Differences in Patients' and Surgeons' Expectations before Shoulder Stabilization Surgery.

Purpose: The primary goal of shoulder stabilization procedures is to re-establish stability and many surgeons measure the success after shoulder stabilization surgery only by the absence of re-dislocation. However, patients might also suffer from pain, loss of range of motion and strength as well as anxiety and stigmatization and therefore have other expectations from a stabilization surgery than just a stable shoulder. Purpose of this study was to analyze if surgeons know what their patients typically expect from a shoulder stabilization surgery. Furthermore, the aim was to analyze the influence of various factors on patients’ expectations. Materials and Methods: 204 patients with a diagnosis of shoulder instability scheduled for surgical treatment were included in this prospective multicentric study. Preoperatively, objective and subjective scores were obtained and patients were asked about their postoperative expectations. Additionally, 25 surgeons were interviewed with regard to what they think their patients expect from the surgery using standardized questions. Results: With regard to postoperative expectations surveyed by the Hospital for Special Surgery questionnaire (HSS), the most important goal to achieve for the patients was ‘stopping the shoulder from dislocation’, followed by ‘to improve the ability to exercise or participate in sports’ and ‘being the shoulder to be back the way it was before the issue started’. The ranking of factors for patients was ‘stability’ as the most important to achieve, followed by ‘movement’, ‘strength’, ‘pain’ and ‘cosmetics’. For surgeons, the order was ‘stability’ (p = 0.004 **), ‘movement’ (p = 0.225), ‘pain’ (p = 0.509), ‘strength’ (p = 0.007 **) and ‘cosmetics’ (p = 0.181). There was a significant difference between patients and surgeons with regard to gaining stability at the cost of movement (p = 0.001 **). Conclusion: Patients and surgeons expectations regarding outcome after surgical shoulder stabilization procedures are quite similar with limited topics of disagreement. Generally, surgeons tend to overrate the importance of stability at the costs of other factors.
