Adverse events — posted to ClinicalTrials.gov
Time frame: Adverse events were monitored for each participant from the time of enrolment (baseline) through to their final study visit (2 years post-operative)..
Reporting threshold: 5%.
Adverse-event reports describe events observed during the trial — not all are caused by the drug.
The objective of this study is to compare clinical and radiological outcomes in robotic-arm assisted TKA using mechanical alignment (MA TKA) versus robotic-arm assisted TKA with functional alignment (FA TKA).
These outcomes will be used to determine if patient recovery is better with functionally aligned Mako robotic-assisted total knee arthroplasty (FA TKA) or mechanically aligned Mako robotic-assisted total knee arthroplasty (MA TKA).
