Study summary

To compare the outcomes of patients receiving the ConforMIS custom total knee implant to the outcomes of patients who receiving an off-the-shelf total knee implant.

Hypothesis: Patient-specific, custom total knee implants manufactured from patient CT data, and implanted with CT-navigated custom instruments will show faster functional recovery, including gait and patient functional outcome scores, when compared to standard, off-the-shelf total knee components inserted with non-navigated instruments (the present standard of care in total knee surgery).

Read the detailed description

The experimental design was changed based on enrollment hurdles to be a single cohort observational study where ConforMIS patients were enrolled and followed for 6 months with 6 minute walk used as the primary outcome measure.
