Study finds, Contracted joint capsule affects labral and cho
Intra-articular pathologies, such as labral and chondral lesions, are common in patients with frozen shoulder. This study evaluated the correlations between the range of motion and labral and chondral lesions in patients with frozen shoulder and investigated their pathophysiologies.

In total, 125 individuals who underwent arthroscopic pan-capsular release were included in the study. The range of motion was measured using scapular fixation and true glenohumeral motion under general anaesthesia. The American Shoulder and Elbow Surgeons Shoulder score and the Shoulder Rating Scale score of the University of California, Los Angeles were used to compare intra-articular pathologies.

--More than 80% of patients with frozen shoulder had labral pathologies, and nearly half of them had chondral pathologies.

--Labral lesions extending to the anterior rim of the glenoid had a greater range of motion and the greatest total American Shoulder and Elbow Surgeons Shoulder score.

--More severe chondral lesions had a lesser range of motion, but presented the greatest function scores and the lowest strength scores.

--The pain scores of the American Shoulder and Elbow Surgeons Shoulder score and the Shoulder Rating Scale were not correlated with the degree of these pathologies. The traction force affected the labrum during true range of motion, and the compression force occurred on the articular cartilage during internal rotation at 90° of forward flexion during diagnostic arthroscopy.

Finally, in patients with frozen shoulder, labral and chondral lesions are frequent. The adherence to the capsulabral complex has led to a limited variety of movement and labral and chondral diseases. Diagnostic movement arthroscopy is an important way in which individuals who have a frozen shoulder can reproduce intraarticular etiology.
