Why hasn't a knee injury from a fall healed after more than 20 days, and what should be done?

It has been more than twenty days since the knee injury occurred, and it has not yet healed. This may be due to ligament damage, subcutaneous hematoma, or cartilage injury within the knee joint. Appropriate treatment methods should be selected based on the specific cause. Detailed analysis is as follows:

1. Ligament Damage

If the knee injury results in ligament damage, joint stability may deteriorate and joint effusion may develop. In such cases, strenuous physical activity should be avoided. Follow medical advice to undergo treatments such as massage, manipulation, acupuncture, and other therapies to promote recovery.

2. Subcutaneous Hematoma

If a severe subcutaneous hematoma develops, it may lead to excessive swelling of the knee joint, causing the aforementioned symptoms. Under a doctor's guidance, medications such as Shujin Huoxue Tablets, Amoxicillin Capsules, or Nimesulide Granules may be used. Alternatively, local puncture may be performed as recommended by a physician to facilitate resolution of the hematoma.

3. Intra-articular Cartilage Injury

If intense pain and swelling result from soft tissue damage within the knee joint and healing is incomplete, medications such as Dita Pills, Chondroitin Sulfate Tablets, or Glucosamine Hydrochloride Capsules may be used under medical supervision.

In addition, conditions such as osteoporosis or patellar fracture could also be responsible. It is recommended to promptly visit the orthopedic department of a qualified medical institution for proper diagnosis and treatment as directed by a physician.
