MOTUS Total Joint Replacement Investigational Device Exemption Study

A multi-center (up to 20 investigational sites), prospective, non-blinded investigation of the MOTUS Total Joint Replacement (TJR) device. These data will be compared to a lumbar interbody fusion (transforaminal lumbar interbody fusion \[TLIF\] or posterior lumbar interbody fusion \[PLIF\]) control group enrolled in a separate real world evidence (RWE) study. Balance between groups will be achieved through sub classification using propensity scores by a blinded statistician.
