Question special

It is well-established that an elevated BMI is associated with an increased risk of knee OA. The two groups shared similar patient characteristics, including high BMI. I would be interested to see if a higher BMI was associated with poorer primary and secondary outcomes in either group, but especially in the surgical group . If so, this raises a question regarding the pre-operative discussion on risks and benefits. Should a patient with knee OA and a certain BMI threshold be advised against surgical intervention due to poorer outcomes and the potential higher risk (anticipating more medical comorbidities)?
