Abstract

Background: Osteoarthritis of the knee is a common condition that is expected to rise in the next two decades leading to an associated increase in total knee replacement (TKR) surgery. Although there is little debate regarding the safety and efficacy of modern TKR, up to 20% of patients report poor functional outcomes following surgery. This study will investigate the functional outcome of two TKR; the JOURNEY II Bi Cruciate Stabilised knee, a newer prosthesis designed to provide guided motion and improve knee kinematics by more closely approximating a normal knee and the GENESIS II, a proven existing design. Aim: To compare the change in patient reported outcome scores of the JOURNEY II BCS and the GENESIS II from pre-operation to six months post-operation. Methods: CAPAbility is a pragmatic, blinded, two-arm parallel, randomised controlled trial recruiting patients with primary osteoarthritis due to have unilateral TKR surgery across two UK hospitals. Eligible participants (n=80) will be randomly allocated to receive either the JOURNEY II or the GENESIS II BCS knee prosthesis. Baseline measures will be taken prior to surgery. Patients will be followed at one week, six to eight weeks and six months post-operatively. Primary outcome is the Oxford Knee Score (OKS) at six months post-operatively. Secondary outcomes include: other patient-reported outcome measures (PROMs), biomechanical, radiological (computerised tomography, (CT)), clinical efficacy and safety outcomes. An embedded qualitative study will also investigate patients’ perspectives via interview pre- and post-surgery on variables known to affect the outcome of TKR surgery. A sub-sample (n=30) will have additional in-depth interviews to explore themes identified. The surgeons’ perspectives on the operation will be investigated by a group interview after all participants have undergone surgery. Discussion: This trial will evaluate two generations of TKR using PROMS, kinematic and radiological analyses and qualitative outcomes from the patient perspective.
