A Randomised Trial Of Zoledronic Acid For Osteoarthritis Of The Knee
Funder
National Health and Medical Research Council
Funding Amount
$989,238.00
Summary
Osteoarthritis (OA) is the most common form of arthritis and is increasing markedly due to an ageing population. Despite its large disease burden, there are currently no approved disease-modifying drugs available which modify structural progression of OA. The aim of this study is to compare zoledronic acid treatment to placebo on knee structural change and knee pain over two years. It is hypothesised that zoledronic acid will reduce cartilage loss, knee pain, and bone marrow lesion size.
Young People With Old Knees: Knee Ligament Reconstruction And Early Joint Changes
Funder
National Health and Medical Research Council
Funding Amount
$782,727.00
Summary
Individuals who have undergone a knee reconstruction are at increased risk of knee osteoarthritis - 'younger people with older knees'. This may be partly due to increased knee load. This study aims to investigate whether muscle strength and activation as well as walking patterns influence changes in the knee joint structure as measured on magnetic resonance imaging. This may lead to rehabilitation strategies to address these factors so as to prevent the premature onset of knee osteoarthritis.
Using Magnetic Resonance Imaging (MRI) To Improve Understanding Of Knee Osteoarthritis And Develop Effective Therapeutic Treatments
Funder
National Health and Medical Research Council
Funding Amount
$299,564.00
Summary
Osteoarthritis is the most common form of arthritis and is increasing markedly due to an ageing population. This program of research uses magnetic resonance imaging (MRI) to improve our understanding about knee osteoarthritis. It will examine knee structural change over time using unique 10-year follow-up MRI measures from a pre-existing case-control study. This program of research will also examine two randomised controlled trials which aim to evaluate therapeutic treatments for the disease.
Does Vitamin D Supplementation Prevent Progression Of Knee Osteoarthritis? A Randomised Controlled Trial
Funder
National Health and Medical Research Council
Funding Amount
$1,016,758.00
Summary
Observational evidence suggests that vitamin D deficiency may have a role in the causes of osteoarthritis (OA) and there are biologically plausible mechanisms to explain this. There is, however, no evidence which shows that intervening with vitamin D supplementation can slow the progression of OA. This study will compare knee OA structural changes in patients receiving vitamin D supplementation with those receiving a placebo. Use of MRI will provide sensitive measures of knee OA changes.
Effect Of Lifestyle Factors On Knee Cartilage Volume And Rate Of Cartilage Loss In A Normal Population

Summary
Osteoarthritis (OA) has been described by the WHO as a potential epidemic and a major health and care services cost driver in an aging society. OA has the largest impact on burden of disease borne in later life. This has been acknowledged by its listing as the 7th health priority in Australia. To date, most research has focused on treating the resulting pain and disability. However, in order to reduce the burden of OA, identifying modifiable risk factors in the normal population is important.

OA has the largest impact on burden of disease borne in later life. This has been acknowledged by its listing as the 7th health priority in Australia. To date, most research has focused on treating the resulting pain and disability. However, in order to reduce the burden of OA, identifying modifiable risk factors in the normal population is important. This proposal aims to identify life-style factors, such as diet, physical activity and obesity that effect knee cartilage health in healthy subjects, thereby identifying potential targets for future prevention of OA. This will provide us with the opportunity to promote a better quality of life as people age and reduce the economic burden on the community.Read moreRead less
Does Low Dose Amitriptyline Reduce Pain In Knee Osteoarthritis? A Double Blind, Randomised, Pragmatic, Placebo Controlled Clinical Trial Of Amitriptyline In Addition To Usual Care
Funder
National Health and Medical Research Council
Funding Amount
$413,704.00
Summary
Pain is the main problem for people with osteoarthritis, a common form of arthritis. This pain is not controlled well. Pain comes from structural changes in the joint. However, after time, some people develop pain due to changes in the nervous system, called pain sensitisation. This is not affected by usual treatments. Amitriptyline is used to treat pain sensitisation. This study is a randomised trial to see whether amitriptyline, relieves pain in people with knee osteoarthritis over 3 months.
Footwear For Self-managing Knee Osteoarthritis Symptoms: The Footstep Trial
Funder

Funding Amount
$590,532.00
Summary
Self-management of symptoms is an important part of treatment for people with knee osteoarthritis. Footwear influences forces across the knee joint and it is unclear which types of shoes are best to minimise arthritis symptoms. This study will compare the effects of flat flexible shoes to stable supportive shoe styles on pain and physical function over 6 months in people with painful knee osteoarthritis.
Knee osteoarthritis (OA) affects about 30% of Australians over the age of 65, but also at younger ages. It causes joint pain and stiffness, especially on exercise. The cause is unknown but it results in loss of joint cartilage. There are few treatments available to stop the progression, which can finally result in need for an artificial joint. Most treatments such as paracetamol and non-steroid anti-inflammatory drugs (NSAIDs) reduce pain but have no effect on cartilage. NSAIDs can have serious ....Knee osteoarthritis (OA) affects about 30% of Australians over the age of 65, but also at younger ages. It causes joint pain and stiffness, especially on exercise. The cause is unknown but it results in loss of joint cartilage. There are few treatments available to stop the progression, which can finally result in need for an artificial joint. Most treatments such as paracetamol and non-steroid anti-inflammatory drugs (NSAIDs) reduce pain but have no effect on cartilage. NSAIDs can have serious side effects such as stomach ulcers and increased cardiovascular events (such as heart attacks). Fish oil has possible benefits in OA as it decreases pain and inflammation in rheumatoid arthritis (RA, another type of arthritis with joint inflammation and swelling), less use of NSAID in patients with RA, and in laboratory experiments may reduce cartilage breakdown in OA. It is likely that fish oil will have few side effects and decrease blood cholesterol. Many people with OA are already taking fish oil, however, there is no studies to know if it is effective in OA. The aim of this proposal is to study the effect of fish oil on pain and progression of knee OA, by doing a randomised clinical trial. Participants with knee OA will be given either high dose fish oil or similar oil with low levels of fish oil. The study will run for 2 years and during that time, we will measure pain and blood levels of fatty acids (part of the fish oil) and cholesterol. At the beginning and end of the study, magnetic resonance imaging (MRI) of the knee, a knee xray, and bone density testing will be done. The outcomes of the study will be to determine if fish oil affects pain and function (measured by questionnaires) and progression of OA (measured by cartilage changes on MRI). If fish oil is shown to reduce pain and disability and cartilage loss in OA, it will provide Australians with OA an alternative treatment that is low in side effects with positive effects on cardiovascular disease.Read moreRead less
