Abstract
BACKGROUND: Obtaining patient satisfaction is a key goal of surgical treatment. It was the purpose of this study to identify pre-, peri- and postoperative factors determining patient satisfaction after shoulder surgery, quantify their relative importance and thereby allow the surgeon to focus on parameters, which will influence patient satisfaction. METHODS: We retrospectively reviewed 505 patients, who underwent either rotator cuff repair (n = 216) or total shoulder arthroplasty (n = 289). We examined 21 patient-specific and socio-demographic parameters as well as 31 values of the Constant-Score with regard to their impact on patient satisfaction. RESULTS: In the univariable analysis higher patient satisfaction was correlated with higher age, private health insurance, light physical work, retirement, primary surgery, non-smoking, absence of chronic alcohol abuse, absence of peri- or postoperative complications, operation performed by the medical director as well as various Constant Score sub-values (p < 0.05). In the multivariable analysis absence of peri- or postoperative complications (p = 0.008), little postoperative pain (p = 0.0001), a large range of postoperative active abduction (p = 0.05) and a high postoperative subjective shoulder value (p = 0.0001) were identified as independent prognostic factors for high satisfaction. CONCLUSION: After reconstructive shoulder surgery particular attention should be paid to prevention of complications, excellent perioperative pain control and restoration of abduction during rehabilitation. This study is first step towards a preoperative prediction model of a subjectively successful surgery as well as a tool to exclude irrelevant parameters in clinical routine.
