ARTIFICIAL KNEE

There are times when a full cadaver knee is not feasible or necessary. The EORL Artificial Knee is a sophisticated facsimile of an actual knee. It interfaces with the EORL cadaver table and recreates a full lower extremity complete with the boney and ligament abnormalities of a diseased (varus or valgus) knee. It has an active quads mechanism, realistic patellofemoral mechanics, a joint capsule, osteophytes, erosions, and many other features of real knees.

The surgeon using this model gets the real feel of operating within the confines of soft-tissues, learns the accurate placement of retractors, management of soft-tissues, and utilization of knee instruments. Because the model utilizes the EORL cadaver table, computer navigation can be fully reproduced. The EORL artificial knee is literally the next-best thing to an actual cadaver leg.

FIGURE 1: The artificial knee includes a full length hip to ankle specimen complete with anatomically correct muscles, capsule, extensor mechanism, and collateral ligaments. The collateral ligaments and extensor mechanism can be tensioned selectively to recreate the diseased knee.

FIGURE 2:The skin layer recreates the feeling of operating through a limited space. 

Figure 3: The capsule, patella, extensor mechanism complete the deep soft-tissue anatomy and allow specific surgical approaches such as the mini-mid vastus approach to be demonstrated.

Figure 4 and 5: The deep anatomy includes the ACL, PCL, capsular attachments and boney landmarks that realistically reproduce a diseased knee.  Notice the medial osteophyte and tibial erosion in this varus knee with medial compartment osteoarthritis.

Figure 6: The EORL Artificial Knee and EORL Hip Clamp (patent pending) recreate the full surgical experience including the surgical approach, bone resections, soft-tissue management, and computer navigation of knee surgery.
