Group 1 underwent a sham procedure with no treatment (sham controls). Group 2 underwent placement of a metal clip in bilateral shoulders to induce impingement on the rotator cuff but received no further treatment. All mice receiving treatments (groups 3-6) underwent bilateral clip impingement surgery on day 0. On day 21, subacromial injections of CSI, AK, or A2M were performed, and LOS was administered via drinking water. All mice were sacrificed at 6 weeks after the initial impingement surgery. The supraspinatus tendons and muscles were harvested. Histology, biomechanical testing, flow cytometry, gene expression, and gait analysis were performed.
