Investigating the prevalence of anxiety and depression in people living with patellofemoral pain in the UK: the Dep-Pf Study.

Background and aims Patellofemoral pain (PFP) is a common knee condition causing pain around or behind the kneecap which is exacerbated by certain activities. Traditionally it has been viewed as a self-limiting condition. Recent research proves this is not the case and the evidence for poor long-term outcomes is growing.

'If you can't help me, so help me God I will cut it off myself…' The experience of living with knee pain: a qualitative meta-synthesis.

Objective: To identify and explore the feelings and experiences of people living with knee pain as a precursor to exploring how this might contribute to improved care in the future.

Design: The qualitative meta-synthesis was undertaken in three parts (1) a systematic search of the literature, (2) a critical appraisal of the relevant studies and (3) meta-aggregation of the findings from the selected studies. A qualitative meta-synthesis is a process that enables researchers to answer a specific research question by combining and summarising a variety of qualitative sources.

The effect of closed-kinetic chain exercises and open-kinetic chain exercise on the muscle activity of vastus medialis oblique and vastus lateralis.

Patellofemoral pain syndrome (PFPS) is one of the most prevalent musculoskeletal conditions of the lower limb. The muscle imbalance between the vastus medialis oblique (VMO) and vastus lateralis (VL) muscles is one of the main factors leading to the development of PFPS. The disparity in research and the necessity to add to the existing literature base led to the development of this study.
