Macroscopic and microscopic findings of synovitis in the glenohumeral joint (upper row) and subacromial space (lower row) with arthroscopy. a The anterior synovium in the glenohumeral joint. The macroscopic assessment was villous hypertrophy, 1; hyperemia, 1; density, 1; grade, 2. b The posterior synovium in the glenohumeral joint. Villous hypertrophy, 1; hyperemia, 1; density, 1; grade 2. c The inferior synovium in the glenohumeral joint. Villous hypertrophy, 0; hyperemia, 0; density, 0; grade, 0. d The microscopic findings of the anterior synovium in the glenohumeral joint. The macroscopic assessment was villous hypertrophy, 1; hyperemia, 1; density, 1; grade 2. The microscopic assessments were the Østergaard grade, 1.7; the Loeuille grade, 1.7; the modified Krenn grade, 2.0; the Scanzello grade, 2.0. e The anterior synovium in the subacromial space. The macroscopic assessment was villous hypertrophy, 2; hyperemia, 0; density, 1; grade, 2. f The posterior synovium in the subacromial space. Villous hypertrophy, 0; hyperemia, 0; density, 0; grade 0. g The lateral synovium in the subacromial space. Villous hypertrophy, 2; hyperemia, 0; density, 0; grade, 1. h The microscopic finding of the lateral synovium in the subacromial space. The macroscopic assessment was villous hypertrophy, 2; hyperemia, 0; density, 1; grade 2. The microscopic assessments were the Østergaard grade, 1.3; the Loeuille grade, 1.2; the modified Krenn grade, 2.0; the Scanzello grade, 2.0
