Clinical Trial Summary

The intention is to explore whether there are factors which help us to understand why some patient outcomes are not successful and identify prediction factors for progression. It will also assess the available outcomes pre- and post-surgery may explore prediction tools for good/poor progression and improve the patient's selection, patient preparation or timing for surgery.

The focus of this project is exploring outcomes post-primary total knee arthroplasty (TKA) using the available pre/post-operative Oxford Knee Score (OKS), University of California Los Angeles (UCLA) Activity Score, EQ-5D General Health Questionnaire, Visual Analogue (VAS) for pain, age and smoking status data, and correlations between these data and post operation patient satisfaction.

Description:

Knee osteoarthritis (OA) is a major cause of disability around the world; it is the most common chronic condition in primary care in the UK. By 2030 it is predicted to be the greatest cause of disability in the general population. An effective end-stage treatment for knee OA is knee-replacement surgery.

In England and Wales, the number of knee-replacement procedures recorded by the National Joint Registry in 2013 was 91,703, which represents an increase of 0.9 % over 2012. The data analysis by the National Joint Registry and the Office of National Statistics suggests that, by 2030, primary TKAs will increase by 117% from the 2012 level. Subsequently, TKA revision surgeries are expected to increase incrementally by 332%.

Post-TKA, 75-85% of patients report satisfaction with surgery outcomes, while the remaining 15-25% are dissatisfied. Total knee arthroplasty's success has traditionally been evaluated from the surgeon's perspective, e.g. the presence of surgical complications or implant survival. This is gradually changing to involve the patient in measuring health outcomes and decision-making processes. Patient-reported outcome measures (PROMs) have evolved to explore patient perspectives by monitoring the quality of care in health organizations and conducting clinical trial outcomes. National Health Service used PROMs to measures health gain in patients undergoing hip replacement, knee replacement, varicose vein and groin hernia surgery in England, based on responses to questionnaires before and after surgery.

This retrospective cohort study will investigate outcomes 1 and 3 years post-TKA, and factors that may predict good/poor progression based on previously gathered data, which may minimize the effect of prospective data collection bias. The study will explore accurate prediction factors of post-TKA satisfaction at Stockport NHS Foundation Trust operates at Stepping Hill Hospital which is a busy District General Hospital, with a large orthopaedic department. Outcome following knee replacement surgery is closely monitored and matches the best performing units in the UK. Potentially, reliable outcome prediction could, however, improve patient selection for surgery, as appropriate timing for surgery depends on patient symptoms and efficient patient preparation for surgery if it is to be cost-effective. Accurate preoperative prediction is crucial to minimize the potential for unrealistic expectations which may improve their satisfaction.

• All individuals have previously consented to give access to their data for research studies.

• All patients' records prospectively gathered data spanning more than 3 years will be reviewed, if they were scheduled for primary unilateral TKA for end-stage knee osteoarthritis and were in a stable and controlled medical condition at Stepping Hill Hospital.
