Summary
|
Contemporary total knee arthroplasty (TKA) provides reliable pain relief and restoration of moderate function for patients suffering from severe joint degeneration. Outcomes are typically good, but patients sometimes lack adequate range of motion and strength. Many studies have demonstrated a link between prosthesis design and patient function 1,2,3 and newer TKA designs attempt to incorporate these findings to help patients quickly regain and improve their knee function after surgery.
Based on in vivo kinematic studies and retrieved implant analysis, the 3D Knee prosthesis (Encore Medical, Austin, TX) was designed with the goals of providing better patient strength, improved range of motion, and enhanced durability (Figure 1). This report summarizes early clinical and functional outcomes of patients receiving the 3D Knee and characterizes durability on retrieved prostheses.
