Symptoms of Knee Osteoarthritis
Knee osteoarthritis is characterized by a range of symptoms that can significantly impact a person’s daily life. These symptoms often worsen over time, gradually affecting mobility and reducing quality of life. Understanding the symptoms of knee osteoarthritis is crucial for early diagnosis and effective management.
Knee Pain: Pain is one of the most common symptoms of knee osteoarthritis. It can vary in intensity, from a dull ache to sharp or intermittent pain. Vigorous activity or excessive strain on the knee joint may worsen the pain.
Swelling and Stiffness: In addition to pain, knee osteoarthritis can cause swelling and stiffness in the affected joint. The knee may feel swollen and appear larger than usual. Stiffness can make it difficult to bend or straighten the knee, leading to limited mobility.
Trouble Moving the Joint: As knee osteoarthritis progresses, individuals may experience difficulty moving the affected joint. This can manifest as a reduced range of motion, making it challenging to perform daily activities such as walking, climbing stairs, or kneeling.
Gradual Decrease in Mobility: Over time, knee osteoarthritis can gradually decrease a person’s mobility. The joint may become less stable, affecting balance and coordination. This can lead to a decrease in overall physical activity and the ability to engage in normal daily routines.
Other Symptoms: In addition to pain, swelling, stiffness, and reduced mobility, knee osteoarthritis may present with other symptoms. These include grinding or popping sounds (crepitus) when moving the knee, muscle weakness around the knee joint, sudden swelling or locking of the knee, and a feeling of the knee giving way during movement.

It is important to note that knee pain and stiffness are often more pronounced in the morning, after periods of rest or prolonged sitting. However, these symptoms tend to improve with movement and activity.
Diagnosis and Classification of Knee Osteoarthritis
When it comes to diagnosing knee osteoarthritis, healthcare professionals typically rely on a combination of the patient’s history, physical examination findings, and imaging features. This comprehensive approach allows for a more accurate diagnosis and helps guide appropriate treatment strategies.
One of the most common imaging techniques used to confirm the diagnosis of knee osteoarthritis is X-ray imaging. X-rays provide detailed images of the knee joint, allowing clinicians to assess the extent of joint damage and evaluate the severity of osteoarthritic changes.
It’s important to note that knee osteoarthritis can be classified into two main types: idiopathic (primary) and secondary. Idiopathic knee osteoarthritis refers to cases where the exact cause is unknown, whereas secondary knee osteoarthritis occurs as a result of underlying conditions or predisposing factors. In the diagnostic process, healthcare professionals need to rule out any underlying disorders that may contribute to the development of secondary knee osteoarthritis.
The clinical diagnosis of knee osteoarthritis is based on the presence of typical symptoms, physical examination findings, laboratory results, and imaging features. These factors collectively support the diagnosis and help guide appropriate management and treatment plans for individuals with knee osteoarthritis.
