Aims and objectives: To examine the development and impact of a multidisciplinary preparation clinic for patients undergoing total knee replacement (TKR) surgery. Background: There is evidence to suggest that patients’ preoperative characteristics such as pain and mental state impact the long term results of TKR surgery. Preparation sessions may help in identifying and working with those patients whose preoperative status could reduce the benefits of surgery. Design: Action research. Method: Actions cycles were carried out to develop an information booklet and multidisciplinary Knee Clinic at an acute Trust in outer London, UK. A sample (n = 23) of patients was recruited to test changes as they were implemented. Results: The Knee Clinic involved nurse practitioners, occupational therapists, physiotherapists and service users (patients recovered from TKR surgery). Elements of physical and social assessment and interventions were carried out using a Social Cognitive Theory framework. Patients reported they benefitted from the information booklet and attendance at the Knee Clinic. Conclusion: A structured pre-operative information and assessment clinic can be developed using a Social Cognitive Theory framework for the benefit of patients. Further studies are required to examine and utilise psychological assessment of patients at such clinics.
