Background: Scapular kinesia is an important component of glenohumeral rhythm and shoulder stability. No studies have evaluated scapular dyskinesis and its relationship to shoulder proprioception in patients who have undergone arthroscopic Bankart repair (ABR). Purpose: To investigate scapular dyskinesis, proprioception, and functional level after ABR. Study Design: Cohort study; Level of evidence, 3. Methods: This study included 13 male patients who underwent ABR (ABR group; mean age, 30 years; range, 24-36 years) and 13 sex- and age-matched healthy individuals (control group). The age, height, weight, and dominant side of all participants were collected. Scapular dyskinesis was evaluated using the lateral scapular slide test and the scapular dyskinesis test; proprioception was measured by the active angle reproduction test using a smartphone goniometer application, and functional level was assessed using the upper-quarter Y-balance test for dynamic stability as well as the Rowe score and Walch-Duplay score for quality of life and return to activities of daily living. Results: The presence of static scapular dyskinesis in the neutral position, at 45 degrees of abduction, and at 90 degrees of abduction as well as the presence of dynamic scapular dyskinesis was higher in the ABR group compared with the control group (P <= .04 for all). Shoulder joint position sense (absolute error) at 40 degrees and 100 degrees of shoulder elevation and shoulder functional level according to the Rowe score were worse in the ABR patients compared with the healthy controls (P <= .02 for all). Dynamic scapular dyskinesis was negatively related to shoulder joint position sense at 40 degrees of shoulder elevation (r = -0.64; P = .01). Static scapular movement as measured on the lateral scapular slide test was moderately related to the Rowe score (r = 0.58; P = .03). Conclusion: Scapular kinematics and proprioception should be evaluated after ABR. Treatment approaches to improve scapular control and proprioceptive sense should be included in the rehabilitation program for patients after ABR.
