Slight discomfort in the knee when standing with the leg straightened

In general, mild knee discomfort when standing with the leg straightened may be related to quadriceps tendinitis, knee synovitis, gout, and other conditions. Specific analyses are as follows:

1. Quadriceps Tendinitis

If proper warm-up exercises are not performed before physical activity, intense exercise can lead to excessive lactic acid buildup in the tendons, irritating surrounding tissues and causing aseptic inflammation. This condition can usually be relieved through rest and massage. For severe pain, nonsteroidal anti-inflammatory drugs (NSAIDs) such as celecoxib capsules or acetaminophen tablets may be taken orally under medical guidance.

2. Knee Synovitis

Knee synovitis is a joint disorder that may cause mild knee pain when standing with the leg extended. It is commonly caused by overuse or infection. If discomfort is significant, patients may use medications such as loxoprofen sodium tablets or compound lidocaine cream under a doctor's recommendation.

3. Gout

If a patient regularly consumes high-purine foods such as seafood and beer, uric acid levels may rise, gradually forming uric acid crystals in the joints, leading to knee swelling and discomfort. A light diet is generally recommended. Under medical advice, uric acid-lowering medications such as febuxostat tablets or benzbromarone tablets may be prescribed. In severe cases, surgical removal of the crystals may be necessary.

Besides the above, knee discomfort may also be associated with ligament injuries, meniscus tears, or tibial tubercle apophysitis. Patients experiencing these symptoms should promptly visit a reputable medical facility for evaluation and appropriate treatment to prevent worsening of the condition.
