Deciding how to allocate scarce surgical resources is a worldwide issue. These decisions are difficult when considering procedures aimed primarily at improving functional quality of life, such as lower extremity joint replacement (LEJR) surgery, and procedures perceived as life preserving which also have impacts on physical function, such as coronary artery bypass graft (CABG) surgery. Comparing functional outcomes of these two procedures may provide further evidence to guide resource allocation decisions. We compared patient-reported functional outcomes following CABG and LEJR surgery using standardised, validated outcome metrics. A retrospective review of prospectively collected pre- and post-operative health related quality of life (SF-36) measures were conducted from 105 patients undergoing elective CABG and 105 elective LEJR surgery patients. Patients were matched based on gender and age.Background
Methods
Unidirectional mobile bearing knees (RP) were developed to optimise the tibio-femoral articulation in an effort to enhance function and reduce polyethylene wear. The self-aligning bearing should also benefit the patello-femoral joint further improving outcome. This study was designed to assess whether these potential benefits are realised in the clinical setting. A total of 352 patients undergoing a PS PFC Sigma TKR were randomly allocated to receive either a Mobile Bearing (176 knees) or a Fixed Bearing (176 knees) tibial tray. Within each group a further randomisation for patella resurfacing versus retention was included. All knees were scored using standard outcome tools (Oxford, AKSS, Patella Score) by independent nurse specialists.Introduction
