The feeling of weakness in the knee when walking four months after the comminuted fracture of the patella may be due to traumatic arthritis, joint adhesion and meniscus injury.
1. Traumatic arthritis: four months after the treatment of comminuted patellar fracture, may not be able to make the joint surface completely restore flat, so it is easy to occur traumatic arthritis, which will make the patellofemoral joint pain, and secondary quadriceps muscle atrophy, muscle strength decline when walking will have knee weakness symptoms.
2. Joint adhesion: If the fracture is not properly rehabilitated four months after the comminuted fracture of the patella, it will lead to the formation of adhesion in the joint, which will show the symptoms of knee weakness when walking.
3. Meniscus injury: If the comminuted patella fracture is accompanied by intra-articular meniscus injury, the meniscus injury will lead to walking four months after the fracture because the meniscus injury is not treated in time, and there is a lack of walking strength and leg weakness.
If the patient has a comminuted patellar fracture for four months, it may be due to muscle atrophy, etc., and the patient should have a follow-up consultation in time.
