Overview
Knee pain is a prevalent musculoskeletal condition that significantly impacts the quality of life for many Australians. It is often a symptom of underlying conditions such as osteoarthritis, which is characterised by the degeneration of cartilage and changes in the bone structure within the knee joint. This degeneration leads to pain, stiffness, and reduced mobility [1]. The pathophysiology of knee pain involves complex biological mechanisms, including inflammation and the breakdown of joint tissues. Risk factors such as age, obesity, and previous joint injuries can accelerate these processes, leading to chronic pain and disability [2].
Statistics and Prevalence in Australia
In Australia, musculoskeletal conditions, including knee pain, affect approximately 29% of the population, equating to around 7.3 million individuals [1]. Osteoarthritis is the most common cause of persistent knee pain and is a leading contributor to disability, particularly among older adults [3]. In 2023, musculoskeletal conditions accounted for 12.8% of the total disease burden in Australia, highlighting the significant impact of these conditions on public health [1].
Symptoms and Clinical Presentation
Knee pain can present in various ways, ranging from mild discomfort to severe pain that limits daily activities. Early symptoms often include intermittent pain and stiffness, particularly after physical activity or prolonged periods of inactivity. As the condition progresses, symptoms may become more persistent, with swelling, reduced range of motion, and joint instability [4]. Red flag symptoms, such as sudden severe pain, inability to bear weight, or joint deformity, require immediate medical attention as they may indicate a more serious underlying condition [5].
Causes and Risk Factors
The primary cause of knee pain is osteoarthritis, a degenerative joint disease. Other causes include rheumatoid arthritis, gout, and traumatic injuries such as ligament tears or fractures. Risk factors for developing knee pain include advancing age, obesity, previous knee injuries, and genetic predisposition [6]. Obesity is particularly significant as it increases the mechanical load on the knee joint, accelerating cartilage wear and tear [7].
Diagnosis
The diagnosis of knee pain in Australia follows guidelines set by the Royal Australian College of General Practitioners (RACGP). A clinical assessment is the cornerstone of diagnosis, focusing on patient history and physical examination [4]. Imaging studies, such as X-rays or MRI, are reserved for cases with atypical features or when surgical intervention is considered [5]. Laboratory tests may be conducted to rule out inflammatory or infectious causes of knee pain [6].
Treatment Options in Australia
Treatment for knee pain in Australia is guided by evidence-based protocols that emphasise a combination of non-pharmacological and pharmacological strategies. Non-pharmacological treatments include patient education, weight management, and physical therapy to improve joint function and reduce pain [4]. Pharmacological options may involve the use of analgesics and non-steroidal anti-inflammatory drugs (NSAIDs) [5]. In cases where conservative management is insufficient, surgical options such as arthroscopy or joint replacement may be considered [6]. The Medicare Benefits Schedule and Pharmaceutical Benefits Scheme provide support for these treatments, ensuring accessibility for Australian patients [7].
Living with Pain In The Knee
Managing knee pain involves a comprehensive approach that includes regular monitoring, lifestyle modifications, and self-management strategies. Patients are encouraged to engage in low-impact exercises, such as swimming or cycling, to maintain joint mobility and strength without exacerbating pain [4]. Education on joint protection techniques and the use of assistive devices can further enhance daily functioning [5]. Psychosocial support and care coordination are essential components of patient management, addressing the emotional and social impacts of living with chronic knee pain [6].
Prevention
Preventing knee pain involves addressing modifiable risk factors and promoting joint health. Maintaining a healthy weight, engaging in regular physical activity, and avoiding joint overuse are key strategies [4]. Early intervention in cases of knee injury can prevent the progression to chronic pain, highlighting the importance of timely medical evaluation and treatment [5]. Public health initiatives aimed at raising awareness about knee health and promoting active lifestyles are crucial in reducing the burden of knee pain in Australia [6].
