To describe conceptions, as registered by a semi-structured interview, of exercise as treatment among sixteen middle-aged patients with moderate to severe knee osteoarthritis.
Sixteen patients (aged 39-64) with symptomatic, radiographic knee osteoarthritis and previous participants in an exercise intervention, were interviewed. The qualitative data obtained were analysed using phenomenographic approach.
Four descriptive categories containing 13 conceptions emerged: Category 1) To gain health included five conceptions; to experience coherence, to experience well-being, to be in control, to experience improved physical functioning, to experience symptom relief; 2) To become motivated included three conceptions; to experience inspiration, to be prepared to persevere, to experience the need to exercise; 3) To experience the need for support included three conceptions; to have structure, to receive guidance, to devote time; 4) To experience resistance included two conceptions; to hesitate, to deprecate.
Patients with knee osteoarthritis and knee pain, previously participating in exercise intervention, are aware of the health benefits of exercise, but have many doubts and concerns about exercise as treatment. These aspects should be considered when designing patient information and treatment programmes. Furthermore, a hesitative and resistive perception of exercise as a concept could have major influences on the implementation of health programmes.
"Potential barriers to exercise will also be addressed. Individuals with knee OA have expressed that pain or the fear of pain prevents exercise participation . Therefore, participants will use a pain monitoring scale to guide their home exercises, where zero represents “no pain” and ten represents “worst possible pain”. "
[Show abstract][Hide abstract] ABSTRACT: Background
Meniscectomy is a risk factor for knee osteoarthritis, with increased medial joint loading a likely contributor to the development and progression of knee osteoarthritis in this group. Therefore, post-surgical rehabilitation or interventions that reduce medial knee joint loading have the potential to reduce the risk of developing or progressing osteoarthritis. The primary purpose of this randomised, assessor-blind controlled trial is to determine the effects of a home-based, physiotherapist-supervised neuromuscular exercise program on medial knee joint load during functional tasks in people who have recently undergone a partial medial meniscectomy.
62 people aged 30–50 years who have undergone an arthroscopic partial medial meniscectomy within the previous 3 to 12 months will be recruited and randomly assigned to a neuromuscular exercise or control group using concealed allocation. The neuromuscular exercise group will attend 8 supervised exercise sessions with a physiotherapist and will perform 6 exercises at home, at least 3 times per week for 12 weeks. The control group will not receive the neuromuscular training program. Blinded assessment will be performed at baseline and immediately following the 12-week intervention. The primary outcomes are change in the peak external knee adduction moment measured by 3-dimensional analysis during normal paced walking and one-leg rise. Secondary outcomes include the change in peak external knee adduction moment during fast pace walking and one-leg hop and change in the knee adduction moment impulse during walking, one-leg rise and one-leg hop, knee and hip muscle strength, electromyographic muscle activation patterns, objective measures of physical function, as well as self-reported measures of physical function and symptoms and additional biomechanical parameters.
The findings from this trial will provide evidence regarding the effect of a home-based, physiotherapist-supervised neuromuscular exercise program on medial knee joint load during various tasks in people with a partial medial meniscectomy. If shown to reduce the knee adduction moment, neuromuscular exercise has the potential to prevent the onset of osteoarthritis or slow its progression in those with early disease.

"Our study population demonstrated a breadth of preventative knowledge, including the use of exercise and pharmacotherapy. Similar to symptomatic individuals, our cohort perceived physical activity to promote health gain, provide symptomatic relief and generate a sense of well-being
. The health benefits of physical activity included joint-specific effects such as improving muscular strength, joint flexibility as well as general effects like weight reduction and control. "
[Show abstract][Hide abstract] ABSTRACT: Background
The emphasis on prevention in English health policy continues to centre predominantly on major diseases such as coronary heart disease and diabetes. A number of key documents detailing self-management techniques and prevention of osteoarthritis (OA) are currently available, including the NICE guidelines and the Arthritis Foundation’s National Public Health Agenda for Osteoarthritis. However, few investigations have explored preventative knowledge of knee OA amongst the population. In particular, asymptomatic members of the population may use further information in considering how to prevent knee pain. This study considers perceptions around the prevention of knee pain amongst an asymptomatic population; this target population may provide alternative insights by which to stimulate preventative behaviours.
A sample of thirteen patients with no current knee pain was selected from responders to a population survey. Each interview was tape recorded and fully transcribed. Qualitative computer software package NVivo8 was used to manage the data. Thematic analysis was conducted using the constant comparative method.
The definition and causes of knee pain were interpreted in a multitude of ways. The importance of prevention was recognised by a sub-set, while a small proportion of participants negated the role of prevention. A range of social factors, including early adoption of actions, influenced the implementation and continuation of preventative behaviours. Individual responsibility for prevention was a key theme, although the role of society was also considered. Exercise was cited as a principal preventative strategy, although some participants viewed exercise as a destructive activity. A number of participants deemed pharmacotherapy to be harmful and at odds with normal physiology, instead preferring to adopt preventative behaviour over medication usage.
This asymptomatic population exhibit considerable breadth and variation in knowledge of preventative strategies for knee pain. Similarities in perceptions of prevention exist when comparing to the symptomatic population. These range from emphasis on individual responsibility, through to observations on the role of exercise and pharmacotherapy in knee pain. In general individuals are agreeable to act upon recommended treatments in line with NICE guidance. This receptiveness demands a greater consideration of preventative strategies in consultations, as well as wider availability and promotion of preventative strategies in order to improve the musculoskeletal health of the general population.

"Expectations on the results of treatments whether on their benefits or on their risks/side effects, also play a determining role when taking decisions on OA (Bower et al., 2006; Kroll et al., 2007; O´Neill et al., 2007). These expectations may come from external sources (doctors, friends, acquaintances) or the patient's own experience, for example over medication (Bower et al., 2006) or practicing exercise (Thorstensson et al., 2006). Different kinds of reaction to OA symptoms have also been detected (Karlsson et al., 1997). "
