【 摘 要 】

Instability - reported as a feeling of buckling or giving way - is a commonplace symptom in osteoarthritic (OA) knees, being found in up to 72% of individuals.1–5 In an attempt to understand and treat instability, either through total knee replacement (TKR), osteotomy or through physical therapies, it is important to define what is characteristic about the unstable in comparison with the stable OA knee. Since the first published incidence of instability in the OA knee,1 factors with potential association to instability have been examined such as joint laxity, muscle strength, proprioception, knee joint stiffness, disease severity and gait parameters, finding several significant associations.2,6-9 This is of importance as recent findings make clear that instability in the native knee has associations with poor function,3,10 and this instability may persist post-operatively after TKR with a nearly doubled rate of fear of falling, and significantly increased limitation of activities.5 Currently ‘patient-reported instability’ is the benchmark used in clinical studies as well as in clinical assessment.
