Macroscopic and microscopic assessments of the glenohumeral and subacromial synovitis in rotator cuff disease

Table 1 Baseline characteristics of patients

GFDI^b	1.7 ± 0.7
Associated lesions
SLAP lesion	34 (63.0 %)
Subscapularis tear	14 (25.9 %)
Biceps tear	6 (11.1 %)

^aGFDI global fatty degeneration index, SLAP superior labrum anterior and posterior
^bThe values are given the mean and the standard deviation
^cTendon grade assesses rotator cuff quality using 3 gross tendon criteria: (1) fraying over half of the tendon thickness, (2) delamination of the supraspinatus tendon, and (3) thinning of less than half of the normal thickness. A, none of these criteria were met; B, fraying or delamination was identified; C, both fraying and delamination or thinning regardless of the other criteria
^dKellgren-Lawrence grade evaluates the radiographic severity of osteoarthritis of the knee: Grade 0, normal; grade 1, doubtful narrowing of the joint space and possible osteophyte lipping (irregular bone formation); grade 2, definite osteophytes and possible narrowing of the joint space; grade 3, multiple moderate-size osteophytes, definite narrowing of the joint space, some sclerosis, and possible deformity of bone contour; grade 4, large osteophytes, marked narrowing of the joint space, severe sclerosis, and definite deformity of bone contour
