus and posterior slope of the tibial cut to match the patient’s prearthritic slope creates a tight rectangular space in extension and balances the knee. These steps restore the tibial compartment forces of the native knee without ligament release, a target that compartment force studies of mechanical, functional, and restricted kinematic alignment have not achieved, even after the release of healthy ligaments.
The MA surgeon learns to “see” the knee differently, operating in the “bizarre universe” of KA. No longer are components set to the MA targets of the femoral head and ankle, the transepicondylar axis and Whiteside’s line, and a fixed posterior slope. The need for releasing ligaments disappears. Contracted and stretched ligaments are strikingly rare, even in the most deformed knees. Correction of severe varus and valgus deformities becomes surprisingly straightforward, and flexion contractures readily resolve by releasing the posterior capsule.
The calipered KA surgeon incorporates the dentist’s technique of assessing surface relationships inside the mouth to three-dimensionally fit a crown on a worn tooth without referring to a preoperative image. Similarly, the surgeon opens the knee, assesses the cartilage wear on the distal femur, sets the femoral resections’ thickness compensating for cartilage loss at 0 and 90 degrees, cuts the tibia to restore a rectangular extension space, records the resection thicknesses in their operative note, and achieves a “personalized” approach. They do not consider the tibial component is set in “varus or valgus,” because restoring the patient’s prearthritic joint line is the target. The postoperative radiographic expectation is that component alignment matches the contralateral knee’s joint lines and limb alignment within 2 to 3 degrees when the paired femora and ti
