The knee joint still hurts one year after the impact.

Generally, persistent pain in the leg joint one year after trauma may be related to factors such as osteoarthritis, bursitis, and bone fissures. A detailed analysis is as follows:

1. Osteoarthritis

Pain may be associated with the initial injury, as joint damage can lead to deformation and erosion of the bone surface, further exacerbating pain and inflammation. For mild symptoms, patients may take medications such as diclofenac capsules or aceclofenac tablets under medical guidance. In more severe cases, surgical intervention at a hospital may be required.

2. Bursitis

Following injury, bursitis may develop, which involves damage to the fluid-filled sacs (bursae) surrounding the joint. If left untreated or if it recurs, it may cause long-term pain. Patients can seek treatment at a hospital through methods such as ultrasound therapy or microwave therapy. In severe cases, surgical removal of the bursa (bursectomy) may be necessary.

3. Bone Fissure

Even without a complete fracture, impact trauma can result in a bone fissure. Bone fissures are a common issue among athletes and individuals experiencing chronic pain. In such cases, prompt surgical fixation at a hospital is usually required, along with reduced physical activity to allow sufficient time for bone healing.

In addition, persistent pain may also be caused by injuries such as cruciate ligament damage or fractures. It is recommended that patients seek timely evaluation at a qualified medical facility upon experiencing these issues. After identifying the underlying cause, targeted treatment should be carried out according to the doctor's recommendations.
