INTRODUCTION: Hospital-acquired infection is still one of the health problems in the world that require infection control and prevention efforts, especially nurses' hand washing compliance. Various strategies and efforts to improve handwashing compliance include educational approaches, motivation and improvement of the health care system, one of which is through the use of The Theory Of Planned Behaviour application in solving handwashing compliance.
MATERIALS AND METHODS: Quantitative research with a survey approach and observation of hand washing compliance of all nurses N = 321 with a sample of n = 178 nurses. The research variables studied consisted of intention, discipline, self-assessment, opportunity compliance and implementation of the nurse's hand washing. Nurse handwashing compliance observations were made by Infection Prevention Control Link Nurse (IPCN) committee. Data analysis using structural equation modelling (SEM) with smart partial least square (SmartPLS 3.0) application.
RESULTS: The nurse's intention to apply the theory of planned behaviour has no significant effect on the implementation of hand washing with path coefficients of 0.104 and p-value 0.221 > 0.05. The effect of nurses' intentions on the implementation of nurse hand washing through discipline is significant with a value of variance accounted for (VAF) 0.8043 or 80.43 % of nurse discipline is a complete mediation variable.
CONCLUSION: Discipline as a complete meditation variable in the application of the theory of planned behaviour in the compliance of nurses' hand washing five moments six steps. Nurses are expected to continuously improve their discipline independently or be assisted by training activities facilitated by the hospital.

Introduction: Periprosthetic fractures are a devastating complication following total knee arthroplasty. Little is known about the effect of mechanical factors on the incidence of periprosthetic fractures. The aim of this study was to examine the correlation between pre-operative mechanical factors, like side of surgery, coronal alignment and pre-operative range of motion and intra-operative factors, and the incidence of a periprosthetic fracture, following primary total knee arthroplasty (TKA). Materials and Methods: Forty-two patients with periprosthetic fractures (PPF) after primary TKA were identified from our hospital arthroplasty registry. These patients were matched two-to-one for gender and age at primary knee arthroplasty to 84 patients without PPF. The incidence of periprosthetic fracture with regards to laterality, coronal alignment and pre-operative range of motion was analysed. Intra-operative factors like implant type, patellar resurfacing and notching were also analysed using logistic regression. Results: Coronal alignment, pre-operative range of motion and patella resurfacing were not significant predictors of periprosthetic fractures. Anterior femoral notching was found to be significantly higher in the fracture group with an odds ratio of 17. Left sided surgery was also significantly higher in the periprosthetic fracture group. Conclusion: Periprosthetic fractures are 17 times more likely to occur in a knee with anterior femoral notching. Preoperative factors like coronal alignment and poor preoperative range of motion do not seem to increase the risk of periprosthetic fractures after TKA.
