We never lead with surgery on a partial-thickness rotator cuff tear, and we didn't here. The first step was a twelve-week course of physical therapy focused on posterior capsule mobility, scapular stabilization, and graded rotator cuff strengthening through her pain-free range. She was disciplined about it — she had a fifteen-minute home program she did every morning before coffee, and she didn't miss her supervised sessions.
Around week six, when her overhead pain was still limiting her at night and at the pool wall, we offered a single subacromial corticosteroid injection. The goal of the injection was twofold: a diagnostic confirmation that the pain was coming from the bursa and tendon (which it was — she got near-complete relief for about ten days), and a therapeutic window for her PT to make progress. The window closed faster than we hoped. By week twelve she had real strength gains on the exam but her functional ceiling had not moved — she still could not freestyle without pain, and she still woke up at night. We sat down together and laid out the full menu — keep grinding on conservative care, accept a permanently lower activity ceiling, or repair the tendon. She told us she had no intention of being a breaststroke-only swimmer for the rest of her life.
