MIS: ODYSSEY™ Tissue Preserving Initiative for Knee Surgery

ODYSSEY™ MIS instrumentation enables a surgeon to perform a minimally-invasive and tissue-sparing surgical technique. This technique is designed to return patients to their normal, active life faster.

The ADVANCE® Medial-Pivot Total Knee and ADVANCE® Double-High Knee System implants provide more natural function and have been shown to be preferred by 80% of patients when compared to other knee systems. When combined with these implants, ODYSSEY™ MIS instruments may significantly improve the results of total knee arthroplasty.

ODYSSEY™ MIS Knee instrumentation was developed to be as reproducible and intuitive as classic total knee instrumentation. By design, the instrumentation's reduced size and anatomical shape make it ideally suited for MIS procedures facilitating implantation of the ADVANCE® Double-High and Medial-Pivot Knee systems, which offer solid clinical history and exemplary patient results.

What Is MIS?

Ideally, an MIS surgical approach does not evert the patella or resect the quadriceps muscle or quadriceps tendon. It does not necessarily involve a smaller, 4 to 6-inch skin incision. Theoretically, by not disturbing the knee extensor mechanism, patients experience faster recovery and less postoperative pain.

What Is the Surgical Approach?

The surgical approaches utilized for MIS may be the mid-vastus split, the subvastus, or the median parapatellar approach. Most of these approaches have long clinical histories in standard TKA but have been adapted for MIS by reducing the length of the incision.

What Does the Data Show?

Preliminary results have consistently shown that patients experience decreased blood loss, less pain, and earlier range of motion.

What Do I Need to Know?

TKA is one of the most reproducible and effective procedures in orthopaedics due to established foundations in both instrument and implant design. Instrumentation must facilitate accurate alignment, ligamentous balancing, and precision resections. Implants must be anatomic, provide low polyethylene wear, and remain fixed over time. When choosing an MIS knee system, all of these factors must be taken into account.
