| Scientific title | The Warwick patellofemoral arthroplasty trial: a randomised clinical trial of total knee arthroplasty versus patellofemoral arthroplasty in patients with severe arthritis of the patellofemoral joint |
| Study objectives | The objective of the study is to recruit 64 patients who are eligible for patellofemoral arthroplasty (PFA) and randomly assign these patients to either PFA or total knee arthroplasty (TKA). The aims of the study are: 1. To quantify and draw inferences on observed differences in knee function for PFA and TKA at one-year post-operatively 2. To determine the complication rate of PFA versus TKA at one-year post-operatively 3. To investigate the cost effectiveness of PFA versus TKA On 04/08/2011 the overall trial end date for this trial was extended from 31/12/2011 to 30/04/2013 to allow the team to achieve their target recruitment level. |
| Ethics approval(s) | Coventry Research Ethics Committee, 03/03/2009, ref: 09/H1210/9 |
| Health condition(s) or problem(s) studied | Patellofemoral osteoarthritis |
| Intervention | All potential participants for this study will be identified by Orthopaedic Consultants in the arthroplasty clinics. Eligible patients will be randomised in a 1:1 allocation to a TKA or PFA. The patients allocated to TKA will have all of the surfaces of their knee joint replaced. The patients allocated to PFA will only have their patellofemoral articulation replaced. Both forms of treatment are well-established, but the exact details of the surgery will be left to the discretion of the surgeon in this pragmatic trial. The follow-up for both arms of the study will be equal: 12 months.
