Abstract
PURPOSE: To evaluate the midterm results of partial rotator cuff repair using the Constant score and the acromiohumeral radiographic measurement.
METHODS: Thirty-eight patients with a mean age of 65 years and a large retracted rotator cuff tear (at least 2 tendons) were included in the study. Patients underwent clinical examination, standard radiography, and isometric strength testing at a mean follow-up of 47 months. The rotator cuff tears were classified as posterosuperior, anterosuperior, or global tears (≥3 tendons), and an arthroscopic partial repair was performed.
RESULTS: The mean Constant score significantly increased from 56 points before surgery to 71 points after surgery (P = .041); the mean age- and sex-adjusted Constant score significantly improved from 63% to 90% at a mean follow-up of 47 months after arthroscopic partial rotator cuff repair (P = .003); and the subcategories pain and activity significantly improved (P = .001, P = .014, respectively). The active range of motion improved from 133° of flexion and 111° of abduction before surgery to 163° of forward flexion and 156° of abduction after surgery (P < .001). However, the active range of external rotation decreased from 44° before surgery to
