This study compared biomechanical and functional parameters of a total knee arthroplasty (TKA) implant (Cemented Zimmer Hi-Flex) against healthy older adults to determine whether knee biomechanics was restored in this patient population. Patients with a primary TKA and healthy adults >55 years old with no musculoskeletal deficits or arthritis participated. Bilateral knee range of motion (RoM) was assessed with a goniometer, then gait patterns were analysed with a 3D motion-capture system. An arthrometer then quantified anterior-posterior laxity of each knee. Statistical analyses were performed in SPSS (α=0.05; required sample size: n=21 per group).Abstract
Introduction
Methodology
Autologous chondrocyte implantation (ACI) is a common procedure, primarily performed in active, young patients to treat knee pain and functional limitations resulting from cartilage injury. Nevertheless, the functional outcomes of ACI remain poorly understood. Thus, the aim of this systematic review was to evaluate the biomechanical outcomes of ACI. Ovid MEDLINE, Embase, and Web of Science were systematically searched using the terms ‘Knee OR Knee joint AND Autologous chondrocyte implantation OR ACI’. Strict inclusion and exclusion criteria were used to screen publications by title, abstract, and full text. Study quality and bias were assessed by two reviewers. PROSPERO ID: CRD42021238768.Abstract
