Summary

Why offer an MPK trial fit?

Microprocessor knee (MPK) trial fittings provide an effective way to evaluate whether an MPK is appropriate for an individual patient before a long-term decision is made.

For O&P professionals, trial fittings offer valuable insight into how a patient responds to improved stability, gait control, and adaptive support in everyday situations.

The patients will have a chance to feel the differences in stability, confidence, terrain adaptation, and energy use in their daily environments. This boosts engagement, supports realistic goal‑setting, and leads to safer mobility and a better quality of life.

  • Assess potential MPK benefits in real-life situations

  • Support confident clinical decisions

  • Optimize component selection, fit, and alignment

  • Increase patient engagement throughout rehabilitation

How does the process work?

  • Order trial components via customer support or reach out via our online form on this website

  • Fit and program during initial appointment (~60–90 min)

  • Trial on existing socket, if suitable

  • Define trial duration (hours to weeks)

  • Return components after evaluation
