A 64-year-old female presents to the clinic with a traumatic rotator cuff tear that is indicated for surgical fixation. She has a history of diabetes, hypothyroidism, and a BMI of 39 kg/m². She undergoes rotator cuff repair in the beach chair position. Intraoperatively, significant tendon retraction was encountered and the surgeon opted to convert to a mini-open procedure. Postoperatively, she complains of numbness in her anterolateral left thigh. She denies any weakness with hip flexion and does not have a foot drop. Which factor places the patient at highest risk for the complication she is experiencing?
