The quackery of traditional sports medicine……..
“Labral repair and biceps tenodesis are routine operations for superior labrum anterior posterior lesion of the shoulder, but evidence of their efficacy is lacking. We evaluated the effect of labral repair, biceps tenodesis and sham surgery on superior labrum anterior posterior lesions.”
“A double-blind, sham-controlled trial was conducted with 118 surgical candidates (mean age 40 years), with patient history, clinical symptoms and MRI arthrography indicating an isolated type II superior labrum anterior posterior lesion.”

Patients were randomly assigned to either labral repair (n=40), biceps tenodesis (n=39) or sham surgery (n=39) if arthroscopy revealed an isolated superior labrum anterior posterior II lesion.”

“There were no significant between-group differences at any follow-up in any outcome.”

“Similar results—no differences between groups—were found for WOSI scores. Postoperative stiffness occurred in five patients after labral repair and in four patients after tenodesis.”

“Neither labral repair nor biceps tenodesis had any significant clinical benefit over sham surgery for patients with superior labrum anterior posterior II lesions in the population studied.”
