Although results of tibial component fixation with cement in total knee arthroplasty TKA have been good, [ 1 — 14 ] the ideal technique of cementing is still debated [ 15 — 18 ]. System Specification Guide and Product Catalog. For example, one of the most widely cited studies critical of surface cementation exhibited high failure rates with a macrotextured waffle-pattern tibial base plate [ 31 ].
Zimmer Biomet offers a wide variety of solutions that address fixation, constraint, soft tissue and boney defect management challenges that are often encountered during revision knee arthroplasty. Provides options to enhance intraoperative performance — Available in a variety of tray sizes, thickness, and articulation to address many soft tissue scenarios: This material is intended for health care professionals.

If a properly designed implant is used in conjunction with proper surgical technique, early implant stability can be achieved. This website may set one or more cookies on your computer.

After the cut surface of the tibia was checked for proper alignment, the tibia was broached with a cruciform tibial punch slightly undersized from the real tibial keel to achieve true press fit. Clinical results were graded according to the Knee Society Clinical Rating System by a member of the research team other than the operating surgeon [ 26 ].

Tibial surface after preparation with drilling sclerotic bone and pulse lavage. Proximally flared patellar track accommodates varying Q-angles Extended trochlear groove maintains patella contact in flexion Rounded sagittal profile reduces soft tissue forces mid-flexion 10 proportional femoral sizes 1: Although support for the technique of surface cementation with press-fit designs of the tibial component exists in the literature, [ 2428 ] other studies have demonstrated higher failure rates with this technique [ 2029 ].

Full cementation of the tibial component cementation of the undersurface of the tibial component and stem has been advocated to improve short-term and long-term fixation of the tibial component [ 218 — 20 ]. Indexed in Science Citation Index Expanded. The benefits of the Vanguard Revision Knee System include: Patients were included in the study, if they had received a modular titanium baseplate with a cruciform keel using a surface cemented technique and had a minimum five-year followup or failure of the TKA prior to five years.
We have confirmed previous reports of good results using a surface cementation technique of the tibial component. Distribution to any other recipient is prohibited. This resulted in a final series of knees from patients.
In order to ensure adequate depth of cement penetration, a 2. Of the knees, were female and were male. Histogram demonstrating the number of patients available for followup.

For this study, the preoperative and most recent follow-up knee scores were compared, as well as documentation of the number of failures, reoperations, and complications. Bone Joint J ; 10 Suppl B: Two cases of suspected aseptic loosening of the tibial component were identified and very few knees demonstrated radiographic radiolucencies.

Mean followup was 8 biomeh, including those who failed prior to five years range, 0. Our innovations help treat patients suffering from disorders of, or injuries to, bones, joints or supporting soft tissues. Thus, we retrospectively reviewed the clinical and radiographic outcomes of consecutive primary TKAs performed with surface cemented tibial components.

Radiographs were evaluated by one of the authors according to the Knee Society Total Knee Arthroplasty Roentgenographic Evaluation and Scoring System maxlm 27 ] for radiolucent zones, femoral component flexion and valgus, tibial component slope and varus, and anatomic axis was measured on the longstanding film for overall mechanical alignment.

Cruciate Retaining CR Knee: Little data exists regarding outcomes following TKA performed with surface-cementation for the fixation of modular tibial baseplates with press-fit keels. Given the positive biomett and radiological outcomes seen in mxim series and only a small amount of complications demonstrated along with the theoretical advantages of improved proximal tibial bone density and less tibial bone loss at the time of revision, we feel that surface cementing the tibial component is a reasonable technique for consideration in total knee arthroplasty.
