Clinical factors that affect perceived quality of life in arthroscopic reconstruction for acromioclavicular joint dislocation.

OBJECTIVE: To analyse the results of arthroscopic repair of acromioclavicular dislocation in terms of health-related quality of life.

MATERIAL AND METHOD: Prospective study of patients with acromioclavicular dislocation Rockwood grade iii-v, treated arthroscopically with a mean follow up of 25.4 months. The demographics of the series were recorded and evaluations were performed preoperatively, at 3 months and 2 years with validated questionnaires as Short Form-36 Health Survey (SF-36), visual analogue scale (VAS), The Disabilities of the Arm, Shoulder and Hand (DASH), Constant-Murley Shoulder Outcome Score (Constant) and Walch-Duplay Score (WD).

RESULTS: Twenty patients, 17 men and 3 women with a mean age of 36.1 years, were analysed. According to the classification of Rockwood, 3 patients were grade iii, 3 grade iv and 14 grade v. Functional and clinical improvement was detected in all clinical tests (SF-36, VAS and DASH) at 3 months and 2 years follow up (P<.001). The final Constant score was 95.3±2.4 and the WD was 1.8±0.62. It was not found that the health-related quality of life was affected by any variable studied except the evolution of DASH.

CONCLUSIONS: The health-related quality of life (assessed by SF-36) in patients undergoing arthroscopic repair of acromioclavicular joint dislocation grades iii-v was not influenced by gender, age, grade, displacement, handedness, evolution of the VAS, scoring of the Constant or by the WD. However, it is correlated with the evolution in the DASH score.
