Elevated levels of TNF-α, IL-1β and IL-6 in the synovial tissue of patients with labral tear: A comparative study with hip osteoarthritis

Labral tear can be the initiating factor in the onset of hip osteoarthritis (HOA). However, the physiopathology of labral tear is not fully understood. Our aim was to compare synovial tissue inflammatory cytokine levels between patients with labral tear and late-stage HOA.
