Left Knee Pain: Causes and When to Seek Medical Advice - Orthopedics

More Info

Understanding left knee pain can be complex, as it may arise from various underlying causes. Based on your description, it seems that your left knee pain has been persistent for three months, particularly noticeable when bending, such as when squatting and standing up. The pain's intensity correlates with the duration of the knee's flexion, and you report no pain when standing or lying flat. Additionally, you have begun to experience discomfort in your thigh and hip, with occasional pain radiating down to your ankle.

Given these symptoms, several potential causes could be at play. One possibility is patellofemoral pain syndrome, which is common among individuals who engage in activities that involve repetitive knee bending. This condition can lead to discomfort around the kneecap, especially when bending the knee under load. Another consideration is osteoarthritis, which can cause pain and stiffness in the knee joint, particularly after periods of inactivity or after bending the knee.

The absence of localized pain upon palpation suggests that the issue may not be related to a specific injury or acute trauma. However, the pain radiating to your thigh and hip could indicate that the problem is not isolated to the knee joint itself. It may involve the surrounding muscles, tendons, or even the hip joint. Conditions such as bursitis or tendonitis in the hip area could contribute to referred pain in the knee.

You also mentioned a history of back issues, including past strains and discomfort in the cervical and lumbar regions. This history is relevant, as spinal problems can sometimes lead to referred pain in the lower extremities due to nerve involvement. For instance, a herniated disc in the lumbar spine could potentially irritate nerves that affect the leg, leading to pain or discomfort in the knee, thigh, or ankle.

Regarding your question about bone spurs, while they can develop due to chronic joint stress and may contribute to pain, they are typically associated with osteoarthritis. An X-ray can help identify bone spurs and assess the overall condition of the joint, including any signs of arthritis or other degenerative changes.

In summary, your symptoms could stem from a combination of factors, including patellofemoral pain syndrome, osteoarthritis, or referred pain from spinal issues. It is advisable to seek medical attention, particularly from an orthopedic specialist or a physical therapist, who can perform a thorough evaluation. They may recommend imaging studies, such as X-rays or MRIs, to better understand the underlying cause of your pain. Treatment options may include physical therapy, anti-inflammatory medications, and activity modifications to alleviate symptoms and improve function.

In conclusion, while your symptoms may not indicate a severe condition, they warrant further investigation to determine the exact cause and appropriate treatment. Early intervention can help prevent the progression of any underlying issues and improve your quality of life.
