Fig. 2From: Macroscopic and microscopic assessments of the glenohumeral and subacromial synovitis in rotator cuff diseaseMacroscopic 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, 2.0Back to article page
