Why Do My Knee Joints Experience Redness, Swelling, Heat, and Pain Despite Normal Uric Acid Levels in My Health Check?

Physical Examination with Normal Uric Acid Levels, but Redness, Swelling, Heat, and Pain in the Knee Joint

Normal uric acid levels in a physical examination indicate that the redness, swelling, heat, and pain in the knee joint may be caused by intra-articular pyogenic infection, rheumatoid arthritis, or knee joint synovitis. Treatment should be tailored to the underlying cause. Detailed analysis is as follows:

1. Intra-articular Pyogenic Infection: When the body's resistance is low or after frequent joint punctures recently, intra-articular pyogenic infection can occur, manifesting as redness, swelling, heat, and pain in the knee joint. It is recommended to use Amoxicillin Capsules, Roxithromycin Capsules, Metronidazole Tablets, or similar medications under medical supervision. If the inflammation remains uncontrolled, joint cavity debridement under arthroscopy may be necessary to remove purulent tissue and further control the infection.

2. Rheumatoid Arthritis: Patients with rheumatoid arthritis may also experience redness, swelling, heat, and pain in the knee joint during acute episodes. Treatment typically involves Aspirin Tablets, Amoxicillin Capsules, Diclofenac Sodium Sustained-Release Tablets, or similar medications under medical guidance, along with ample warmth and protection.

3. Knee Joint Synovitis: Patients with knee joint synovitis may also suffer from redness, swelling, heat, and pain in the knee during acute episodes. Recommended treatment includes Synovitis Granules, Simiao Pills, Diclofenac Sodium Sustained-Release Tablets, or similar medications under medical supervision, which can be complemented by acupuncture therapy.
